Brotherly Love, Sisterly Love

"What are you doing man?" I said, turning, shocked, to face him.

"I thought you'd want to feel what it would be like for it to be someone else getting you off for a change."

"Yeah," I said, as if stating the obvious, "A girl, not you."

"Don't worry," he said, "I know just the thing, wait right here." He grabbed the sky blue panties that lay across my crotch, "I'm gonna need these."

With that, he left the room and I sat there on the bed waiting, with my pants around my ankles and my cock exposed. I wondered what he was up to. We were normally so knowledgeable about each other's secrets but I had no idea what was happening now. I had to admit that when he had put his hand on my cock, my body had sung with a little thrill of excitement, but it was just too strange, he was a man, and my brother, after all. Now, after waiting for quite a while, I was no longer aroused or curious but becoming a little bored. I had just bent over to pull my pants back up when I heard footsteps and an unfamiliar voice in the doorway.

"You wanted a girl, well, how about me?"

I looked up, startled, I didn't think there was anybody in the house, and there was Robert standing in the doorway. Or rather, not quite the usual Robert. At first glance, it was indeed a pretty teenage girl, albeit a short haired, flat chested one. Only after a second was it apparent that it was my twin brother dressed up. He was wearing some of Charlotte's sexy clothes, his legs were bare except for a tiny, short denim mini-skirt of hers and three inch wedge sandals on his feet. Fortunately, his legs like mine were largely hairless and it was now pretty clear that Charlotte wasn't the only one to have inherited our mother's long, elegant, feminine legs. On top of that, the girl, or rather Robert, was wearing a pale blue satin camisole that we had seen in Charlotte's catalogue paired with the panties I had had earlier. Sure enough, Robert lifted his skirt to give me a little flash of underneath to show me he was now wearing the same panties. The cami was made of satin thin enough to show Robert's skin beneath and was decorated with white and turquoise green flowers, much like the panties. I could see that he was also wearing shimmering pink lipgloss.
