The handcuffed student, his cock already hard from anticipation, begged for release as the teacher slowly stroked him, maintaining eye contact the entire time. "Please, I can't take this anymore. Let me cum."
The teacher, a sadistic grin spreading across her face, responded with a chuckle. "You're doing great, student. Now, let's see how much more you can take before blowing that load." She increased her speed, fingers dancing over his sensitive flesh as she toyed with his precum.
His pleas turned into moans and then screams of agony as his orgasm neared. He felt his balls tighten and his cock twitch, but the teacher remained unfazed, continuing her torment. She brought her other hand up to stroke his head gently, eliciting a mixture of pain and pleasure that left him completely undone.
