YLWN-267 - Sweet moans from the next room!? I couldn't help but ravish my little sister in the middle of masturbating... 4 hours

Sweet moans coming from the next room... I peeked in and saw my cute little sister masturbating in a trance!? Watching her clumsily touch herself and reach for climax, I couldn't hold back my excitement. I quietly crept up behind my defenseless sister while she was in the middle of it.
