Momoka, a Japanese amateur, discovers an unexpected pleasure in her massage machine. She squirms and moans as it kneads her flesh, her body growing hot and achy. Her panties become damp, and she can't help but grind against the machine's relentless rhythm. In her mind, she's not alone; a faceless lover joins her, their hands roaming her body, their breath hot on her neck. She slips her fingers into her panties, rubbing her clit in time with the machine's pulsations. Her other hand tugs at her nipple, sending jolts of pleasure straight to her core. As her orgasm approaches, she imagines her lover's cock replacing her fingers, filling her, pushing her over the edge into ecstasy.
