KATHY'S STORY by Kathy
* * * * *
My boyfriend likes my sister, Alexa. When I was away last year he took her out a couple of times, not as a date, but in order to be closer to me, virtually. Alexa is my twin.
Alexa was always quieter than I and never had the luck with guys--not all good luck, by any means--that I did. But she did like Robert and came along with us sometimes to the movies, or out on a picnic, or to a party when she was alone. I didn't mind; we were twins.
Last New Year's Rob and I threw a party at our house. It was very successful and a lot of our friends turned up. Alexa met a seemingly-nice guy named Jim and danced with him most of the evening. Just after midnight, however, I found her alone in the bathroom in a flood of tears.
"What's wrong?" I helped her off the floor and onto the commode seat. I wet a hand-towel and wiped her face. "Where is Jim?"
"We had an argument," she sobbed.
"Blow your nose," I told her.
She blew her nose into the hand towel and explained: "He wanted me to go home with him and I said no and he wanted to--hic--know why and I told him I liked him but I didn't think I should go home with him on the first--hic--date and we were all right for a while but after a while he started to--"
"Okay, okay," I said. "I get it."
She sniffed loudly. "I'm a moron, aren't I?"
I told her she was but I kissed her on the forehead to show her it was all right. "Where is he now?" I asked.
"Gone," she said morosely. "I think."
I left for a moment to circuit the house but Jim was indeed gone. Bastard.
"You stay here tonight," I told her. She was legally drunk anyway and I wasn't driving her home. I was a little drunk myself. And I wanted my sister.
"You're sure?" she said.
"Of course, I'm sure." I guided her back downstairs and into the kitchen and made her eat some food.
"Rob won't mind?"
A hilarious image ripped through my mind. "Rob wouldn't mind it if you fucked him," I said aloud.
She sprayed Doritos and dip into her hand. "Kathy!"
I started laughing.
"God!" She wiped her mouth and rinsed her hand under the faucet. "You shouldn't do that. You embarrass me."
"That's why I did it," I said.
At two o'clock we shut down the party and bedded our guests in every available space. Two couples and five singles shared the basement; Alexa was on the couch; four acquaintances lay on air mattresses in the living room, and four of my best friends were in the two spare bedrooms upstairs. I locked the bedroom door to keep the riffraff out.
"Are we gonna fuck?" Rob wanted to know.
"Are you gonna make me?" I asked him.
"I can make you if you want me too," he said.
I took off my clothes and made him screw me good.

At just after three o'clock I awoke and went to the bathroom. My bladder was bursting. We have two bathrooms upstairs so I had this one locked up. There was a knock on the corridor door.
"Kath?" It was Alexa.
"Yeah."
"Let me in."
I let her in and she scuttled over to the commode, yanked down her jeans and sat down. "Oh, God," she sighed, letting her urine out. "I thought I'd die."
I rinsed my hands and dried them on a towel. I played one hand through her blonde hair. "You okay?" I asked.
