Kazuho, Minako, Yuzuno, and Sayuki are four high school girls who are always together. Along with Guest, they make five.
The regular event for these close-knit girls is a pajama party held in the tatami room of Sayuki's house, whose parents are frequently away.
However, the weight of the fetishes they each carry is heavy.
They want to satisfy themselves without their friends realizing their warped tastes.
They attempt to make contact with one another, acting as naturally as possible to avoid suspicion.
Their respective desires and perversions intersect, performing an endless chicken race.
I want to pin everyone down and give them a kiss that reaches the back of their throats...
I want to tickle everyone until their faces are a complete mess...
I want to hug everyone tight and just sniff their whole bodies...
I want to treat everyone like babies and talk down to them while they have those melting expressions on their faces...
