My girlfriend swallows my friend's cock and lets him fuck her mouth really hard

As the scene opens, we see Josh and his girlfriend, Sarah, in bed. Josh's friend, Mark, joins them, kissing Sarah passionately as Josh watches. The excitement between them is palpable. Mark undoes Sarah's shirt, exposing her perky breasts, before taking one into his mouth, drawing circles around her nipple with his tongue. Meanwhile, Josh rubs his clothed erection against Sarah's ass through their clothing. Mark pulls back, stroking the length of his cock as he watches it glide over Sarah's naked skin. He slowly pushes inside her mouth, relishing her eager sucking sounds. Their eyes lock as he begins to fuck her face harder, faster. The camera zooms in on Sarah's lips stretching around Mark's shaft. Finally, he pulls out and covers her face in cum, which she eagerly l icingly consumes before kissing him passionately, their bodies entwined in a post-coital bliss.
