Her sister seduces me with big breasts and creampie OK

My girlfriend is a condom! I'll never let you do it raw! I've been dating for a long time, but I still can't do it raw... I was hungry for raw sex, so my girlfriend's lady showed me her big breasts and seduced me, saying that she could cum inside me! Even though I like her, I can't stand it when my older sister pushes her against me! I was covered in the older sister's squirting, but my erection was unsatisfied with the thrill and guilt! In the end, she found out, but it's OK because you can have sex with the older sister raw!
