Follow the doctor’s orders

“Oh, good boy,” coos Susan as you obediently thrust into her, “Following all of my instructions. You’ll make an excellent subject in my research.”

You hold on firmly to the backs of her thighs as your dick twitches and quivers every time it slides back home inside her. Susan smiles down at you, totally in control.

Suddenly, you hear the door to the infirmary swing open and a pair of footsteps enter the room. Susan grins devilishly and puts a finger to her mouth, ordering you to stay quiet. A bated breath escapes your lips as she runs her index finger down your chest, her soft fingertip dancing down your body before flying away as she reaches your midriff.

“Susan?” A female voice calls from the other side of the curtains, “Everything okay while we were gone?”

“Of course!” Susan replies, “Just helping a young man here with a bit of a headache.”

“Alright, give me a shot if you need anything,” the female voice says before walking away towards the front of the infirmary. Susan smirks victoriously and turns her attention back towards you.

“We’re going to have to be quick,” Susan whispers, leaning forward over you. Her tits brush gently against your face as she kisses the top of your head daintily, “so I’m going to need you to keep being a good boy for me.”

Susan pulls your head deep into her ample cleavage, suffocating you in her mammaries. At the same time, she begins to thrust back into you, riding your cock. The stimulation is mind-numbing. Your oxygen-deprived blood rushes to your dick, growing your cock deep inside of Susan. Her hips move like waves against yours, crashing into you gently but with the **** of a woman getting what she wants.

You feel an orgasm begin to well up from your spine and groan into Susan’s chest. She pulls you face deeper into herself in order to silence you. You feel her hair brush by your head as she leans close to whisper to you.

“Is my good little boy close?” She asks, her hushed voice seductively flowing through you. You nod from between her breasts.

“Then cum for me, baby,” she orders, rapidly rocking on your dick. You can’t take it anymore. Your dick spasms as Susan milks your cock, pulling spurt after spurt of cum out of you and in to her warm snatch. Susan continues to bounce back and forth, each motion producing another twitch out of your member.

Finally, you collapse, passing out as Susan extracts every drop of semen from your system.
