Carlitos' Tutor 3

"You seem like a bitch whining, Carlitos", the Tutor said very seriously while inserting a couple of fingers in a way that made him moan even louder.... "I'm going to do two things: first, I'll put you on an intensive vitamin treatment starting now to compensate for the energy loss that all this excitement causes you, which I fear is very habitual for you at your age. Second, once you finish the first box of injections from the treatment, in about 10 days, I'll put a chastity device on you that you'll have to wear always, except when you're with me, and even then, most of the time. I'll only take it off for you to release every now and then, and I'll decide when you've earned it and can."

Chastity? Injections? Carlitos didn't like it one bit... I don't like injections, they hurt a lot, I don't want to, he said. The Tutor looked at him very seriously and slapped him. "I don't want to hear any more nonsense. You need to get two injections a day for 10 days, and I'm going to give them to you whether you like it or not. It's for your own good. Turn around."

Carlitos obeyed, but he got very nervous while watching the Tutor prepare the injection and asked him again to please not give it to him... The Tutor said "That's enough", and started spanking his ass harder and harder until Carlitos apologized and promised to behave. "That's what I like. Don't be such a crybaby, it's not that bad. It's just a moment, you'll see". He approached with the first injection, Carlitos felt the cotton with alcohol and tensed up his ass, dead scared... "relax your ass or it will hurt more". He gave him a couple of slaps and quickly inserted the needle... it's true that it's not that bad, Carlitos thought, but then the liquid started to go in... ufff, how it hurt, it was impossible not to cry... "Come on, Carlitos, don't cry. When I'm done, I'll give you some affection to make you feel better". Carlitos cried like a child and said that his ass hurt a lot, but the Tutor hugged him and started to caress and kiss him to calm him down... "soon it will pass, you'll see"... he also gave him little kisses on the ass and started to eat him again... that did calm him down and felt good... and then he inserted his fingers again while kissing him nonstop... Carlitos was already more calm, although his ass still hurt a bit...

"Do you see that it's not that bad? Come on, turn around so I can give you the second injection, and then I'll give you more affection"

For Carlitos, this mix of pain, pleasure, and affection was something new... it was even starting to not disgust him that much, and anyway, it was better to get used to it because if it was going to be like this for 10 days in a row, his ass was going to hurt a lot... but he would try to think about the comfort that came after... and see if by behaving well he could convince the Tutor not to put the chastity cage on him after the treatment was over...
