Robbie gave a cry and his body stiffened and the girl's eyes shot open. I tried to imagine what she was feeling as Robbie's sperm poured into her mouth but I couldn't.
I very quickly got the impression that the girl was not feeling as thrilled as I thought she might be. She jumped up from the grass and I could tell she was pissed. She grabbed her shirt and strode back around the edge of the pool heading for the gate and screaming at Robbie. I stepped back from the window as she passed so she wouldn't see me and then moved back to look at Robbie.
The poor guy was still kneeling on the grass with his cock sticking out and a trickle of sperm running from his knob onto the ground. He looked over his shoulder as the gate crashed shut and slammed the ground with his fists.
I guess the girl didn't like the idea of having a mouth full of sperm but if she didn't want it then she shouldn't have sucked Robbie's cock.
I quickly forgot my own feelings when I saw how sad Robbie looked. He looked so dejected, kneeling out there that I wanted to go to him and give him a hug but that would let him know that I had been watching and then he'd get pissed at me. I stared at his cock. It was beginning to shrink a little but it still looked pretty big to me. He sure had a nice one. One I wished I could see close up.
Did I really want that? Did I really want to see my brother's cock all hard and stiff? My pussy twitched and judging by the way my heart was pounding, I guess I did. It seemed like a terrible thing to think but it had been that kind of day, what with Dave rubbing his cock against my back and then seeing my brother getting his cock sucked right in front of me even if he didn't know I was there.
CHAPTER TWO
I decided that Robbie needed some affection from his little sister to compensate him for the girl not wanting to take all his sperm and then walking out on him. He must feel like a piece of shit. I put on my most see-through nightie and quickly made my way to the living room before he came back into the house. I hadn't given a whole lot of. thought as to what form that affection would take but I figured that somehow it would sort itself out. Whatever it was, it was going to be from a person who cared about him and would have no preset barriers for him. That much I did know.
I turned the TV on and set the volume real quiet then stretched out on the couch like I was dozing. I heard the front door close and my heart started thumping again. I mean, there I was, lying on the couch in a nightie that barely covered my pussy and not a stitch on underneath and my brother about to walk in on me and see me virtually naked.
His footsteps turned down the hallway towards his bedroom and my heart sank about ten miles. Surely he wasn't going straight to bed? How could he do that to me when I wanted to comfort him and show him sisterly concern? How inconsiderate of him!
Then it dawned on me where he was headed, the bathroom of course. He had to clean himself up after his little episode outside. I slid off the couch and walked as silently as I could towards the lighted doorway.
He was all the way in the back, standing at the toilet, and I suddenly knew exactly what I was going to do.
It was like a revelation, a flash of light in my brain.
I crept up behind him and slipped my arms around his waist. "Hi there!" I said cheerily and he jumped, sending a jet of pee all over the bathroom floor.
"Anna!" he shouted. "What the fuck do you think you're doing? Get out of here! I'm taking a pee."
I wrapped my arms tighter around his slim waist and rubbed my pussy against his ass. Robbie does have a nice butt, incidentally. "I want to stay and see you finish your pee," I said.
"You're crazy or drunk," he said.
"I'm neither but I still want to watch."
He had stopped peeing and I stood up on tiptoes to peer over his shoulder. His cock was still quite thick and he held it tightly in his right hand. "What's wrong? Are you finished already?"
"No, I haven't but I can't go with you here," he said.
"Sure you can," I replied brightly. "You just need a little help." I reached down and placed my hand over his.
"I don't believe you're doing this, Anna," he said but I could tell he wasn't angry with me or anything.
"I just want to help you. Let me hold it and just relax." I took his hand away and his cock hung down limply, pointing at the toilet bowl. This was the moment I had waited for; a full grown, albeit limp cock to get my hands on.
I took hold of it as gently as I could. It looked so lovely that I didn't want to handle it roughly and hurt it.
"Come on, brother," I said. "Relax and go pee for Anna. That's a good boy."
A small stream of pee flowed from his cock and I aimed it carefully into the water in the bowl. It was fun and I found myself wishing I had a cock too so I could aim into the water instead of having to squat.
The stream finally stopped and I shook the drops off the end. I don't know whether it was my imagination or maybe just wishful thinking but it seemed to me that his cock was getting a little larger as I held it. I hoped it was, because I wanted to see it at its best and maybe even touch it. Just touching his limp one was exciting enough and my pussy was starting to get wet all over again. I stood there with my brother's cock in my hand and neither of us made any move to put it away.
"Anna," – he said quietly. "Why are you behaving this way?"
"Just curious about the male anatomy," I said lightly.
"Bullshit. You've had plenty of opportunities to check me out before and never done it. What gives tonight?"
I sighed and gave his cock a little friendly squeeze. It was time to confess. I took a deep breath and tightened my grip on his cock. It was definitely getting bigger. It was NOT my imagination. "I saw you and the girl outside tonight."
Robbie's body sagged a little and I pressed harder against his lovely butt. "Oh shit," he moaned. "And just what did you see, little sister?"
"Everything. From the moment you got down on the grass to the time when the girl got up and left you."
"Oh no."
"Yes," I said softly. "I was lying on my bed when I heard the gate slam and I went to the window to see who was there. I know I shouldn't have stayed and watched you and the girl but it was fascinating and exciting to see what you were doing."
"So why are you doing this?"
That was a good question and deserved an answer. So I told him. "I wanted to show you that you were loved after that girl had gotten so pissed at you for coming in her mouth. Why did she suck you like that if she didn't want you to come?"
"Some girls like to suck, dear Anna, but they don't like come in their mouths. I didn't know she was one of that type. Now I do," he added sadly.
That made sense. I could see that sucking a cock was one thing but having it spit come inside your mouth might be something else altogether. I still had his cock in my hand and on an impulse I slid his foreskin back over the knob. Even though it swelled up a little more I could sense that Robbie was feeling uncomfortable about the whole thing. I mean, it's not every day that your sister walks in on you and grabs your cock while you're peeing. I decided to ease the situation by putting his cock back into his pants for him but there was evil brewing in my brain. I hadn't finished with my dear brother yet. Not by a long way.
I zipped him up and he turned to face me. His eyes met mine and he smiled his sweet smile. Then his eyes moved slowly down over my body. My nipples were sticking out hard and dark under my transparent nightie and I saw him staring at them. I wondered if his cock was getting any harder. I sure hoped it was.
His strong hands gripped my shoulders and he kissed me on the cheek then very softly on the lips. "I think I'll go to bed now," he said quietly.
"Can I keep you company for a while?" I asked. "It's too hot to sleep and I want to talk to you. I've got so many questions running around in my head and that's why God invented big brothers. To answer little sister's dumb questions."
