He attempts to get the heir

He loosens the chains on the wall, so you to fall on the floor, but keep you chained. The chains are loose enough for allowing you to sit there, but barely allow you any other move. You look up at him as you sit there. You're very wet at the idea of getting chained and even more about the idea of being **** to get pregnant... But you never thought about **** before.

He exposes his big cock and forces your legs open, exposing your wet pussy.

"It seems the queen is excited about her son giving her another baby."

Then, he introduces his big cock in your pussy and starts fucking you roughly. His cock is much bigger than his father's ever was and even most of your lovers got smaller ones. It makes you wish to keep him as your lover... but you remind yourself that, in fact, you're now his lover and toy.

His orgasms and you feel a big amount of cum filling whole your womb
You're pretty close to cumming - what he notices.

"I don't care about your pleasure mom... but I'll allow you to get your orgasms." he says giving you a sadistic smile
