On my first date with my girlfriend at home, a childhood friend suddenly showed up. She accidentally spilled wine on my chest, and my childhood friend wiped it off with a towel, but the friction on my nipples caused an unexpected explosion in my pants! I thought I would be made fun of, but my childhood friend, who couldn't bear to see this, trained my sensitive body by teasing my nipples. Then she became my sex practice partner and further supported strengthening my premature ejaculation with nipple play sex. My childhood friend, who had been like an older sister since we were kids, never thought she would be this caring... I borrowed her chest or vagina multiple times to have internal ejaculations and had my nipples trained, growing up to be a full-fledged man.
