Older sister warned me her friend was trouble, but that wasn't gonna keep me away from her

This story takes place many years ago in 2013. I was 18, just graduated high school, and was on my way to move to Tennessee and play baseball in college. My sister had just graduated college and was hosting a party at our parents' house. At the time I was a completely different person from who I am now - I was mostly pretty introverted and didn't really go to all that many parties, especially full of people I hadn't met before. My last girlfriend and I had also just recently decided to break up since we were going to be moving states away from each other, so I was pretty much just in the mood to sit in my room and play Halo all night.

"Come hang out for a bit," my sister urged. "I'll even let you drink, but don't tell mom and dad."

Even as a youngster I knew that a drink or two was enough to change that introvert into an extrovert. Eventually I learned how to do it even without alcohol, but at the time I figured I could get one beer in me early and feel comfortable enough to go for a couple hours at least.

That's exactly what I did, and as the guests came rolling in, I was happy to join in the celebrations and talk about what my plans were for college with all these people who were on their way out of it. That's when I met one girl in particular who stood out to me: Shawna. She was 24, blonde, very short and petite. My sister pulled me aside.

"She's trouble, stay away from her," she told me. Really? You're going to tell an 18-year-old boy that and just assume he's gonna leave her alone? That's not how this works.

I quickly learned what my sister meant by that when Shawna and I passed each other in a narrow hallway of our house. I had just come out of my room after changing into my swim trunks, and she was coming out of our bathroom after switching to her little red bikini. Our bodies up against each other, she looked up at me in awe.

"Holy shit, you're really tall. Or I'm just really short," she said.

"I think it's a little of both," I said.

She laughed, then looked down. "If I were just a couple inches shorter, I'd be the perfect height," she said before walking away. I'll admit, I had no idea what the fuck that meant at the time, and it bothered me for the rest of the night.

She was certainly the life of the party. Every game involved her yelling and getting animated at some point. No story was complete without her infectious giggle. I wasn't the only guy she made little passing remarks at, either. I think almost every guy there got at least some compliment or comment that made them raise an eyebrow at some point.

At one point, there was a good group of us all in the jacuzzi trying to see how many of us could fit in there at once (it was actually a shockingly high number for a relatively small jacuzzi). This left Shawna's back pushed directly up against me.

"Oops, sorry. But I'm sure you won't mind," she said. Maybe it was just my mind playing tricks on me, but I swear she started subtly grinding her ass against me. I pulled my hips back as far as I could manage to keep my raging erection from pressing against her, and I'm sure she knew exactly what she was doing.

As everyone else cycled out, it eventually ended up being just the two of us left. The water level dropped sharply until our chests were showing, but I tried to keep my eyes anywhere else.

"So do you have a girlfriend?" she asked.

"No, we just broke up actually," I said.

"Aww, well, she's missing out."

"It was kind of mutual. Going to different schools and all that."

"Why didn't you guys wait until the end of summer? That's a lot of time you could be fucking with no expectations, now you have to go look for other people to fuck. Unless that's part of the plan."

I looked her up and down and a smile grew on my face, "my sister was right to warn me about you. You're trouble."

She moved closer to me, put her hand on my thigh, and whispered in my ear, "you don't even know the half of it."

"I'd like to."

She moved back, "easy now. Listen to your sister."

"Fair enough," I said, looking back at the rest of the party sitting around the campfire. "I should probably... uh... go."

I climbed out of the water and toweled off, trying desperately to conceal my erection. Once I was dry enough, I wrapped the towel around my waist and went inside. I shut myself in my room and laid down on my bed, my head still buzzing from everything and my social battery nearing its limits.

It didn't take long before I heard a knock on my door.

"Bathroom's at the end of the hall," I shouted.

The door creaked open and Shawna's head poked in. "Do you mind?"

"Yeah, sure, come in."

She looked both ways down the hall before slipping in and quietly closing the door behind her. I sat up in my bed and got a good look at her. Her wet blonde hair draped down her back, her body now wrapped in a towel.

"I just wanted to say, I hope I didn't offend you by talking about your girlfriend. I don't know your guys' situation," she said as she sat at the edge of my bed beside me.

"No, you didn't say anything bad."

"You left in such a hurry."

"I didn't mean to, I just needed to rest for a minute."

"Good," she said, resting her hand on my leg again. My cock jumped once again, concealed by my trunks and towel.

"Is that the only reason you came in here?" I asked.

"What other reason would there be?" she asked. She tilted her head and started rubbing my leg.

"You know what you're doing."

"What am I doing?"

"There's a very good reason I left in a hurry and rushed to wrap this towel around me."

"What reason is that? Are you hiding something?"

I unwrapped the towel and flung it open, revealing a bulge in my swim trunks.

"Oh wow."

She pulled her hands back and rested them on her lap. I looped my thumbs under the waistband and motioned like I was about to pull them down but I stopped to see how she'd react. She nodded, and I pulled my shorts down, letting my cock slap against my stomach on the way down. I took them off all the way, wrapped them in the towel, and threw them down.

She reached one hand over and wrapped it around my cock, giving it a light stroke. I bit my lip and watched her petite fingers try their best to grip all the way around.

"Is this what you wanted? Is this why you've been staring at my body all night?" she asked.

"Not a lot to see right now," I said, tugging at her towel. She let it drop to the ground, her body glistening with little wet spots on her pale white skin. She reached around and tugged the string in the back that held her bikini top on, exposing her tits to me for the first time.

"You like that? I might be an old lady to you but they're still firm and bouncy," she said while bouncing on my bed, her small tits jiggling along with her.

"You're not old, just... experienced."

"Oh really now? How often do you think I do this?"

"Enough to earn a reputation with my sister."

She laughed. "Okay, there was that one party. And the other one. But I never fuck anyone at any of these parties. That's irresponsible. You're gonna need to learn that."

"What do you do, then? Just tease?"

"No, I usually do this," she said before leaning down and wrapping her lips around my cock. I rested my head back on my pillow and moaned. She climbed up on the bed so she was kneeling on all fours, her ass facing up toward the door and her face in my lap, and sucked my cock.

"Fuck, that feels amazing," I said. "You're good at this."

"That's what experience gets you. You'll learn a lot when you go off to college," she said with a smile before going back down on it. She placed her hands on my thighs and dropped down as far as she could go, about three-quarters of the way down, then came back up for air, letting a long string of saliva drip from my mouth to my cock. "You're so fucking big, girls are gonna love you."

"You're just saying that."

"No, I'm really not," she said with a laugh. "I'm tiny. This would destroy me."

"Wanna find out?"

She gave me a playful angry glare. "I told you, I don't fuck at parties. Only skanks do that."

"Not even one time?"

"I'm more likely to walk out that door and make you finish alone," she said. "Your choice." With that, she held her tongue just fractions of an inch from the head of my cock, awaiting my response.

"I'm happy where I'm at," I said.

"Good boy," she responded with a smile, then got back to work. She licked my shaft top to bottom, then back up again before putting her mouth back around the head and sucking it while flicking the tip with her tongue.

"I'm getting close," I warned her.

She lifted her head and stated matter-of-factly, "not in my mouth." She started stroking my cock, aiming it at my stomach.

"Can I cum on you instead?" I asked.

She thought about it for a moment, then said, "fine, you can cum on my tits.

"I was thinking your face."

"Hmmmm..." she thought with her lips scrunched tightly to the side. "Fine, but just because I want to raise the bar for all the girls you're gonna meet in college."

We climbed off the bed and she knelt in front of me. She put her hand and mouth back around my cock and sucked me until I tapped her on the head and told her I was about to cum. She continued stroking me with urgency before letting me take over. She placed her hands up around her forehead and edges of her face to block any stray cumshots from getting in her hair. After a couple quick strokes, I was shooting ropes on her face. She closed her eyes tightly shut as a glob of cum came to a rest on her eyelid. My cum draped over her lips and nose, some even shooting up and landing on her hand barricade. As my orgasm came to a close, the last little bits dribbled down onto her tits.

"Okay, now grab me my towel," she said, eyes still shut but with a growing smile. I grabbed the towel so she could rub the cum off her eyelids and the rest of her face. "I'll admit, there is something very hot about being cummed on. Especially by a young stud like you with lots of it to go around."

She started putting her top back on, but I stopped her.

"Did you want me to return the favor?"

She smiled. "You're sweet, but no. That was a lot of fun as it was, but we're gonna start raising eyebrows if we stay away from everyone for too long. You wouldn't want to hear about it from you sister, would you?"

We wrapped ourselves back in our towels and left at separate times. My sister didn't find out about this until many years later when I finally drunkenly admitted it, but by then they hadn't spoken in a long time so she didn't care much. I still think about Shawna from time to time but I'm pretty sure she's married with kids now.
