I went to her place for an overnight date, and there I found a sister who lives with her and has a wonderful smile and huge breasts! For some reason, this incredibly charming sister suddenly started seducing me right in front of my girlfriend, leading to an instant erotic scenario! While I felt guilty towards my girlfriend, that only made it more exciting. I went wild having sex with the sister. My girlfriend insists on using condoms, but the sister is okay with bareback! She's even okay with inside-out ejaculation! There's no way I can resist such a temptation!
