I woke up from my nap sporting the usual erection. Our hosts, Bret and Denise, were nudists, as were Laura and me, and we all wandered around their townhome in various states of undress. I had fallen asleep on the couch completely naked, and now became aware of my hard-on as I stirred to consciousness. My hand wandered down to my shaft, and, eyes still closed, I explored my stiffness with my fingertips. I lightly stroked my balls, then gripped my cock and began masturbating with long, slow, easy strokes.
"You better save that for me!" I recognized Denise's voice, and opened my eyes. Laura and Denise were in the kitchen, which, along with the living room and dining area, was part a large great room. They were standing behind the counter, watching me and looking at each other and giggling. Denise was wearing an unbuttoned men's shirt and Laura was topless. I couldn't see any more than that behind the counter, but wearing panties was not the norm for either of them so I assumed they were both bottomless, too. "I want that cock tonight," Denise said to Laura. After watching Bret and me simultaneously pounding Laura's pussy last night, Denise had made Bret promise that she would get a double fucking tonight. "Oh, yeah? It's all yours, and I can't wait to watch," Laura told her, nuzzling her ear and pushing the open shirt aside to reveal the stiff nipple of Denise's left breast. It didn't take much to get those two going, and Denise apparently still had some pent up sexual energy from the night before because she responded immediately, turning to face Laura and kissing her deeply. I stroked my stiff member as I watched these beautiful women explore each other's mouths with their tongues. Denise briefly pinched Laura's nipple, then slid her hand down the naked skin of Laura's belly and out of my sight below the counter toward her crotch. Laura jumped and I knew that Denise had found her target. Laura pulled away slightly. "Oh, my pussy is so sore," she said.
"I'm not surprised after the way you got fucked last night!" Denise said in a playfully teasing tone. She put her arms around Laura's neck and looked at her seductively. She kissed her mouth, her tongue lightly playing across Laura's slightly parted lips. "Want me to kiss it and make it feel better?" she demurely asked.
"Oh, please do!" Laura replied. My cock twitched in my hand, and I began to stroke myself harder.
Denise led Laura by the hand around the counter toward me into the living room. They were completely wrapped up in each other, ignoring the fact that I was enthusiastically masturbating as I watched them. Now I could see that the shirt was all that Denise was wearing, and Laura was indeed completely naked. Denise seated Laura in the same armchair that she had sat in to masturbate while watching her husband and me fuck Laura the night before. She knelt in front of the chair and spread Laura legs wide. I sat up and moved down the couch a little to get a better view, my hard cock throbbing in my hand. Denise lightly kissed the inside of her thighs, working her way to Laura's wet slit. Her tongue lightly danced over the swollen vulva, and Laura's inner lips began to protrude as she got more and more turned on by Denise's oral ministrations. She probed Laura's pussy, working her tongue through the folds. Laura's erect clit peeked out from under its hood, and Denise played it with her lips and tongue, licking and sucking it like a little cock.
Denise was on her knees, bent over with her face in Laura's pussy. In this position, her shirt rode up so it only came about halfway down her ass. Her wet pussy was open to me, seductively framed by the material, her swollen inner lips clearly signaling her excitement. I got on my knees behind her and pushed the shirt up around her waist. I explored her wetness with one hand, and stroked my stiff rod with the other. Parting her lips, I ran the tip of my cock along her moist slit, and swirled it around her clit. Still sucking Laura, she wiggled her ass and pushed back against me. Sliding my manhood along her pussy lips, I found her entrance and eased my dick inside her. I fucked her slowly and deliberately while she ate out my girlfriend. Laura leaned back in the chair, making little contented purring sounds, pinching and playing with her erect nipples.
We continued our lazy lovemaking for a few minutes, and Laura looked down at me through half-closed eyes. It felt like I was fucking Laura right through Denise, my cock pushing Denise's face into Laura's pussy with each slow, deliberate thrust. We got a little lost in each other for a moment, using this beautiful girl between us, Laura grinding her pussy against her face, and me exploring her cunt with my stiffness.
