2T4U/Jack/Bandit on the nature trail/Go off the trail and just butt-fuck Bandit
Your cock is so hard it's uncomfortable to walk, so you turn off the trail into a clearing where you shouldn't be disturbed. Once alone, you drop your pants, free your straining cock and give it a few strokes, which feel good. You let Bandit off the lead so he comes over to investigate and you get him to give it a lick.
"You like cock do you boy," you growl as he slurps his rough tongue over your knob-end. Now it's out in the cool air, and even with bandit's stimulation, you still seem to be a way off climaxing. What you need is a hot wet hole to fuck. Bandit gets bored and turns around. His tail is up and you look at the tight pucker of his ass and a thought come unbidden into your head.
You reach out and grab his hips to pull him closer. He doesn't seem to mind, even when you poke his ass with the head of your stiff cock. "Maybe this isn't your first boy on boy action, but it's a new experience for me," you say as you wipe your precum-drooling cock around his brown starfish. You line your cock up and get a firm grip of his hips, then you start to push. Bandit is a big strong dog and if he had really wanted to, he could probably got away, but moments later he has seven inches of teenage cock buried in his ass.
It feels really great as you start to fuck him and you reach down to find that his own cock is out of its sheath, so as you fuck his ass, you wank him at the same time. It doesn't take long before you are pumping a load of cum into his guts and as soon as you are done, you pull out. Bandit is not so happy as he is left with a stiff cock and nowhere to put it.
