When I went to visit my girlfriend's house, who I've just started dating, she introduced me to her younger sister...I wonder if they're really sisters? Her personality, face, boobs (G cup), sex...everything about her younger sister is better than hers, she's just too good...I couldn't hold back and attacked her! ...What! She doesn't resist!? She's a really good girl who can't say no to pressure, so I just crossed the line and had sex with her. "No...my sister is nearby..." I couldn't resist the big tits of my younger sister that I could see through her uniform...I stole a glance from her and thrust my dick into her undeveloped younger sister! I felt a sense of immorality as I made the young and mellow student pussy fall into the swamp of instant orgasms...I did whatever I wanted to my obedient and sensitive younger sister pussy and made her cum over and over again!
