Swap Sis “I’m petite, I have the tightest pussy! Let me prove it”

She’s a tiny thing, but that mouth is a weapon. “I’m gonna suck your cock so deep, I’ll be tasting your balls,” she promises, eyes gleaming with mischief. Her sister watches, lips parted, as she drops to her knees, tiny fingers fumbling with his belt. He’s already rock hard, throbbing against his jeans. She frees him, and it’s a monster, veiny and thick, the kind of cock that makes her mouth water. She takes him in hand, strokes him a few times, and then her tongue darts out, licking the precum off the tip. It’s salty, musky, and she moans, taking him into her mouth. She’s a champ, deep-throating him like it’s nothing, gagging slightly but pushing through, taking him deeper with each thrust. Her sister can’t take it anymore, she’s on her knees beside her, eager to join in. Two sets of lips, two tongues, fighting over his cock, fighting to be the one to make him explode. It’s a fucking mess, spit dripping down their chins, but they don’t care. They’re in it for the win, in it to prove who’s the best, who can take the most, who can swallow the most cum.

The room is filled with the sound of their slurping, their moaning, their fighting. He’s close, his hips bucking, his hands fisting in their hair. They know it, they can feel it, and they’re ready. They’re going to take every last drop, and they’re going to enjoy it. His cock pulses, and he comes, hard, his cum shooting down their throats. They swallow, greedily, licking and sucking until he’s clean. They pull away, grinning, triumphant. “Told you I had the tightest pussy,” she says, wiping her mouth. “But I also have the best mouth.” Her sister just laughs, knowing she’s been bested. And he? He’s just a lucky son of a bitch, enjoying the aftermath of the best blowjob of his life.
