Riley can't do it

His reason caught up to him. Why was he jerking off just because the hot doctor told him to? This was wrong on soany levels!

"Why have you stopped?"

"Well... it's just... weird.... I don't want to."

Dr. Samantha continued to gaze at him like a predator sizing up her prey.

"That's fine. Can you sit down on his chair then?"

When Riley sat down, he was alarmed to see the doctor standing over him while she fiddled with some equipment. His erect cock was so close to her thighs that just a slight thrust would make them touch. When the doctor leaned forward, Riley could see straight down her blouse.

"Alright. Since you refused to comply, I'll use this automatic semen collector."

Riley was too distracted by the doctor's cleavage to notice what she was doing until it was too late. His arms and legs were strapped down to the chair. It was impossible to break free.

"What is this? You can't do this! This is ****!"

The doctor sighed, the first emotion he had seen on her frigid face.

"Dear Riley, I'm just doing my job. Please don't make this harder than it has to be."

In her hand was a cylinder attached to a thick tube. She grabbed his cock and slid it into a small opening in the cylinder, which Riley found to be made of some kind of soft and wet material in the inside. It felt... good.

A moment later, the doctor flipped a switch, and the automatic masturbator began stroking and sucking on his cock. Riley squirmed in his restraints, trying to withstand the unrelenting stimulation to his private parts.

To his horror, he heard the nurse call out, "Next!". The curtain parted, and a student in a female uniform walked in. Riley's heart dropped when he realized it was Lisa, his crush. Her eyes widened in surprise when she saw Riley naked and strapped to the chair. As her shock wore off, her lips instead curved into a mocking smile.

"Hi Riley. That's such a cute and small penis you have..."

A bead of tear rolled down Riley's cheek. The doctor started her medical inspection, completely ignoring his presence. She even asked Lisa to strip, but only down to her underwear. Riley felt a minor joy at getting to see her in her cute pink bra and panties.

In that moment, the pleasure in his cock reached the point of no return. He started to cum into the device while staring at Lisa's boobs, and the device hungrily devoured his cum with loud slurping noises. Any hope of them not noticing was dashed, especially when the machine did not stop milking him after orgasm and the over sensitivity made him audibly moan.

"It appears Riley has ejaculated. He probably got too excited seeing you naked," Dr. Samantha said. Riley glared at her angrily, convinced that she was intentionally bullying him at this point, even though her expression was neutral.

"Please doctor... I already came... let me go now."

"Wait..." she walked over and checked a panel on the extraction machine. "This isn't enough. I need another load."

Riley's heart sank. His cock was already going limp, how was he supposed to ejaculate again?

"Oh, I see your weak penis is already tired from just one load. Don't worry, I have just the thing. Lisa, could you help pass that rod on my table?"

"This one?" She asked, holding up a metallic rod about ten inches long. The doctor nodded and she came over, still wearing her underwear.

"Now, take that bottle and slather the lube over the exterior."

Wait... why did that thing need lube? What exactly were they going to do with it?

"Now, take the prostate massager and insert it into Riley's anus. Push it all the way in."

"No no no no don't do this!"

Lisa did not even hesitate for a second. She shoved the rod up his ass in one smooth movement. Held down by the straps, Riley could only scream out in pain as the cold metal lanced through his rear.

"Don't be such a wuss, Riley. The doctor knows best," Lisa chided.

Does she really? Riley was starting to feel like he was trapped in a nightmare.

"Alright, press on the button at the base of the massager."

Riley immediately bucked against his restraints when the massager turned on and began vibrating at a high frequency, pulsing against his prostrate from the inside. He had never explored that part of his body so it was an entirety new and foreign sensation.

"Aaaaaaaaaaahhhhh! HOLY CHRIST!"

Little by little his cock began growing. It did not reach full erection, but was hard enough that the extraction machine was able to milk him again. Lisa's medical inspection proceeded and ended while he was subjected to the apparatus's ****. Before long, he started orgasming again, and shot out more ejaculate into the machine.

Finally the doctor switched off the machine and released him. Riley slumped down onto the ground, his entire lower body feeling like jelly.

"Your medical examination is done. Please leave so that the next student can enter."

"Wait... I need to get dressed. Where's my clothes?" He could not see them on the tray he had left them on.

"I don't know. Maybe someone took it. Why don't you go ask your classmates?"

"What, like this?"

"Yes. Nurse, please escort this young man."

"No! You can't-" His pleas were cut short when a buff nurse grabbed his arm and pulled him out of the examination area. Suddenly he could see all of his classmates, and he was still naked. All of them turned to stare. Some laughed, some whistled.
