It's the most wonderful time of the year... when my family has it's annual gathering to put aside all the disfunction and celebrate the holidays. This year was special, as my little sister April had recently announced she was pregnant... this was to be the first grandchild in our family.

I arrived at my parents house -- the house I grew up in -- and dropped my bags in my old bedroom. My parents had left our rooms pretty much as they had been when we lived there, which was a bit strange now that I was 40 years old.

April was already there, settling in to her room. We had neve rbeen very close, as she was 14 years younger than me. My parents insisted she was planned, but we weren't sure about that. Anyway, I was off to college before she was even five, so I only saw her at holidays and summers until I eventually moved out on my own.

Although she was my sister, I have to admit I always found her sexy. I can remember coming home for holidays in the past and seeing her developing from a little girl into a woman. On more than one occasion I has snuck into her room and taken panties from her hamper, using them to stroke my cock until I blew a thick load of cum in the crotch.

April met her husband right after college and was married soon after. He was a jerk and no one in the family liked him. As a protective older brother, I disliked him more than anyone else and, although I was happy to hear my sister was pregnant, I had mixed
feelings.

I went to April's room to say hi and was surprised to see she was alone. She explained that Dan (her husband) had too much work to join her for the trip, and I acted disappointed. She saw right through me and called me on it.

I know she was only two months pregnant, but you certainly couldn't tell when looking at her. She looked amazing and I found myself getting hard as I sat talking to her. When she excused herself for a minute to go to the bathroom, I grabbed for a pair of her panties from her suitcase. When she returned, I told her I had to unpack and would see her after. I then went to the bathroom and unloaded a huge wad of cream on her panties. I stuffed the panties in the cabinet under the sink, knowing I would probably need to jack off several more times during this visit.

Our family gathering was like most of the rest, with lots of eating and drinking, some arguements, etc. Two days into the trip and I was counting the days until I was out of there. The only thing that kept me going was the daily (or more like 3-4 times daily) jackoff session into April's panties. By day four, the panties were harding from the crusted cum loads I had deposited on it.

On the last night of my visit, I excused myself after dinner to go stroke again. When I got to the bathroom and opened the cabinet, the panties were gone. Panic set in and I didn't know what to think. I had to find those panties. I opened the bathroom door and was greeted by April, her cum crusted panties in hand.

"Looking for these?" she said.

I couldn't speak, and became flushed with embarrassment.

"Relax," she said. "I won't tell anyone. Follow me."

Without thinking, I followed her to her room, not sure what to expect.

"So, up to your old tricks, huh?" she said. "I knew you did this when I was in my teens, but I didn't know you still did it."

I still couldn't speak, so she did the talking.

"Why beat off and fantasize about it, when you can have it?" she said. "You do want it, don't you?"

I still couldn't speak.

"This is perfect," she said. "I'm pregnant, so you don't have to worry about knocking me up. Do you want to fuck your little sister?"

I think I nodded, but wasn't sure. She just laughed and dropped to her knees in front of me. She opened my pants and pulled my already hard cock out. She licked and sucked on it, and I instinctively grabbed her head and face fucked her. I felt my balls tightening and moaned slightly as the cum erupted from my cock and down her throat. She kept sucking until I was done cumming, and kept me from going soft.

"Wasn't that better than shooting it on my panties," she laughed. "Now it's my turn."

She stripped out of her clothes and lie on the bed. Her pussy was shaved bald and looked so good. I dove in and ate her out until she came against my face. Then I climbed on top of her and pushed my cock inside her.

"Fuck your little sister," she moaned. "Fill me with your cream."

I fucked April hard and fast until I felt my orgasm approaching.

"Cum inside me big brother."

The words were hardly out of her mouth when the hot load of cum filled her cunt. I rolled off of her as my cock went soft. April got up and began to dress.

"I sure hope this worked," she said.

Confused, I finally managed to get a few words out.

"What worked?" I asked.

"I'm at the peak of my cycle. I'm hoping your seed gives me a baby."

I lay there more confused than ever.

"You don't get it, do you?" she said. "Dan is sterile. But I knew I couldn't get you to fuck me unless you thought it was safe."

"What?"

"That's right big brother. I'm hoping you knocked me up. Besides, you can't tell me you didn't want to fuck me, can you?"

I couldn't deny it. I had fantasized about it for years and was both thirlled and relieved when the opportunity finally presented itself. but I never thought about fathering her child.

"Relax," she said. "Dan will never know. No one needs to know. This will be our little secret."

With that, she left the room. I didn't hear from my sister again for three months, when she called to tell me she was really pregnant this time. I assume it was mine, although i guess I will never really know. All i can say is that she told me she hopes to have a large family.. maybe four kids... and she looks forward to seeing me at the next holiday gathering.
