A group of five slightly shy and shy liberal arts girls research sex through lesbian play in order to draw erotic manga! A loose and fluffy after-school youth club activity story! Since they have no connection with boys, they use their bodies to kiss, caress, and even bring out strap-ons for lesbian sex! They make the excuse that it's for the manga, but their sexual desires run wild in a space with only girls! Wanting to test the results of their research, they take out a harmless-looking boy and have practical sex with him using his bare penis, saying, "I won't tell anyone, so lend me your dick!"
