[Toyoko Daisyouten (Yamada Kintetsu)] Sweat and Soap: The Childmaking Book (Ase To Sekken)

Asako, a bespectacled woman with a tantalizingly thick, curvy figure, and her lover Kotarou give in to raw desire as they decide to forgo protection during a fiercely passionate encounter. Drenched in sweat and lost in each other, they abandon caution, with Asako's glasses askew as she eagerly takes him into her mouth before a deep, intense coupling pushes them both to the edge. The morning after brings a hilariously messy consequence when their reckless night results in a very obvious, dripping wardrobe malfunction they must address before another round in the bath.
