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。
A long time ago, I dated a woman who was just having sex. Leona, who comes right away whenever you call, is a convenient woman who is convenient for handling sexual desires. “I’m getting tired of having sex with this guy.” I dumped Leona and started dating her best friend, Ryoko. More than two years have passed since then, and a dinner party is held among friends for the first time in a while, and Reona and I meet again. I’m lusting after my former sex friend who has become an unmistakable beauty. And when she was away for three days due to her own business, he called Leona… Strangleholds, spankings, restraints, cumshots… I can do whatever I want to my masochist sex friend, even if I don’t want to play with my favorite girlfriend, and for three days without my girlfriend, this guy is my convenient hole.
