Stealing Mother from the Deadbeat Dad She Can't Leave: Pursued, Loved, and Taken Away

Ever since he could remember, MC has lived in the hospital. His beloved Mina-oneechan has been gently and attentively taking care of him day after day. Shota used to innocently tell her, “When I grow up, I’m going to marry you, Mina-oneechan.”

Ishidou Narumi, a student attending a rural all-boys' school, spends his noisy but enjoyable days with his slightly ditzy best friends.
He has a "secret" that he has not made public.

In this all-male school is a popular, gentle health teacher named Mitama, who seems to be the human embodiment of healing.

Another one is Aya, his homeroom and chemistry teacher, who is feared because of her sharp eyes and strict attitude, but is also popular because of her model-like appearance.

As the only ladies in a school with no female students, these two women and Narumi have a "special" relationship that they do not tell anyone about.

Although they act respectable at the school, it's all just a facade. The truth is that one is a spoiled, no-good Oneesan, and the other is a timid worrywart born with a bad look in her eyes. Since he happened to know those sides of the girls, Narumi has developed a particularly close relationship with them.

However, they were still teachers and student. No matter how close they were, there was a line they would never cross. But the situation changes drastically when an enfant terrible named "Patricia" enters the picture.

Patricia (aka "Patty"), arriving as an English teacher, falls in love at first sight with Narumi after a certain incident. Being a bundle of energy, Patty quickly makes a move on Narumi (in a naughty way)...
From there, his relationship with Mitama and Aya begins to change.

Who will win this sudden battle?

Mitama, the pampered Oneesan?
Aya, with the face of a wolf but the heart of a rabbit?
Or Patty, rushing headlong into everything like a wild boar?

It all depends on Narumi's lower half...?

A girl suddenly appears in my dream, revealing herself to be a succubus and proposing a game.
If I win, I'll wake up from the dream.
If I lose, I'll be her sex slave for life, having my semen extracted until I die.
The game is tag.
If I'm caught, I'm tempted and ejaculate, and I lose.
However, the girl says it's a handicap and doesn't touch my penis at all.
She says she'll play with my penis if I ask, but that would be tantamount to admitting defeat and declaring my willingness to become her sex slave.
Can I resist the temptation of this bratty succubus and my own desires?!

Seiki was currently living with his in-laws.
With the current situation, his days of remote work continued.
The cause of his current distress was the decline of sex with his wife.
Furthermore since multiple generations lived under one roof, it was difficult to find the timing to masturbate.
...In that case, the only choice left was to do it while he was working.
But in middle of the act, an unexpected visitor arrived.
Manae, his mother-in-law, who was supposed to have gone shopping.
And thus, without even having the time to fix his appearance, he was seen.
