Currently on the hunt for a loli shota dojin I remember from a while back. Either the loli or the shota are masturbating alone in an alley after learning sex ed the other comes up seeing this and eventually get to showing each other themselves. It eventually becomes how most stories go they show each other themselves they touch each other and eventually have sex all within this alley. I believe it ends with them talking about coming back to the alley. (might be wrong on that part tho)
