My wife had always fantasized about it, but never did I think it would fulfill her as much as it did when it happened.
The two of us were alone in the house when I told her that I was going for a run. I'd already changed into my joggers and a sports vest, had my iPod strapped to my arm and was ready to go. Being stressed out for a few days, I needed to run off some energy, so it was going to be good to feel the burn. When I put my head around the corner of the bedroom, I wished I hadn't. My wife was trimming her pussy, her legs spread, and shaver in one hand while she spread her moist pussy-lips with the other. She looked up and flicked off the buzz of the trimmer.
"You heading out?" she asked, coyly. She cocked her head a little, more than a bit suggestively.
"Yeah, I want to stay fit. Tempted to stay here, though. If only you were taking it all off..." I teased. She looked back down at her mound and put the trimmer down, pulling her lips apart with both of her hands until I could see her glistening entrance. I noticed that her clitoris was already engorged.
"Maybe it will be in five minutes."
"I'll be half an hour, tops. Stay warm for me, and I'll be hot when I get back."
"If I can wait that long." She said, and massaged her clitoris with two fingertips, slowly, but firm enough to illicit a moan from her other lips.
"Don't be late..." she said, picking up the trimmer again.
"I want to find you flicking that clit when I get back." I said. My wife loves it when I'm commanding, and I knew that would get her wet.
I left the house with the faint buzz of the trimmer doing its work still in the air. After running up a sweat for around five minutes, I couldn't get the image of her lying on the bed fingering herself out of my head, and did a u-turn. I span back around and picked up a sprint to the house. When I got there, I thought I'd surprise my wife, so I jumped out of my jogging bottoms, tore off my t-shirt and silently closed the front door, climbing the stairs. I teased myself when got to the bedroom, and peered into the room inch by inch to treat myself. My wife's left hand was gripping the headboard, her face a picture of ecstasy. Clearly, she'd started without me. I moved forward slowly, noticing her erect nipples, shining proudly in the sunlight. Her back arched and I pushed my head closer to the open door, seeing her right arm pointing down to her pussy. It was moving rapidly, and I stepped forward to see her fingers at work. True enough, she had shaven her pussy entirely, and her black fingernails were flicking across her engorged clitoris, but looking lower down, I could see that they were also spreading her opening for the helmet of a large black cock. It was the most amazing thing I'd ever seen, her pale, white skin being so ferociously penetrated by a hard, black penis that was at least ten inches long. It was slipping in and out of her tight slit with growing speed. I looked up to her face again to see her biting her lip. Was she in pain?
I stepped back, pulling out of view, but still able to see what was happening in our marital bed. My wife, legs spread, was having the fucking of a lifetime by the biggest dick I'd ever seen. It opened her brutally with each stoke, and her face told the story. Her eyes were shut tight as she took it inside her while she masturbated. For a moment, I thought maybe she'd been discovered while naked on the bed and fucked blind, that she could think it was me inside her. I'm well hung and more than dominant in the bedroom, but those thoughts were rudely interrupted.
