Gonzalo and the injections

Gonzalo was nervous. He was about to enroll as a new student in an educational institution known for being very strict, and he knew that discipline was going to be difficult for him. At 19 years old, he struggled to obey, feeling like he was already an adult, but if he wanted to enter the university after being a pretty bad student in recent years, this was his only chance. He was attracted to the idea of joining the school's sports team, which had a good reputation and competed internationally at a high level. Gonzalo was an athlete, had a toned body, and tried to take care of himself in general, although he lacked general medical supervision as he always avoided the pre-season physical exams. This time he had no choice. To enroll in the school, he had to first attend a medical examination to which he had been summoned, and he had been warned that if he was prescribed any treatment, it was mandatory to strictly follow it, otherwise he could forget about joining the team for sure, and his studies would be in question. So he went, confident that there would be no problem. When he arrived, the team's physical director indicated that he would personally handle the examination. He was a mature man in his fifties, slightly overweight but attractive, with beautiful green eyes and a slightly gray beard. Gonzalo was attracted to men like him, but it was better not to give too obvious signals just in case... The director asked him to stay in his underwear and first fill out the form with his medical history. Gonzalo obeyed and answered all the questions, which were quite a few, about his medical history, habits, etc. He lied a little saying that he never took drugs, but thought it wise not to confess that he took pills almost every weekend when he went out, or that he often drank too much... The director then examined his throat, ears, looked at the whites of his eyes, listened to his chest, and took his blood pressure. He had him lay down and palpated his abdominal area... appendix, liver, etc. -"You lied, Gonzalo. You drink and do drugs somewhat frequently," - "Well... yes, it's true... but not much. How do you know?" - "From your eyes and your liver, among other things. This has to stop, you can't compete in sports like this and it won't help you with your studies either. I will prescribe a treatment that you must strictly adhere to. First for ten consecutive days and then at least a couple of times a week for a few months." - "Okay, I'll take the pills you prescribe." - "They won't be pills. They will be injections and I will give them to you myself, so I'll know you're not skipping any. I'm going to give you a couple now, turn around and prepare your butt." - "Injections? Butt?" Gonzalo looked terrified... he had only been pricked once for tonsillitis and remembered that it had hurt a lot and he had even cried. He was embarrassed to say he was scared, and if he started crying again he wouldn't know where to hide... but it was clear that things were serious because the director was already preparing the injections as if it were the most normal thing in the world. - "Okay, turn around, we're going to give you the first shot... relax your butt, don't tense it. Come on, you're old enough to be so scared, it's just a moment..." Gonzalo couldn't help but tense his butt... he felt the cotton swab with alcohol rubbing against it, a couple of pats, and a quick pinch, which hurt a little but not much... and then the liquid started to go in... - "Ouch! It hurts a lot... please stop, now, no more... ahhh!" The director kept injecting without stopping, telling him that it was almost over and to calm down, but it never seemed to end and his butt was burning... Gonzalo couldn't help but start crying, and he continued after the injection was finished because his butt hurt a lot... - "Come on, Gonzalito, it's not that bad, you look like a little boy. And I still have to give you one on the other cheek and we'll have to repeat for 10 consecutive days, so get used to it..." Gonzalo turned around, looked at him with teary eyes, and asked him not to give him any more, please, but what the director did was hug him, give him a kiss on the forehead, and tell him not to worry, that the injections had to be given but he would comfort him if he wanted... Gonzalo hugged him crying and the director began to kiss him and caress him lovingly, but very sensually at the same time. He turned him around, kissed his little butt, and seeing that Gonzalito calmed down a bit, he started to... Gonzalo didn't take long to go from crying to moaning with pleasure, especially when the director inserted his fingers while kissing him... They ended up pleasuring each other fully, and when the director told him to get ready for the second injection, Gonzalito knew he was going to cry again but he even felt like it so that the director would console him again, and he had also told him that he would have to give him a thorough anal examination with some instruments...
