Feeling his sister shuddering beneath him drove Victor over the edge. Forcing the swollen head of his cock up against the entrance to her womb, Vic started to cum as his little sister's so recently innocent body spasmed around him. As she quaked with orgasm, he pumped an incredible amount of sperm into her. Groaning in pleasure, he pressed his face against Luna's and licked her closed eyelids, whispering "She's cumming, she's milking her brother's load into her".<br/><br/>Briefly resting in the forced embrace of his littler sister, Victor let his heavy load flood deep inside of Brooke. Slowly he pulled himself out of her, the wet noise it made as it broke the tight suction seal of her tiny hole the loudest noise in the room. Standing at the foot of the bed, Victor admired the sight - Luna seemed like she was nearly catatonic with shame and surprise; kneeling with just her camisole on, she straddled Brooke's mouth, leaning slightly forward with her arms bound behind her back with the leather-belt. Brooke's tan skin was flush and sweaty from her ordeal, her fat breasts heaving under her t-shirt; the lips of her pussy were red and swollen from her brother's pounding hips.<br/><br/>Pushing Luna's head down by her hair again, Vic said "it's time for you to return the favor to your sister, sweetie", and drove the littler girl's mouth into her sister's cunt. Victor walked around and knelt on the bed behind Luna's narrow ass, his cock already hardening at the lurid sight of his sister's mouthing each other's holes.
