Her younger sister, who I thought was innocent and naive about sexual matters, suddenly transformed into a nymphomaniac! She showed me her underwear, begged for kisses, and took advantage of my lack of awareness as a woman to get me fully erect!! When I found out we hadn't done it raw before... she sat on my lap and took things into her own hands with a raw encounter!! Unable to resist the innocent pleasure of her bouncing around, I ended up cumming inside her multiple times!
