[GVH-693] My girlfriend's sister Kana, who found out about my masturbation abstinence, gave me a teasing blowjob with staring eyes that prohibited me from ejaculating, and made me ejaculate repeatedly without warning, then swallowed it. For five days, (Censored)

My girlfriend has recently fallen for a stoic guy who looks like a Korean idol, and seeing how self-indulgent I am, she told me, "I'll break up with you if you don't do muscle training!" What's more, my testosterone levels are dropping, so I have to abstain from masturbation! But seeing me in such a pathetic state, her sister Kana starts a sticky, annoying blowjob that doesn't allow me to ejaculate! There's no way my no-masturbation dick can withstand it and it erupts right away! Kana gleefully drinks my semen, and then she gives me a cleaning blowjob to bully me, repeatedly stripping me of my human rights and my sperm... #Team Leader P
