You are hanging out at home on a rare day off when step-Mom walks by and praises you for how hard you've been working, supporting the family during the pandemic. step-Mom encourages you to enjoy yourself and maybe "find some girl to get off to," before heading to the bath to relax before dinner. After just a few minutes, she comes out wearing nothing but a towel, announcing that she decided to take a quick shower instead, and when she sees you openly jerking off in the living room she lets the towel drop in surprise. step-Mom can't believe how HUGE your cock is! You need both hands to jerk it, and it looks like you could use a third! She pantomimes its size, encouraging you to keep stroking. She wants to see how much cum a huge cock like that makes! She describes all the things she would do to a massive cock like that, and when you're not getting your load out fast enough she decides to help you out, telling you to lay down on the ground so she can mount you. Squatting on top of your oversized member, step-Mom rides you while gushing over your size but warning you that you can't cum inside her pussy! When you get close, step-Mom gets off and tells you to blow your load all over her face, tits, and abs, confessing that when you were fucking her she was really tempted to let you just cum inside her! You start to cum and it gets everywhere, absolutely covering your step-Mom as she exclaims in delight how huge your load is. No toys are used, everything is implied. This was a custom request but no names are used.
