I (20F) had sex with every boyfriend my sister (19F) ever had and I simply love it.
My sister and I never were really that close, we always behaved more like rivals to each other. Even when we were younger we always compared who got the cooler friends, the best gifts and who is better within their sport activities or grades. When I thinking about it, our parents never actually tried to stop this and so it goes on until now.
But with one activity my sister cant hold my pace … fucking each other boyfriends. That’s because I’m the hotter sister, I have a way sexier body, in part thanks to my big tits, that makes her really jealous, in that aspect she will never beat me. So every time my sister is bringing up a new boyfriend, I propose to myself to fuck him and as far as I know, I missed none.
So over the last years I had sex with 5/5 boyfriends I knew from her. I usually become acquainted with them when she takes them home or if we have friends in common I ask them for help to get to know my sister boyfriends. After first get known to her boyfriends, we start normal texting, often they like to hear stories from our rivalry between us. After this, meetings without my sister … meet for a coffee or ice cream … just because I feel “lonely” and “envy” my little sister with her great boyfriend.
After the first meeting, it was always a no-brainer, keep on texting, keep on meeting, show some skin…. and here we go. I don’t rub it on my sister face, that I sleep with them but every time, I hear from my friends that she left her boyfriend because he cheated on her, I am so satisfied I cant describe.
With her latest boyfriend it was the same. She brought him up to our fathers 55th birthday for the first time. My parents were so pleased to meet him and my sister so proud of him, because he is really hot, I have to admit. During the birthday I utilized every opportunity to chat with him and at the end of the party he had my number and I had his. So we started texting and I made up my usual vulnerable sister scam.
After a while we met for lunch when my sister wasn’t in town. I wore a skirt and belly top to turn him on and it worked better than I expected… we didn’t even get home. When I went to the toilet he followed me and we started to kiss each other. We both went into a stall together and he pushed me to sit down on the toilet seat, he unbuckled his pants and I started to give him a blowjob. I even managed to get some lines out like “This is wrong” or “What about my sister?”. Long story short, I let him cum in my mouth because I know my sister don’t like that, she hates the taste, she say that to her boyfriends. I love it … at least when its her boyfriend cumming in my mouth. Since this first time we had sex multiple times and keep cheatting. I can’t wait for her to find out and get new boyfriend.
