LULU-356 My busty gyaru childhood friend, Haruhi Moka, couldn’t stand seeing me struggle with my overly sensitive body, so she kept teasing me with a nipple-focused hold to help train my premature, weak little member, even after I got carried away.

I was having a home date with my first girlfriend when my childhood friend suddenly showed up. I spilled wine on my chest, and she wiped it off with a towel, but the friction around my chest made me climax unexpectedly. I thought she would tease me, but instead, seeing how sensitive I was, my childhood friend helped me train my sensitivity by teasing my nipples. She also became my practice partner, helping me improve my stamina through intimate training. My childhood friend had always been like an older sister since we were kids, but I never expected her to be so caring. Thanks to her support, I grew into a more mature man.
