The girls' eyes widen as their black neighbor's thick, long cock springs free. They've seen plenty of dicks, but never one like this. They tentatively touch it, feeling its heat and weight. He guides them, teaching them how to suck and stroke a black cock. They take turns, their pale hands contrasting with his dark skin. He fingers them, making them squirm and moan. Then, he lies down, and they straddle him, one at a time, feeling that massive cock stretch their tight pussies. They ride him, their bodies glistening with sweat, their moans filling the room. It's a new world for them, and they're loving every minute of it.
