La mia sorellastra che viveva da sola è improvvisamente tornata alla casa dei miei genitori! È sempre nuda senza accorgermi.

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.
