"..to try mounting her." Mike had been wondering what it would feel like to use the enormous stallion's equipment. If the filly was in heat and also interested in him, why not try mounting her?
The boy grinned. "Here, let me help you out a little." He went over to a side room and came back with a clay jar. Scooping some dark cream out, he reached under Mike's belly and applied the warm, thick paste to Mik'e shaft. "That will lube you up, and you'll be way more priductive." Warmth spread through Mike's penis and spread to his testicles, and he was amazed by a sudden increase in sensitivity. The boy moved in front of him and reached up to smear some of the cream across Mike's nose and mouth. Almost instantly, Mike was aware of a powerful, seductive odor. The filly!
Opening Conner's gate, the boy chuckled. "I figured you could use a little help. Scent is a big part of sex for horses."
Mike's eyes widened as the filly's signals suddenly connected in what must be an equine center of his centaur brain. Lust swelled, and all he could think about was mating with the female. The boy backed out of the way as he moved intot he stall and nosed at the swollen black lips that wlecomed him.
The boy watched as he closed the gate. The centaur was oblivious to everything now, including the changes the cream had made to his face. His features were a cross between equine and human, nostrils flared and thick lips working over large, flat teeth.
Mike pressed against the mare, then pushed and jumped, sliding over her back. His arching, rigid shaft missed the welcoming opening the first time, but he found it the second thrust. Sexual pleasure overwhelmed all other thought, and he drove in deep with the instinct and desire of an animal.
