I went to a friend's house to hang out, and his sister came out after taking a bath, wearing only a bath towel!! Whether she knew it or not that I had nowhere to look, she was showing off her cleavage and even her mons pubis, making me fully erect!! However, the temptation continued, pushing my rationality to its limit… I can't lay a hand on her because she's my friend's sister, but I can't take it anymore!!
