I went to her house to play, and I met her big-breasted younger sister for the first time. She exposed her chest without any defenses and tried to seduce me, even attempting to steal me from her sister! While cooking, while taking a bath, after her sister fell asleep… I secretly had sex with her all day long without her knowing! Unable to maintain my sanity with breasts spilling out right in front of me, I ended up cumming on my cute little sister's face multiple times!
