Curvy brunette step sis strolls into the room, hair down, just as her little brother’s hand jerks off. No warning. Zero hesitation. She grabs his dick mid-stroke, pulls him up—cock slides right in before she even finishes yanking down her panties. Ass up, face down on the bed while he fucks her like she’s been waiting years for this. Hands grip hair so tight it hurts when she slams back down each time. ‘Harder,’ she breathes between moans, nails digging into the sheets as he pounds up from behind. Cumshot hits deep inside—no pullout. She takes every drop and keeps coming until the mattress is soaked.
