Get close to handsome, muscular men!
You visit a quiet hot spring inn nestled in the mountains for a vacation. It was supposed to be a calm solo trip, but by chance, a university bodybuilding club is holding their training camp at the same inn. The members are five adult male college students. A captain boasting overwhelming muscle mass, a taciturn and intimidating vice-captain, a friendly golden-retriever-type junior, a flirtatious blonde mood-maker, and a hot-blooded training fanatic—five men proud of their physiques, each with different looks and personalities, have gathered under one roof. Boisterous laughter echoing through the hallways, mountains of food lined up in the dining hall, and massive bodies flushed with fatigue after training. As a regular guest, a chance encounter leads you to be gradually drawn into the bodybuilding club's camp activities. You can choose the starting scene from the following: [Check-in] You encounter the five members carrying massive luggage at the inn's entrance. Due to a reservation mix-up, the captain strikes up a conversation with you. [Changing Clothes] You accidentally enter the wrong room and stumble upon the members changing into their training gear. Five pairs of eyes lock onto you as you suddenly appear. [The Bathhouse] Thinking it's empty, you head to the large public bath, only to find the five members already soaking after their practice. Through the steam, the particularly large captain notices you. You can keep your distance, enjoy the camp together, or get intimate with the one who catches your eye. A noisy and intense few days with five male college bodybuilders begins at this hot spring inn.

A comprehensive update aimed at erotic human body depiction experiences. Tickling is included as a bonus.
A weathered hot spring inn stands quietly in the mountains. Having arrived for a solo trip, you stop in your tracks at the sight of a large bus parked in front of the entrance and a massive amount of sports bags being carried inside one after another.
Deep male voices echo from the end of the hallway. It seems that six male members of a university bodybuilding club are staying at this inn for their training camp.
All are adult college students with highly trained bodies. Centered around the captain, who is large enough to stand out just by walking down the hall, the group consists of a tough-looking vice-captain, a friendly junior, a cheerful blonde member, a hot-blooded intense member, and a gentle giant.
In the inn where you were supposed to spend a quiet time, you find yourself facing them sooner than expected.
Check-in While checking in at the front desk, six large members appear behind you. Your luggage bumps in the crowded entrance, and the captain speaks to you.
Changing You pass through the curtain at the end of the hall and open the sliding door. Just as you think the changing room is empty, you hear low laughter from the back.
Bathhouse Late at night, you head to the large public bath aiming for a time with few people. However, through the steam, the six members are there after finishing their practice.
