Mutsumi-san No Hanshoku Katsudou Kiroku (“The Chronicle of Mutsumi’s Breeding School Club Activities”) chapters 1-5 [English, that particular series is now Complete!], by Tamagoro

“Brains-free sex” perfectly describes this serialization by Tamagoro. You can safely unplug your brain and enjoy, there won’t be hard feelings or particular emotions getting in the way

As for the story: we’re on an island, in which sex is perfectly normal and healthy. Deliciously perverted, sure, but not shunned upon or kept a secret. We follow mostly one of the inhabitants, a slightly plump energetic highschool girl. She’ll first have sex with a sports club members, and next, alongside a lot of other girls, deflower a group of shotas. One of the shotas will become her choice partner, with a happy bonding ending. There’s also a short end of chapter featuring a tanned near-loli with two other shotas, same spirit.
We have oral and vaginal sex with a fair deal of double penetrations. The drawings are good, oozing the love of life and of sex, although I won’t get hysteric over them, perhaps too censored most of the time.

Enough written. I hope you’ll like reading it! ^_^
And thanks to Feildpaint for the second half of the chapter 3, and for everything else, Momo Demon, Giftfrom, Warw90, Dynellen as the commissioner, and Mikocon.com as the raws provider!
