[The Seiji] Woman with Big Dog (The Shiro Muchi - Yawahada Chookyoo Manual -)

A husband's stubborn decision to keep an enormous Neapolitan Mastiff in their apartment leaves his furious wife Akiko alone with the beast — and her scorn slowly curdles into curiosity. Baring her big breasts and soft curves, she teases the sleeping dog with butter-slicked skin until it wakes and mounts her, the knot swelling deep as she gasps that this wild power is nothing like her husband. When he walks in on the act, their marriage detonates into a jealous shouting match where she refuses to back down, daring him to accept that she might just keep doing it with the dog.
