This is a custom clip and I can make one for you too! Just email me at emmasecretmln@yahoo.com or send me a PM) I was cursed over 300 years ago for treading in the forbidden valley that only gods were suppose to walk. I was riding my favorite divine stallion Argo when he felt the pull to go to his master lord Resheph the God of War, Thunder and s. He cursed my step-father a beast forever to guard the forbidden valley from intruders. The divine stallion needed a mate and that was now my job to hold his divine seed. Lord Resheph warned me to not let his seed be released until he has gave me his entire load.  I would have immortality but if I didn't for fill my duties I would then turn into a beast myself. I will know when it is time to perform your duties when you begin to grow horns beginning your transformation into beast. Well the horns have appeared and time has come to hold the divine seed
