Your silver-haired mature MILF step-mom Jamie was doing her usual cleaning rounds when she happened on something that shocked her : your panty stash, and they're HER panties! Trying to be understanding and non-judgmental, she tries talking you through why you're hoarding her panties, but admits to feeling horny and naughty about the thought, and lifts her dress for some upskirt flashes of her panties before sliding them off and letting you add them to your collection. Not content to just give you a new item for your collection, she wants to share the experience of your fantasy and strips herself naked for you and joins you on the couch, where she warms you up by stroking your cock. Once you're hard and horny as her, she bends over against the back door and lets you fuck her hard from behind, then returns to the couch to ride your cock hard, finally letting you spread her wide and fuck her hard until you shoot your big creampie load in her shaved smooth mature pussy
