Nakamura Hiroto

At first, he is shown to be rather inexperienced when it comes to sex; during his first time with Marina, she easily overwhelms him, making him orgasm quickly several times. Over time, he improves considerably, at one point becoming bold enough to jump her from behind after being turned on by her sexy butt. He also teases her while she is on the phone with Kenji, making her loudly orgasm, which she is unable to hide from her husband. While she is initially upset, Hiroto is unfazed, and cheekily flirts with her in response. It is later revealed that he actually masturbated before meeting her for sex, so that he wouldn’t cum immediately. Marina pouts while hugging him against her breasts, telling him that she likes him for who he is, and that he doesn’t have to impress her like that. The two make tender love after that while in the bath.

He is shown to have high endurance, able to cum a large number of times while having sex with Marina. He begins working out to increase his stamina, and is even able to make Marina cum multiple times without blowing his load prematurely. While in the shower, Hiroto pulls out of Marina and ejaculates, covering a sizable portion of the glass with semen. During their trip to the hot springs, Hiroto blows a huge load inside her pussy, only to pull out and spray an equally large amount of cum all over her body seconds later. His cumshots are also powerful, so much so that Kenji can hear him ejaculating into Marina over the phone.
