Azuma Marina

In Kashidashi Tsuma, Marina no "Netorase" Houkoku Binkan Tsuma to Zetsurin Daigakusei, Marina has sex with her co-worker Hiroto. While she is far more experienced than him, she still finds him "cute", and even lets him cum inside her unprotected while nestled between her big breasts. Their relationship deepens with each fuck-session, and Marina even allows Hiroto to kiss her and have raw sex, blowing his creamy cum inside her multiple times. By the end of the game, she feels safe enough with him to fall asleep in his arms while in her own bed, treating him more like a lover than a sex friend. Despite her intimacy with Hiroto, she still remains committed to her husband, even if she does admit that Hiroto is better at sex than Kenji.

Marina is shown to have a mischievous side. While being "loaned-out" was not originally her idea, she gets into the play rather quickly, taking pleasure in teasing Kenji while recounting her sex with Hiroto. She also enjoys withholding information from Kenji (such as the fact that she let Hiroto blow his nuts inside her unprotected on their first night together), to outright lying when claiming that she and Hiroto aren't having sex, even though she rides on top of Hiroto's cock. She even becomes brazen enough to let Hiroto play with her breasts and kiss her in her own house, even though Kenji is in the next room.

Marina is a particularly wild lover, as demonstrated during her fuck-sessions with Hiroto. They have sex in numerous positions: she drapes her shapely leg on his shoulder while he thrusts in her standing up. They have sex in the shower and bath multiple times, fondling each other as they wash up, which also leads to more fucking. Marina shakes her sexy ass right in front of him, causing Hiroto to take her from behind, and slide his big cock into her pussy raw. She rides Hiroto in the cowgirl position while on the phone with Kenji, until he makes her cum, allowing Kenji to hear her “o-voice”. During their hot springs trip, they fuck the entire night, even doing it in the 69-position so she can drink his hot semen while he buries his face in her perfect butt, until the sun comes out. It's also implied that they may have had sex in the hot springs too.
