I cheated on my girlfriend for the first time... As soon as I saw her, my sister's breasts were burned into my mind! Even through her clothes, their size and softness were unmistakable... Wait, are they naked underneath? My instincts took over, and I couldn't resist seducing her. Her perfect fit pussy was so tight that even the condom disappeared quickly! Fuck her harder! I pounded her relentlessly without mercy! And before I knew it, I had gone through an entire box of them...
