Even though I told her I have a girlfriend, my private tutor Arina Hashimoto deliberately teases me during lessons, playing with my nipples like she's discovered a new toy. Whispering, "This isn't right—you have a girlfriend, yet you're trembling so much," she grins like the aggressive girl she is, stirring my emotions further. I'm terrified my mind and cock will reach their limits like this—I can only pray for someone to save me.
