Only Nipple Play, No Intercourse!

University student Shiori Otokawa signed up for a part-time job, but little did she know it was for a “Nipple Sensitivity Survey”!

What is the Nipple Sensitivity Survey?

The “Nipple Pleasure Research Institute,” a national institution studying women’s pleasure, conducts this survey to investigate the sensitivity of women’s nipples.

Participants: General women (paid daily)

Method: Using sensitivity measurement devices, the participants’ body temperature, wetness, and number of orgasms are recorded. The survey consists of three 10-minute sets, with a one-hour break between each set.

1. First Set: Teasing Sensitivity
   • Conducted with clothes on, focusing mainly on teasing reactions without direct contact.
2. Second Set: Sensitivity to Stimulation Through Clothing
   • Active stimulation is performed over the clothing, including checking sensitivity with lotion.
3. Third Set: Sensitivity During Orgasm
   • Conducted with the upper body undressed, aiming for orgasms with active stimulation. For highly sensitive participants, various methods are used to check for continuous orgasm reactions.

“No way… I’m climaxing just from my nipples…”

Through teasing and persistent stimulation, Shiori experiences multiple consecutive orgasms.

“No… in front of everyone…”

The survey allows interns to observe, meaning Shiori undergoes the sensitivity survey in front of an audience.

Overwhelmed…

Witness the evolving sensitivity of Shiori throughout the survey.

Nipple Sensitivity Survey

What is the Nipple Sensitivity Survey?

Shiori Otokawa, a university student, comes to a part-time job for a “Nipple Sensitivity Survey.”

The survey involves:

• 10-minute nipple stimulation sessions followed by 1-hour breaks
• Only the nipples are stimulated, as explained calmly by the examiner, Ms. Chikuno

Shiori is nervous from the moment she changes into the examination attire and attaches sensitivity measurement devices to her arm and vagina.

Description of the Survey:

1. First Set: Teasing Sensitivity
   • Her areola is rubbed through her clothes, making her nipples twitch in anticipation.
2. Second Set: Active Stimulation Through Clothing
   • The long-awaited nipple tapping feels so good that she ends up soaking her panties and chair.
3. Third Set: Sensitivity During Orgasm
   • Despite taking breaks, the heat in her nipples doesn’t subside, leading to detailed and intense stimulation scenes that are incredibly erotic.

The survey also includes embarrassing scenarios where Shiori is caught masturbating and scolded, as well as scenes of her having continuous orgasms in front of onlookers. These focus on the humiliation aspect, showing Shiori drowning in pleasure while everyone else is seriously conducting research.

The last scene of complete defeat is a must-see. Although there are men in the story, they only appear as background characters, with all the stimulation performed by women.

The Nipple Sensitivity Survey is ongoing, so feel free to apply!

Reader Reviews:

Pure Nipple Ecstasy: If you love nipple play, this is for you! The contrast between trying not to feel pleasure and being overwhelmed by it is fantastic. The breaks between sessions serve as great teasing. The scene where she is continuously watched and judged by many people is particularly enjoyable.

Girls Who Orgasm from Nipple Stimulation: A university student in need of money applies for the survey. She didn’t expect to feel so much from her nipples but ends up having multiple orgasms just from nipple stimulation. Watching her cum repeatedly while being observed by interns was amazing.

Highly Recommended: In the previous work, “Nipple Punishment,” the gradual teasing and relentless stimulation were excellent. This story features a girl with rich expressions, enhancing the humiliation and shame elements. The contrast between the serious research and the girl being pushed to her limits was perfect.

A Must-Have for Nipple Play Fans: This work offers everything a nipple play enthusiast could want. The girl’s expressions as she struggles to hold back her voice while being teased are incredible. The scene of her repeatedly cumming from continuous nipple stimulation is both exciting and satisfying.

Top-Tier Erotic Manga: Following the previous “Nipple Only” work, this one takes it to the next level. The balance between pleasure and shame is perfect, and the depiction of the girl’s psychological state leading to orgasm is superb. The continuous orgasm scenes are particularly noteworthy. The survey’s premise keeps the story engaging, with increasing intensity throughout.

In summary, this work is extremely erotic, making your heart race in sync with the girl’s experiences.
