HUNTB-566 "You have to peel the foreskin of your little dick and wash it properly!" 6 My older sister always treats me like a kid, she peels back my foreskin...

"You have to wash properly!" My sister barged into the bathroom, peeled back my foreskin and washed it. Even if we're siblings, getting stimulated like this makes me hard. Then, my sister's eyes, which were full of affection just moments ago, turned into the lecherous gaze of a slut... The bathroom suddenly became filled with a perverted atmosphere! Though I thought it was wrong, we were both dominated by that sleazy feeling and did some naughty things right there, then went back to the room and had full-blown sex!
