I’m Tired after Work, my Stepsister Tired after School. Relaxing until the Parents Returned

After a long day at work, you're exhausted and just want to unwind. You're ready to sink into the couch and catch up on some Netflix, when suddenly, your stepsister walks in. She's just as worn out from school, but with a different kind of exhaustion. She's been thinking about you all day, and it's not just because of the cute pink nipples peeking through her school uniform. She's got a burning desire, and you know exactly how to quench it. The two of you decide to relax, just the two of you, before the parents return. You're both too tired to go down the usual avenues, but that's what makes this even hotter. It's a step fantasy come true. She straddles you, her big, round ass grinding against you, her small hands fumbling with your zipper. You can feel her heat, her wetness, even through her stockings. She's ready, and so are you. As she takes you in, her mouth and lips work magic, her dirty talk driving you wild. You can't help but groan as she takes you deep, her head bobbing up and down, her big tits bouncing with each movement. You feel her tongue swirling around you, her throat relaxing to take you in even deeper. She's a natural, and you're loving every second of it. You're both getting more and more turned on, your bodies moving in sync, your breaths getting heavier. It's a sloppy blowjob, but it's your sloppy blowjob, and it's perfect. As she feels you getting closer, she looks up at you with those big, innocent eyes, and you know you're about to explode. You come, hard and fast, your cum coating her lips and chin. She swallows every last drop, her eyes never leaving yours. It's a moment of pure, raw sexual pleasure, just the two of you, relaxing, and it's everything you've ever dreamed of.
