Mike was tempted, but what would happen if he mounted the mare? Sex seemed to change him more, or had back in the stable. He shifted as the twins continued to rub him, keeping his shaft erect and testicles throbbing. They were definitely making it harder to resist the mare's scent. Caleb watched them with a grin, then asked "You know, if you don't want to play stallion, my brothers can take care of things for you."
That was certain, Mike thought. The boys might be young, but they knew how to keep a stallion aroused. He twisted around to grin at the twins. "OK, you guys. Take care of me."
The boy with his hands around Mike's cock looked amazed. "Really!? I didn't think you'd want to give it all up."
That puzzled Mike. "Give what up?" The boy's grip shifted and he felt the small hands squeezing his hafts near the middle. At the same time, the other boy slid one hand under Mike's heavy ballsack and gripped the very top with his other.
Caleb was watching and winced as Mike felt a very strange sensation of heat, a sharp but quick pain, and then a wave of confusion. The twins stepped out from under him, one holding what looked like a thick black sausage, while the other held a leathery bag with large rounded objects. "What are those?" Mike asked, feeling he should know but unable to identify the items.
Caleb chuckled as the boys brought the objects to him. "The cock and balls of a Shire stallion. Very useful if you want to have sex with a mare."
That puzzles Mike even more. "Sex? What is that?"
"Nothing you need to worry about. How about we go back to the pasture with the geldings? I think you will be really happy there."
