Mary breeds Rasha

The voluptuous demon leaned back on one of the nearby sofas and spread her legs in preparation for the debauchery about to happen. Her ripe pussy gleamed in the dim light, beckoning Mary like a pot of jewels.

“Come on dear, we haven’t got all day!”

Mary looked down in horror at the monstrosity bulging from her legs. The penis jutted like a heavy rod of iron from her crotch. She seized it with both hands as if to confirm that it was truly there. She immediately regretted doing so, as a rush of unholy lightning rushed up the bulging member.

“Oh no no no no! This can’t be real! I can’t have a d-d-d-ding dong!”

“You can and you do! Now come along my well hung servant. It is time to perform your duties to your mistress.”

“No, this is wrong! This is…evil! I won’t do it!”

Rasha raised an eyebrow and sat up, “is that so? Are you reneging on our oath.”

“This was a mistake. I don’t want this. Please reverse this.”

“I couldn’t reverse this even if I wanted to. After all, you cannot unbake a cake. Now come here and make your mistress moan!” Rasha squeezed her bulging tits together to emphasize her point.

“No! No, please no! I don’t want thi—wait, what’s happening?”

A deep ache throbbed in Mary’s newborn testicles. Instinctively, she cupped them and then gasped as she felt them swell even larger, growing into small melons.

“Ah! They hurt!”

“Your body senses me. Your sperm production is in overdrive right now. You need a release, darling. Let me give it to you.”

“No, I won’t!”

But even as Mary spoke these words, the achy pain grew worse and worse. She felt like she was going to explode. Meanwhile, her penis had sucked up so much blood that she was starting to feel light headed. She could barely think straight.

“No! No! This is wrong! This body is wrong! Sex is, ngh, wrong! It’s all wrong!”

Rasha moved in a blur. One moment she was on the sofa, the next she was right in front of Mary.

Mary winced, preparing for a blow from her disgruntled mistress, but what came instead was far worse. Rasha planted a kiss on her lips that was so soft and sweet that she nearly lost her mind.

A hand gently caressed Mary’s heavy balls, sending a forbidden tingle through the young shemale’s body. Another hand took hold of her throbbing cock and pumped, pumped, pumped.

“Would something wrong feel so right?”

Rasha’s beautiful face was irresistible. Mary’s last reservations slipped away. The animal within leaped out of its cage and went on the attack.

They moved in a whirlwind of kisses and sucking and fondling. Mary practically tackled the demon onto the couch, exerting far more strength than her rail thin, five foot tall body should have been capable of.

“Look what you’ve done to me, you demon bitch! You turned me into a freak! A shemale freak! Now I’m going to make you pay!”

“That’s it, Mary! Make me pay!”

“I’m gonna split you in two!”

Mary took hold of her massive cock, which was so massive it required both hands to properly maneuver, and placed the bulging head against her mistress’s gooey twat. A shiver ran through her as she realized what she was about to do. She was about to fuck a woman with her…her penis! It was so wrong and disgusting and she had never wanted anything more.

“Take it, bitch!” Mary thrust forward, feeling the warmth and wetness encompass her entirely.

“Oh my God! Oh my fucking God! Mistress, it feels so fucking good!”

“Yes, Mary! Pump into me my devout convert! Fill me with that boiling man seed of yours!”

Mary began to pump her cock into her mistress’s pussy in ragged thrusts, grunting and wailing as she did so. She was rabid and uncouth, like a wild animal.

“Fuh…uh…uck! It feels soooo good!”

With each thrust, Mary’s enormous testicles slapped hard against Rasha’s plump behind, triggering a dull, pleasant ache in the male organs.

“Yes, Mary! Embrace the beast! Embrace your manhood and release your potent seed! Breed your mistress!”

“Fucking slut! Your pussy feels so good! So warm and tight! It feels good in my…my…my cock! My big, meaty, manly cock!”

“You’re so close! Now let it all out!”

“My cock…hehe…it’s so big! So powerful! It’s…it’s…”

Thrust, slap!

Thrust, slap!

Thrust, slap!

“I’m gonna…”

Thrust, slap, thrust!

“Explode!!!!!”

Mary’s squeaky voice rose in a primal shriek of rapture as she unleashed a mighty load of her sperm deep inside her mistress’s luscious cunt. In that titanic explosion, the old Mary, the awkward little mouse, was burned away completely, replaced by something ravenous and unyielding. The primordial seed of a beast that could not be contained.
