In the sultry embrace of an open-air hot spring, Nono and Momoka's bodies entwine, their inhibitions melting away like the snow around them. Nono's eager lips wrap around Momoka's stiffening cock, her tongue swirling around the engorged head. Momoka's breath hitches as he fights the urge to explode into Nono's waiting mouth, the cool night air contrasting with the heat of their bodies and the steaming water lapping at their skin.
