This is what happens when two people in a relationship don't communicate. Really odd that she started out raring to go and then suddenly stopped because... what? She didn't understand how to get going again? Wtf?

Just kidding!

Umi is Francesca Prelati if, instead of being an eldritch immortal, she was a horny gyaru.

To her credit, Nagisa is very pretty but she really has no chance with that bombshell of a little sister as competition.

[Synopsis]

Our protagonist, Taiki, has a girlfriend named Nagisa and life is going smoothly but there's just one problem: they're not having sex.
He doesn't want to break up with her but he can't control his sexual desire...
He decides to call an escort to his house but the girl who shows up is her girlfriend's sister, Umi.
"Let's just keep this a secret between us and have fun", she says.
Swept away by her words and actions, Taiki accepts Umi's service and while he feels guilty, he releases his sexual desire.
