Give in

"Please Master break my pussy, I want your dick so bad" you beg him. He smiles and kisses you deeply as he spears you on his 14 inch dick. You moan into kiss as you instantly start cumming. He pounds away at your swollen pink pussy. You cum again and again as he picks up his pace. He holds you tight as he pounds you and you wrap your arms and legs around him to pull him deeper into you. He stops kissing you and you try to tell him harder but you moan so much that you cant pronounce words, only more moan.

Your suddenly hit by a super intense orgasm that nearly knocks you out. You don't know it but he planted a symbol inside your womb marking you as his pet for the rest of eternity. You start to lose time as the fucking and cumming continues. He never seems too cum but every few seconds your shaking and gasping for orgasm after orgasm. You've cum so much that your cum is pooling under you.

After a whole 24 hours of fucking, cumming, fainting and doing it all over again he finally slams deep into your womb and starts shooting into you Squirt Squirt Squirt Squirt Squirt. Your belly is so bloated from his cum that you look 9 mouths pregnant. Any sane person would be cry and yelling but you have a smile of bliss on your face. He kisses you a final time, then gets off of you. You watch him as he starts too shake. He starts to form two heads and after over a minute he has formed a complete twin that stands next too him.

"Have fun my pet" your master say too you. He leaves the room and his clone climbs onto the bed on top of you. He then slams his dick back into your cum covered swollen pink pussy and starts to pound away. You are forever stuck in that room full of demon cum. Your mind is gone and the only thing left of you is your withering body that's stuck in orgasm. You have been mind-broken.
