Nighttime Experimenting

“So Tonks…We all know that you’re a metamorphmagus, what say we have some fun with that?” Ginny grinned, pulling Tonks into her bedroom and locking the door. Ginny currently shared a flat with Hermione as both of the young witches had recently finished school and didn’t know where else to go yet. However, Hermione was currently off at the Burrow visiting her boyfriend. Yes, Hermione and Fred finally realized their feelings for one another and had been going out for the last six months.

“What kind of fun are you talking about, Gin?” Tonks asked, sitting down on the bed and shifting her legs to intentionally show more skin. The two weren’t exactly going out, but they did like to fool around, especially when one was horny and couldn’t get any. For the most part, both were into having sex with the male variety, but mixing it up every once in awhile seemed to be fine with them.

“How far have you ever tested your morphing abilities?” Tonks had generally shaped her features to Gin’s likings when they were fooling around, and so that neither would feel awkward later on if the face was the same.

“Tested my abilities? Well, we all know I can make it look like I’m an entirely different person…” She said slowly, not knowing where Ginny was going with this.

“Well, yea, we know that. But…have you ever tried to change your sex?” Ginny asked with a hungry look in her eye.

Tonks blinked, trying to make sure she heard the young woman correctly. “Change my sex…?”

“Yea! I mean, with your morphing abilities, haven’t you ever been the least bit curious to see if you could?”

Tonks rested her hand on her chin for a moment, pondering over this idea. “No, I hadn’t. But now that you brought up the idea, it sounds like a smashing good time!”

“Well, have a go!” Ginny encouraged cheerfully.

Tonks concentrated, looking determined to do this to please Ginny. Her shirt got baggy as her breasts slowly shrunk into nothing. The girl went over to Tonks and slowly helped remove the shirt, and got her first look at the newly sculpted male chest. It felt good when Gin placed a hand there and softly flicked at her nipples.

“Mmm, Gin, that feels great!” Tonks moaned softly as she looked down to see Ginny working on her flat chest. The sensations only lasted momentarily as her lover backed up and sat down in the chair across from her.

“Ok Tonks, time to see if you can do the other!” Gin exclaimed, licking her lips in excitement.

The woman looked unsure, but spread her legs slightly, letting her skirt hang loosely over her. She had a look of utmost concentration as she tried to swap one sex for the other. Slowly, she felt her panties get a little tighter, and a small bulge form in the middle of her skin. Ginny ran over and lifted up her skin, meeting the lump under the silk panties that Tonks was wearing. She slowly ran her fingers around the area, trying to invoke a reaction, which wasn’t difficult and soon Tonks was moaning in delight. Ginny slowly removed the panties, wanting to see the flesh that her lover now possessed, although, she was disappointed when she saw- Tonks was only about two inches long and lacking testicles.

“Is…that all?” Ginny asked, trying to mask her dissatisfaction. The small penis started to deflate from being rejected. It looked like it was shrinking back down to a clitoris. “Well, try again! It must be hard to change a vagina to a penis!”

Tonks smiled lopsidedly and looked down at her completely female bits. She stared at her clitoris and pictured it getting longer, and was surprised to see that it responded. The head pushed out from the hood, increasing in length and also width. It soon reached the length it had previously, but Tonks kept concentrating, enjoying the feelings that it brought about. It kept pushing outwards, and soon it reached about four inches while soft.

“Um, Tonks? You’re still missing something,” Ginny teased, pointing at the entrance underneath Tonks’s new respectable penis. The woman flushed bright red, and placed a hand to the area, only to be met with the familiar wetness that her slit held. Once again she concentrated hard and was able to feel as the folds puffed out and melded together, swelling outwards. She could feel as the two testicles dropped into her scrotum, completing her sex into that of a male.

“Oh, so wonderful!” Ginny cried as she took the momentary limp penis in her hands. It didn’t last long before Tonks became erect and her member stood out at a proud eight inches of manmeat. Ginny’s hands left for a moment, and Tonks looked on in amusement as her skirt was lifted up off her crotch by her erection.

Ginny stood in front of Tonks, looking seductive and slowly running hands down her curvy body. The older woman whimpered as she felt little drops of pre-cum drip out of her throbbing member, creating a wet patch on her skirt. Piece by piece, Ginny’s clothing came off and fell into a heap on the floor, until she was standing in nothing but her black silk panties. She moved over to the bed and settled down so that her back was propped up against a couple of pillows, and her legs beckoning. Tonks couldn’t resist and moved over next to her and softly traced her fingers down Ginny’s wet panties, feeling the heat radiating.

“Take them off,” Ginny breathed in Tonks’ ear. The material slipped down Ginny’s creamy white legs, and exposed her heated sex. Ginny spread her legs, allowing Tonks access to her core. Gently, Tonks ran a finger down the folds, feeling the wetness that Ginny was already producing. She moved her head down and tentatively placed her tongue on her clit, causing the red head to moan in delight. Tonks brought her tongue back out and started at the bottom of Ginny’s lips and traced up, teasing the girl mercilessly as she worked up to her engorged clit.

“I need to feel you inside me…” Ginny moaned, spreading her legs even further. Tonks couldn’t help but be intoxicated by the girl. She carefully placed her new penis at Ginny’s entrance and teased her for a moment by running her leaking dick up and down the folds.

“Now!” She cried, really needing the older woman inside her.

Tonks readily complied and little by little pushed inside the tight flesh. She groaned in pleasure as the walls tightened against her pulsing cock. Once she was sheathed entirely in Ginny, she started to thrust in and out of the sopping snatch, sparks of pleasure coursing through her body each time Ginny clamped down with her muscles.

“Engorgio!” Tonks muttered, pointing her wand at Ginny’s clit and watched it puff out to about three times its original size. She placed a hand on Ginny’s now large clit and stroked it, feeling it get even harder under her ministrations. Whimpers of pure pleasure escaped Ginny’s lips as what she felt grew in intensity with the growth of her sex.

However, it didn’t take much longer for Ginny to be pushed over the head by being assaulted by being both penetrated and rubbed at the same time, and threw her head back as waves of pleasure racked her body when orgasm hit. Tonks grinned and continued thrusting in and out, still relishing at how much bliss she felt with being inside someone. She felt her cock throb even harder, balls pulse, and then all the sudden, her dick twitched and started pumping cum into Ginny’s waiting sex. She gasped with how different a male orgasm felt, and slumped down on Ginny, softening penis still inside her vagina.

“That…was amazing,” Tonks breathed, her pulse still quick from their excursion.

“I’d have to concur,” Gin agreed, giving the woman a tight squeeze. “What spell did you use? I couldn’t hear it, but damn! Whatever it was, it made things so much better.”

“Heh, just a different use of the Engorgio spell than most would think…” she smirked as she climbed off of Ginny and slowly pulled out of the girl, leaving her with a nice view.

“Whoa! That’s huge!” The red head exclaimed as she caught sight of her swollen clit. “It’s like my own mini dick.”

Tonks raised her wand to remove the spell, but Ginny stopped her. “I like it, don’t remove it, please?”

“Whatever you say…” Tonks grinned, knowing that this could only lead to more romps soon enough.
