「入念に責めればおっぱいの方がおまんこより気持ちよくなるのでは?」ユーザー様よりご意見を受けたSOD制作陣は女子社員を検体とし身をもって検証。巨乳~貧乳、様々なおっぱいを触診からおもちゃ責め、様々な角度から乳の感度を模索していく。最後の二人は同時に実験。恥ずかしさ倍増で感度にも影響が…?




















I wish there were more works where the woman obsessively focuses on the nipples like this. I really hope for a sequel!
I love that the lab door is left open while they interrogate Nakayama-san. When asked, 'Do you like dicks?' and 'Do you like having your nipples licked?', her answering 'Yes, I do' is great. It's a shame they couldn't make her climax with the nipple toy, but since I'm a fan of Nakayama-san, I rate this highly overall. Even though she isn't a lesbian, watching her perform what was done to her on the female staff as part of her 'research' duties is quite a turn-on. There's plenty of variety, from flat-chested to busty, and even a 2-on-1 scene. However, if you aren't a fan of Nakayama-san or the other actresses, you might find it a bit lacking.
*An experiment that attacks only the breasts 1. Kotoha Nakayama She takes off her clothes and has her breasts checked. Her elasticity was checked, her breasts were pressed against the glass, and her areolas were checked. Take a close-up of it with a camera and check the weight. Check the sensitivity with a brush or feather. By the time I get a massage, an eye mask and oil applied, I start to fidget. She takes off her skirt and focuses on her nipples. He takes off his eye mask, is tied to a chair, and writhes in agony as he is attacked with a brush. A dildo is placed between her breasts and her nipples are attacked. Her nipples are licked, she is attacked with an electric massager, and she cums with a nipple-specific toy. 1 hour so far. From then on, Nakayama will be on the attacking side. 2.Takamatsu She takes off her clothes, has her size measured, is oiled, is attacked with an electric massager, is massaged, has her nipples attacked, is restrained, is attacked with an electric massager, and has a toy used on her breasts, but she cannot cum. 3. Hayano. small breasts She takes off her clothes, has her size measured, is attacked with ice, has her nipples checked through a glass, is rubbed, is filmed with a camera, is oiled, massaged, and has her nipples assaulted. Oiled from behind, tied up, attacked with a dildo, nipples attacked with a clip toy and cumming again 4. Kanda. big breasts She takes off her clothes, has her size measured, sees the position of her nipples through the glass, checks their weight, is photographed with a camera, has lotion applied to her, has her nipples attacked, and is given an oil massage. She is covered in powder, attacked with an electric massager, and has her nipples attacked. She is restrained and attacked with a rotor and cums. The dildo is inserted between her and she cums while being penetrated. I cum with a toy that attacks my nipples 5. Sanke, Kono They take each other's clothes off, their nipples are checked through the glass, they apply oil to each other, their breasts are pressed together, a dildo is inserted between them, their breasts are fondled, and they feel it. My nipples are attacked and I cum. Her nipples are licked. The lotion is applied and they cum on top of each other. Their hands are shackled, their breasts are rubbed, and they are attacked with an electric massager. I cum with a toy that attacks my nipples. Furthermore, I cum with an electric massager Don't show your dick or pussy. A plan that involves no insertion or ejaculation. It's a bit worrisome that the camera shakes too much, but the highlight is Kotoha Nakayama attacking a female employee, and the scene where she licks her nipples is the highlight.
*I bought this because it starred Kotoha. I was very satisfied to see the scene where Kotoha's nipples are played with a lot, although they are not big by any means, but they are sensitive. Also, the other actresses were also feeling a lot of pain with their nipples, and I couldn't help but feel my nipples tingling as well. After feeling her nipples being played with, she ends up getting a naughty stain on her pants, which is probably another point of humiliation. However, it is a pity that they did not focus on that. Also, there were many scenes where I wanted to take close-up shots of the nipples, but the camera that was taking the close-up shots of the nipples ended up showing up in the camera that was taking pictures of the nipples, which was very disappointing.
*As expected, there will be no digressions other than the title SOD Sex Science Lab this time. Only breast torture and nipple orgasm. No clitoris or pussy at all She is particular about not going off the rails and has a variety of breasts, from big to small, so from huge breasts to petty boobs, there's plenty to choose from! The last two people experimented at the same time. Although it is said that it is just two people at the same time, it is too particular that there is no derailment. At the very least, I would like to see an extra part in the extra edition where I would like to see him become frustrated due to his development and improved sensitivity as a result of this experiment, and progress from reckless behavior to sexual behavior...
