You surprise step-mommy by coming back home from university earlier than you were meant to. She's been so lonely since you left, but wants to hear all about the fun you've been getting up to. You sound like quite the ladies' man, but step-mommy used to have fun back when she was younger. She tells a naughty story about her uni-days, which starts to turn you both on. You need to blow off some steam, and step-mommy needs some attention.
She rubs her pussy, before you bend her over the table and fuck her hard. She sucks your cock before riding you cowgirl, cumming on your cock. Finally, you fuck her on the floor, missionary, and fill up her pussy with your load. [Implied video, no toys used. Very dialogue-based, slow build fetish video]
