My twin sister fancied herself crazy and began creating avatars when she was sixteen. Her mother and her brother, me, went along with it because everything else about Elizabeth was so special. Some days it seemed as though all the good genes in our entire family tree had converged on her. She was, simultaneously, an athlete, a musician, a brilliant student, and many other things as well.
But growing up was still hard. If you perform well, regardless of what it is, others raise the bar. And then, when your hormones kick in, there are boys and sex and out of control emotions. More than once, I would come back from an evening with my buddies and hear her crying as I passed her door.
Her alternate personalities were her way of dealing with all the pressure. She wrote little short stories, not more than a paragraph or two, and posted them on the refrigerator and around the house, even on the back of the toilet. When she was prepping for something important, her latest creation always pulled off an outrageous trick of some kind.
The summer we were eighteen and headed to college in the fall, my girlfriend Jeannie and I were squeezed into a bunk at the family cottage, just waking up, when Beth walked in and sat on the edge of the bed. Jeannie was hiding under the sheet, not knowing who had come into the room.
"Justin, I have a meet today, but I'm eighteen now and there is a virginity problem Blanche and I need to talk about with you. And Jeannie too."
I was hardly awake, but managed to get out, "Ok. I guess. Tonight?"
"You don't need the details. I expect you to perform when the time comes." She poked a finger into Jeannie's thigh, which was long and sleek even with the sheet over her. "Franny, you are not to give him a hard time about this. It is ok to share." She leaned over for a quick kiss and disappeared.
Jeannie's fingers were squeezing my morning hardness, "I'm Franny now? That must have been crazy Blanche giving orders."
Before I could think of a reply, I was eased over on top of her and my cock guided into warm wetness. "Do me, we have to think about this."
Athletics seems to run in my family and friends, because everyone has a sport, and there are lots of ribbons and trophies scattered about. Jeannie was a long distance swimmer and hard as nails. She loved to thrust her bony hips into mine and groan. I had a terrible suspicion she was faking orgasms to keep me interested until one night we had a couple of forbidden beers and she spent an hour confessing that her old boyfriends never really turned her on and she didn't come for them, but faked it. She broke down in tears and cried on my chest. I tried to say it was ok, but she shouted, "No, it's not ok, damn it."
I was really scared I had screwed up until she blew her nose and whispered in my ear that the very first time I was in her, she came. "It's worse than that," she hissed, trying to pretend she was saying something awful, "I've come every time after that. You are a terrible, terrible beast and I love you." Which, of course, required another crying fit on my chest.
That morning, in the bunk bed, fucking each other, we made a little pact. We would stick together for the sake of Blanche's cherry. We would continue to fight for straight A's and go to the same selective college or university. To keep everyone offguard, including Elizabeth, we would have breakups. We would go to karate classes so we could practice taking each other out.
We were laughing and giggling and nothing was happening down below, when Jeannie said, "Get busy, you are still required to get me off every time."
We worked hard for those climaxes. Jeannie was about to let out a terrific scream when I clapped a hand over her mouth and jammed in as hard as I could.
Jeannie jerked and shook and opened her eyes very wide at someone behind me. Before I could turn around a terrific slap arrived on my butt. "You should be ashamed, abusing that poor woman. Does she always come for you like that?"
I rolled off Jeannie and said, "Mom, sex with Jeannie is the greatest. Get in here with us."
I knew my mother was needy. The smell under the covers was very strong, and we massaged all her best parts.
"Oh, you brats." She wiggled and squirmed in her silk nightie as we applied kisses and fingers. "Stop that this minute. Let me out of the bed."
Her hands were trying to beat on me and encountered a revived cock. "Jeannie, he is hard again. How do you control him?"
"It is a losing battle, Katherine. He is still growing and the coach has him in the weight room all the time."
"You mean this big hard cock is getting bigger too?"
"Yes, I lie around wanting and wanting him, and then afterwards, I am just wrecked."
The two of them had to have kissing after that, while my fingers explored. Mom was wet and two fingers went right in. The violent twisting and shaking increased as Jeannie's tongue kept busy and my thumb worked on a tender clit. Her wail was muffled by a pillow.
Jeannie and I giggled as Katherine caught her breath and mumbled about wayward kids. "What's this about you and your sister?"
Jeannie whispered in her ear, "She says he has to be her first. Is that bad or what?"
Mom had my slippery cock in a death grip. "You are not to take your sister's virginity. Understand?"
"I didn't start it! She jumped us with some story about Blanche had decided."
She let go and slumped against me. "What are we going to do, Justin? She has these wild stories that her avatars act out."
Jeannie sat on top of Katherine and kneaded her shoulders and back. "I think the two of you should relax. She is the smartest kid around. Maybe she will find a boyfriend of her own soon."
She giggled and added, "I could throw a jealousy fit and threaten to scratch her eyes out."
Mom and I got Jeannie between us and applied tickle torture. Quick as a wink, she gave mom a terrible hickey on her neck and laughed. "I'm getting you in trouble."
Katherine stood by the bed, flushed and wet. My mom followed my sexy girlfriend to the shower with her own threats.
Over breakfast, Katherine said, "You were right about Beth. We have to cool it."
The two of them had on long tee shirts and nothing else.
"Wandering around like that is not cooling me..."
"And Jeannie says that on the weekends, once is never enough..."
The look I got from my mother was enough to melt the icecap. Jeannie was at my side, her fingers pulling down my zipper, "She asked me if I would share."
Katherine raised her leg and straddled my thighs. The tee shirt disappeared over her head. We were still staring at each other. This had been building for a long time. My father's high blood pressure had wilted his cock, and finally killed him.
Mom's interest in sex had not diminished, and the knowledge that her son and his girlfriend were getting it on in my bedroom bothered the hell out of her. The look was telling me enough was enough. I was astonished that she had the presence of mind to ask Jeannie. A little light went on. This wasn't a one off. She was establishing new boundaries in the family.
I reached for her hips, easing them forward. Jeannie pulled her mouth off me, leaving the great slimy purple cock ready for the pussy advancing on it. I lifted and Jeannie pointed and in a quick move, we were joined.
