I wasn't such a blockhead who could turn down an invitation from so charming a girl. I went into a love hotel the first time in my life and gave her my virginity.

We didn't have any spare time for foreplay, so I impatiently thrust my penis in and immediately ejaculated with the first movement.

Pretty slapdash finish... I felt quite ashamed, but Senpai gently encouraged me...

In the next two hours, I ejaculated in her vagina five times. With my every ejaculation Senpai's cute moans became louder and my confidence grew stronger at an increasing tempo. "I'm cumming! Cumming, cumming! I'm gonna cum!" I felt unstoppable when I finally made Senpai reach orgasm. I was confident I could solve any mystery.
