Min styvsyster som bodde ensam kom plötsligt tillbaka till mina föräldrars hus! Hon är alltid naken utan att märkte mig.

The sight of my sister in the nude was too much stimulation for me as a virgin, and of course I got a full erection! As I started to make fun of her, she took pity on me and asked me if I wanted to fuck her. I was so excited that I couldn't stand my desire.
