"I married your mother so I could have sex with you, Airi..." He gives his swimsuit model stepdaughter an aphrodisiac and indulges in drug-induced sex to his heart's content. She is made to cum over and over again by her stepfather's persistent sex, and gradually becomes addicted to pleasure. He drugs her and rapes her until she faints, then attacks her while she sleeps and gives her a titjob, then has a toy orgasm where she squirts and begs for a dick while he cums inside her. Her beautiful F-cup figure bends as she climaxes repeatedly. She craves her stepfather's dick so much that she can't face her mother.
