Caution: This story contains strong elements of incest sex between catholic brother and his older sister resulting in her getting pregnant

Man did I ever love jerking off. It's something I did really well. I first started doing it in my room when I was alone in the house. A magazine, a bottle of baby oil, and my own imagination is all I needed, and my hand of course. Eventually, I realized it was more exciting to masturbate when my sister's friends were over. I would listen to them talking, hearing every word easily through the thin wall that seperated our two rooms. It is here that I first found out that my sister, Mary, was still a virgin.

For some reason knowing this I began to jerk off when only my sister was in there. I would create many fantasies involving the two of us, always ending the same way, with me taking her for the first time.

Soon though to continue on with my daydreaming I needed more, so I stole a pair of her panties out of her dresser. Thin, cotton, white with a lace trim I jacked myself into them. I would later wash and return them, no one the wiser.

But even that didn't work for long, so whenever Mary took a shower I would sneek into her room and swipe the pair that she had just taken off. Placing it over my nose I would breathe in the beautiful aroma of my sister, knowing nobody else had ever done so. And then of course I blew my load into them. After her shower when she couldn't find them I simply told her Mom was doing a wash, nothing more was ever said.

Doing it in her room only made it more exciting. Laying first on the bed and then actually under the covers knowing that this is where my sister slept I had the best orgasm of my life up to that point. Our parents were deeply religious, life was sacred to them in all its glories, but masturbation was considered a grave sin. If they had seen what I was doing in Mary's bed I'm sure they would have condemned me forever, yelling sinner, repent, repent, or some bullshit like that.

Once, well, more than once, I even went into her room when she was sleeping. Right up to her bed I went with my dick in hand. I must have blown quarts of my sperm into the tissues I brought with me.

One morning we were in the living room drinking coffee when she set hers down on the table and went to the bathroom so I, yes, you guessed it, I jerked off into it. Watching Mary drink it I went hard again.

"Coffee's good this morning, is it a new kind?"

"I put cream in it for you when I made it."

"Yum, I like the cream." Hearing that with my chair facing slightly away from her and my hand now wrapped around my cock I blew another load right into my shorts. Feeding it to her would now be something I did on a regular basis, at least once a day for the next three years. By the time Mary was seventeen her body had fully developed. A perfect figure, huge firm breasts, and the most beautiful creamy white skin. I couldn't help but wonder if the old saying was true-you are what you eat.

I didn't know a woman could jerk off until I found a pair of her panties early one morning in her laundry basket. They were soaked, and not from pee, the smell was different, almost sweet. Occasionally, I couldn't find the bottle of handcream that I used and now I knew why, she was using it too. I would watch her take it into her room and close the door. With my ear against her door I would hear her moaning very softly.

The idea that Mary and I were using the same bottle of handcream gave me an immediate hardon. As soon as she came out of her room and returned the bottle to its place I would grab it and go to my room. The same cream I was putting on me Mary was putting on her. I rolled that around in my head for a minute, and then I jacked off right into the open bottle itself. The next time she did it my cum would actually be on her. She would rub it over and around her clit or so I guessed not really knowing how women did it.

As I began to do this more and more, the bottle's contents weren't going down as fast now, a much greater amount of my sperm would be on my sister, it would be just like I had ejaculated all over her.

And then one day about a month after I had started doing this I awoke to hear Mary crying so I went to see what was wrong.

"I'm pregnant."

"How do you know sis."

"I've been tired lately and a girlfriend, just kidding of course, said maybe I was pregnant. I laughed but she said she had one of her sister's test kits, why not have some fun and see how it works. It came back positive, but this is impossible."

"How do you mean?" Of course I already knew but I didn't want her knowing that I knew.

"I haven't been with a guy before."

"Oh, I see."

"Yeah well, I sucked off a guy once, but you can't get pregnant from swallowing it, can you?"

I told her I was pretty sure you couldn't. Meanwhile the image of my sister sucking off some guy plus the knowledge that she was probably carrying my baby made me hard again.

"Mom and Dad are going to kill me." Out of nowhere Mary hugged me tight and started crying on my shoulder. "I feel so alone, please just hold me."

Now I was beginning to feel bad for Mary, and angry at what I had done. I hugged her back and then told her what I had done.

Mary's first punch hit me square on the jaw knocking me onto the floor. She was on me in a heartbeat with a left hook that almost took my head off.

"You fucking pervert, you son of a bitch, look what you've done, you, you, asshole." And with that she gave me an uppercut that loosened several of my teeth. Straddling me at the waist she would hit me twice more and stopped.

"You little bastard, you're hard right now, I can feel you under me, you God damn sick little pervert."

Mary got up off me and paced around the room.

"Well if I'm going to Hell for this so are you."

"Do we have to tell?"

"I'm not having an abortion if that's what you mean, I've always been against that."

I thought about my next words carefully.

"Mary, I know you hate me, but if you want, I'll help raise our baby."

Sis stared at me for some time, almost right through me at first but I could see her soften.

"Do you mean that?"

"Yes, I do." I got up off the floor and sat beside her on the bed. "When Mom gets home, I'll tell her what I did, none of this was your fault."

Mary was on the verge of tears.

"But they'll send you away."

"Probably, I might have to live with our Uncle or something."

Mary started to cry now so I hugged her. She didn't pull away like I thought she would, in fact she returned the embrace drawing me in closer. She felt so weak in my arms, surprising considering the bruises now forming on my face. I gently laid her down on the bed, my intentions were to get back up again but she wouldn't let go, she even kissed me on the cheek.

"I'm so sorry Mary, I really am. We'll get through this, I promise."

"Make love to me."

"What?" I must have heard wrong.

"Make love to me, please."

"Mary, what are you talking about?"

"I can't give birth to a baby while I'm a virgin. If someone from the Church finds out and talks, you know there are a lot of fanatics out there and crazy religious groups, they'll think I'm the mother of our saviour, the second coming of Christ."

Thinking about it I could see the tabloids now, 'Virgin Sister Mary Gives Birth to Boy, names him Jesus.'

"Please, I can't live like that, I'll do anything, I'll suck your dick, I'll let you fuck me whenever you want, I swallow, I'll take it all, just please, please."



"You had me at hello."

"Excuse me?"

"Oh, sorry, movie I saw the other day. You had me at I'll suck your dick."

And so we made love and I took her virginity, therefore you could almost say I prevented the second coming of Christ by cumming myself, inside my sister that is.

When I went to tell Mom and Dad what I had done Mary stopped me. She couldn't bare the idea of being alone. She would tell them it was a boy at a party. I thanked her later in her room.

"I love you Mary."

"And I love you, stay with me tonight."

"I didn't think you would want me in here."

"But I love you, and I mean it. I would often touch myself in here and whenever I did I would imagine it was you touching me."

I crawled into bed beside my sister and we slept in each other's arms, from then on I always wanted to be near her. As her body grew beside me so did our love for one another, my beautiful sister Mary, no longer a virgin, and me.
