Pink Onesie Butt Flap Fiasco

My teen stepsister and I have this thing going. She lets me fuck her, we keep it quiet. I walk in, flip open that pajama flap on her ass and pound until we both get off. Last night I'm heading in for more, and she’s already on all fours waiting. I pull the flap, slide in — then she spins around and it’s my stepmom Tia Cyrus staring back at me. Dead giveaway I’d been played. Tia says she found out and now I’m hers. Stepsister’s done, Mom’s taking over. I’m balls-deep before I can argue. She’s soaked, riding me like she’s been waiting weeks. She leans down, tongues her own juice off my shaft, then tells me to fuck her harder. I slam until her pussy squeezes around me and she’s cussing, begging. Right when I’m about to bust she drops to her knees, takes the whole load in her mouth and swallows every drop like a champ.
