Teen Lilly Ford is busily humping her pillow, when step mother Eva Notty hears strange noises coming from her bedroom and opens her door. Lilly is extremely embarrassed about getting caught, but Eva Notty is understanding and supportive. Lilly explains that all the girls are talking about their first orgasms, and even though she gets close, she can't quite make it all the way. Eva suggests Lilly try humping her instead. Lilly isn't sure what her dad would say about that, but Eva assures her if they leave their panties on, it doesn't count. Lilly's on the verge of cumming so she's rather obliging. Eva begins their hump session by teaching Lilly how to kiss. She instructs her to start slow, and not be eager. When Eva tries to look at Lilly's boobs, Lilly gets shy about how undeveloped her tits are compared the MILF's monster boobs. Eva removes her robe and bra, and encourages the teen to slip out of her top and nurse her nipples like a suckling babe. Lilly loves having her step mother's tits in her face. She asks her a lot of questions about what feels good because she's only eighteen and hasn't done this before. Eva teaches her how to get warmed up for sex by fondling and caressing her boobs. That stimulates the clit to get very wet and tingly. Next Eva instructs Lilly to lie down on the bed and hump her like she humps her pillow. Eva touches Lilly over her panties and exclaims that her pussy is so wet! Lilly breathes heavily as the MILF rides her crotch over her panties. Eva teaches her it's best not to cum right away, and slowing down her movements will allow her to control her orgasm. But when Lilly still hasn't cum Eva suggests they take off their panties. Lilly's nervous about her dad walking in while they hump each other with no panties, but Eva brushes off her concerns. Lilly is very impressionable, so close to cumming. She feels a real difference with direct contact, and she begs her mom not to stop. The lesbian MILF grinds the little teen's pussy really fast. Lilly tries to explain how she's feeling as she experiences her first orgasm ever tribbing with her mom! While Lilly is still tingling from cumming for the first time, Eva demonstrates on the teen's pussy how to eat it properly and lick it with a flat tongue. Lilly warns her step mother, she's going to cum again in her mouth. Then Lilly offers to reciprocate. Eva instructs Lilly to straddle her face and bury her head in her pussy at the same time. Lilly has trouble concentrating during the 69 and cums again. Each orgasm is more intense than the last, she notices with wonderment. The lesbians pleasure each other's wet pussies with their roaming fingers and tongues, and then step mommy Eva rides Lilly's sweet face till her pussy explodes!
