Uta and her father Suguru, along with his two friends, are chatting in the living room. The two friends are already drinking.
"Uta~ Dad has a business dinner again tonight, and I can only count on you two to look after her. It'd help if you could keep her company over some drinks once in a while. She likes reading books, you know."
"Uta, make sure you don't cause trouble for the uncles."
"Suguru, what time will you be back?"
"I think I can make it before the last train. Well, I'm off."
Father Suguru leaves, and Uta is left with the two uncles. The viewer will sense that something is about to begin from this moment.
"Uta-chan, what have you been into lately?"
"Othello and Twister."
"Twister? You know Twister? I only learned about it after starting work."
"I play it with my friends. The rules are simple."
"Want to try it with us uncles?"
"Wow, I haven't heard about Twister in ages! Let's do it!"
"Yay, let's play! I'm really good at it!"
Uta is as sensitive as a small animal, reaching climax while trembling. Her tiny body being creampied in raw sex is exactly "a record of being thoroughly played with by Daddy Suguru's uncle friends." Through the uncles' hands, Uta is gradually swallowed into a vortex of pleasure.
