Natsuiro Lesson - The Last Summer Time

Tyler woke up in the bunker with three strange girls. Unfortunately, their memories have been partially erased, so no one remembers how they got to this mysterious place. They begin to establish a life in their new reality in an attempt to answer many questions. What really happened to them? Are they related to each other? What awaits them outside? Only you can solve all the secrets and get out.
 
In The Last Pussy: Survival Lesson, you will play as the main character who is locked up in an underground bunker with hot and beautiful girls. Survive in limited environments, complete story quests, interact with other survivors, and of course, experience the intense and passionate atmosphere between the characters.

As Ichimotsu Saoya, a middle-aged physical education teacher, you witness your masturbatory crush, the recent international student Helen Anderson, having sex with a student from another class, Ninomiya.
Now, you must plot your revenge by tricking (or rather, blackmailing) Helen into extra summer school lessons during her summer vacation with a sexual consent contract.
As her teacher, corrupt the young, naive student from America by pushing her to perform erotic actions on you! However, you’re not alone in pursuing Miss Anderson. Ninomiya and his best friend, Sota, are both in the running to winning her heart (and voluptuous body)! View the story through both Ninomiya’s and Ichimotsu’s perspectives as you decide Helen’s fate.
Will Ninomiya emerge victorious to enjoy the final summer festival with Helen remaining his girlfriend? Will the aging Ichimotsu take her as his own prize? Or will Sota steal her away?
Enjoy the many branches, routes, and endings as you choose what happens.

Please note that it is a BLVN.

It’s almost been six months since I was assigned here. Even though I’m late or make mistakes sometimes, having my senior around makes me feel at ease! I thought we were getting along well at work, always joking around with each other…
That day, too, was supposed to end with me just playfully teasing him and giving a half-hearted apology.
Instead, a nightmare of inescapable “punishments” suddenly began. Every time I tried to resist, he backed me into a corner, gradually chipping away at my will to fight back… Before long, all I could do was tremble and obey whatever he told me to do.
From that day on, I became my senior’s sexual relief outlet, used day and night. I was completely reduced to nothing more than his convenient hole…
