A married woman or girlfriend JD tries out masturbating with her boyfriend's erect penis, saying "It's not cheating if it's just rubbing..." They both enjoy the sensation of their genitals grinding together without actually having sex. As she gets more turned on by the friction, she experiences her first ever orgasm from anal stimulation alone! Her sensitive clitoris can't handle all this pleasure, leading to multiple climaxes even though they're just wearing underwear. Eventually, they continue with the rubbing until cum and pre-cum mix together, causing him to unintentionally insert his cock inside her tight pussy! He gives her a creampie filled with hot cum, pushing them both past their limits!
