The course had just begun. For Alex, it was his first time in a boarding school, and even more so in one like this, special for kids who needed a lot of discipline and control, young people with raging hormones and little affection for studying.

As soon as he arrived, he was assigned a tutor who was always watching him and even slept with him, to control that he didn't spend his nights masturbating or playing with his phone.

His tutor was mature, plump, pleasant to deal with, and even affectionate, but from what he had been able to verify, he didn't mess around when he had to get serious. In fact, the first night he caught him masturbating and immediately pulled out his belt and left his butt well red and hot. Alex learned the lesson with tears, and was warned that if he continued down that path, he would end up with a permanent chastity cage and some kind of injection treatment, which scared him a lot.

That was also worrying him now. He had woken up with a fever and a sore throat, had gone to the school doctor, and was told to go to bed. The doctor told him that the tutor would take care of supervising him and giving him his medicine, but didn't say what it was or give him a prescription. Every time he went to the doctor, he was afraid of being prescribed injections, but he thought it would be normal to get a syrup and some pills, so he obeyed, stayed in his pajamas, and got into bed.

The tutor didn't take long to arrive.

"Let's see, Alex, it seems you have a strong infection. We're going to start your treatment, but first, we need to take your temperature. Turn around, get on your knees on the bed, and pull down your pants."

"My pants? Why?"

"To take your rectal temperature, naturally, and give you a suppository."

Alex didn't like that at all. He wasn't a kid anymore... but the tutor's face and attitude made it clear that it was better not to complain...

He felt a lot of shame with the suppository, but the truth is that it didn't hurt, the tutor put it in very well. When he inserted the thermometer, it hurt, his butt was very tight. The tutor calmed him down, told him he would put some lubricant on, and it was better.

"Ugh, you have a pretty high fever, so the doctor said that in addition to the antibiotic every 6 hours, I'll also give you another injection for the fever every 8 hours. Lie down and expose your butt while I prepare them."

Alex turned white with fear. Injections? Two in a row and then every few hours?

"Can't they be pills? I'm afraid of injections, they hurt a lot..." he was already almost crying just thinking about it.

"Stop being a child or I'll take out my belt. You're not a kid to be afraid of those childish fears," said the tutor, who was filling the syringes without paying attention.

"Turn around and get ready, relax your butt or it will hurt more."

He rubbed him with a cotton ball soaked in...
