When I told my girlfriend, I thought she would be angry. Much to my surprise, she was glad. She had always wanted to do a boy in the rear end, but was always too embarrassed to ask. Once I requested her permission, it was like I gave her a license to engage in her fantasy and mine as well!

The day she got it, I wanted to try it out immediately. It was really good at first, but over the next few months, I got tired of it. I wanted something real. Our only problem was both of us were not into swinging. She didn't like the thought of me being with someone else any more than I liked the thought of her being with some stranger, even if we were there to watch or participate. What were we to do?

Then my girlfriend was on the Internet one day. She found a site where they advertised these new pills that would reverse the effects of one's sex! And the process only took a few months! The thought that I could have a vagina for a short time didn't entice me so much, but the thought of a big huge cock between Leslie's thighs turned me on so much I figured we had to try it.

Because of our work, we only left the house once in awhile, so we realized we could do this and if we did it right, no one would notice we were taking this stuff. We sent away for it, eager to see what the effects would have.

Days later we got our magic pills in the mail. During the waiting time, I had thought maybe we were getting scammed. There's no way these would work.

We opened the box and found two large bottles inside. One was pink and the other was blue. The instructions said to take one pill a day.

"Who needs instructions?" my girlfriend laughed, "we should just take a handful of them and see what happens.

By now we were severely horny. We hadn't had sex since my girlfriend told me she wouldn't have sex with me unless she was fucking me in the ass with her own penis. The idea got me so hot, I threw caution to the wind along side her. I took a handful of the pink pills and she took a handful of the blue pills.

Instantly we tore off all our clothes. She got a fabric ruler and measured my cock. It was a humble six and a half inches. We went to the bathroom. We both have shoulder length hair but just for fun we cut her's short to make her look like a young man. Then we each shaved off each others pubic hair, making us both smooth as silk in our crotches. She kissed the head of my cock which made it stand at attention.

"I just wanted to say good bye to your penis while we make this new exploration." she said.

A few hours later we both began to feel funny, a little dizzy, and a little giddy, like we had each drank a bottle of wine. She stumbled to grab the fabric ruler to see if this was from the pills. She grabbed my penis and jerked it a few times to get it to stand tall. At first she thought I wasn't getting hard, but then she realized my dick had shrank a full three inches! And that's not all; my chest had begun to swell with the emergence of small developing breasts!

Leslie was no different. Her breasts had gone from C-cups to A-cups in a matter of a few hours. Quickly we both wanted to see if her crotch had changed. To our astonishment, her clit had grown into a three inch long penis, the same size as mine now was!

"Oh yeah," she reveled, "this is good but we both know three inches is not enough to fuck your tender ass." Listening to her talk like that turned me on.

"Let's take another handful of pills!" I gasped.

With vigor, each one of us swallowed another handful of magic pills. This time, we were already giddy and dizzy, and we each passed out on the bed in each others arms.

When I woke, I went to take a pee in our bathroom. I had forgot about the previous night for a minute and instinctively reached to squeeze my lizard. But there was nothing there! I looked down to see what was left and instead I only saw large round breasts! I looked at myself in the mirror. My thin muscular body had grown soft around the edges and my crotch was smooth and flat. I spread my legs, expecting to see a vagina, but my cock and balls were still there, they were just smaller than my pinky's fingernail! I quickly sat down to pee; the stream was the same size as my entire penis. I needed to wake Leslie.

"Tristin!" I heard her call out from the bedroom.

I stood up and ran to her. What a beautiful sight she was.

Leslie had become wiry and muscular. Her breasts had completely been replaced with tight firm pecs. Her face hadn't changed but with her hair she looked like a young man. "Check out my cock!" she said, excited.

Between her legs was a full nine and a half inches of uncircumcised man meat waiting eagerly to be enrobed by my ass shaft. "It's beautiful!" I said.

"Time to suck it bitch." Leslie grabbed the base and pulled back the foreskin with one hand and started fingering her asshole with the other hand.

Admittedly, I hadn't yet sucked a real cock of this size, but getting around that obstacle was a task I took with pride. Once her erection was lubed up with my spit, I immediately got up and sat down on it. It was warm and alive and deep inside me! Leslie sucked on my tits as I slid up and down on her cock. I rubbed my tiny penis and balls like a clit but to my disappointment, they had no feeling in them at all. I ignored this as I felt an orgasm building up inside me. Leslie was feeling it too. At the last second, she came and I did something I always wanted to do and pulled her cock out of my ass and shoved it in my mouth! But there was no cum. It was just a clear liquid that was sticky like cum but tasted sweet like the way her pussy had. My ass to mouth treatment turned me on so much that my orgasm followed hers. But nothing came out of the pathetic little thing between my legs. Instead I felt a tidal wave wash inside my guts as I had the orgasm of a life time!

As I lay in her strong arms, her hand cupping my left breast, I wondered how we ever did without these pills. I wondered how long this would last before we turned back into boy and girl again. "Maybe we should take another handful for fun." Leslie said. Her voice had lowered a little. "Yeah, let's do it." I said, my voice was high and light. Leslie reached for the bottles and stopped when her eyes met the label.

WARNING: it said. DO NOT EXCEED RECOMMENDED DOSAGE OR EFFECTS MAY BE PERMANENT! Leslie gasped and read the label out loud to me. I screamed and then started crying. My emotions as a new woman were taking over. Leslie punched the wall. Then she came over to comfort me, putting her arm around my shoulder.

It didn't take long to convince me that what had happened was the right thing. If we played our cards right, nothing would be too different. We could move to a different town where no one knew us and start over, we could get married as husband and wife. "We just need to make a few changes." Leslie said.

'A few changes' made me think something I had never thought before. I had a change of my own to make. Leslie followed me. I grabbed a pair of scissors off the bathroom counter and sat on the toilet with my legs spread, looking at the tiny little cock and balls that until yesterday had been a noble six and a half inches. I looked at Leslie and she nodded encouragement that I continue. Closing the scissors around my cock and balls, I cut them off easier than removing a skin tag. There was no pain and even less blood. I held some toilet paper to my smooth dickless crotch and lifted the lid on the toilet seat. I dropped the tiny cock and balls into the basin and flushed, watching my tiny dick and testicles go down the whirlpool and disappearing forever into the sewer drain.

"See how easy that was?" Leslie kissed me on the cheek. My mood brightened. I looked into her eyes.

"Ready for round two?" I asked and instantly she got hard. We both rushed back into the bedroom where she pounded my ass with her hard cock the rest of the day and the rest of our lives.
