Eyes still half-shut, I feel the mattress dip. Step sis slides under the blanket in tiny cotton panties, presses her soaked pussy against my morning hard-on and whispers “fuck me quick before mom knocks.” She yanks my boxers down, climbs on top and sinks raw onto my cock with one desperate drop. Bed creaks softly while she rides fast and silent, hand over my mouth, eyes wide with panic and lust. Her hips slam down, pussy already pulsing, moaning “hurry” into my neck. Thirty seconds of frantic grinding and she bites my shoulder to muffle her orgasm. I thrust up hard and unload deep inside her just as mom’s footsteps echo down the hall. She slips off, cum dripping down her thigh, kisses me once and vanishes like a ghost.
