Blindfolded girl fucks another guy without knowing she's cheating

A guy wants to help his buddy lose his virginity but can't find a girl, so the clever ladies' man offers his own girlfriend for an hour despite the betrayal. He comes home, gets his girl hot, and suggests fucking with a blindfold. The trusting babe, suspecting nothing, ties the mask around her eyes, strips off her panties, and gets ready for pleasure. His friend sneaks in and immediately starts eating her pussy, then slides his cock in and fucks the young beauty hard. She begins to sense something's wrong and removes the blindfold, but getting fucked by this other guy feels so good she doesn't resist—she just keeps cumming until her belly is covered in his load.
