Tuti and Mario, under the guise of sharing a bed for warmth, can no longer deny their carnal urges. Mario, his cock tenting the blankets, rolls onto Tuti, his breath hot on her neck. Tuti, her pussy dripping, grinds against him, seeking friction. They kiss, deeply, their tongues entwined, as Mario's hands roam Tuti's body, squeezing her breasts, pinching her nipples. Tuti gasps, guiding Mario's cock to her entrance. Slowly, inch by inch, he slides in, filling her completely. They move together, their bodies slick with sweat, their moans echoing in the silent house, their incestuous love consuming them whole.
