LULU-134: Big-Titted Sister Creampied by Her Shut-in Brother’s Massive Cock

With their parents away for three days, voluptuous onee-san Ichimiya Mikan expects a quiet break—until her shut-in little brother whips out his thick, long cock. Teasing just the first three centimeters makes her knees buckle, and once he switches to a relentless nine-shallow-one-deep rhythm, her resolve melts. Every deep thrust slams against her cervix, sending her huge breasts bouncing wildly as she moans uncontrollably. Resistance quickly turns to craving; she lifts her legs, rocks her hips, and cums again and again. He finishes by flooding her womb with thick loads until her belly slightly swells, creamy overflow trickling down her thighs. For three straight days, the once-proper sister is reduced to a drooling, cock-hungry cumdump—captured in raw, heart-pounding detail that’ll keep you throbbing from start to finish.
