The sex curse?

Sam had a good life but he hated all the rules he had to follow. As the prince his father told him that a lot of people looked up to him. Sam was the next in line for the crown but after that his brother Shane was was in line for the crown. It was just the three of them outside of the servant’s. Sam had a hard relationship with his brother because as twins both had the right to the crown. The king went by birth order of that day and that put Shane in line after you. Your father never really looked at you though and things you heard whispered behind closed doors never ceased. You knew your father was hiding something from you but what that was the question. You were trying to figure out how to ask your father that question when a servant came to your quarters. What is it you asked the young servant in a tart tone. The servant replied with your father wishes to meet with you. Sam knew that wish in that sentence meant his father was telling him he had to meet with him. So Sam went to meet with his father in the royal hall. Sam wondered what he did wrong this time. Was it about the maid he fucked this morning if so couldn’t the old man let it slide after all it was Sam’s birthday. Sam didn’t have to obey his father anymore he is 18 what more could Sam ask for. Sam arrived at the royal hall to find his father naked having sex with the same maid Sam had sex with that morning. The king saw Sam. Oh my the king said your early. Sam looked at his father then at the maid in a hazy state. Well this is not going to be about the maid. Sam understand that after seeing what was happening. The king dismissed the maid but told her to come to his room later. Sam looked at his father. Sam I have asked you to meet with me because of a matter of importance. Sam told his father to just tell him and skip the theatrics. The king was shocked but replied well ok Sam don’t say I didn’t warn you. Sam looked at his father with a mock concern. The king started out Sam first I must say your cursed or well with you well you might find it a blessing of sorts. Sam looked on in fear. You see Sam after your birth we had a celebration for you and your brother Shane. Oh don’t remind me Sam said. Well you see at that celebration you were cursed by a centaur. A What Sam said. Oh never mind the king said. The thing is the curse couldn’t activate tell today your 18th birthday. The curse is that any man that ask’s you to have sex with them whatever spices they may be you agree to it and are always the submissive. To make matters worse you can now bring children into this world acting as the one that cary’s the child. Sam now had true fear in his eyes. There is a way to brake the curse but it will hurt. Sam looked at his father some of the fear gone. What do I have to do to be rid of it father. First you must have a child with one of lowly birth then one of grate Rich’s. Then and only then can your true journey begin to find the dragon that the centaur worked for. Once found you must offer yourself to the dragon as his sex . You will be free of the curse but be bound to the dragon tell it sets you free. But first you must find that dragon. Sam looked like he was going to puke then die. Then do the whole thing all over. Sam asked his father what am I to do. The king looked at his son with sadness. Then replied I can’t tell you Sam it’s your choice but make no mistake your choice will change your life. You must make your choice by sunset tomorrow I’m sorry. Sam’s jaw dropped and his father left the royal hall leaving Sam alone grappling with a choice. A choice Sam knew would change his life.
