Lets post doujin where the guy cums a ridiculous amount of times.
This one is : [Poppenheim] Takamiya-kun no Hanayome Shugyou
[Agata] OneShota Volleyball - Intense Training in the Training Room!
He cums at least 15 times !
[Kikuya (Kimura Naoki)] H na Omise no Toku A Kyuu Toushi 3 Kaiten
10 cumshots in this one.
(Chiba Toshirou) Tsukasa-kun's Busy Day
Busy day indeed.
The whole premise of this one is that he can't stop.
There was one with a male student banging a female teacher in a bathroom and he keeps cumming but his dick got kinda huge and it's slowly shrinking down to its original size with each cumshot, I forgot the name...
Sorry for the lack of contribution, I hope someone knows what manga I'm talking about.
He hypnotises the girls, then he hypnotise himself so he could continue fucking forever !!!
[Marui Maru] Shiritsu Meido Gakuen! | Private Maid Academy!
Not a doujin, but highly recommended (translated)
When you want a thread to live on, you start dumping content yourself instead of just sitting back and bumping the thread while hoping someone else will do it.
It's kinda the entire point.
