The first installment in the erotic comedy series. Kyoko Maki suddenly appears at a share house where masochistic men live together. Immediately, she's asked, "Can I keep a pet?" and then demands, "I do yoga, so can I borrow some space?" Though initially awkward in front of the senior residents, she proceeds to perform yoga while flaunting her big tits, spreading her pheromones everywhere. Her provocative actions continue into the quiet of the night... The main feature thoroughly captures these explicit moments.
