It’s her first day on the job, but she’s such a slut, she already invited her boyfriend over so he can feel her tender tits while she wraps them around his throbbing member and gives him a hot tit job! The hot teen babe loves feeling his cock get big and hard between her big succulent tits, and she strokes and sucks his member with a dirty look on her slutty face. Teens are so busy getting it on, they don’t manage to react in time when they hear the front door opening up and seconds later, the hot mature owner of the house walks in on them, wearing a sexy blouse and skirt that shows off her long, beautiful legs. She is quite shocked to find her babysitter sucking dick on the job and her uninvited boyfriend. As she berates them for their naughty behavior, she can’t help notice that the boyfriend’s cock erection doesn’t subdue a single inch; matter of fact, it just seems even bigger, thicker and harder! The MILF pushes the babysitters face against his crotch and feels her panties getting wet as she deepthroats her boyfriend’s massive member. She joins her, licking his rod along with the babysitter and tasting her lips and tongue. She spreads the babysitter’s legs and rubs her cunt as the boyfriend penetrates her so she can watch the teen slut squirt.

The dirty MILF slut is a natural born squirter too, and she’s eager to show them her impressive squirting abilities! The boyfriend rubs his cock all over the mature slut’s pussy as she squirts, squirting juices all over his dick! The experienced mature woman fucks so much better than his teen girlfriend! The real threesome begins after the babysitter grabs a video camera and films her boyfriend banging the hot mature woman and captures her squirting orgasms. Probably so the MILF can study them later and learn all her incredible gushing techniques! Her squirt juices splash and splatter all over his cock, his chest and her inner thighs, it looks so fucking sexy and hot! She rides his dick and squirts again and again, then she gives him foot job, jerking the guy off between the soles, and finally my favorite scene when the hot and crazy MILF rubs her wet twat, squirting over the teen girlfriend who sucks bf’s dick. She can’t stop squirting! She grabs his dick and shoves it in her wet twat, then in his gf’s mouth, again in her squirting twat and back into his gf’s mouth… It’s something absolutely amazing!
