Onii-chan Is Done For! Official Anthology Comic - Vol. 3 Ch. 46 - Babysitter

how will he get pregnant if his brain will go poof the moment he receives sexual stimulation? and what will happen if the pill's effects run out while he's pregnant?

a conundrum, to be sure.

His brain will probably be just fine if he masturbates or has an orgasm. Mihari didn't want him to keep playing R-18 games and told him that to scare him.

I had written a long post saying how we don't know Mahiro and Mihari's exact ages, but apparently we do. They are three years apart. Mahiro is 21 and Mihari is 18 at the current point in the story. So I guess this is Mahiro remembering diaper changes on Mihari from when he was 4-5 years old.
