Help from my sister

At the time I was 25 and my sister was 29. My name is Gil and her is Judy.
Judy had been having relationship problems with her boyfriend who she had moved in with, for some time and asked to crash at my house for a few days. I was in the only bathroom where I was getting ready for a Friday night date.

"Gil, you almost done, I gotta go to the bathroom real badly," Judy said.

"I'll be out soon. I just wanna be ready for my date," I replied.

But Judy had to go to the bathroom very badly. She was spoiled a bit in the other house which had 3 bathrooms. So she never had to wait for someone. She was quickly getting more and more impatient. After about another minute she could not wait anymore. She just came in as I was completely naked and somewhat hard.

"Judy, I'm naked in here. Can't you wait just a few more minutes," I asked.

"No, I can't wait anymore. I really gotta go to the bathroom. And besides we've seen each other naked a million times, I've gone to the bathroom while you were in the shower many times before," Judy replied.

Then she undid her pants and pulled them down along with her underwear and sat down to go number 1. It was true, we had seen each other naked many times before. But we've haven't done that in years though. She went to the bathroom for a minute while I was man skaping myself and she couldn't help but notice my somewhat big erection.

"Gil, your hard, are you turned on right now," Judy asked.

"Yes, a little. But it's because I'm gonna get laid tonight," I replied.

"When was the last time you had sex? I mean your hoping to score with that," Judy asked.

"Well, I have before," I replied.

Then Judy finished up and pulled up her underwear and pants and flushed as I still stood there completely naked. She didn't leave right away though. She looked down at my hard dick for a few more seconds.

"Gil, you should make your dick bigger before you try to have sex with any girl. I think you'll have much better chances with a bigger dick," Judy said.

"Well big sister, just for the sake of argument, how do you propose I do that, besides have sex," I asked.

Then she got down on her knees right in front of me as I was still naked and she grabbed ahold of my dick firmly.

"Well by letting me do this," Judy replied.

She took my dick in her mouth for a few minutes. I was stunned by what was
happening. I had a small incest crush on her for a few years, but never said anything for fear of what she might think or do. In a of couple minutes, I couldn't take it anymore and I had to cum.

"Judy I'm gonna cum," I said.

Then she took her mouth off my dick and I came a great deal in the toilet. Then she backed up a few inches and looked at my dick to see if it was bigger at all. It was just a little. Then she stood up.

"You certainly can cum big brother, any woman will be lucky to have sex with you." Judy said.

Then Judy got very close to me as I was still naked and looked down at my dick.

"Well I think my dick is actually bigger now, thank big sister. I love you." I said.

"Your welcome little brother, I love you too," Judy whispered in my ear just before she left.
