@34: All the obsessing he was just doing over her body and of course they asspull a blowjob out of that for him instead of naturally proceeding to some passionate cunnilingus for her. Thanks Japan.

[Synopsis]
Manami always told Tomo, "Find a proper girlfriend and date her instead of your mother" so he decides to give Naoko a try. But once they start dating, they end up constantly fighting and becoming troubled. Meanwhile, Tomo is unable to break off his relationship with Manami and unwillingly ends up in a two-timing situation. With her voluptuous body and huge breasts and usually appearing to be a tough mother but actually being a very kind and beautiful woman, Tomo's mother is the woman of his dreams. Eventually, they begin having sex and she accepts any of Tomo's erotic requests. Whenever she visits Tomo's apartment, his mother is always braless, arriving excitedly in her son's preferred underwear and clothes. Naturally, they also enjoy sex while dressed as a bunny girl. One Sunday, at Naoko's request, she and her mother join her for dinner at Tomo's apartment. It's the first time they've met face-to-face. What will happen?! Anyway, Tomo sneaks a naughty prank on his mother while she's not looking! And then, unexpectedly, Tomo makes two decisions...!
------------------------------
Mother: Noda Manami (43) Normally a vibrant, courageous mother, she has incredibly large breasts. She dotes on her only son so much that her excessive sex education eventually leads to an incestuous relationship between mother and son. She finds her son's occasional assertiveness endearing and she accedes to any of his naughty requests. Today, she continues to visit her son's apartment, telling herself that her son should officially date his younger girlfriend, Naoko and that she is merely a shady sex friend.
The son, Tomo Noda (20) is a rather handsome young man but he's actually a pervert who has been obsessed with sex with his mother for several years. Naoko, a new employee at the company, unilaterally forced her affections on him and they ended up dating. He initially thought incest might be a bad thing and resolved to distance himself from Manami, living alone. However, this has actually made it easier for him to avoid his father's eyes and he now enjoys free and passionate sex with his mother in their apartment.
The girlfriend, Naoko Zaitsu (19) is younger than his age and in love with Tomo. She arbitrarily decided that Tomo, who treated her kindly as a senior when she joined the company, was her ideal boyfriend and ended up dating him like an uninvited wife. Because she forces her ideals on Tomo, they often get into arguments. She is proud of her slender figure but that doesn't suit Tomo's taste either.
