When I went to her house to play, I met her big-breasted little sister for the first time. She exposed her chest without any defenses and tried to seduce me, even attempting to steal me from my girlfriend! While cooking, while taking a bath, after she fell asleep... I secretly had sex with her little sister all day long without her noticing! I couldn't maintain my composure with her breasts spilling out in front of me, and I ended up cumming on her cute little sister's face multiple times!
