[MF] I (24f) once let my sister’s boyfriend watch me change and later caught him jerking off to me on his phone

Last summer I went away for a weekend with my sister, her boyfriend, my step brother and his girlfriend, me and a few friends. My boyfriend was not able to join us. We rented a beach house and it was honestly a really really great time. I had so much more fun than I thought I would.

Anyway, I’m indifferent towards my sister, but she kind of hates me. I’m pretty sure it’s because I’m better looking and have my life together lol. Her boyfriend was great though. He was cute, smart, funny, and too good for her lol

So when I saw him outside my bedroom window, watching me change into my bikini, I pretended not to notice. I’ve caught him checking me out before, and I love being watched, so I didn’t mind him watching me. I’m pretty sure it was an accident since the path to the beach goes right past that window, so it wasn’t like he was trying to spy on me.

When I noticed him I was in my bra and shorts. So I slowed down and gave him a little show. Slowly pulling my shorts off, bending over with my ass towards the window, stuff like that. I even stood in front of my mirror looking at myself naked and even touched myself a little. I put my bikini on slowly, and posed a few times in the mirror before leaving my room for the beach. The whole experience made me horny as fuck, but I couldn’t really do anything about it.

Later that night I came out of my room for a drink. The whole house was asleep after a night of drinking, but there he was. He was on the couch, he had headphones in and he was jerking off. I figured he was watching porn and I kinda got curious so I peaked from behind him. It was a picture of me in my bikini that I posted earlier to my socials. Wow

Honestly it was fucking hot. I knew he checked me out, but I had no idea he was that into me. If I was single I would’ve fucked him right there, especially since he had a gorgeous cock. Instead I watched him jerk off for a few minutes before heading back to my room and masturbated.

Do a lot of guys jerk off to their girlfriend’s sisters? Lol

And no. You can’t see the picture. Or have my socials lol
