My boyfriends annoying roommate

I (19F) uncomfortably in my seat as I heard my boyfriend Mark get into the shower in the bathroom upstairs. Leo, (23M) my boyfriend's roommate had walked over and sat down right next to me on our two-person sofa. Leo had this knack for doing small things that got under my skin. Leo is a fun, outgoing person that easily puts a smile on others and has this radiating confidence about him that makes people like him.

"Hey Sarah," he said with a slight grin. "Looks like you two really went hard today."

Mark and I run a fitness coaching business and we just finished a boot camp in the square across the street. Today's session had been particularly intense, a total body workout that had me completely drained.

"We were," I admitted, leaning my head back. "I’m wiped out. And starving. I just hope Mark doesn’t spend an hour in there so we can finally grab some food."

"You know his routine," Leo grinned. "He treats that shower like a spa day."

I smiled because I knew he was right. MMark was notoriously slow. Right then, my leg accidentally brushed Leo's and I felt a strange tingling sensation ripple through my body. Ugh, I thought, annoyed. There was plenty of room on the couch; he didn't need to be hovering right over me.

I tried to shift my weight and tuck my legs away from him, but a sharp, stabbing pain flared in the right side of my neck. Leo, who had gone back to looking at reels, noticed my wince immediately.

"Stiff neck?" he asked.

"Think I might have pulled something during the burpee sets" I replied.

"Let me fix that for you" Leo said. "I’ve got the magic touch."

"I'm sure you are," I said skeptically. "But I'm good. We're going to do some yoga later and that'll sort it out."

Leo rolled his eyes. "More exercise? You need to actually decompress for once. Just let me give you a quick rub and you can skip the yoga."

"I'm don't think Mark would like that," I said.

Leo said, grinning, "Well, he's in the shower. What he doesn't see isn't going to cause any trouble."

I stared at him with surprise. Leo was looking directly at me with an intensity I hadn't seen before.. He smiled and scanned his eyes down my body. I was still in my low-cut gym tank and tight spandex shorts, and suddenly I felt incredibly exposed. Wishing I was wearing something a lot less revealing. Leo had never flirted with me so deliberately before and it was throwing me off. He had always been friendly, but I had just chalked that down to his jovial personality.

I knew Leo's flirtiness had made Mark a bit uncomfortable in the past. Mark and I had a great relationship, but it wasn't without its ups and downs. Few days before we had a terrible row over some jealousy Mark had with one of my guy clients and I'm sure Leo, in the other room, had heard every word. Allowing him to touch me felt like playing with fire.

"No, really, I'm fine," I said, my voice firmer than before.

"Common Sarahhh, just give me thirty seconds" Leo pressed on. "If you don't like it, I'll stop. Mark is definitely going to be in there for another 15 minutes." He hadn't stopped smiling and his cocky expression was really starting to annoy me.

Right then, the pain in my neck gave another sharp stab. Would a quick massage really be that bad? It was unlikely we were going to do yoga in this exhausted state and I didn't want to go to sleep like this. I reluctantly agreed to the massage but warned him to keep it short.

"Ok, turn around," Leo said.

I brought my legs up onto the couch, turned to look away from Leo and towards the window, and folded my legs into my lap.

I was not prepared for my body's reaction as Leo's calloused hands gripped my shoulders. I gave a light shudder and felt goosebumps crawl all over my arms, neck, and legs. I heard Leo chuckle. "I'm not going to bite, I promise."

I had to give it to him, he knew exactly what he was doing. His palms worked my shoulder blades while his thumbs dug deep into the tension at the base of my skull. Whether it was the stress of the business or the physical toll of the day, I felt my defenses start to crumble. The relief was almost instant.

"That feels good" I said quietly. Leo said nothing but started to work his way down to my lower back. As he grabbed my hips and started to squeeze, I gave out an audible gasp and was about to protest, but I couldn't bring myself to say a word.

"I can't quite get to all the knots like this," Leo mumbled. "Can I reach under your shirt?"

I nodded, not entirely sure what I was agreeing to. I knew I would be in huge trouble if Mark came out of the shower now. Leo reaching under my shirt and exploring my back had crossed a line. But the feeling of his skin against mine was intoxicating, and I didn't want the sensation to stop.

Leo shifted, spreading his legs so he could pull me back against his chest. My backside pressed into him. My ass lightly brushed his lap and I felt that he was semi hard. I nervously glanced at the bathroom door but could hear the shower still running. Leo's massage had now turned into more of a caress. Without thinking really, I reached back, my hand landing on his thigh, my nails grazing the fabric of his shorts, giving it a light scratch with my fingernails.

That was all that Leo needed. He firmly grabbed my hips and pulled me in even closer. He was now rock hard and pressed firmly up against the upper half of my ass. He reached under the shirt to the front and squeezed my breasts. With his fingers, he started lightly flicking and playing with my nipples. I put my hand in my mouth and bit down on it to stop myself from moaning out loud. I felt guilty and was more turned on than I ever remember being. Here I was, sitting on my boyfriend's couch, getting fondled by his roommate as he showered in the other room.

Leo’s hand slid down, disappearing into my shorts. I was already completely wet from the whole situation. I thought he would finger me, but I was wrong.

"Wow, you're already so wet," Leo whispered softly in my ear. "Let's fuck, quickly." I nodded and Leo motioned me to get up on my knees as he pulled my shorts and panties down my thighs. He pulled down his own shorts, grabbed my hips, and started to slowly sit me down on him, penetrating me as I sat.

Because I hadn't been facing him, I hadn't seen him and didn't know what exactly to expect. When I felt it enter me, I actually grunted out in a mixture of pain and pleasure and for a minute was afraid that Mark would have heard me. He was super thick, much thicker than Mark, and my pussy was not ready to it.

I began to move, bouncing slowly up and down on him. I took turns grinding my ass in a circular motion and letting him pull me up and down. The risk of being caught in Mark’s own home by his own roommate was making my pussy twitch. Leo continued playing with my chest and I was in absolute heaven.

We had probably only been fucking for a few minutes and I heard Mark turn the shower off inside his bathroom. I frantically stood up and pulled my shorts back up. I could not believe I had just fucked Mark's roommate. Leo was looking at me, grinning.

I ran into the bedroom and shut the door, trying to regain my composure. I could not sit out there next to Leo when Mark came out of the shower.

Neither of us came. The massage and fuck probably only went on for fifteen minutes but I was never hornier than at that moment. I rushed to the bathroom when Mark came back, fingered myself till I came, and took a shower. I spent rest of the night fucking Mark pretending it was Leo.

I will write second part if people like this one
