【Tiramisu】What kind of erotic game is that? My tsundere classmate has become my sister-in-law!

[synopsis]

The protagonist is attracted to his classmate [Maho Hashimoto].

But when the protagonist’s father and Maho’s mother remarry, the two end up living together as brother and sister-in-law.
In the beginning, the protagonist was excited to be able to get along with Maho.
However, the cautious Maho doesn’t open up to him and asks him to keep his distance.

I’m sure you’ll be happy to know that I’m not a stranger to you, so don’t try to be a stranger to me!

The protagonist is so concerned about Maho that he abstains from masturbation and shifts the time he goes to and from school.
I’m so exhausted.
One day, the protagonist happens to bump into a naked Maho in the bathroom.

“Idiot! Hentai! Get the hell out of here!

In order to relieve the frustration of being abused, I masturbate with Maho for the first time since I’ve been living with her.
When the protagonist returns home after masturbating and taking a walk for a change, he hears Maho’s voice coming from inside his room.
What a surprise! Maho is masturbating with a tissue that has been cleaned up with the hero’s semen!

I’m sure he’s masturbating with me every day. I’ve been trying to keep it together…]

The main character continues to peep at Maho to keep her from noticing, but accidentally makes a noise.
Maho realized that the protagonist was watching her and rushed back to her room to escape.

In fact, Maho has also been masturbating on a daily basis, but she’s been holding back ever since she moved in with him…!

The protagonist asks Maho to give him a blowjob on the condition that she apologizes for what she has done and doesn’t tell anyone about his masturbation.

I’ll make you feel better for sucking my dick.

Maho refuses, saying it’s a stupid offer.

“No, I think I want you to make me feel good too…

A few weeks later. A few weeks later, the protagonist and Maho have made it a routine to serve each other.
And their curiosity about sex has reached its limit.

[I’m curious too].
[Oh, I’ll have sex with you if you insist!]

[heroine]
