First published as a stand-alone e-manga this was recently reprinted in Gacchiri Pleasure Land Vol. 10 [がっちり★快楽ランドvol.10 巨乳女子大生が、女怪盗が、さらに処女天使まで、次々と犯される!]

The splashing noises their genitals make are so loud, you can't even see past.

Anybody who complains about the image quality, apologies. Please note this is the same image quality I got the file from at the JP source. It was originally a manga just for smart phones and small screen mobile devices, so it may not look so great blown up on a computer. That being said, I hope someone might translate it someday, since it's so short. I'm still trying to figure out if the girl actually sees him in the locker or just recognizes him from touching the size of his girth?

Base +6, crazymagic +9
