"We can talk about it tomorrow. I'm sorry but I'm going to bed."
He crawled in between the cool covers, and fell asleep almost immediately. He felt her as she came to bed and crawled very close to him a little later. But then he was asleep again. Robert awoke to the bed shaking thinking that what he felt was an earthquake.
He looked at Katie who had her back to him, and a hand between her legs rubbing herself violently. It didn't take very long until she was groaning, and then suddenly she was relaxed again.
When she fell asleep, he began to drift off. He awoke at one in the morning. She was doing it again. He placed his arms around her as she continued to masturbate wildly. When she finally came she turned around and hid her face in his shoulder and cried, hugging him hard.
"I'm sorry Robert," she sobbed, "Sometimes I just need it so bad, I can't stand it."
"It's OK Kitten, sometimes I need it too."
"Honest Robert? You need S-E-X?" she asked, spelling it out, "as much as I ... do?"
"Of course Kitten. There are times that I have to play with my penis, to relieve myself just like you were doing."
She got much closer, reached around him and pulled him as close as she could. When she pushed her belly against him, he was unable to control himself and began to get hard. He knew that there were rules against what they were thinking, so he moved back just a little, hoping she hadn't felt it, but it was too late,
"Robert was that your peepee poking me?"
"Yes ... I'm sorry."
"Don't be sorry. I like the feeling. It was nice."
"You had better go to sleep, my sexy little sister, before I ..."
"... before you what Robert?"
"Before I spank you bottom for being a naughty girl."
"I'm not naughty, I'm just interested. I have never been in bed with a man before. It's really nice. I like the feel of your body against me." "Go to sleep, we have almost eight hours of driving tomorrow."
"Why?"
"Well we want to get into Salt Lake to catch the train."
"But you said that the train departs at four in the morning. Wouldn't it be better to get there around midnight so we wouldn't have to wait so long?"
"I guess but I don't have our tickets yet and I have to turn in the car."
"You should call the car rental and ask where you can turn it in late, near the station, then call the station and make reservations for us on the train."
Robert was pleased that she knew a little bit about the outside world, and used her logic. He squeezed her hard and gave her a kiss on her forehead. She in turn grabbed hold of his face and pulled his lips down to her. She kissed him long and soft, finally sucking on his lower lip. Robert was a little excited and shoved his tongue into her sweet mouth, touching her tongue.
They continued this action for about a half hour, until he was on his back, and she was lying on top of him, her legs on both sides of him and her crotch rubbing on his swollen cock.
"Oh, your peepee feels so nice rubbing me down there Robert."
Robert remembered that she was his half sister, and shouldn't be doing this.
"Kitten maybe we should stop, before we go too far. Go to sleep and we can talk about it in the morning."
"Robert," she said, crawling off of him, "I'm so excited now. I have to relieve myself again."
As she lay on her left side, with him close behind her, she slid her hand into her panties and began to rub.
"If you want, I will help you Kitten."
"How", she asked looking at him over her shoulder. Robert reached under the covers took hold of her panties and pulled them down and off her feet. He then removed his jockey shorts and got close to her.
He lifted her right leg over his, and placed his hard penis between her legs pressing it to her crotch, her labia wetting his penis. Robert then moved his hip forward causing his sister to moan. He moved front to back for a while, then reached around with his left hand, taking hold of her full breast, playing with the nipple.
As she had been ready to cum when he began, she squirted and murmured, "Robert." He then pulled his penis free and she said,
"No don't take it away from me ... please."
Robert gently rolled her on her back and placed himself between her legs. Lowering his mouth to her bare pussy, he began to lick the tender mound. Katie made a light scream and said only,
"Oh R-o-b-e-r-t." As he sucked and licked she grabbed the sheets on both sides of her, her knuckles went white, her mouth open and her eyes shut tight. In the half hour Robert sucked and licked the pussy of the little ex-nun, she sprayed in his face three times. Finally he moved her legs up so her vagina was next to his mouth. He pushed his tongue inside of her, tongue fucking her, and she came again.
Robert lay down next to her and with her last small amount of energy she placed her arms around his neck, smiled at him and said,
"You are wonderful. That was the first time I have ever felt that good in my life. I love you little brother, and if you ever want to call me "baby" I won't mind. Robert kissed her lightly on her mouth, her nose, her cheeks, then moved down to her neck where he sucked a little too hard making a slight discoloration. She was becoming hot again and begged him for more.
He wasn't sure she was ready but decided he would take a chance, and slid her hand down to his very hard penis. She grabbed it as though she was drowning on the ocean, and his penis was a life preserver.
"OH Robert, thank you for everything you are so good to me and you know exactly what I need. This is the first peepee I have ever touched. The other postulates and I always talked about having a peepee to play with. Jenny told me that her boyfriend slid his into her many times and they made love, before her parents sent her to the nunnery. Is that what you want to do to me Robert?
"Yes Kitten it is, but not until you are ready."
"I think that I'm ready now Robert."
"But I don't have any condoms, and I don't want my sister to be pregnant with my baby."
"What are condoms Robert?"
"They are little rubber things that I put on my penis so my juice won't squirt into you and get you pregnant."
"They told us about pregnant at the convent, and said that if we wanted to be married to God, we would have to get a tubal."
Do you mean a tubal ligation."
"I think so, is that a bad thing?"
"When did that happen?"
"When I was thirteen and started my flowing blood."
"Those bastards sterilized you so you couldn't have babies. They tied your fallopian tubes so a man's sperm couldn't mix in with your egg?"
"Is that bad Robert?"
"Only if you want to have children."
"I have never wanted to have children, Robert. Are we going to make love now?
"Do you really want to?"
"Oh yes. Jenny told me that it was the most wonder feeling in the world, and I want to do it with you. Would you mind doing it with your sister?"
"No. If it's what you really want."
"I really want to Robert ... with you."
Robert wanted to treat her special, so he held her close for a long while, and kissed her tenderly. Moving down to her neck, he sucked long but not hard so as not to leave marks. She was responding to him with her whole body now.
He kept moving down kissing her just above her breasts, which were turning a bright pink; he then turned his attention to her nipples that stood up like little pencil erasers. He could feel that she was at the height of her excitement, due to the impulsive and uncontrolled movements of her body, so very slowly he knelt between her thighs.
She surprised him when her legs, hooked around his and attempted to pull him in. She was in fact very ready to take the next step, and who better to do it with, than her own brother, who loved her more than he ever knew he could.
He held his cock and gently slid the head up and down her slit touching her vaginal opening, then returning back to her clitoris, and back down again. Robert could feel he was making progress when he felt her short nails scraping his back. He was happy that the convent had made the nuns keep their nails short.
Knowing that his sister had never had a man before, he wanted her first time to be special, and slowly pushed his swollen cock into the slippery entrance of her vagina. She moaned and groaned, as the feeling to her was beyond anything she had ever experienced. She was no longer a child of God. With Robert's help she had become a child of lust. She loved the feeling he was giving her and would do anything to make him feel wonderful too.
Taking a long time Robert eased his penis into her pussy. It took almost forty minutes to push it in all of the way. He felt bad when her broke her cherry, because of the extreme pain it caused her, but she never complained holding him tight the whole time.
All she did to ease the pain was bite her lower lip. When his cock was finally in her all the way, she looked in his eyes and smiled, then nodded her head letting him know she was ready to do it with him.
As her pussy was so tight, Robert began very slowly which caused an almost intolerable feeling of a craving and desire for both of them.
"Please Robert." She said.
