"I'm Serious, You Only Get To Stick In The First 3cm, Okay ...?" When I Met My Childhood Friend For The First Time In Years, We Started Messing Around From The Get Go, And We Spent A Week Becoming More Than Friends, But Not Quite Committing Adultery, As We Teased And Tweaked Each Other To Creampie Glory. Yu Shinoda

It's been a few years since we got married, and my relationship with my wife has gone cold to the point of separation. It seems the same goes for my childhood friend Yuu, and we've been complaining to each other over the phone. Then we decided to have a drink for the first time in a while, and I invited Yuu over to my place. A few hours later, as the alcohol keeps flowing, the sexless life gets to me, and I find myself mesmerized by Yuu's body, trying to push her down. She stubbornly refuses, saying cheating is absolutely no good, but it seems she's just as frustrated... and so, with a 'just a little... just 3cm...' we start a relationship that's more than friends but less than an affair...
