My pregnant step-sister is taking a bath, and I can't resist the urge to peek in on her. Through the crack in the door, I see her lounging in the tub, her massive, swollen breasts barely contained by the water. I'm ********** by the way the bubbles cling to her curves, accentuating every inch of her sensual body.She notices me watching and smiles, a mischievous glint in her eye.'Come here, little step-brother,' she calls out, her voice low and inviting. 'I need some help washing up.'Ienter the bathroom, my heart racing. She hands me a washcloth and some soap. 'Start with my tits,' she commands. 'They're so big and heavy, I can't reach them myself.'I kneel beside the tub, gently lathering the washcloth and running it over her enormous breasts. They overflow in my hands, the nipples hard and leaking milk.
