NTR.net presents an NTR (cuckold) themed adult video featuring a documentary-style amateur couple project, depicting taboo sex between a real couple and a male actor. This time, the crew approaches a couple visiting an adult toy store, targeting a pair who've been dating for about two months and are deeply in love. They first met at a bar when the girl visited as a customer and took care of the drunken guy, staying the night and having sex. The couple is so passionate they even talk about marriage, which led them to agree—at least in theory—to participate in an AV. Initially agreeing only to discuss it, the production team successfully scheduled a follow-up meeting. Days later, they visited the couple during dinner and explained the details, highlighting the benefits. Surprisingly, just hours after the meeting ended, the boyfriend called back and invited them to a hotel.
When the actress, Haru Kawamura, meets the male actor, they immediately share deep, passionate kisses. Her voluptuous H-cup breasts are groped by another man as her boyfriend watches in shock. When the actor fingers her pussy, she nearly experiences her first squirting orgasm. As he takes her from behind in doggystyle, her massive, bouncing breasts shake wildly while she moans uncontrollably. After multiple intense orgasms, they transition to sex with her boyfriend. Her arousal is stronger than ever, clearly heightened by having just had sex with another man. She gazes happily at the condom filled with cum. After filming officially ends, she heads to the bath with the male actor. Claiming the footage is insufficient, they secretly begin unprotected sex without the boyfriend's knowledge. Her hypersensitive body, already brought to multiple climaxes, squirts heavily from even the slightest stimulation. Finally, the actor cums deep inside her vagina, filling her with thick semen to finish. Despite her initial hesitation, Haru delivered shockingly hardcore sex, leaving a strong impression.
