Rachel reached up to touch my shoulders and pull me down into a pasionate embrace. As her hand touched my skin she shreaked!
Fumbling she turned on the bedstand light. My eyes closed as the hundred watt bulb glared in my face.
"OH GOD DEAR, YOUR A BRAHMA BULL! Rachel screamed in terror.
As the eyes cleared I had to agree I was changing into a big Brahma bull. Even as we mated the chage raged on and my arms were completly changed to forelegs and cloven hooves of a bull calf size.
Kneeling on the bed my bull cock dripping of semen swayed in the air erect and very pink. My balls lay in a furry sack on the bed as I peered behind to see feet now more bovine than human.
"His curse is real Rachel, I becoming the bull he said I would!"
Rachel swung off the bed and stood beside me. I moved my stiff and bulky body till my forehooves' stood on the bed and my rapidly changing hind legs stood on the floor.
I stretched my stance which let my ball sack hang free to swing. My bull sheath hung out and forward clung to my belly. This movment made my erect pink cock swing and stiffen again.
The sexual feelings, lust for deep thrusting sex made me strain my neck upward and Rachel stepped back as the change finalized. Head to tail back to hooves I stood a fine muscled form of a bull calf.
Rachel took the moment to enjoy my erect self and touched it as she opened her mouth for a oral delight. The feelings came as a dam burst full on sexual lust. In a minute I unloaded in her mouth what had to be a quart of bull semen.
Coughing and spitting she stood up. "Damn you, Oh dear look at you! You've grown bigger!"
Indeed by having sex again my bull self matured.
