Shimizu is tricked by his colleague, the flashy Karasuma, into going to what he thought was a party for old classmates, but turns out to be a mixer with man-hungry women. In an attempt to escape, Shimizu lies and says he’s gay and kisses Karasuma in front of everyone. Even after leaving the bar, the women continue to stalk the two, so they run into a nearby hotel! Drunk and swayed by the mood of the hotel, Karasuma, ever curious, says, “Let’s do it! Just the tip!” Shimizu reluctantly agrees, so long as he’s on top. At first Karasuma complains that it doesn’t feel good, but gradually he begins moaning with pleasure, and Shimizu even starts to think he looks cute…!
