Yes, later that day

Hoping against hope that Alison would return, I took a shower and headed out to the local sex shop to pick up a silver bullet and a dildo. As I walked the aisles looking for my purchases, I replayed our encounter over and over in my head. I was hard and had to stop to think about plumbing and lawn fertilizer once I had both items in hand, so that I could approach the checkout counter without embarrassment. Unfortunately, the cashier was blond like Alison and similar in age and appearance. My woody came back with a vengeance. I managed to pay and leave without her noticing. I rushed home with my prizes.

Then I proceeded to clean the house, especially the family room and the bedroom. I could then go to work and get something done, though my productivity was affected by constant imaginings of Alison, her sex toys, and my cock.

When I arrived home, I became suspicious after I walked in from the garage, because I could hear the television in the family room. I knew I had turned it off before leaving for the sex store.

I walked very quietly to the door to the room. One of my porn disks was playing, showing four women masturbating for the one man in the room. He was slowly stroking himself for the assembled women. I could see a pair of trim legs sticking out from the easy chair in front of the television, and I heard soft moaning coming from the occupant.

"Oh, Mr. Carter. Come for me. Give me your sweet spunk." I recognized Alison's voice.

I unzipped my jeans and pulled out my thickening cock. I crept into the room. The door was behind the chair, so it was pretty easy to not be noticed. I reached the point where I could look down into the chair without being seen. Alison was completely naked and had my wife's dildo pistoning into her pussy; her other hand was rubbing her clit like a mad fiend. The sight got me instantly hard, and I began stroking my cock. I was right next to the chair, and I planned on turning at the last second to spurt over her body.

One by one, the women on the DVD began climaxing. I was really close, and I could tell from this morning's activities that Alison would go soon, too. After the second woman came and just as the third was getting ready to, Alison let out a loud groan and her body stiffened.

"Oh, that's it, Mr. Carter. Yes! Yes!"

I took one step forward and turned, my cock spurting cum in long arcs on her belly and tits. Alison gasped, her eyes snapping open to look at my erupting cock. It took her a moment to register, and then she sat up and grabbed me, swallowing my cock in her delicious teen mouth. I moaned loud enough to make the dog bark. The dildo was still embedded perversely in her cunt as she sucked my juices down. She bobbed and licked my shaft until I finished and collapsed to lean on the chair back. My wilting cock slipped from her lips, and I panted to catch my breath.
