[M] My friend’s sister is very hot and sexy. Once I caught her having sex with her boyfriend when we all went to spend a vacation together at a cottage.

She’s blonde with amazing figure. I can’t stop myself staring at her. Once we all went to spend a vacation at a cottage. I heard sounds at night and went downstairs and caught her having sex with her boyfriend at night in a room. I had to go outside and watch from the window. It was exciting though.
