Once upon a time, I was just fucking some chick named Reo. She was convenient for my sexual needs because she would come running anytime I called her. "I'm getting tired of having sex with her," I thought, so I started dating my best friend, Akane. It had been about two years since then, and we all got together at a dinner party organized by one of our friends. When I saw how beautiful Reo had become, I couldn't help but feel aroused. And then, out of nowhere, she told us that she would be gone for three days on business... Just thinking about all the naughty things I could do with her during those three days made me hard.

俺は昔、ただヤルだけの女と付き合っていた。呼べばいつでもすぐ来るれおなは性欲処理に都合がイイ便利な女だった。「こいつとのセックスもそろそろ飽きてきたなぁ」俺はれおなを捨てて親友の涼子と付き合い始めた。それから2年あまりが過ぎ、久しぶりに仲間内で集まった食事会が開かれてれおなと再会する。見違えるような美人になった元セフレの女に欲情する俺。そして彼女が所用で3日間不在になるタイミングでれおなを呼び出した…。首締め、スパンキング、拘束、イラマ…本命の彼女には遠慮して出来ないプレイもドMなセフレにはヤリたい放題、彼女がいない3日間こいつは便利な俺の穴。
