[MF] The time I gave a handjob to my sister’s boyfriend

Growing up, my parents used to take my younger sister and I to a lake house every summer that was owned by some of their good friends. It was always a great trip filled with tubing, water skiing, wakeboarding and grilling. When my sister and I got older, my parents started letting us invite friends and eventually boys.

Most of the space in the house was upstairs which was a kitchen, living room, master bedroom and another bedroom with two beds. The downstairs was a garage, storage and another bedroom with 2 sets of bunk beds in it.

​

My junior year of college, my sister had just graduated from high school and she had just started dating this guy from high school that was going to be starting at the same college as her in the fall, his name was Eric. My parents liked Eric, and we had known him and his parents for years because he’d been going to school with my sister since elementary school. So they invited him to come with us on our trip which lasted 4 days. He was staying downstairs and my sister and I were sleeping upstairs. I think my dad liked when we had guy friends at the lake because he was always around so many women, and he also had more fun driving the boat with guys tubing or skiing because he could be adventurous.

​

As we got older there was always a lot of sexual frustration at the lake when we brought boys. Lots of hormones, tans, bathing suits and living in close quarters. This trip was no different, and my sister and Eric definitely were trying to find moments of alone time whenever possible, which was hard to do. I caught them making out a couple of times, when our parents were busy making food, cleaning or showering, but I don’t think they went any farther because our parents were pretty good about keeping close watch on us with boys.

​

I had caught Eric staring at me in my bathing suit a few times on the boat, and I could tell he was attracted to me. I don’t have huge boobs but I can fill out a bathing suit top better than my sister, and he definitely took notice.

​

By the time the last afternoon rolled around, there was a lot of sexual energy between Eric and my sister when my parents weren’t looking, because I could tell they wanted to go fuck like rabbits downstairs. I could feel all the pent up sexual frustration and something about it made me sexually frustrated too.

​

So, we got done with our last boat trip at about 4:30 in the afternoon. My dad had to put the boat up on this lift and clean it, and the rest of us went back up to the house to clean -up while my mom started prepping for dinner. My sister called the shower first (the only shower was upstairs in the master bedroom), so while she was showering I snuck downstairs and walked into the Eric’s room.

​

When I walked in he was getting his clothes and toiletries together because he was next to shower. I went and sat on the side of his bed next to him and asked him “You haven’t been messing around with my sister with my parents around on this trip… have you?” He said no, he didn’t want to risk getting in trouble with my parents. I then said “well it must be hard for you to get through this trip staring at my sister and I in bathing suits all day.” while I untied the top knot of my top and pulled it down exposing my breasts and said ” and I bet you’ve been thinking about what these look like.”

​

He started to make a move to reach for them, but I stopped him and said “no, you can look but you can’t touch” I then pushed his chest back on to the bed and untied his bathing suit and pulled out his cock which was super hard. I started to stroke it slowly and I asked him if he’d ever fantasized about me and my sister, which he obviously said yes. I started stroking him faster and kept talking dirty to him about being this his girlfriend’s big sister and after about 2 minutes he was shooting cum all over himself. When he was done, I got up and wiped my hand off on a beach towel, tied up my top and left. I didn’t talk to him the rest of the trip or on the ride home the next day.

He and my sister broke up some time after that before school started and I’ve never seen him again.
