Mijn stiefzus die alleen woonde, kwam plotseling terug naar mijn ouders huis! Ze is altijd naakt zonder me op te merken.

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.
