Makina, Denji's new bunny-girl companion, can't resist the temptation of his big cock, even as she's supposed to be watching over him. In the hot spring, she sneaks away to meet her lover, who fucks her hard in missionary and cowgirl positions, making her moan and beg for more. Meanwhile, Denji, unaware of her cheating, plays with his chainsaw, ready to protect her at any moment.
