Time Stop Universe: The Lab

I've been slaving away in my lab for months, chasing the ultimate fantasy: the power to stop time. My stepsister Riley thinks it's all bullshit. "You're never gonna make that happen, Rion," she sneers, rolling her eyes as she lounges nearby in her tight little shorts and tank top that hugs her perky tits. But then—click! I hit the button on my device, and there she is, frozen solid like a perfect statue, her lips parted mid-sentence, eyes wide, body utterly still. Click! She's back, gasping, cheeks flushing. "What the fuck was that?" she whispers, but I see the spark in her eyes—she's intrigued. Turned on, even. "Do it again," she breathes. Click! Frozen once more. This time, I step closer, my hands roaming her immobilized body. I squeeze her firm ass, slide my fingers under her top to pinch her hardening nipples, then yank down her shorts to expose her shaved pussy. She's helpless, a sexy doll for me to play with. Click! She stumbles forward, panting, thighs slick. "Oh god, Rion... that felt so intense. Don't stop." We keep going—click, pause, play—me fingering her frozen slit until it's gushing, spreading her lips wide, teasing her clit while she's a statue. Repeat. Her pussy's dripping wet now, juices trailing down her legs when I release her each time. She's begging, grinding against my hand. "I need your cock, bro. Fuck me like you've always wanted." Finally, I can't hold back. I've dreamed of pounding Riley's tight stepsister cunt forever. I strip her bare, bend her frozen form over the lab table—click!—and slam my throbbing dick balls-deep into her soaked hole. She's mine to ravage, time stopped or not.
