The process finally begins

"Unlike the O serum which is administered anally through a suppository, the A and B serum is one that is taken orally and is then fully activated with a penile injection," explained Evan as he moved around the room with practiced ease to prepare all the materials that were needed for the process.

"Penile injection?" asked a shocked Benz, "You're going to be injecting something into my penis?!"

"Yep. Don't worry. It won't hurt too much. Just a bit of a tiny prick down there," replied Evan casually as he finished the necessary prep work. Satisfied with himself, Evan put on some gloves and directed his full attention to Benz.

"You're up first, Benz," Evan motioned to Benz, "Please take off your clothes."

It takes a moment for Evan's request to sink in but once it did, Benz followed through with aplomb and used the opportunity to flirt with the cute, young scientist who he was crushing on. Deliberating taking steps to flaunt and accentuate his well-developed and muscled frame as he stripped down to his underwear, Benz made sure that Evan could see what he had on offer.

At first, you were slightly jealous of the fact that two of your lovers were flirting with each other in front of you. But soon enough, these feelings of jealousy dissipated and were replaced by lustful thoughts of all the possibilities and fun the three of you could have together. Amused by the scene that was unfolding in front of you, you began to develop a couple of ideas to get your rocks off while helping these two along. If all things go well, Saturday would be a fun day for all three of you. Shaken out of your reverie, you can definitely see that Evan is liking what he was seeing but he was doing a good job of hiding it. But having been with the young nerdy slut many times before, you knew better and could see that his eyes were lingering and moving downwards as Benz did his strip tease.

Finally, with only his underwear left, Benz hesitated briefly before pulling down his underwear to reveal his soft member. Knowing that his soft member was not that impressive, Benz blushed profusely and tried to casually cover his now exposed genitals with his hands.

Seeing Benz in distress, Evan offered Benz a medium-sized vial that had a "B" label and moved the process forward, "Please drink this. It has a slightly unpleasant and bitter taste but it should go down quite quickly."

Benz reached out and chugged down the drink, his face scrunching in a frown as the bitter taste filled his mouth.

"After a few moments, your body will heat up and you will feel a sudden bout of arousal. Don't be alarmed by this. That is a normal side effect of the serum," Evan continued his explanation, "Once you have an erection, I will then inject you with the other dose to activate the serum. Afterwards, you should make your way to the bed. I will dose you with a sedative so that your body can rest while the serum integrates into your blood stream and DNA. When you wake up, the serum's effects should be fully realized."

Benz nodded in acknowledgment and soon enough, his body started to respond as Evan had explained.

Seeing that the serum has started to have its affect, Evan went about with his tasks and soon enough, Benz was safely sleeping on one of the clinic's beds.
