Family Fappenstance: Beatin' to my Sister

"Hey! Don't jack off with my underwear!" "Fine, then can we jack off with you?" "Whaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaat" In an 8-person family with no mother in sight, it's up to the big sister to take care of the men. But they've all got a bit of a problem expressing their sexual sides in a healthy way... So hey, why not make that another of big sister's jobs, too? It was only a little while ago that she was in the bath with all of them, right? It's not weird if she helps out just a little. Okay, it's a little weird, but if it's for the family, she'll do it... even if it means losing her virginity!
