【Eru-Pi-Suta-Jio】Amaamamasu 3! ～Beware of Flag Disturbance! YUWAKU OBAI KAGAKUSei! ~ (Japanese only)

Full breasts that don’t fit her age, with excellent proportions.
This is the first time I’ve ever seen a girl with such big breasts attract attention from boys.

They all have had contact with Kazuki (the main character) in the past.
In the event that you’re not sure what you’re looking for, you’ll be able to find it here.
In the event that you are a member of the game club, and you are the only one who has joined the club, then you should know that you are not alone.
Each of them made repeated approaches in an attempt to get Kazuki’s attention.

The balance, which has been maintained for a while in a three-way tie, is now
One day, three of them confess at the same time, and it all falls apart.

Kazuki was confused by the sudden situation, but the girls told him

'I’m going to spend some time with each of them as if they were my girlfriend for a while.
He proposed a temporary girlfriend period, and I ended up going out with all of them on a trial basis.

After that, the approach of the three of them became more and more extreme.

“Senpai…I’m no stranger to big boobs…touch them and see for yourself.

What if the loser of the game can order each other to do anything?
[Why don’t you try something like the naughty game that Itsuki has?]

Kazuki is tempted by three men with bodies as erotic as a glamour model’s, and his rational mind is shaken out of control…

What is the end result of this sweet harem route with boobs and underclassmen?
