An office lady working at an import goods trading company, met through work connections, is invited to appear in an adult video. Wanting to experience a new world of things she could never do normally—like threesomes and double blowjobs—she agrees. Under her clothes, she hides enormous breasts so large that no man's hands could ever fully grasp them. She suddenly appears in an unguarded shower room, asking for a titfuck. Though shy at first, she actively performs, even giving a thorough cleanup blowjob. Her genuine, amateurish reactions during her first-ever threesome—writhing in overwhelming pleasure—make for a must-see performance!
