When I got close to home I texted my sister, checking on the whereabouts of our parents. I wasn't to worry as they'd gone off to the casino and would stay overnight with friends. And why did I ask? I just replied I had a major surprise, knowing it would kill her having to wait.

But, she was in awe with my breasts, and then it got more intimate as I showed her my pussy. I told her everything about Bella and Charlene, and then about the new feelings inside me. 

My sister always surprises me. Instead of commenting either way, she got up and pulled me in a tight hug. And somehow it gave me strength to face my future, whatever it would be. And, as if she could read my mind, she whispered, “It will all be okay.”

What was interesting is that my breast size was very close to hers now, and we experimented with some of her clothes, where in the past I only tried stuff she was retiring. The conclusion was that I could wear anything she owned, and vice versa, proven by her wearing my new red dress. She looked amazing in it, and she made me promise that she could borrow it sometimes, after the prom of course. And suddenly we made a more serious promise together, that either one could borrow anything from the other. And I never felt so close to her as at that moment.

That night we had a pajama party together and I got to try out every nightie she had. We both chose the same one for me, a red silk slip that felt amazing on my skin. She commented that red was my color, and so were natural materials, and that it belonged to me now.

Not long after all my nails and my lips were painted a bright red, as she experimented with more severe makeup on my face. I loved how she managed to shadow my eyes in a way that it looked like my eyes were slanted a bit. And I guess that became my style as well.

It became more intimate when we talked about sex. Even though she believed me, that I was not interested in guys, she also explained that I should never say no, without trying. And suddenly she talked about her prom, and how she wanted her date to take her flower. But, the asshole ended up leaving with a different girl, and my sister ended up with a boy that felt sorry for her and took her home, after taking her virginity on the back seat. Not the romantic night she had hoped for, but she still remembered that feeling of the boy's meat filling her up. It went from painful at first to unbelievable pleasure real quick. 

And as she continued telling about a few boyfriends she had in college, the part of being filled by a dick kept arousing her. So much that she got herself a dildo, so she could get that feeling any time she wanted. And she showed a very realistic looking dick, much larger than mine had ever been.

I looked at her with renewed respect, my sweet sister being so hungry for dick. But she had opened that first beginning of curiosity in my mind on what it would feel like. And just like that my sister pulled my nightie up, and my panties down, and she added some “lube” on the dildo.

She didn't give me any time to protest or pull back, and as I laid down she slowly pushed that monster in my “never used before” pussy. Of course I couldn't even feel it pass my pussy lips, but the way my artificial vagina was routed, I could feel the pressure pushing against my own skin, as the intruder got deeper inside me. I think it was brushing my testicles as it suddenly felt like they were tickled, which I always do when I masturbate. And I concentrated on that nice feeling as I took in more.

Apparently my internal sleeve was long enough to take the six or maybe eight inches, but as Marsha started pumping it back and forth, it was no longer brushing, it was stimulating whatever of my manhood was hidden under there. And I could feel that familiar feeling building even though I knew there was no room for my dick to grow. And then I came!

Marsha was fascinated. She saw my cum squeeze from the little pee hole between my legs, and concluded that I had to be careful with any guy fucking me, even though my cum looked more like slime than semen. She scooped some up and licked her fingers clean, and she smacked her lips like she enjoyed it. She was also very horny herself now.

So, after my heartbeat came down finally, I had to use the same dildo on her, and make her cum also. “You're a girl now”, she said, “we do it all the time to each other.” I doubted that was true, but what did I know?

Fair is fair though, but I'd never seen a real pussy up close. I fingered her wetness first and without thinking sucked my finger clean, surprised by the sweet and salty taste. Then I started pushing the tip of the dildo between her lips, which almost seemed to suck it in. In seconds the monster was almost completely inside her, me just holding the end. I pulled it back and started pumping her, and she moaned her approval. 

She was clearly worked up, because when I touched a finger on what I assumed was her swollen clit, she came hard. Cum squeezed past the dildo and soaked my hand as I heard her muffled scream. I quickly pulled the dildo from her, hoping to stop the flood, but her cum hit me right in the face now, and with my little experience I did the only thing I could think of to stop her from wetting the bed, and I covered her cunt with my mouth.

I was partly proud of making her cum so hard, and partly confused as I never thought of girls ejeculating cum, but my mouth filled up real quickly with the fluid I had tasted already, and I had to swallow it away. What I didn't realize was that me sucking her pussy now caused her orgasm to continue, and I had no idea why I stuck my tongue into the mix. All I know is that her insides were on fire, everywhere the tip of my tongue touched her, and another gulf of cum followed to cool it down. And I drank.

I think I had overloaded her, as she started to push my face away from her crotch. It had finally stopped gushing and I think I accomplished my task of keeping the sheets dry. Then finally I heard her say, “Oh Rhonda… if I had known you were this good, I would have given myself to you years ago. That was the best fucking fuck I ever had!”

I had no clue how to reply, because I had no clue what exactly I had done to make her say something like that. But I smiled anyway, licking my lips clean from the last bit of her nectar. I guess my sister and I made each other cum, and as wrong as that sounded, I hoped we could do it again already.

But my sister was exhausted and she patted the bed for me to lay next to her, so I curled up beside her and pulled the blanket over us. Her arm came immediately across me, resting on my breast, and I suddenly felt good. Good and tired, and when I closed my eyes, everything went dark.

So, not only did I have dildo sex with my sister, we also slept in the same bed, and the only thing that caused us not to feel weird was the fact that I was another girl, rather than her brother. I decided that sleeping on my side as well as on my back felt good with my breasts, but when I tried turning on my belly for a second I quickly gave up on that. I also found that my own hands kept running across my silk nightie, and I realized it gave me the same thrill as the leather.

When Marsha finally woke up we discussed the situation, but she was very simple about it. She wanted Rhonda in her bed any time possible and fuck with her like rabbits. I was still surprised that I had cum from being penetrated, but she told me not to worry, because I was meant to please a woman. I was worried about being gay, and she basically told me I was a lesbian. Not very helpful…

The nice thing she had planned was a day of shopping to “expand our wardrobe”. She had a pretty good idea what was missing, specifically for me. But first, as she made breakfast, did I take a shower, as a girl. I loved soaping my breasts, even though I couldn't feel it. And I fingered my pussy, trying to get some of that lube out, but then I wondered if I should leave it in, and always be lubed up? But the damage was done, I could feel my finger in me touch just the right spot, and from there I tried frantically to make myself cum. And it was the image of Veronica, not my sister, poking me with a dildo, that took me over the edge.

Marsha had put an outfit for me on the bed, and it was as girly as it could be, but I figured I was all in now. I liked the skirt and I knew exactly which of her shoes to wear with it. Only much later did I realize that a day of shopping in three inch heels is a feat that not many women pull off, but I guess it's all part of the learning curve.

So yes, sex had opened a whole new bond between me and my sister, and so did shopping. I don't recall ever shopping and having so much fun. The fact that anything we bought could be worn by either of us, added both hilarity and healthy frustration. I had a lot to learn, but I did bring a few new ideas to the table. One of them was a leather skirt, the other a pair of thigh high boots. She insisted on a corset and also a waist cincher for me, and she had me wear the latter during the day. I loved shopping for lingerie, but I couldn't tell if it was my male mind convincing me to buy the thongs and the body stocking.

So, a perfect day, that ended in a disastrous night. As we got back home, still laughing about the enormous amount of bags we were carrying, there was our mom waiting for us. And if I had any notion of acting like I was one of Marsha's friends, when my mother said “Hi Rhonda”, I knew I was in trouble.

But I wasn't, I think. I guess my dad didn't know yet. He had dropped off mom as he needed to buy some tool or something, and she had collected the laundry from my room. And my fake license was right there on my desk. Her first reaction was anger indeed, and she'd wanted to call me right away about it. But then she'd gone through my drawers and found my girl clothes, and she knew something bigger was going on.

And now she looked at me, like I was under a microscope, and eventually she just said “wow”. She saw me in the girl I was, but the two of us looked like very happy sisters, and as a mother she approved of that. So we sat down together, and I confessed my years of cross dressing up to my plan of going to the prom. Thank God for Marsha on chipping in at just the right moments, as I saw mom slowly accept the new me.

The new me… I had to chuckle, because even I had no idea who exactly the new me was. But I surely loved being a girl, I had found out in the last few days. But, I knew I had to get back in boy mode, as I had a few more tests at school to go through. So when mom said that dad would be back soon, and we should go upstairs, so she could work on him first, I suggested I'd change back into Ron, as school was waiting the next day. From the look on mom's face I could tell she was happy with the extra time we gave her.

Marsha helped me to remove my breasts and my makeup. And my nail polish. But I said no on my pussy. I was going to keep it, even while being Ron. And I could see that she understood.

It was funny that mom was a little bit disappointed about losing her new daughter again, but we had no time to discuss it, as my father arrived home. He was oblivious of the awkward atmosphere in the house, and he started right away at the job in the garage, for which he had needed his new tool.

Mom came with us to Marsha's room, and we showed her my prom dress. She actually took quite an interest in the dress, and the shoes and the accessories I wanted to wear. She insisted I would get my ears pierced and that I would wear a special set of earrings from her. It was clear that she embraced her second daughter even while I looked like her son again.

It took a week before mom finally told my dad, as I finished all my final exams. On Friday I was off, and I wouldn't go back to school for five days. Then three more days until prom. My mom insisted I was Rhonda for all but the one day in school.

It's one thing when your sister helps you when you transform into a girl. But when your mom gets involved there were many details that we hadn't thought of. And she wanted me to be perfect for when dad came home. Perfect meant a complete removal of all my body hair. It meant a professional makeover on my face, with just enough being held back so that I could become Ron again if needed. It meant an insanely expensive new wig, but boy, did I love it. It was raven black and would go perfect with my red dress, and the red and black makeup session she had planned for me before prom.

When dad came home I wore my new black leather skirt, as mom knew he'd like that. She had informed him that morning, just before he left for work, about me wanting to be a girl sometimes, and she'd told me he took it well enough. Which meant he didn't barge into my room to pound some sanity into me.

So, when he came in, and saw my sister and me together, he started smiling and took me in a hug. Not what any of us had expected, but apparently his biggest worry was that I would look like a guy in drag. But I looked exactly like another daughter and he didn't mind. He wanted to know how permanent it was, and I told him I didn't know yet. Then he wanted to know if I was gay, and I said I didn't think so, I still liked girls. He warned me not to become some slut, something I had heard him tell my sister a few times, and I promised that would be easy.

So yeah, when prom came, I'd been a full-time girl for eight out of nine days, my mother overseeing my diet, my makeup, my salon visit, nail extensions, and a number of things that only daughters learn, including how to handle boys. My sister stood by me the whole time, and we managed two sexual encounters together. 

I had to go through a series of photo sessions, in my red dress, with the beautiful drops hanging from my ears, the matching golden necklace, bracelets and even an anklet. By myself, with mom, with Marsha, with both of them, even with my father, who had the proudest look on his face. I had vague memories of my sister going through all of this two years ago. I shared a few of my pictures with Charlene, who cheered me on.

As I had no date, my sister dropped me off at school, and she'd pick me up the moment I would text her. I looked perfect in my leather she told me, and that was exactly the confidence booster I needed.

I got quite some looks, as expected, as nine out of ten girls were wearing long prom dresses. I thought they all looked beautiful and I was a bit disappointed that I hadn't found such a dress with my budget. But most boys looked at me with lust in their eyes, even if they were with a girl.

I never had to get myself one drink. And I spent quite some time on the dance floor. And I liked the fact that I was desired. But when one boy tried to kiss me during a slow number, I made it clear to him I wasn't interested in that. That's when I saw Veronica. 

She was on the dance floor herself, with one of the guys I had danced with already. I thought she looked beautiful, and like me she was not wearing a standard prom dress. I think her dress would be called an evening gown, made from what looked like gold metal. And I felt a thrill go through my body, as first I wondered what it would feel like with my hands on her hips, then what that dress would look like on me.

I'm not sure if she saw me brush off my dance partner, but shortly after I left the floor to find my drink at the little table for two, I saw her find her group of friends, and I recognized some of them. The smart girls I thought, or the nerds, as my own nerd friends called them. I noticed that Veronica never sat down, instead she took her glass, said a few words to the other girls, and then walked straight into my direction. 

“Is this seat available?” she asked, pointing at the other chair at my table. I said “Sure, be my guest.”

As she sat down she said, “I don't remember seeing you around?”

It was somewhere between a statement and a question, so I answered, “I've been around. I remember you. You're Veronica right?”

A pleasant surprise flushed her face, and she nodded. “Then you must be….?”

“Rhonda” was all I said, but I really wanted to tell her all about me.

Now, in our school with about five hundred seniors it's not uncommon to only know a small group, the people you take classes with, or have been taking with in years before. So I gave her a small hint. “I'm in your Advanced Math class. I know you're brilliant at it.” I hoped I wasn't overdoing it.

I could almost see the gears in her brain work. She looked intensely at me, then I could see the light go on. “You're Ronald. Ron. Rhonda!” I nodded, then I said softly, “Please, I don't need everyone to know.”

She nodded as well and I saw fascination rather than anger in her face. “I noticed you didn't want that boy to kiss you on the floor. You dress as a girl, a beautiful girl, but you're not interested in boys?” I shook my head, but pleased with her calling me beautiful. 

“Of course. You tried to hook up with me once. I'm sorry that I wasn't interested, but I'm not into boys either.”

So she did remember. And she was into girls. And I was a girl now, and… “Does that mean you may be interested in me now?”

She laughed, sweet, and then said, “You may now be exactly what I need.”

So, I wasn't the only confused one here. Veronica, with all her smarts, with no interest in boys, had not been able to really hook up with girls either, and she had been clearly confused in her sexual orientation. And suddenly, thanks to me, she got a handle on it. She was very open about the fact that she was attracted to me, which got me to reply that she was the only one I ever had set my eyes on.
