[MF] – fucking my sister’s best friend with my family asleep upstairs

I first met Heather at a house party my freshman year of college, her junior year. She and my sister, Kristen, had joined the same club their freshman year and were inseparable from that point on. Our first meeting was relatively uneventful but it gave me a good idea about the type of person Heather was. She was flirty but in a way that she made it clear it was nothing more than fun banter to her. Certainly, if she had any attraction to me any time we saw each other over the next year, she didn’t show it.

For those that like visuals, Heather was short. If I had to guess, she was under 5’2″. Maybe 115-120 lbs. While she wasn’t toned, everything was perky and fit her just right. Tits that were the perfect handful and a bubbly ass to boot. She definitely tanned year round considering sun was is short supply during the fall and winter months where we went to college. Brunette hair that went down to her shoulders. For you ladies reading, I have a post on ladybonersgw that you can find in my profile.

The following summer, Kristen and I were invited to a distant relatives wedding. We we not very close with this part of the family but our parents forced us to go. We both received a plus one so we made the most of it. Kristen invite my friend Chris as her “date” and I invited Heather as my “date.”

Heather wore a strapless navy blue dress that showed just the slightest bit of cleavage. The length ended right around her mid thigh. She had on tan/beige color heels that propped her up to about my chest. I had no expectations of fucking her (or really anyone else) that night so at a minimum I knew it would be something I could store in my memory bank for later use.

For the entire night, the four of us stayed at our table talking with each other. The more Heather drank, the more her flirty side began coming out. Several times, Heather made comments to me about how surprised she was that I was single which my sister promptly stopped with a quick “ew that’s my brother”. After the third or fourth comment, I began to realize the night may end up differently than I first thought.

Several hours and drinks later, we got back to our house. My parents headed straight to bed. Kristen decided she wanted to go lay down in her room as well. She turned to Heather and asked her if she was coming. Without hesitation, Heather looked to Chris and myself asking if we were going to stay up for a while. We looked at each other and answered that we were going to watch TV for a bit, probably grab a beer or two as well. Heather turned to my sister telling her “I’ll stay up for a bit with them then head to your room.” With that, my sister disappeared upstairs to her room.

Our living room was set up with a loveseat for two people on one side of the room and a longer couch on the other side. I sat down on the love seat. To my surprise, Heather sat down right next to me leaving maybe an inch or two between us. Chris laid down on the couch. Heather, still in her dress, twisted her body to the side and grabbed the blanket behind us. In doing so, her bare thigh grazed against my leg. When she didn’t move it away, I glanced over to her looking right back at me with a big smile on my face. “You don’t mind if I put this blanket over you too, do you?” she asked me, still staring intently back at me. “Nope” was the best that I could muster for a response.

Heather then immediately grabbed my hand under the blanket and interlocked her fingers with mine. I was a bit thrown by her direct approach but I couldn’t deny that it was unbelievably hot. I squeezed her hand while looking over at Chris to see if he was paying any attention to what was going on. It was obvious that he was too busy with whatever was on TV to know or care about what was happening. I look back to Heather who was now also watching the TV or at least that’s what she wanted Chris to think. She then let go of my hand and slid it over my cock. If I wasn’t already rock hard from all the thoughts racing in my head, her hand would have taken care of that. Slowly, she stroked my cock over my pants, still staring directly at the screen. Considering my friend was just 10 feet away, I remained motionless, the subtle movement of the blanket over my crotch the only hint that something more was happening.

After several minutes, Chris got up to go to the bathroom. The moment he left the room, Heather threw the blanket off us, hiked up her dress and straddled me. We began making out with a sense of urgency I had never experienced before or since. Her tongue played with mine as she ground her pussy on my cock through her fabric of her thong and my suit pants. I gripped her thighs and pushed her down on me making sure she felt how hard I was. As soon as she heard the toilet flush, she pulled her lips away from mine and leaned in to my ear. “You need to tell Chris to go to bed so I can fuck you.” Before Chris knew anything had happened, Heather got off me and put the blanket back to how it was like nothing had happened.

The second Chris got back to the couch, I looked over in his direction. “Chris, why don’t you go to bed, you look like you’re pretty tired.” Clearly not realizing what was going on, he just shrugged his shoulders and gave me an “I’m fine.” Knowing he didn’t get the hint, I tried again, with a little more urgency and anger in my tone “Chris, seriously, why don’t you head up to my room, you can have my bed. I’ll be up shortly.” He would later tell me that he still didn’t understand why I was so adamant that he go to bed, but the look in my eyes was enough for him to know he needed to get out of there.

Chris got up and before we could hear his feet hit the second step, Heather pulled down the top to her dress and slid off the couch onto her knees in front of me. As I began unbutton my dress shirt, she yanked my pants down to my ankles gripping my cock firmly in her hand. She wasted no time getting my cock in her mouth as I sat there in awe of how quickly this was happening. Her tongue circled the head of my cock in much the same way she kissed me moments earlier. Seconds later she pushed her way down my entire shaft, my cock disappearing completely in her mouth. She continued this route for about 4-5 minutes before I grabbed a fistful of hair and pulled her off my cock.

“Now I need to fuck you” I told her as she rose to her feet. I did the same, stepping out of my pants that were still around my ankles. I got behind her and put my hands on her waist motioning for her to put her knees on the loveseat and lean over the front of it. She got the hint and did so while hiking up her dress. I placed myself behind her giving my cock a few strokes with one hand while pulling her thong down to her knees with the other. I entered her forcefully which prompted a loud moan. I gave her several hard thrusts which caused her to moan several more times just as loud. I leaned forward and whispered “you need to be quiet or my entire family is going to know what were doing.”

Instead of getting quieter, Heather buried her face in the couch and continued. Her muffled moans were turning me on so much that the more she moaned, the harder I found myself fucking her. The audible sound of my cock and balls slapping her ass after every thrust was now a new worry of mine. That concern didn’t long though. Heather pulled her face away from the couch to tell me that she needed to ride my dick. I gave her a few more thrusts and pulled out and sat back down in the same spot I was minutes earlier. “Don’t you want to take your dress off?” I asked her admiring her tits as she began to hike up her dress again. Heather gave me no response, only a smile an a shake of her head before straddling me and guiding my cock back inside her.

I quickly figured out that this was her favorite position. She got into a slow, methodical rhythm bouncing herself up and down my shaft. Her head flung back leaving her tits just inches from my face. I leaned in and began flicking my tongue over each nipple. She let out a low “fuuucccckkkkk” in an obvious way to tell me to not stop. “Keep playing with my tits. You’re going to make me cum” Heather demanded. I did as I was told. Within seconds I could feel her pussy tense up around my cock. The sensation caused me to thrust upwards in sync with her bounces. I could feel myself getting close as well and told her I was almost there. She immediately got off me and dropped back to her knees where she started. She put one hand around my cock and began stroking me. Her other hand playing with her own nipples. I started moaning my own fucks letting her know I was almost there. “Cum on my tits” was her response prompting me to lean forward on the edge of the couch. After several more strokes, I shot rope after rope of cum over each of Heather’s tits. The sight of my cum on her tits brought a smile to her face.

We cleaned up and went to bed. Despite all the noise that I was certain someone would hear, it wasn’t until years later that my sister found out that we fucked.
