Hi there,

I just saw your prompt about the swinging parents and would love to give it a try.

I hope you'll forgive my English as I am not a native speaker. Also, I am writting this frome France, so the time difference may be a thing to keep in mind :)

Ok, enough with the talking. here we go.

"It all started a month ago. I remember waking up in the middle of the night, persuaded that my older sister brought a new boyfriend into her bedrooms again. See, her room is next to mine, so last time it happened, I managed to catch a glimpse of her naked body by leaning out of my window. The rush of guilt and excitation that I felt almost made it impossible to get a hard on. But man... you gotta understand. My sister is... well you know what she looks like, right? She's hot. And she's a real slut. And fuck, it was definitely better that the porn I watch on my computer. Anyway. Where was I? Yes, I woke up and I went straight to my window but it wasn't my sister. Her room was dark and the sound was distant. But it was definitely moanings. No doubt about that. For a few minutes, I thought that she was doing it in the bathroom. So I grabbed one of those old condoms they give for free at schools just in case, to be able to wank and cum in the couloir, and I left my room, as quietly as possible. But I quickly realised that it definitely wasn't my sister. The moanings were coming through my parent bedroom's door. I froze as I recognized her voice, man. Please don't judge me. But... well, you saw my mum, right? And I was already hard as a rock... And the curiosity, man... I had to see it. So I got to the door. And I swear it was already slightly opened. So I took a look".
