We'll never know what might have happened if Kevin had taken the three steps to reach me and my open mouth. I was so hot and turned on, I'm almost sure I would have sucked him into my mouth with scarcely any hesitation. I could see the lust in my brother's eyes and knew he was thinking about it. I didn't say a word -- just looked at his thick, stiff cock in his hand, dripping with fluid at the tip. I looked up at him and licked my lips. I waited -- letting him decide. I know now -- at least from my perspective -- if Kevin had wanted to use my mouth, I would have let him. Part of me was horrified, but another part of me wanted nothing more than to take my brother's cock in my mouth just like I was doing to his friend. As it was, though, Kevin shook his head and said, "Naw, dude, she's my sister." He started stroking himself again.
(And this is probably a good spot to satisfy and answer everybody's burning question -- NO! Kevin and I have never done anything sexual together. I think. -- but that's for another story. And I don't really care to hear any moralistic comments about what we did get up to - I know it's weird and incestuous, but we were horny and trying to figure some things out. And it also happens to be the truth and I promised myself if I was going to write this, it was going to be honest.)
"Suit yourself," said Benny. He pulled me back down on him and probably less than a minute later, my mouth was once again full of his seed. I'm pretty sure I moaned out of pure pleasure. If anything, it tasted even better than the night before. I kept sucking, getting every last drop out of his cock -- he was still hard as a rock and I would have gladly kept going until I got another one from him but he pushed me back on my heels and pulled his pants back up. I turned around just in time to see Kevin stuffing his cock back in his pants. I looked down where he had been standing and saw some white clumps of cum on the floor. He looked at me and nodded and smiled.
Benny brushed by, me still on my knees, and he and Kevin high-fived each other and then they just walked out, leaving me there with spit (and probably cum) running down my chin and a dazed expression on my face. I was so turned on and, now that they had left me there, frustrated. My pussy desperately needed some attention. I jammed my hand down the front of my shorts and started rubbing my clit and occasionally sticking a finger inside. I rocked back and forth on my knees, frantically masturbating myself until I came with a shudder and a low scream. Then I got up and went home.
So our routine became this: we walked home from school, and Benny and Kevin and I would go into the abandoned building and I would either blow Benny or fuck him (he fucked me for the first time about a week later) while Kevin watched and jacked off. We did this EVERY SINGLE DAY for about 6 months and then we finally tapered off a bit, but we still met probably twice a week. It was awesome.
Then I met Ray and things REALLY went off the rails.
