It's the Friday of a long weekend. Greetings and formalities aside, the three of you have enjoyed each other's company for an hour, catching up, having a drink and talking about the weekend ahead. As play begins, you are instructed to go to one of the many spare bedrooms in the sprawling beach house.
"I am so glad you're here." The wife says.
"This will be fun. Strip down, but leave your underwear on."
Now on display, you are instructed to get fully on the mattress, facing the foot of the bed, on your hands and knees. A blindfold is placed over your eyes.
You feel her close to you as she says "You are not to move or speak until we are ready for you. Do you understand?"
"Yes" you reply as the coolness of leather restraints are applied. One on each wrist. One on each thigh. And one on each ankle, pinned by the buckles in a perfect doggy-style position.
You wait excitedly. A hand runs across you. Another brushes the hair from your forehead. The sound of clothes being taken off is clear.
You hear, "Suck my cock." and instinctively open, but your mouth remains empty.
"Thats it" comes the growl of approval, but it isn't towards you.
Even with the blindfold on, you can tell they are close. Just a few inches in front of you, maybe. You want to reach out, to be a part of whatever is happening just beyond your darkness, but you were instructed not to move.
Some version of gagging, spit and "Oh fuck, right there" is your soundtrack for the next few minutes. Even without the visual you know she's doing a good job. Your mouth and pussy are both wet with excitement.
"Fuck me" you hear her hiss as she slides off of the cock. "I will, but first, her." comes the reply.
"Thank god", you think.
There is a bit of shuffling. A nightstand drawer opens. The mattress shifts slightly as you feel their bodies join you on the bed. A hand reaches up and slides your panties to the side.
You are shocked to feel not a cock, but the cool soft plastic of a vibrating dildo pressed against your opening. As a set of hands holds your cheeks open, another slowly works it into you, its vibrations and your excitement helping it along.
Not what you expected, but you're not turning it down. Once it is fully seated, its length inside of you and its vibrating "bunny ears" pressed against your clit, it shuts off.
And stays motionless inside you.
"Now" she says, matter of factly, "fuck me".
For the next several minutes you listen to the two work each other over in ways only partners who are familiar with each other can.
You hear moans and grunts.
Slaps and cries.
Explicit name calling and dirty talk clearly tested and approved over the years.
She comes at least once that you can tell, maybe twice.
But none of the action is directed at you.
As you stay positioned on all fours, your pussy still full with the motionless toy, the only "touch" you get is incidental. A foot hits your leg. When repositioning on the mattress someone brushes your back.
Occasionally the thrusts and bodies beyond your view will move with such force that it will slightly move the mattress, which just barely jostles the toy occupying you. But none of it is nearly enough.
A half hour in this position, between a blow job and the fucking, and all you've gotten is three minutes with a vibrator.
"I'm going to cum." you hear in a low voice. "Ok" she says.
