He almost wished there had been something that pointed to oneor other of them being the killer. As it was he had another fivepotential suspects to inv...estigate and get close to, which meant that overthe next few weeks he would be spending a lot of time on his back withhis legs in the air, faking orgasms and telling each of them what a totalstud they were. He wished there was another way of flushing out thekiller, but having considered all the other options he was sure this wasthe only one likely. I was working on him when he reached down and started to stroke my hair. I was busted. I crawled up for a kiss and that started the fun and fireworks. We lost an hour or more of sleep but we were well satisfied when we went back to sleep and I thought it was worth it.When the alarm went off, it was time to get up. Rob sent me to take a rinse off shower while he went to get the coffee going and pull out some things for breakfast. I dressed in cargo shorts and a polo shirt, there wasn't the need. .. ?Le... Le... Leave m... m... m... me alone, or I'll... ?She managed to stammer out. But I rudely interrupted her and snarled ?What are you going to do! Tell Miss Jones... Yesterday when I was truant...?? She just stood there, close to tears, pleading us to leave her alone. In vain of course, as I really wanted to hurt her, to hear her scream from pain. So with an evil grin, I began to unzip her, all to long and matronly, skirt. Desperate she cling to it, but a hard slap in the face,. I had only taken about 5 strokes when she came, I kept fucking her like a whore, a few minuets later she came again, I kept going, her pussy was so wet it felt like my dick was swimming. When I finally came it was in gallons, I shot cum into her pussy 6 times, are combined fluids were leaking out of her pussy around my dick as I collapsed on top of her.After a few minuets I regained my strength and crawled off my sister and moved up beside her, I undid her hand restraints, she hugged me tight.
