She traces the outline of his cock, feeling it pulse with desire. He groans softly, his hands finding her hips, pulling her closer. Their lips meet in a hungry, forbidden kiss, tongues dancing as they explore each other's mouths. She grinds against him, feeling the wetness between her legs soaking her panties. He responds, his hands roaming, cupping her breasts, squeezing her ass, until they're lost in their own world, oblivious to the reality outside their hidden paradise.
