Ria and Tracy trade partners for the massage

My cock stirred.

"What sort of treat?" Connor asked.

Ria was beaming. "How would you boys like it if Tracy and I traded places to give you your massages?"

We both agreed that we'd like it just fine.

Since we were all starting to get light-headed from the heat of the sauna, I suggested that we relocate to the living room, where Connor and I could stretch out on the twin sofas to enjoy full-body rubdowns from the girls.

"Full-body rubdowns, huh?" Tracy teased. "I wonder what's on HIS mind."

"What's to wonder?" I quipped.

Two minutes later, Connor and I were lying comfortably on our stomachs, waiting while the women ran upstairs to fetch some massage oil. I turned to my buddy and waived a disapproving finger at him. "Hey, how do you expect my wife to give you a proper back rub while you're wearing that stupid bathrobe?"

"You're sure?" he asked.

"Merry Christmas," I grinned, then I turned away as Connor started stripping down. While I had zero desire to see the guy naked, I knew Ria would be delighted with the view.

A moment later, the women came bouncing back down the stairs holding the two bottles of massage oil Ria and I had brought for the trip. They took one look at me and Connor—both of us lying nude on our respective sofas—and let out a pair of wolf-whistles for our benefit.

"Rowr! This is gonna be fun," Tracy cheered.

Tracy, still dressed in her infernally skimpy bathrobe, climbed up on top of me, her knees resting on either side of my hips. Warm, coconut-scented oil dripped down my body, all the way from my neck into the crack of my ass. I looked over at the other couch and watched as Ria straddled Connor's back, eagerly rubbing oil into his muscles.

"Shh, close your eyes, give them their privacy," Tracy whispered, gently turning my head to face the other direction. "And they'll give us ours."

I closed my eyes, luxuriated in the feel of Tracy's slender fingers caressing my bare skin, and forced myself to forget that Ria and Connor were even there.

There was nothing overtly erotic about Tracy's massage technique, but I was already so insanely aroused that her every touch felt like a red-hot ingot stroking across my oiled skin, kneading the tension from my exhausted muscles.

From my position lying face down on the sofa, I couldn't actually see what was happening, but I felt Tracy's weight shift, and an instant later I heard the whoosh of fabric as her bathrobe dropped to the floor at my side.

Meaning the big-breasted girl currently straddling me was totally naked.

As her massage moved lower down my body, Tracy scooted herself back, and I distinctly felt the hot, gushing wetness of her cunt lips as they brushed across my lower back, over the curve of my ass, and finally came to a stop resting on my leg.

Her hands moved lower as well—daringly—to gently squeeze the tops of my buttocks. I really wished she would just lose control and start groping me already, but, frustratingly, Tracy hesitated to go any further..

Then she removed her hands from my ass and just sat there, shifting her weight awkwardly on my legs.

What had happened? Was something wrong?

I heard the sound of Tracy squirting more massage oil from the bottle, and then a second later I felt her hands on me again—my shoulders, this time—supporting herself as she slowly lowered her chest...

Then she pressed the full weight of those massive, oiled tits onto my bare back.

I GROWLED, my toes curling and my fists reflexively holding onto the sofa cushions for dear life. Pleased with my reaction, Tracy got playful—sliding her slippery melons up and down across my naked body.

I wasn't the only one enjoying Tracy's massage. Her nipples were thick and hard as eraser nubs dragging across my oiled skin. Below, her pussy rubbed absent-mindedly against my leg, dripping with arousal.

She spun around a full 180 degrees, scooted her naked ass until she was straddling my upper back, and promptly dropped her oiled chest back down again—now using her hands to squeeze and grope at my bare buttocks.

I was so horny, I wanted to scream. As amazing as it felt having Tracy's big, juicy breasts slipping and sliding all over my naked back, I hated how there was nothing I could actually do while lying on my stomach. I wanted to see my masseuse; wanted to hold her and kiss her and fuck her until we both passed out from exhaustion.

Then I heard Connor moan—loudly—and my curiosity overwhelmed any compunction I had about spying on him with my wife.

I opened my eyes and spun my head around to see what was happening on the opposite couch.
