Rob and I were sitting on the sofa and wondering what we could do with Carol next. I had put a few drops of Rob's drug in her drink at lunchtime and as soon as it had taken effect I put cushions on the coffee table and made her kneel on it with her legs apart and her ass in the air. I pulled her dress up to her waist and pulled her white panties half way down her thighs. We lay back stroking our hard cocks and enjoying Carol's erotic and humiliating position. Her smooth, shaven pussy pushed out below her firm, round ass cheeks. The pink pussy lips and her little brown puckered anus looked so inviting. I told her to put her hands behind her and pull her cheeks wide apart, exposing her delicious asshole even more.
"Holy shit, I could never get tired of looking at that ass," Rob said. He leaned forward and ran his tongue up and down her ass crack, tickling her anus and licking her pussy lips. He stood up and dropped his pants. "Mind if I fuck her Dave?" he asked. His big black cock was very hard and I could see a drop of precum on the glistening purple head as he pulled back his foreskin.
"I'm gonna empty my balls in your sweet cunt Carol. Let your hubby watch you getting fucked with a big nigga cock" he said as he held her pussy lips open.
"Stick it up her ass Rob," I told him. "I want to show you what she can do. Stand still and she'll make you come just moving her ass. I got her to do it to me the other day and it's fantastic. Try it, go on, let me see you do it."
Rob spat on Carol's asshole and rubbed saliva on his cock. I watched him press his cock against her anus and slowly push it until the head popped in. When the shaft was half way into her ass I told him to stop and hold it right there.
"Make him come Carol," I told her, "use your ass to bring him off."
Rob stood quite still and watched as Carol slowly moved her ass back and forth on his long black pole, squeezing it tightly with her sphincter, then relaxing the muscle before squeezing and relaxing it over and over again while slowly sliding her ass up and down his cock.
"Oh my God, this is incredible, feels like she's giving me a blow job with her ass," he gasped.
"I knew you'd like it," I said, "she's gonna give you one of the best orgasms you've ever had."
Carol continued to work on Rob's rock-hard dick, moving her hips to and fro, jacking him off with her tight asshole. I could see her sphincter contracting and relaxing as it went up and down his shaft. I jacked off as I watched. There's nothing I like more than seeing my wife with a big cock up her ass. I shot my wad in a Kleenex just as Rob gripped Carol's hips and ejaculated loads of hot cum deep into her bowels.
"That was amazing," he called out, "why the fuck haven't we done that before? It's so fucking good! He wiped up the sperm that was dripping out of her asshole and then she sat down on the sofa and went to sleep. I knew that she wouldn't remember a thing about what had happened when she woke up.
"What can we do with her Rob?" I asked, let's try and find something special, something we haven't done yet."
"I was talking about that with Mike last night," he replied. "He said why don't we take her dogging, we haven't tried that yet".
I had heard about dogging but I wasn't really sure what it meant. Rob explained that a couple would drive out to a certain place and have sex in the car while other people stood outside and watched the action. If the woman was really horny she might let some of the guys watching have a go with her. The popular place at the moment was a disused factory parking lot that wasn't too far away. I thought that sounded like a great idea. I could watch Carol exposing her beautiful naked body to a crowd of guys and see her giving herself to them. Just the kind of experience I crave for, letting other men use and abuse my lovely wife while I watch.
Rob said he would call Mike and get it fixed up. He would also get me another bottle of the drug as our supply was starting to run out.
Mike found out that there would be a dogging session at the car park on Friday, in three days time. We decided that Rob would drive Carol as it would look good seeing a blonde with a black guy, especially one with a cock the size of his! Mike and I would follow them to watch the action.
I reserved a table for Carol and me at a restaurant for Friday night. When the day came I told her I was really looking forward to making love to her that night and asked her to wear high heels, stockings and sexy underwear. I said that I would love to do it with her in the car like we used to.
