IENFH-034 - My Little Sister Said 'Just Rubbing,' But I Couldn't Stop and Fucked Her Raw

Caught jerking off to my sleeping little sister with her panties exposed. She calls me a pervert but takes pity on me, starting with a BJ. When I still can't finish, she says, 'I can't let you put it in, but rubbing is fine.' But we both get too aroused, and I just can't stop myself from going all the way in!
