"Well... How about... how about you and I swap sexes?" Haley said.
"What?" I looked at her, confused. "But I thought you were a lesbian. You want to be male?"
"No. Not exactly. I've heard you men wouldn't like being women. I'm meaning more... just a cock swap." She giggled.
"A cock swap? But Haley, you don't have a cock."
"Exactly." She laughed. "I mean you and I swap genital genders. You get a pussy, I get a cock." She smiled. "Come on. Give it a shot. For me please?"
I stared at her in surprise, not sure how to handle this. It was an interesting idea, and it certainly wouldn't be a major change. Oh sure, I'd lose my member, but I'd still be male over the rest of my body. "Um... Sure."
"Thank you." She wrapped her arms around my neck in a tight hug.
"Alright. Alright." I gently held her. "I wish we both we completely naked."
Haley gasped as she suddenly felt her breasts pressing against my chest, then blushed. "Hey! Warning me next time."
"Heh, sorry." I chuckled. "I was thinking you wanted to watch the changes happen and not just feel it."
"You thought right." She said, smiling.
I looked down at our bodies, and got aroused at her pert breasts. My member was already starting to get hard. "Here goes nothing." I sighed. "I wish for Haley and me to swap genital genders."
Haley and I both gasped at the same time as it felt like millions of tiny hands suddenly rubbing at out crotches.
My balls started being rubbed, moving around slowly as they began to slide into my body, the skin of my scrotum stretching and flattening against the base of my shaft. It looked odd to only see the member and nothing behind it. Before I knew it, the hands too the tip of my member and started pulling on it and making it inverted. It felt like I was getting an erecting, but in the opposite direction.
I reached down and gently rubbed my shrinking dick, and felt the effects speed up. The skin folded in on itself, moving closer to my body until my crotch was completely flat and bare except for a tiny hole that was my dick. In intense pressure was suddenly felt as the hands began pushing around inside me. Watching in fascination, I saw the tiny hold starting to stretch from the front of my crotch down between my legs as the hands rubbed and massaged the flesh around the forming slit, causing it to slightly swell up into a set of vaginal lips.
The pressure turned inward, and I placed my hand on my abdomen. I could feel things moving around to give room for the new organs, feeling the tunnels and tubes forming inside me. The greatest of pressure was felt right in the middle, where I assumed my womb was, as it got warm. The pressure and warmth continues, getting bigger and more intense as it grew the inner most female part before coming down and stopped, finishing my transition.
Haley, at the same time I was losing my dick, was moaning and rubbing her crotch as similar feeling hands were pushing from inside her body to the outside. Everything she was feeling was in the exact opposite order of what I felt. The warmth in her womb faded as the various tubes and tunnels were vanishing. Her slit stretched and pulled, pulling away form her crotch as it closed up, becoming a small hole at the tip of a thick and long tube of flesh, a mushroom head forming around the hole. Everything felt different down there for her. Rubbing didn't give the same sensations as before.
A gasp escaped her lips as she felt the skin at the base of her newly formed shaft began to expand and swell up. Slowly two balls, which had been her ovaries, moved into place, having been changed into their proper male equivalent, and finished her change. She let out a moan as she gently ran her hand up and down the length of her member, which ripped my attention from my tender new slit.
I looked up at her shaft, and blinked in surprise and embarrassment at the sight. "T-that's bigger than mine was." I gulped. Her shaft was bigger, longer, and thicker than mine, and her balls were the size of soft balls. Another surprise hit me as I felt myself get wet at my new equipment. I wasn't into dicks, but it appeared that my changed sex didn't know the difference and only cared about the opposite.
Haley was smiling at me. "It works. I can't believe it works." It was very easy to tell she was aroused by her new body part.
