Coralee is invited by her college chemistry professor to take part in a taste test study for a new candy. Right away the taste is like nothing she's ever had before. She feels a sense of warmth and comfort as the sensation of her hands feels amazing against her body. Her pussy gets wet as she sucks harder on the candy before catching herself. "Why do I feel so good?" "The candy is called Euphoria is an all natural supplement that opens the pleasure sensors" he explains and she gets nervous. "We can stop if need, just lie down and the sensation will pass." She nods and he takes her over to a bed. She moans as he helps her out of her shorts, his hands feel amazing on her body. But as the sensation passes she finds herself craving another taste. "If we move on to phase two it'll help alleviate the symptoms..." She agrees and he offers her his fingers to suck on. She hesitates but taste them into her mouth. She moans and sucks harder, licking his fingers, the taste is amazing. "Why do you taste so good?" she asks. "Because I infused my DNA with the candy, so tasting me now gives you the same feeling as the candy." he explains as she sucks lovingly from her knees. "If you want to keep tasting I need you to get me hard" Without thinking Coralee reaches over and rubs his cock. "Please let me taste you professor" she begs. "Call me master" he commands. "No, I'm not your slave" she says as defiantly as she can, but when he stands to leave she grabs at him. "Please don't go, please don't go...master" He has her strip and then lets her suck on his cock. She bobs up and down, before fighting her urges one more time "What am I doing?" she says as she crawls onto the bed. Before long she's, moaning "I need it. I need it." "If you stroke it I'll let you suck my fingers" she reaches over and does as he commands. "Look at that precum" he says and swipes a drop onto his finger before feeding it to her. She can't resist any longer and sucks him off, begging for him to feed her until he fills her mouth. "Swallow" he commands knowing that once she does, she'll be his completely. --- [SLOW MOTION BJ] She's lost in a haze of pleasure, one day blurring into the next as she uses her mouth to pleasure him endlessly. She doesn't remember when he first put the collar and leash on her, but she doesn't care...anything to make him happy, anything to make him hard. [Return to regular motion] She begs submissively are she pleasures his cock with her mouth. She offers herself to hime completely, she's his little fucktoy. She'll do anything he commands. Anything to taste him. Anything to make him cum in her mouth again.
