Mark got his lips plumped

"Then let's see if we could solve it." Dr. Summers went over to Mark. She took a syringe and injected its content into his lips. They got fuller and thicker until they were really plump. "As you can see, he now has cock-sucker lips." Dr. Summers turned towards Mark. "You love cock-sucker lips, don't you?" Mark didn't protested, instead he bit his lips. Dr. Summers smiled. "Then lets give you something extra." She got a bottle of pink lip gloss and applied it on his plump lips. They looked out of place on his male face, but they really were the image of stereotypical cock-sucker lips.

Dr. Summers untied Mark and helped him stand up. She slowly pushed him forward. "You have suppressed your desire long enough, now let it out." She pushed him over to Leticia, who's pants had gotten unzipped by one of the women, who had **** you into this room. Mark was pushed in front of Leticia and there down to kneel before her. Dr. Summers put her hands inside of the new woman's pants and stroke her penis until it was standing up. "How is this, Mark? Is this the thing you desire?" She whispered into the boys ears. His eyes were fixed on the dick before his eyes. Slowly his head moved forward until he wrapped his plump lips around the tip. Once the ice was broken, Mark went all the way down on it and the vaultings on his cheeks showed he was sucking as he moved up.

"How does it feel to get sucked off by a boy?" Dr. Ryan asked Leticia as Mark speeded up.

"Why are you doing this to us?" She asked.

"This is a punishment for the both of you, though Mark may think of it more like a liberation." Dr. Ryan replied.

"Last time I brainwashed him to really love sucking cocks." Dr. Summers explained. "It's a miracle he didn't jumped any of you, or his teacher, who has an even bigger cock than any of you."

Now his shy behavior over the last days made sense. He tried his best to suppress his brainwashing, but in the end he gave in.
