Sports Shoujo no Kitaeta Karada ni Bushitsu de Naka〇shi Tokuntokun

"Your hot stuff... it's pouring inside me..." — I was assigned to coach at an all-girls academy known for being a powerhouse in sports, and it's become my job to instruct the students that fall behind. However, the way to do that is... amazingly, through sex! The truth is, my semen has an effect similar to a stimulant as far as I understand; and that's why the board chairman keeps an eye on me and even forcibly transferred me here! In order to reduce the stress on the girls, I vigorously loosen up their tight pussies, slowly insert my dick and then release it deep inside! At first, the girls were also hesitant to do it in a small clubroom that's stuffy from sweat with a thick, naughty scent that fills the air, but it gradually gets to their heads...!? Her tight pussy squeezes me more and more, and her insides beg for my hot bodily fluids...! He frantically does his best for the sake of supporting the girls; The all-girls academy's officially recognized coaching through mating begins!! (Source: DLsite)
