My sister and I distribute a bedroom wall, and on the first night our parents were away, she invited her boyfriend. I heard sex sounds coming from her side. At first I was weirded out, but then I got curious and pressed my ear to the wall. I could hear everything: her choking on his cock, her moaning while he ate her out, then fucking, rocking the bed. I was getting so turned on.

I touched myself while I listened, imagining what it would be like to be in bed with them. My sister was having the time of her life, and I was right there with her, enjoying every minute of it. It was the best experience I’ve ever had.

I was in my pajamas, about to go to bed when I heard my sister and her boyfriend in the next room. They were having sex, and I couldn’t help but listen. I was so turned on, and I masturbated while listening to them. I’ve been doing this for four nights now. I haven’t said anything, because I don’t want to weird them out. But hearing them has built me so horny. Last night, I ‘went to bed early’ in hopes that they would have sex sooner. And they did! I never wondered of my sister as a sexual being before, but she sounds like a porn star when she’s having sex. And her boyfriend is such a nice guy, but it sounds like he really knows how to please her. I can not stop thinking about them, and I want to join them. But I don’t want to weird them out, especially my sister.

But ugh. The sounds! I’m trying to study but all I can think about is how my sister is getting fucked hard right now. And how I’m so horny and frustrated. I need to get laid. Or maybe just spy on them again tonight…
