Step sis bursts in still in her tiny skirt and crop top, backpack slung over one shoulder, whispers “fuck me fast before class.” She drops to her knees on the bedroom rug, pulls my cock out and swallows deep while looking up begging “on my face.” I grip her ponytail, thrust hard down her throat until she gags sloppy, drool running down her chin onto her perky tits. Minutes of frantic sucking and I pull out, explode thick ropes across her pretty face and open mouth, cum dripping down her cheeks and glasses while she licks her lips laughing “perfect makeup for school.”
