PPPE-348 Her older sister has big tits and is okay with in-the-vagina sex, and she's seducing me. Yuino Sayama.

My girlfriend insists on using condoms and no internal ejaculation. But her older sister is the complete opposite, no condoms and internal ejaculation is okay! Plus she has huge breasts and a big ass with a glamorous body! How could I resist such temptation? I secretly had her give me oral sex behind my girlfriend's back! I did paizuri next to my sleeping girlfriend! The older sister with strong sexual desires and I, we had unprotected sex many times while hiding from my girlfriend! The combined effect of guilt and taboo made both of us incredibly virile! In the end, she found out so I showed off a massive internal ejaculation in front of her!
