I recently went to the house of a girlfriend I just started dating, and she introduced me to her sister… she was so well-endowed (G-cup) that it was hard to believe they were sisters. Her personality, face, breasts, sex... everything about her was superior to my girlfriend's. She was such a good girl that I couldn't hold back and made a move on her... what?! She didn't resist? Since she was so weak to being pushed and couldn't say no, we ended up crossing the line and had sex. 'No... my sister is right here...' I couldn't resist her sister's huge breasts peeking out from her school uniform... I sneaked away from my girlfriend's gaze and pounded her untouched sister with my dick! I enjoyed the taboo feeling as I turned her young, fragrant student pussy into an orgasm swamp... I did whatever I wanted to her honest and sensitive sister pussy, making her cum over and over again!
