"You play better or worse when you're aroused?" asked your stepmom.  Soon after that, she climbs behind your back on the sofa and starts fiddling with your underwear. She first slips her hand inside your panties, starting to feel your big cock. It's soft now, but it will get hard soon! She pulls it out of your boxers and starts to massage the tip. It's been a while since you and your step-mom spent some time together alone at home!  She gives you reach around handjob. She's naked behind you, you can feel her breast pressing on your back and you can see her feet resting on your knees.  You can tell that she's having fun, she is giving you an edging session that's making it difficult to focus on your game.  You hope that you will get something more this time, but in the end, she denies you again!  TL:DR Handjob from behind on the sofa while the man plays computer games.  Orgasm control. Teasing and denial.
