In His Slutty Mouth

"Come over here and kneel in front of my dick," Tonks ordered Harry. Harry did so involuntarily.

Sniggering, while stroking her new penis with the hand not in Harry's hair she said, "See something you like Harry? Don't worry, you'll get use to seeing my girl cock regularly real soon."

Harry went to question what she mean, opening his mouth to ask, but before he was able to Tonks had started pushing his head down on her girl cock. "Start sucking Harry, use your tongue, swirl it around the head and bob up and down," she ordered.

Unable to refuse, Harry started to swirl his tongue around the head of Tonks' girl cock while sucking and bobbing up and down on. He was blushing up a storm, while she was moaning out to him, "Ohh, that's a good slut. You must have been born as a cock sucking sissy to have these skills."

She grabbed onto his head with hand with both hands and started to slip her penis further into his mouth. "Harry, you're such a little whore, you don't even have a gag reflex," commented Tonks as she groaned and was able to push more cock into her boy toy's mouth pussy.

As she began picking up the speed she was thrusting into her sluts mouth, he started going, "gluck gluck gluck," as he deepthroated her girl cock.

Finally shoving her penis all the way down her sissy's mouth Tonks was able to feel his lips moan around the base of her cock.

Pulling her girl cock out her toy's mouth, she slapped him on the face with her cock as he tried to recover from being out of breath. With her penis flopping on his face she told him, "Tell how much you love to gobble my girl cock like the sissy slut that you were born to be!"

"Big Sister Tonks! Ohh, Big Sister," Harry moaned trying to get his breath back still, "I love being born as a sissy slut that gobbles your girl cock!"

"Good boy, now I'm going to fuck that throat pussy of mine so hard!" she shouted while sticking her whole cock down his mouth in one go. Tonks only speed up continuing to throat fuck her boy toy faster.

"Gluck gluck gluck gluck gluck," Harry continued to moan as Tonks fucking his face, spittle and pre-cum dripping all down his clothes and face.

"That's it Harry, I'm almost going to cum, when I cum down that throat of yours, your going to cum as well," Tonks ordered.

"Ohhh, uhhhhh," she moaned as she held his mouth to the base of her cock as she pumped her baby batter down his gullet.

When she finally finished depositing her load in the stomach of her slut she pulled out and let go of his head causing him to fall over, leaving his face down and ass up.

After ungrowing her girl cock, Tonks pulled her panties back up and gave her slut a slap on the ass. Relishing in the eep he let out she gave him a final order before leaving for the night. "I want you to find me tomorrow after dinner on the first floor, I'll give you an in depth tour of the dungeons," she chimed with a wink before leaving.
