Unrivaled!! Childhood Friend: 48 Hours of Uninterrupted Training

"Only 2 days of continuous sex and I've already reached my limit, huh."

I got reunited with my older childhood friend Yuma-nee at a welcoming party. Exploiting her competitive personality, I succeeded in getting her to drink a lot of sake to get her smashed; and then under the pretense of nursing her I took her with me to a hotel, and there I brought up the idea that we play a game for adults.

We follow a simple rule: in this sexual showdown, the first one to give up loses. The opening bell rings starting with a kiss, with the slow and sticky entwining of our tongues serving as preliminaries. I have to gain the initiative by stimulation so I can get to squeeze Yuma-nee's big boobs, and finally my hands move on to her privates.

My thing won't settle down from cumming just once or twice. Until Yuma-nee taps out, we'll do consecutive rounds to fuck with no time to rest!
