Ben led Jennifer upstairs to his bedroom, where they immediately began to make out. As their lips pressed against each other and their tongues danced, Jennifer's hands took his and led them down to the bottom of her strained blouse. His hands clenched the fabric and slowly brought it up over her growing breasts, which barely fit in her C cup bra. Now that her chest was revealed, they could see that her fur coat extended above her private region to end just below her navel.
Once the blouse was over her head, Ben brought it to his nose and took in the pheromones. "Why don't you get your high right from the source?" Jen asked as she pulled him closer and allowed his nose to explore the most potent pores on her upper body.
She rubbed her body against Ben's as she continued transforming. Her hair steadily crawled down her back and her lower body was now completely goat-like. Her ears formed points and grew out from her head, attaining a short coat of brown fur.
With a snap, Jen's bra admitted defeat over her enormous breasts. The two were startled out of their fixation and shared a quiet laugh.
"It's your turn," she said. She helped him out of his football jersey and shirt. As she worked on disrobing her partner, fur sprouted from her wrists and spread almost to her elbows. Soon six-inch hairs as black as those on her head were flowing across her forearm, long and soft. The same type of feathering formed at her ankles, and grew down to reach the floor and cover her hooves.
Ben undid his jeans and they collapsed to the floor. As Jennifer wrapped her arms around him, she nudged him over to his bed. They fell together onto the mattress and continued to explore each other. Ben ran his hand across her bottom to find a long ebony tail was growing from her buttocks.
Ben gently slipped on top of his mate, presenting his underwear. Jen peeled back the elastic and slid the briefs down his legs. Her fingers were fusing together in pairs, creating two thick fingers and a thumb on each hand with large black fingernails.
As Ben slipped down her body to be eye-to-eye with her, he saw a mass of freckles splash across her round face.
They began to mate. The sensation of Ben's organ inside her new goat vagina was more ecstatic than anything Jen had ever felt. Their bodies united passionately, glistening with sweat and scented by Jen's aroma. Her dark locks continued to grow, now long enough to reach her tail. The tendrils spread across the bed in a web of curls.
As she neared climax, she felt a sharp headache concentrated on her forehead. Two sharp points burst out of her freckled skin just below her hair line. With each thrust of Ben's member, Jen screamed from both the pleasure of him, and the pain of her new horns. Each thrust elicited a scream, each scream pushed the horns out inch by inch. They were the same ebony color as her hooves and segmented with bumpy rings forming the divisions between segments. The protrusions curved toward the back of her head, reaching eight inches in length before they stopped growing.
Ben exploded into her, sending a cascade of pleasure through her body to snuff the pain her horns had caused. The two lovers stayed locked together for several moments, panting from the exhilaration.
Slowly and reluctantly, Ben sat up. His eyes took in all of the stunning, shapely and magnificent figure of the naked satyress.
