Alex Chance has huge, full, natural breasts, and while some girls would kill to have them, for Alex they've been causing a lot of problems for her back and she's desperate for some relief. She tells her friend over the phone that she's thinking of getting breast reduction surgery, but her step-mom Jelena Jensen overhears her and doesn't want to see her precious step-daughter do something she might regret. Jelena's a nurse and she's seen enough botched boob jobs to know that Alex would be much better off keeping her big busty breasts intact. But as a mom first and foremost, she recognizes that what Alex really needs is some motherly advice about bras and bra sizes, because her back pain is probably from not getting enough support. She grabs a tape measure and offers to help Alex find the right bra for her needs.Jelena takes Alex's breast measurements while Alex tries on some different bras to see how they fit. Alex lets Jelena know how much she appreciates her help with these kinds of womanly matters -- her real mom was never there for her like Jelena is -- and her step-mom takes the opportunity to give Alex a gentle stroke of her hand on Alex's breast to let her step-daughter know just how much she appreciates her as well. Alex gets a little uncomfortable, since she's never had another girl touch her boobs before, but Jelena assures her that as a nurse, she does this all the time. It's basically like giving a breast exam!As Jelena gives Alex's supple natural breasts a loving squeeze, both can feel the moment coming where they're about to do something they never thought they'd do together. Alex doesn't know if they should, but when Jelena tells her it's okay to want it, Alex resigns to do whatever her mommy thinks is best. Jelena leads her obedient daughter through her first lesbian experience, stroking those huge tits tenderly and sucking on her perky nipples. Finally it's time for mommy to get a taste of her daughter's tight pussy, and Alex finds out just how much about the female anatomy her nurse mom really knows!
