Peggy and Paul were as close as siblings could be. They were only one year apart in age, and he always included her in outings with his group of friends and she did the same. They were so comfortable with each other that people mistakenly thought they were a couple.
When Peggy turned eighteen his feelings for her began to change. The once gangly teenager had turned into a beautiful young woman. Tall and very thin with blonde hair and blue eyes, and cute small breasts and a tiny heart shaped ass. He wished he had a girlfriend who looked like his sister and had a funny kind personality like her.
Paul had relationships with women, but they were always short term and unsatisfying. No one could live up to his standards, that a woman had to be like his beloved Peggy.
Her dating history was also not great. Even though she had so much going for her and everything many men would desire, she dated loser after loser, who only cared about her looks and were very controlling.
When she turned thirty a loser got her pregnant and disappeared shortly after. Peggy did not believe in abortion and although she had a job, it would be a struggle financially to raise the child as a single mother.
Meanwhile Paul had become a financial wizard and made enough money in stocks to retire if he wanted to. He called her one day when she was three months pregnant to see how she was doing.
"I don't want you to worry about me Paul, but I don't know how I am going to financially afford my baby. With mom and dad gone and my inheritance spent I have no one to help me financially. I'll try to make it through somehow."
"Peggy that's no problem, why don't you move in with me. I have plenty of room in my house for you and the baby and it gets lonely here. I miss my 'little sister' being around. We were so close, but I feel like we have drifted apart over the years with you focused on your relationships."
"I'm sorry Paul, I should have spent more time with you instead of pinning my hopes for a family with men who couldn't even take care of themselves, no less being an equal partner. But won't your girlfriend be upset if I move in with you?"
"I broke up with her last week."
"Why?
"Because I didn't feel the closeness like I do with you. My ex and I never shared our hopes and dreams, and inside jokes, like we always did."
"I didn't realize you felt that way about me. It sounds like I was a hard act to follow! I'm glad I gave you a positive experience with me growing up. I feel the same way about you."
"Yeah Peggy but you made it hard for other women to equal what I had with you. I want you to quit your job and move in with me. I have plenty of money and can take of you both as long as you need me to."
"I can't believe you are doing this for me. You are the best big brother a girl could ever have!"
Paul helped Peggy move her few possessions from her tiny studio apartment. She had been to his large home before but didn't remember how big it really was. He moved her into a large bedroom next to his, and her room had an adjoining room that she could make into a nursery for the baby.
They settled in and got into a routine as if they were husband and wife. During the day he worked on his investments while Peggy cooked, cleaned, and did his laundry. He could hire someone to do these chores, but he preferred not to have anyone live in his house.
At night they would watch TV. On weekends or when Paul needed a break they would go out hiking, to concerts or take day trips and would laugh and reminisce about old times.
Paul found himself getting increasingly attracted to his sister but felt guilty about his incestuous feelings. But he also was jealous of other guys, and the baby growing in her belly reminded him of that.
When they would watch TV or go to a movie they would snuggle together and sometimes he even put his arm around her in a comforting way, although it was a little weird. Sometimes he would hear her sobbing softly about not having a father for her baby.
Peggy would often walk around in just a long tee shirt and panties, and Paul wondered whether she was teasing him. She was just starting to show a small baby bump. They both worked out a lot in Paul's home gym and watching his sister bend over in her yoga pants would almost put him over the edge of sanity.
One night they were watching TV in their sweatpants and Paul couldn't take it anymore and had to say something. "Peggy, I wish you were my girlfriend and that your baby was mine."
Peggy looked at him like someone had slapped her in the face. "I know you feel close to me as a sister, but that is a crazy thing to say. That would be incest and that would be very wrong." But his words had started to make her pussy involuntarily tingle, which disgusted her.
"Would it be very wrong, or do you really feel the same urges?"
He reached over and gently held the back of her head and leaned in and kissed her tenderly on the lips, but she quickly broke off the kiss.
"Paul, what are you doing! I am your sister not your girlfriend."
"But you are going to be my girlfriend. I can't let another man have you anymore."
He moved in for another kiss, but she pushed him off her with her arms.
"Paul, stop we can't do this!"
"I'll stop if you let me put my hand down your pants and check to see if you are wet."
"You will do no such thing. If I am wet it is because it is just a reaction, like when a woman cums when she is being raped."
"So you want me to rape you, so you don't feel guilty about having your brother's cock inside of that beautiful pussy of yours?"
"How do you know what it looks like?"
"You didn't notice but I accidentally walked in on you and saw you changing. You are even more beautiful with your little baby bump. Pregnant women really turn me on, especially when they start lactating."
"You are sick in the head, this is ridiculous. Let me up, I am going to bed!"
"You are going to bed with me tonight. This has been going on for a long time. Since you turned eighteen you have been teasing me for years. Enough is enough."
"I might have flirted with you, but it was just a joke."
"But this is no joke." With that he pulled down his sweatpants, exposing his long, thick, and hard penis.
"Put that thing away Paul. If you stop I will try to forget that you tried to rape your sister, you sick bastard."
He quickly pulled up her tee shirt before she could react and grabbed her wrists. He realized she wasn't wearing a bra. He bent in and started sucking on the now painfully erect nipples of her pert shapely breasts.
She immediately got wetter but wanted him to stop, even though she started moaning softly.
"Please stop. This is wrong. I am not doing this. The only way I am having sex with you is if you rape me!"
