At first I was… whaaaaaaaaaaaaaaaaaaat ? IS THAT SUPPOSED TO BE A GINTAMA PARODY ?!?
But then, some web searching later, yeah.
If you were, like me, completely unaware, there has been in 2013 a “Be Forever Yorozuka” Gintama movie, taking place five years into the future, and in which Kagura is at last a good-looking adult, in which Shinpachi looks cool like a bishie and shit (please, someone tell me he is still straight-manning ? His “real” non-mature future alternative would be this).
End of what I figured out, beginning of this doujinshi : Kagura isn’t that reluctant to having sex with a super-weird guy, actually Gintoki under disguise, and with Shinpachi too. And so, with lots of comedy, vaginal sex, and double penetrated Kagura.
Me, mostly :
But, hey. Kagura having sex ? /NEED !
Thanks to Doujin-Moe for this UFO of a hentai release ^^;;
