Horny step-mommy's edging JOI with tit tease

You have been expecting the birds and the bees to talk ever since you brought your girlfriend over for dinner, but you didn't really expect it to come from your Step-Mom. To be honest, you feel a bit awkward about it. You have been embarrassed by the way you can't stop staring at her tits recently and were hoping she hadn't noticed. She explains that she knows you've probably already heard all about how to use condoms in sex-ed class, so she's going to teach you something a little different. "It takes a lot longer to satisfy a woman", she explains. "Why don't we try a little practice round, to see how long you can hold off on cumming?" She offers to tease you with her huge soft tits, telling you exactly how to stroke your cock and edging you before finally telling you to cum for her, shooting a huge hot load and emptying your balls.
