Family Fun at Lake House Part 1

Every summer my family which includes my dad, step mother and step sister travel to my aunt's lake house. As a kid it was always a fun time, playing in the lake, roasting marshmallows and what not, but as an 18 year old horny teenager. Not so much. I don’t know what had gotten into me at that time but I was hornier than ever. I was masturbating twice the normal amount. As much as I hate to admit it, I found myself staring at my step mom and step sister, a lot. I was very shy and didn’t talk to girl's, my stepmom and sister were the only vice I had at the time.

First a little back story, my dad and step mother married when I was very young. For as long as I can remember they were together and Annie had always been my sister. Annie and I were the same age and were always very close growing up. Annie and my step mother Amy were younger and older versions of each other. Both had long, luscious and wavy blonde hair. They each had pale skin with tiny freckles as well as the same sized breasts. I found this out one day when I was extra horny. Nobody was home and I decided to use both their panties to masturbate with, while stealing the panties I checked out both my step sister and step mothers bra sizes, 36DD’s.

Admittedly, I felt guilty about my depraved taboo acts and thoughts toward my step mother and sister. I tried to avoid them and situations that involved being around them. But then I found myself stuck in a car with them. The drive was long and tortures. Annie was dressed in a tight white tank top that her breast's pretty much overflowed the top. As well as tiny daisy duke style jean shorts. I tried to not stare, I didn’t want to get a hard on in the car.

We finally arrived at my aunt's lake house. We all got out of the car and eased our achy backs. I glanced over at my sister and mother arching their backs and got a good view of each of their hefty chests. I felt my cock twitch inside my cargo shorts.

“Alright, let's go say hello then Jake (that's me) and I will bring the bags inside.” My dad announced.

We knocked on the lake house door and it opened. My aunt Lisa stood at the door, wearing only a bikini and tiny robe. Aunt Lisa was my step mom's older sister and looked identical to her. I blankly stared at her busty chest and toned stomach, my cock twitched again inside my shorts. We each said our hello's then the ladies went inside as my dad and I grabbed the bags.

I grabbed Annie's bag as well as mine and my dad grabbed his and my mom's luggage. We carried them inside.

“Jim (my dad) you and Amy will be in the guest bedroom upstairs. Jake, you and Annie will be bunking with Becky in the basement.” My aunt Lisa said.

I carried the bags down to the basement, when I arrived I found Annie as well as my cousin Becky. I hadn’t seen Becky in a long time. Becky was older than me by a few years and had been away at college. My jaw dropped when I saw her. She was tall for a girl, maybe my height 5’8. Her hair was double braided. She was wearing a crop topped tank with tiny shoulder straps showing off her tight stomach and belly button. Her chest was a bit smaller than Annie's but not by much. Her leg's were long and muscular.

“Jake! It's been so long!” Becky said as she ran over to me as I reached the bottom of the staircase.

I placed the suitcases down and Becky wrapped her arms around me and hugged. I felt her soft, perky breast’s press against me. I felt a bolt of excitement shoot through my body and into my cock. “Please don’t get hard" was all I could think.

Becky broke the hug . “Wow you and Annie really grew up!” Becky said as she looked up and down at me.

I could've sworn I had a tiny hard on as I hoped it was visible to my cousin. The rest of the afternoon Annie and I caught up with Becky. Becky told us stories about college parties and her volleyball team that she was the captain of.

The day fell into night. We had a family barbecue then Becky suggested a walk on the lake's beach to Annie and myself. We agreed and the three of us went outside into the night time summer air.

“Hold on one second.” Becky whispered.

We watched her run to her car and grab some kind of beach bag that she threw over her shoulder and returned to us.

“Alright let's go.” She said.

I was confused and curious why she grabbed a bag and what was inside it. We walked down to the lake and kicked our shoes off and stepped barefoot onto the sand. The sand was still warm from the now gone summer sun. The lake was large and each lake house was pretty isolated and spread apart. There was medium sized wooded area's that separated each house. We walked toward the wooded area to our left and Becky stopped.

“Over here, follow me.” She said.

Annie and I followed our older cousin blindly until we reached a little out cove near the wood's on the beach, overlooking the lake. There was four tree stumps that mimicked stools around what looked like a fire pit. Becky sat down and Annie and I followed her lead.

Then, Becky set the bag down onto the sand and reached in to pull out a bottle of alcohol.

“Oh you brought vodka!” Annie announced.

I was not really a big drinker. A couple of my also shy friend's stole a few beers from one of their dad's once or twice, but that was all. I wasn’t sure if Annie had drank but I figured she did sometimes with her friend's. Annie was always more outgoing and adventurous than me.

Becky popped the top of the bottle containing clear liquid. My older cousin than brought the bottle to her lips and gulped, once, twice and third time.

“Wooo!” She called out while making a sour looking face.

Becky passed the bottle to Annie. Annie took it eagerly and gulped the liquor down like a professional. I was impressed. Then Annie passed the bottle to me. I was actually nervous, as I had never drank hard liquor before. I breathed in and out and sipped it. I instantly coughed and grimaced like an amateur.

Becky and Annie giggled. “Take another sip Jake, the first one is always the worse.” Becky said still giggling.

I did as she said. I tried to be brave and took a much bigger sip the second time. I felt the harsh liquor burn my throat but I managed to take another gulp.

“Woah.” I said as I grimaced again.

Annie and Becky giggled some more. I handed the bottle back to Becky who practically chugged it. Annie did the same. I skipped my turn a I was already feeling the effects. Benefits of being a light weight I guessed.

We sat around the fireless pit and Annie and Becky talked some more, about boys or something. I wasn’t really paying attention because I was feeling pretty woozy and buzzed.

My attention was brought back when Becky said, “how about a night swim!”

“But we don’t have our swimsuits.” Annie replied.

“We’ll just go in our undies, their practically swimsuits anyway.” Becky answered.

“Screw it! Let's do it!” Annie said, as she took another pull from the vodka bottle.

Becky and Annie both stood up and ripped their shirts up over their heads and off. I couldn’t believe what I was seeing. Becky was wearing a little too small yellow bra. Annie had on a neon green bra. I felt my cock twitch at the sight of my sister and cousin's busty chest’s. They then unbuttoned their jean shorts and pulled them down. They each had matching panties to their bra’s. My cock twitched some more and hardened a bit. My face was red. I was panicking, I had a semi hard on and now I had to take my shorts off in front of my sister and cousin, both being the reason why I was stiff.

“Come on Jake! It's not like we haven’t seen you in your undies.” Annie teased and giggled.

I sighed and stood up and removed my shirt. I felt like both Annie and Becky’s eye’s were glaring at my upper body a little longer than what felt normal. I was in really good shape. Since I was such a shy guy, I thought maybe working out would give me some confidence but that just turned into a crazy obsession with weight lifting. My chest was strong, my arm's were ripped and veiny. Then there was my favorite feature of mine, which was my six pack abs.

“Wow, you did grow up little cousin! Do you live in the gym?” Becky said.

“He spends hours in our garage gym, it's insane.” Annie added.

Both girls were still staring at my body, my face was turning red. My cock was still at half mass in my shorts. I gulped and unbuttoned my cargo shorts and pulled them down. I had on a pair of bright blue boxer briefs. I looked down and saw an outline of my cock's head and a bit of my shaft, I felt my face grow even more red.

I looked up again and Annie and Becky were still staring but now their eye's were on my crotch. I wanted to die. I had to do something, I grabbed the bottle from the sand and took another two swigs of the vodka.

“Last one to the water is a virgin!” Becky announced.

She then took off sprinting down the beach. Annie followed her. I was a virgin but didn’t want to lose. I took off sprinting but the girls head start allowed them to beat me. I watched both their thick asses jiggle while they ran. Becky hit the water first, she reached the lake and dove in. Then Annie. Finally, me. The lake water was a little cold but felt nice. I dipped under the water then resurfaced. Annie and Becky were swimming around.

We splashed around in the water for what felt like an hour. Eventually we got a little too cold and decided to get out. We walked back to our spot and Becky, then Annie took some more gulps of the vodka. I watched them. I could see they were cold, their nipple's were poking against their wet bra's. My cock hardened a bit again in my wet boxer's.

I too sipped some more vodka. I noticed the girl's glancing at my body and crotch. I couldn’t help myself from taking peaks at their wet tit's and pussies. I was able to even see the lines of their lips because the wet fabric was clinging to their skin.

Once we were somewhat dry, we re-dressed and headed back to the house.

“What are we going to say to our parents? They can’t know Jake and I were drinking.” Annie said.

“Oh shit that's right, we'll get in trouble.” I added. I was feeling really wobbly and pretty drunk.

“We'll sneak in through the side door where the hot tub is. They're probably all drunk themselves anyway.” Becky said as the leader.

We did just that. The three of us snuck around the house. We came up to a little gate. Becky opened the gate and led us down a concrete staircase. We arrived outside the basement door. Outside the door was a little platform that the moonlight lit up, creating a spotlight for the covered hot tub Jacuzzi.

“Should we warm up in the hot tub?” Becky suggested.

“Sure, that sounds nice.” Annie added.

“Sure.” I said, slurring my words a bit.

Becky walked around the tub and hit a button. A mechanical noise came from the tub and the cover began to slowly uncover the water. Becky pressed another button and the jets went on causing the water to ripple. She pressed a third button and after a few minutes steam began to come from the water.

“Well, our undies are already wet so screw it.” Becky said, as she pulled her slightly wet shirt off, then her shorts.

Annie did the same thing. Both girl's quickly stripped to their already wet underwear. I looked at their bodies again. Another bolt of excitement went through my body and my cock stiffened. I breathed hard again and pulled my shirt off, then like a bandage I pulled down my shorts.

Again, Annie and Becky both stared longer than they should’ve at my body and crotch. My cock twitched from their staring. I could have sworn they both smirked and giggled. Becky and Annie climbed into the hot bubbly water. I followed them. The three of us sipped more and more from the vodka bottle, about half the liquor was gone.

We sat in the water in silence for a while, until.

Becky said, “how about a game?”

“What kind of game?” Annie asked.

“Truth or dare?” Becky said.

“Isn’t that like, childish?” Annie asked again.

I just listened quietly.

“Yeah, but it might be fun!” Becky said.

“Alright I’m game!” Annie said. “Jake, you down?”

“I never played before.” I said.

Becky giggled. “Alright we'll show you. I'll go first. Annie, truth or dare?”

“Truth.” Annie said.

“Lame. But fine. How many boys have you kissed?” Becky asked.

“Becky, my brother is literally right next to me.” Annie protested.

“Annie, we're all in our underwear together. I don’t think boundaries really matter at the moment. Jake, you don’t care right?” Becky said.

“I guess it's okay.” I said.

“Alright fine. Uhmm, I've kissed, four boys.” Annie confessed.

I said nothing.

“Alright now you go Annie.” Said Becky.

“Alright, truth or dare Becky.”

“Dare me!” Becky said smiling.

“I dare you to, uhmm. I dare you to get out of the hot tub and do twenty jumping jacks!”

“Easy!” Becky said. She then climbed out of the hot tub. Annie and I watched on.

“Ready, set, go!” Annie announced.

Becky began doing jumping jacks. She jumped and her legs spread as her arms simultaneously went up above her head, then she closed her leg and her arms came back down to her sides. Each time she did a jumping jack, her tit's jiggled and flopped. I was mesmerized by the sight. I felt my cock stiffen again, almost fully.

Annie was counting out loud for each jumping jack Becky did. “And twenty!”

Becky then hopped back into the hot water and rejoined us.

“Okay, see how the game works Jake?” Becky asked me. I nodded and she asked me, “truth or dare?”

“Truth.” I said.

“How many girl's have you kissed.” She asked.

My face got red with embarrassment. Not only was I a virgin, but I had never even kissed a girl before. I sat in the hot water with my busty sister and cousin with a hard on and shame. I thought about lying but I finally said, “none, I haven’t kissed any.”

“Aw, that's okay nothing to be embarrassed about! My last boyfriend didn’t have his first kiss until he was twenty and he was my best lover. Not a bad thing to be a late bloomer! Becky said, trying to comfort me. “Now you can ask me or Annie.”

“Uhm, okay. Annie, truth or dare?” I asked my step sister.

“Dare!”

I thought for a long moment. What could I dare her to do. I felt drunk and downright horny. It must've been the alcohol in me or the lust, because what came out of my mouth shocked even myself.

“I dare you and Becky to trade bra's.” I said, somewhat shyly.

Both girl's started giggling and looked at each other.

“Okay!” Annie said.

“That's fun!” Becky said.

They both turned their backs to me. I couldn’t deny that I was let down by the fact that I couldn’t see. I watched as they both reached up behind their backs and unclasped the clips. The both pulled their arms out and swapped bras. Then, they both re-attached their new borrowed bras. My sister and cousin turned around and the view was incredible. Becky's bra was a little too small for Annie, her tit's were overflowing the wet bra. But Annie's bra on Becky was a little too big but Becky accidentally put my sister's bra on a little too low which caused the inner parts of her areola's to show.

I didn’t say anything about Becky's pink areola's being visible and to my surprise neither did Annie.

“Alright, my turn. Becky, truth or dare?”

“Dare again!”

Annie giggled to herself and smiled. “I dare you and Jake to trade bottoms!” She said laughing like an evil scientist.

“What! No! I don’t want to wear girls underwear, that's weird.” I protested.

“Well if you don’t do a dare there are consequences.” Becky said as she reached under the water with her hands, then pulled her yellow panties up and out of the water.

Becky dangled them teasingly.

“What kind of consequences?” I asked nervously, as I stared at my cousins panties.

Annie thought for a long moment. “If you don’t do the dare, we're going to draw on your face while you're asleep! And not nice things. Then, tomorrow our parent’s and aunt will see a cock drawn on your forehead.”

“That's evil sis.” I said.

I sighed and reached below the water and removed my boxers, freeing my almost fully erect cock beneath the bubbles.

Luckily, the jets were turned up too high so nobody could see anything. I pulled my boxers out of the water and Becky snatched them. I took her yellow panties. We both slipped on each other's underwear. Becky's thong was silky and soft. The panties felt nice on my cock. My cock hardened more and throbbed.

“These are comfy cousin!” Becky teased, “how do my panties feel?” She said giggling.

My face was red from embarrassment, or the heat from the water, or the vodka. I just said nothing.

“Alright Annie, truth or dare?” Becky asked.

“Dare!” Annie said.

“Well, since Jake has never kissed a girl before.” Becky began.

“No! No Becky, not happening!” Annie said cutting her off.

“Oh come on, you guys aren’t blood related. Plus, do you want your Step brother to finally kiss a girl he really likes or loves and he doesn’t know what to do? That could ruin everything for him. Think of it more as a teaching experience.” Becky said.

Annie and I both just sat in the steamy, bubbly water awkwardly.

“Well, I don’t want that to happen.” Annie said. She paused and thought for a long time then said, “okay fine. But this never leaves this hot tub, like ever!”

I gulped. I was insanely nervous. I couldn’t believe Annie just agreed to kiss me. My step sister, who I have known my entire life was about to be my first kiss.

Annie slid through the bubbly water close to me. I felt her breast rub up, against my arm. My cock was throbbing and pushing against the thin fabric of my hot cousins panties.

First Annie grabbed the vodka bottle and practically chugged it. She handed me the bottle, I did the same as I was incredibly curious and nervous.

“Alright Jake, close your eyes.” Annie instructed.

I did just exactly that. I closed my eye's and waited. A few second's later I felt her soft, wet lip's on mine. A jolt of electricity shocked through my body and cock. Her lip's twisted and glided on mine. I felt her tongue push through my lips and against my own. Her tongue was slick and she worked her tongue on mine. I tried my best to mimic her actions. I even heard her moan softly into my mouth.

Then she broke the kissed. Annie and I were breathing heavily. We both looked at Becky, who's chest was also heaving as she breathed.

“Uhm, okay. Wow, guys.” Becky said. “Annie, your turn.”

Annie was quiet for a long moment, her body was squirming a bit beneath the water.

“Is she turned on?” I thought as my cock was throbbing and I felt more horny than I ever had in my entire life. I felt like I was going to blow my load right there and then.

“Becky, truth or dare?” Annie asked.

“Dare.” Becky said.

“Well, I've never kissed a girl before and since we're teaching and learning. I dare you to kiss me.” Annie said.

Becky and myself were stunned by Annie's dare.

“You have kissed another girl before right, Becky?” Annie asked.

“I have. And okay. Let's do it.” Becky replied.

I couldn’t believe what I was hearing. Then, what happened next, I couldn’t believe my eye's. Becky and Annie shifted in the water next to each other. Annie brushed her blonde hair behind her ear. My sister and cousin both closed their eye's and moved their faces in close.

I watched as their lip's met, just as Annie and my own had. Their pink lip's connected and flowed against each other. I saw both Annie and Becky's tongues dance as they French kissed. Becky placed her hand's on Annie's hips. Annie did the same. My cock was throbbing hard, my head was spinning.

They finally broke the kiss and stared into each other's eye's. They both started to giggle.

“Damn cousin, you’re a great kisser.” Becky said boldly.

Annie's face was bright pink. “You too Becky.”

“Okay, my turn right?” Becky asked. “Jake, truth or dare?”

I couldn’t contain it any longer. I couldn’t tell if it was the alcohol or the fact that I had kissed my sexy step sister or watched my step sister kiss my equally as sexy cousin but my confidence was bursting at the seams.

“Dare.” I said.

Both girl's “ooh’d" and “ahh'd.” From my sudden boldness.

Becky stared at me with evil like intent. She reached up and turned the hot tub jets off. The water simmered to a stop.

“I dare you to show us your cock.” Becky said.

“Becky! What the hell!” Annie said.

I said nothing, my face was on fire.

“What, like you've never thought about it. I mean, if he wasn’t my cousin, I'd definitely bang him. I saw you looking at his body and bulge on the beach, just like me. Come on Jake, let's see what you're packing!” Becky said.

Annie's face was as red as mine. She said nothing to what Becky said. Annie didn’t protest to me showing her and my cousin my cock. I couldn’t believe what was happening. Then, Annie handed me the vodka, which was almost empty. I took a long pull from it and gulped.

I breathed hard then, pulled my cousins panties down and off. They floated to the surface of the water. Both Annie and Becky just stared through the water at my erection.

“Wow.” Becky said.

“Oh, my.” Annie added.

“What?” I asked.

“It's, well, huge.” Becky said.

“Yeah, wow.” Annie said.

“How big are you?” Becky asked.

“I don’t know? Eight inches?” I said. Even though I did know, I measured it one day.

“Can I touch it?” Becky asked.

“Uhm, I don’t know.” I replied.

Becky didn’t wait for an actual answer. She moved in the water close to me. I felt her finger's lace around my shaft.

“Ohhhh.” I moaned from the feeling of somebody else's hand on my cock for the first time.

“Wow, it's so thick.” Becky said as her hand started to slide up and down on my cock.

“Ohhhh.” I moaned again.

“Let me feel.” Annie said.

Becky let go and Annie replaced her hand on my cock.

“Ohhhh.” I moaned again.

“Wow, this is the biggest cock I’ve ever seen.” Annie said, as her hand began to stroke my shaft.

Annie continued to stroke my cock slowly. I felt like I was about to cum but then she stopped. I was disappointed. My cock was rock hard and pulsating.

“Uhm, uh, Jake. It's your turn.” Becky said, her word’s cutting through the awkward, sexual tension.

At that point, I was so horny and needed release. But I also wanted to see how far this game could now go.

“I dare you both to take your tops off.” I said.

“No, I’m not showing my brother my tit's.” Annie protested.

“Annie, not for nothing, but you just rubbed his cock. It's only fair.” Becky replied as she reached behind her back and unclasped her bra.

Annie's bra that Becky was wearing fell to the water. Annie and I both stared at her bare tit's. Her tit's were amazing. Definitely large C-Cup's. They were a perfect tear drop shape. Her nipple's were tiny, pink and hard.

“Woah.” I said under my breath.

“Oh fuck it.” Annie said as she reached behind her back and unclasped Becky's borrowed bra.

The yellow and borrowed bra fell to the water as well as my jaw. My step sister's tit's were perfect. They were large, perky and beautiful.  Her areolas were slightly large and her nipple's were long and hard.

“Oh, my.” I whispered to myself.

“Wow Annie. They're amazing.” Becky added. “Guy's, I’m not going to lie. I'm so fucking horny right now.

“I hate to admit it but so am I.” Annie said.

I just nodded to agree. I was in fact incredibly horny.

“We could masturbate." Becky said. “Just like everything else that happened in this hot tub, it will stay in this hot tub.”

Annie and I said nothing.

Becky reached below the water and removed my boxer's that she was wearing. Then, she sat up on the railing of the hot tub. She placed one foot onto the ledge and spread her leg's.

“Well, I'm doing it with or without you guys. I need release.” She continued as she brought to finger's between her pussy lip's.

Her pussy lip’s were amazing and shaved. I could see the moisture. Her finger's ran between her lip's, up and down.

“Mmmf.” Becky moaned.

I couldn’t hold it any longer. I followed her lead and sat up onto the ledge across Becky. I grabbed my cock and began to jerk it slowly.

Annie just watched us. Her head turned to her cousin, then to her brother. Both of us masturbating and moaning. Annie finally gave in. She reached down below the water and removed her panties. Annie sat her nice ass onto the ledge of the tub. Her pussy was light pink and shaved as well. Annie ran her finger's through her wet slit.

“Mmmmmfffff, oh my god.” Annie moaned.

I jerked my cock faster and faster. Becky as well as Annie's finger's moved smoothly and expertly between their lip's. Both my sister and cousin were circling their finger's in clockwise motion's against their clit's.

“Ohhhhhh! Ohhhhhhhhh!!!” Becky cried out.

Her body was shaking. Her leg's trembled. Her orgasm blasted her hard.

“Ahhhh!!! Fuck!!! Annie moaned loud.

I watched my step sister's body buck and shake, just like my cousin. Her head was rocking back and forth. She was trembling like crazy as she reached orgasmic bliss. I couldn’t hold it any longer. My hand was gliding up and down my cock like mad man.

“Ohhh! Mmfff! Aghhh!” I moaned out.

My cock pulsed and throbbed in my hand. My ball's tightened and hot cum, shot from my tip into the hot tub water. Rope after rope. Load after load. My leg's felt weak.

“Wow! That was incredible.” Becky said breathlessly.

“Yeah, that was the hottest thing I've ever done.” Annie added.

I just breathed hard and heavy.

Becky shut the hot tub down and put the cover back on. The three of us walked naked into the basement and dried off. We each used the bathroom and redressed. We each took up a spot on the couches and passed out.
