A skimpy see-through nightie

"You like it?" she asked innocently.

Tracy had slipped into a pale blue nightie; a dainty, bell-shaped whiff of sheer mesh that draped like a veil over her ample curves and down past her hips-not quite covering the matching nylon panties she was wearing.

The mesh material was so utterly transparent that I could see every exquisite detail of her unsupported breasts as they bounced and swayed upon her return to the bed. A pair of teeny tiny ribbons-loosely knotted above her shoulders-were all that kept the whole ensemble from sliding down to a puddle at her feet.

"My god..." I sighed, drinking in the erotic vision before me.

Smiling, Tracy threw herself onto the mattress, the impact jiggling her bosom quite nicely.

I couldn't control my eyes, which ran a marathon around her generous curves. "You look sexier right now than you've ever looked, in any of the countless thousands of fantasies I've had of you over the years."

"Even better than I looked in the shower yesterday, with my big, soapy tits wrapped around your cock?"

I growled into another kiss. "Even better," I insisted.

"Even better than this morning when you were grinding your cock all over my ass?"

"Better."

"Even better than-"

"Better."

She seemed satisfied with my answer, and rewarded me by deliberately placing my hands atop her enormous bosom. I couldn't stop staring at that nightie:

"You brought this with you?" I asked, suspicious.

"Yeah..."

"But you didn't even know Connor was coming up this week."

Tracy blushed a deep crimson, and whispered, "I bought it for you."

"For me?"

She shrugged, self-conscious. "I didn't think anything was actually going to happen, I just wanted to see that look on your face again when I wore it."

"What look?"

"THIS look, silly," she laughed, pointing up at me. "The same look you gave me last Christmas when I popped out of that box and started dancing for you. The look that makes me feel like the sexiest woman in the whole wide world."

I crawled on top of her, enjoying the way her nearly naked body instinctively responded to the feel of my silk pajamas against her skin. Tracy arched her back, thrusting those full breasts up into my chest. I craned my neck down and licked her engorged nipples through the pale mesh fabric.

"You bastard," she grinned, cupping my butt with both her hands. "You know what silk does to me."

Her soft thighs embraced me on either side, rubbing up and down from my hips to my knees-slowly grinding my erect penis against her panties.

In the other room, we could hear my wife and Tracy's boyfriend both scream their way though a couple spine-shattering orgasms.

Tracy blushed. I placed a firm hand on her bare thigh and whispered, "We can top that."

"I'm counting on it," she grinned.

Our lips molded back together, tongues teasing. Hands roaming. Hips grinding.

Then she pulled my face away and whispered, "I have a confession to make."

"Oh yeah?"

"Yeah. All these cross-ups between the four of us-all this swinging or swapping or whatever you want to call it-it was my idea."

"Don't be silly, we all wanted it."

"We all wanted it, but I'm the one who-Mmm!-made it happen!"

She gave a jolt as my hand cupped the outside of her warm, wet panties.

"Last year, I-Ooh yes!-got so obsessed with the idea of fucking you that I-Unh!-I hatched this whole plan to get Connor together with Ria. I figured if the two of them had sex, then you and I could-Oh yes!"

I stroked a single finger across the outline of her pussy lips.

Tracy continued, "I got the idea when Ria was out shopping for her bridal lingerie. I took one glance at how fucking hot she looked, and I knew that Connor wouldn't be able to control himself if he saw her like that."

"So you-?"

"I filled Ria's head with a bunch nonsense about her needing to get a 'man's perspective.' Which meant putting on a show for Connor. I wanted to get them both so hot for each other that they crossed a line. Did something so naughty, they couldn't ignore what had happened. Then you and I would have an excuse to do the same. I even told Connor to start touching her..."

My heart was pounding. I pulled aside Tracy's drenched panties and wiggled a finger inside her boiling hot cunt.

"You told Connor to touch my wife?" I asked.

"Yes! Oh yes! I knew it was wrong, but I just couldn't help myself. I had to do something. We were all so fucking horny for each other, I knew it would only take a tiny push to get the ball rolling. And it almost worked! A week later, Ria asked me to strip for you. When Ria told me I could've touched you I almost screamed. I thought about going back to your room, ripping off your pants, and stuffing your cock in my mouth."

"Jesus," I panted. My grip on her waist tightened.

"When Connor asked me what to do before going to see Ria, I just told him to go as far as he could. I was hoping he would blur the lines or at least do something that Ria would want too much to do again. I didn't realize it would work so well."

I shook my head in amusement, "You did all that, just so you'd have an excuse to fool around with me?"

She nodded, clearly nervous about how I'd respond.
