Grind (Cal and Macy's Story 2)

"Green means there's room available inside if we want to go in," Macy whispers to me. "Red means it's at capacity."

I nod, figuring she also knows this from the welcome brochure she received via email.

We pass a room where a woman is tied to a St. Andrew's cross with a man kneeling before her, eating her out. A lone couple stands by the window watching while the woman has her partner's pants open, lazily stroking his cock while he sips on his drink.

Everyone's just so... casual about it. I expect they're long-time customers.

Another room we pass has two men inside having sex. Definitely not my cup of tea, so although Macy slows her progress and cranes her neck to look, I give her a little push forward.

The next room has a man and a woman standing by the window watching and a green light above the door. Macy stops and steps up to the window, peering in.

The sight that greets me is erotic.

There's a single king-sized bed in the center of the room. All the lights are off except for a single, bright light just above, casting a golden halo on the naked couple in the center of the mattress. It makes for a dramatic effect, and my dick starts to swell as we watch the man fucking the woman from behind.

They're a fantastic-looking couple. She's blonde and lithe with huge tits that sway back and forth as he bangs her. He's well muscled, tattooed, and his face is covered by a henchman's mask, creating an air of menace about him as he pounds into her.

I'm stunned when one of the women standing next to Macy at the window reaches a hand forward and pushes a button on the window ledge. She leans forward and in a soft voice says, "Spank her ass while you fuck her."

I jerk in surprise, and Macy snaps her head toward the woman briefly before turning her face back to the window. Apparently, it's a speaker system where the watchers can request the couple perform certain acts.

The man in the henchman's mask pulls one arm back and lets it fly, his hand coming down against her flesh with a resounding crack that we can hear through the window. She gives out an equally resounding wail of pleasure mixed with pain and grinds back on his cock.

A small gasp of interest whispers out of Macy's mouth, and she steps closer to the glass to watch. My blood starts racing as I watch her watching the fucking couple, and my erection starts to rapidly get harder.

"Let's go check something else out," the man says to the woman standing next to us, and then they're gone.

Macy practically has her nose pressed to the glass, and I can see from the movement along her shoulder blades that her breathing has turned shallow. I step up behind her, very close, and press my stiff cock against her. My hands go to her hips, and I hold her in place while I bend so my lips graze against her ear. "Turning you on?"

She nods and grinds back into me. Taking one of my hands, she drags it across her stomach and then pushes it lower... down between her legs.

I don't need any further encouragement and I quickly grab the hem of her short dress, pushing my fingers up underneath. Just as I expect, I find her without underwear and my fingers are gently brushing in between her slick lips. She's drenched, and now my cock is throbbing to get inside of her.

Someone bumps my shoulder and I turn to see another couple standing beside us, peering into the window. The man glances over at me, lowering his eyes downward to where my hand is slowly moving between Macy's legs. His lips curve up slightly, and he turns back to the window to watch.

I know Macy likes others to watch, so I decide to keep going. I push a finger roughly inside of her. She gasps and her head falls back onto my shoulder.

"Feel good?" I whisper.

She gives a moan and swivels her hips, trying to draw me in deeper. "Let's go inside."

I close my eyes, drawing on my inner strength to let me be the man that she needs tonight. "Let's do it."

After a small kiss to her temple, I remove my hand from under her dress and smooth it down. Macy laces her fingers with mine again and leads me through the door.

Once we're inside and my eyes adjust, I immediately see a huge guy standing in the corner of the room on the other side of the window. He's dressed in black jeans and a black t-shirt, and he walks over to us, flipping a button on the wall.

"This room is only for two couples who want to swing," he says in a low voice. "We're now at capacity. Only rules are to be respectful of everyone and wear a condom if you switch partners. I'll be over here so if anyone feels like they need my intervention, just ask."

That does not make me feel safer for some reason, because I can't imagine a scenario that could escalate with just two couples and a bodyguard standing watch. But I don't say anything, because I see Macy gliding toward the bed to get a closer look.

I look over my shoulder briefly and see a few more people standing at the window watching us, and it leads to a moment of extreme shyness. So extreme, I almost tell Macy I'm leaving, but then she turns that beautiful face toward me and asks, "Are you okay with this?"

I walk over to her, trying to ignore the sounds of slapping flesh as the man continues to fuck the woman from behind while intermittently spanking her ass. Reaching up, I place my palm against her cheek, the bottom of her mask bumping against it. "What do you want to do in here?"

In an uncharacteristic display of uncertainty, Macy lowers her eyes to the floor and shrugs. "I don't know. Just... something. This room only has the four of us, so I figure it would be less intimidating for you."

I take in a deep breath and let it out, my eyes flicking back over to the window where masked faces press in on us.

"What don't you want to do?" Macy asks, giving me the power to set boundaries.

I answer without hesitation. Cutting my eyes to the man in the henchman's mask, I say, "I don't want him to fuck you."

I expect her to be offended, but she rewards me instead with the sweetest, most-adoring smile. "Of course not," she assures me.

"And I'm not fucking her," I add on, because while that was a given for me, I need to make sure she understands that as well.

She nods with a mischievous grin. "Got it. No actual swinging."

"But I guess anything else goes," I say hesitantly, because as long as I don't dip my wick somewhere else, and as long as no strange cock is in her pussy, I'm feeling definitely more at ease with this situation. In fact, the thought of us now fucking in front of strangers is starting to excite the hell out of me.

And yeah... maybe a little girl-on-girl action wouldn't bother me either. My cock thumps inside my pants, wholeheartedly agreeing.

"Then let's get naked, baby," Macy says and kicks off her heels. In one swift move, she whips her dress over her head and my mouth goes dry at the sight of her beautiful body just barely illuminated from the light over the middle of the bed.

Never missing a single thrust, the man on the bed mutters, "Damn baby... you are fucking fine."

I glare at him, but then my attention is caught by Macy's hands working at my clothes. "Let's get that cock out," she murmurs. "I want to suck on it a bit."

I give a longing groan at the thought and let her strip me bare. The couple on the bed are watching her remove my clothes without a single pause in their fucking. I can tell the woman's getting close by her loud whimpers and the guy is tunneling hard and fast into her with a clenched jaw.

Macy gives me a hard push and starts me walking backward. Within three strides, something catches me on the back of the knees, and I realize there was a low couch just to the other side of the bed. I sit down on it hard, Macy quickly gets my shoes, socks and pants off, and then I'm bare-ass naked with my cock pointing straight up.

"I want you so much," she whispers as she falls to her knees before me.

Chapter 15

My world starts spinning when she sucks my cock into her warm mouth.

The couple on the bed, five feet from us, are fucking at a furious pace. A small turn of my head and I see the masked strangers standing at the window watching us like hawks. I feel like I'm smack in the middle of a porn video, and fuck all my sensibilities, it's the dirtiest, hottest thing I've ever done in my life.

And yet... I'm not sure this is right. I have misgivings that are taking up a lot of room in my head, but they apparently aren't communicating with my dick, which is hard as a rock.

"Fuck... I'm coming," the man on the bed shouts, and my head jerks his way. His muscles tense all over as he slams into the woman with a long grunt, causing her to scream out. Her body shudders hard as she starts her own orgasm.

It's so fucking erotic with Macy's head bobbing between my legs and the strangers watching us beyond the glass, and I get filled with such primal lust that I have the sudden urge to fuck anything within arm's reach.

I watch in a daze as the woman crawls off the bed while the man rolls to the side, placing his feet on the floor as he tries to catch his breath. His face, hidden by black silk, raises and watches Macy blowing me.
