Synopsis
One summer vacation.
Seо, a classmate I’ve secretly admired, is in my room.
Her purpose is to practice “intravaginal urination”…!?
We had decided to “cooperate and accomplish what we want to do” to spend our final summer break without regrets.
What we had in common was curiosity about “trying sexual things.”
However, Seо’s desires were somewhat unconventional.
Since normal sex couldn’t be considered “complete,” she suggested trying something abnormal—intravaginal urination.
But when we actually tried, we discovered it was surprisingly difficult.
1. For intravaginal urination, we must have raw insertion and first need to become accustomed to sex.
2. Even without ejaculation due to raw sex, there’s pregnancy risk.
3. Concerns about hygiene due to the abnormal nature of the act.
4. As a physiological matter, urination is impossible while maintaining an erection.
And we must overcome “5. The psychological hurdle of urinating inside the vagina of the girl I’ve admired”…!
To overcome these obstacles and achieve intravaginal urination, we spent the summer break conducting various training sessions——
78 pages of sexual training to achieve intravaginal urination with a classmate.
