As soon as Ty left the room June reached with both hands for the shrunken and drastically changed Mark. “Ooh!” June said, seeing the little horse squirm in her grasp, “Look at how nervous he is!” She grinned and gently began to stroke Mark’s chest with her index finger, resulting in the muscular equine settling down and feeling a bit more relaxed. June began to gently fondle the tiny creature, feeling out his tightly toned and defined form, brushing her fingers through his luxuriously soft and smooth hair.
Already excited, it took June little effort to feel horny again. In no time her fingers were tracing her new friend’s large penile sheath, squeezing his tight bottom, and generally teasing his body into arousal. Mark neighed in delight, loving the feeling of the giant woman getting provocative with him. A few gentle rubs of his sheath and the large organ within spilled out against his chest and thigh, starting to rapidly inflate with blood.
June took her finger again and while still holding Mark in her hands she gently brushed his semi-hard cock from base to tip very slowly and deliberately. Mark closed his eyes and groaned, his sensitive organ still tender from Ty’s earlier attentions. It hardened up to it’s full length while June rubbed it, swelling to enormous sizes only an animal could reach, stopping as thick as Mark’s fist and long enough to dangle just above his neck while he sat on June’s cushiony breasts. “Wow!” June said in even more excitement, “would you look at the size of that thing! I guess they don’t say hung like a horse as a joke!”
Mark smiled proudly, putting his own little hand against the tip of his cock to support it as June continued to massage it with her finger. In no time the tiny equimorph was in the throws of passion, having another masturbate him was very exciting! His cocktip flared and his body warm and comfortable in June’s grasp, he felt ejaculation coming. The promise of growth made it all the more exciting for him, and Mark was eager to get bigger. He suddenly whinnied in orgasmic delight and poured seed from his cock, soaking June’s hands and to a lessor extent her breasts as the foot tall animal shot load after load of semen.
June watched in sudden amazement and then wonder as Mark suddenly gained a whole inch in height as he finished ejaculating. Gasping for breath and his body tingling powerfully, Mark barely had time to recover before he felt June’s tongue touching his fur and then his cock, licking at his member, which was still rock hard. Mark tensed and let out a terrific cry of raw pleasure, and with a sound much like gurgling water, his testicles instantly refilled like balloons, pumping up tight with reproductive juices.
