It has taken time to slowly orient my practice toward being a specialist in young men’s health. However, it has been well worth the time and effort. I pretty much get all the twink ass I want. There are times when I have to be careful not to schedule too many needy young men on the same day. I’m a mature man myself, with only so much stamina. I’m not complaining, though. Far from it! Last week a young man, Grayson Cole, came in for a routine physical. He mentioned being referred by one of my regular ‘patients.’ I never know how much first timers know. Obviously, Zac would not have sent Grayson to me if he didn’t think the young man would be a good fit. I pegged Grayson as being straight, though. At least, he thought he was. Fucking any young man is a pleasure, but there is something extra special about taking a straight boy’s cherry. It’s no accident that gay men like anal sex. A lot of them, anyway. The prostate is a powerfully sensitive organ. Straight men have them, too, though. Recently, they are beginning to discover that. It’s no longer taboo to slip a finger in there. Some men are even opening up (no pun intended) to the idea of pegging. That’s letting a woman fuck them wearing a strap on. Everybody’s sex is their business, but a strap-on is not a man’s dick. There is nothing like the real thing.So, yeah, Grayson had at least a bit of notion that he was straight, but I wasn’t going to let that get in my way. These days, more and more young guys are more and more flexible in their identity, and I’m happy to take advantage of it and press my luck. Whatever label he wants, Grayson is a prime cut of collegiate beef cake. Blond, blue eyes, fit body with a broad chest and a respectable size dick. Not as big as mine, but few are. He was just in my office for a physical, so he was feeling fine. I was about to make him feel even better.Like I said, I’ve spent a lot of time building my practice. Part of that is knowing just which buttons are effective in getting my dick into a young guy’s hole. With Grayson it worked like a charm. It took thirty minutes or so. He didn’t come in looking for it. Once I was balls deep and plowing him open though, he was just laying there with his legs spread wide, giving up his hole and taking my load like a good boy.He was wobbly on his feet walking out, but he had a smile on his face. I was ready for seconds, but there was no way of knowing if he would be back, or if he was a one and done. Even if I give them the best ride my dick can offer, a lot of straight guys are like, “That totally blew my mind, but I’m straight, dude!” I was thrilled when I got a call from Grayson.Like most of the straight boys, but some of the gay one’s, too, he was embarrassed to just ask for what he wanted. He needed to see me right away for a “sprained ankle.” Anybody, let alone a young athlete, with a sprained ankle puts an ace bandage and an ice pack on it and camps out on the sofa. If they call the doctor, they say, “Can I come in? I think I may have broken my ankle.”“Sure thing!” I’m not going to argue that hot young stud out of giving me another chance at his blond bubble butt. Sure enough, by the time he got to my office, his foot wasn’t even swollen anymore. If it ever was. I looked him in the eye and called him on it and he folded. I decided that I should up the stakes a bit and get out my ultrasound machine.It’s amazing how many young guys can get pounded hard and bred deep and still not admit to themselves that, “Yeah, I just dropped my drawers, spread my legs and got fucked like a sorority slut on Saturday night.” Even while they can feel my cum leaking down their leg. They call that cognitive dissonance. My ultrasound machine is one way to break down that denial, though. Once they turn their head, look at the monitor screen, and see the silhouette of my cock driving up into their guts, they know.Grayson was one of those guys. I told him we were going to do something different. I don’t think he had ever heard of ultrasound before. If he had, it still blew his mind. His eyes were glued to the screen, but I have to admit mine were, too. The sight of my cock pounding a boy’s prostate into submission never gets old. Before I bred him, I made sure I fucked a load out of him. He can’t tell himself he didn’t like it with his own cum on his hand. Before he left, I told him that next time he doesn’t need to lie. He can just tell me he wants some more dick. With or without the ultrasound machine.
