Henry, now Henrietta's, flushed, feminine face looked backwards at Joan with a lustful look. Her gaze trailed down to Joan's cock, and she began to shift her rear around, rubbing her shapely thighs together as her new tail raised, presenting her need. She then spread her legs and pushed her ass up in the air, giving Joan an open invitation. Her pussy dripped with anticipation as her tail swished, fanning the scent of her pussy around the room.
Happy to oblige her soon-to-be mate, Joan could also feel her tail swaying in anticipation as she gripped Henrietta's generous bubble butt for leverage, positioning her monstrous member between her rear legs. Feeling the bulbous tip of Joan's cock rubbing against her inner thighs, Henrietta pushed out her ass, happily accepting it.
Joan's cock had gotten so huge that it was hard to get it into her pussy, but managed to after a couple of tries. Her first thrust buried her cock six inches into her tight pussy, and the next jerked Henrietta's whole body forward. Henrietta could not not physically take the entire length of Joan's cock, with the top third of it not able to enter her waiting pussy. Henrietta squeezed her eyes shut and moaned loudly as she experienced her first fuck as a woman, her four huge tits swinging heavily with each of Joan's thrusts.
Joan began stroking her long, rock hard nipples and milk shot all over Henrietta's back as she started fucking her in earnest. Henrietta moaned and screamed, urging Joan on, her pussy squeezing Joan's cock. Fur began growing in light patches between Joan's tits, and in her armpits. It also sprouted from her arms and legs, but everywhere else remained hairless.
Henrietta bucked her hips back and forth, feeling Joan's immense cock slid in and out of her as she bleated in pleasure. The fluttering of Henrietta's pussy pushed Joan to the brink, and they both cried out as Joan came, gushing what felt like gallons of cum into Henrietta's eager pussy.
Joan dismounted, her slick cock sliding out of Henrietta's pussy and falling between her legs, dangling and slick with Henrietta's juices as cum dripped onto the floor beneath her.
"Good girl," she said and patted Henrietta on the flank as the electric barn doors opened into the massive pen where many goats could be seen grazing and some were asleep.
"You will make a fine addition to the herd. Go on, join them." she slapped Henrietta's ass as she nodded with a smile. Her mind was now only focused on her baser instincts and wasted no time in joining the herd. Joan went to the edge of the door, watching in anticipation as Henrietta began her new life. With her four milky tits she could feed many of the young and her tight pussy would make many of the herd males happy.
Henrietta trotted over to the trough with animal feed and began eating from it freely. She lifted up her tail and urinated, and this seemed to turn on one of the male goats as he crossed over from the other side of the pen and mounted her again and again. She paused her eating as feed fell from her womanly lips, moaning as her tongue lolled out of the side of her mouth in pleasure.
Watching this was making Joan get hard all over again, then all of a sudden, the collar around her neck beeped and before she knew it, she was shocked with 50000 volts of electricity and everything went black as she fell to the ground.
