Your mother-in-law is staying with you after her relationship fails yet again. You avoid her as much as possible by working in your home office, but she’s cornered you in the living room this afternoon. Your wife is away on business so you know your mother-in-law is looking for someone to bother. She mentions that you are SUCH a good man, too good for her daughter maybe. You take good care of everyone but does anyone take care of you? You try to ignore her but she’s playing with her cleavage, eventually revealing her big soft tits. You're shocked and tell her to stop despite the throbbing hard on in your shorts. She rubs your dick through your pants and convinces you to pull it out for her, it'll be your little secret. She starts off pleasing you with her mouth, before climbing on top and putting those soft tits in your face as she rides. Once she cums it's your turn, and she lays back to let you get on top. You pump until you blow a massive load in your wife's mom!
