Enjoy the show*

"Oooh yes! Fuck me, Mr. Uribe! Pound my ass! Ohh, you pound my ass so good!"

Your eyes are glued to the action behind the two-way mirror where Bethany's husband Carlos has Ivy stripped naked and bent over a table while he rams his thick cock into her ass over and over again. Her perky tits press against the surface of the table and her own cock swings between her legs in time with Carlos' thrusts. Their balls slap together every time he buries himself deep inside her.

Next to you in the darkened both behind the glass sits Bethany. The lascivious grin on her face tells you she's actually enjoying watching her husband fuck this cute trans girl's brains out. Surprisingly, there isn't even a hint of jealousy in her expression.

"This room is supposed to be for observing test groups with new products," Bethany whispers. "But Carlos and I think this is more fun."

"Do they know you're watching?" you ask.

"Mmm hmm. At least, Carlos always assumes I'm watching. I don't know about her though. Legally, he's supposed to tell her, but sometimes he forgets." She stifles a giggle. "I can always tell afterwards by the look on the girl's face when he asks if I enjoyed the show."

Carlos flips Ivy on her back. Her wild and wavy red hair wreathes her flushed face and her perky nipples point to the ceiling. He grabs her by the thighs and sides his cock back into her ass. She leans her head back and moans with pleasure. You can see Ivy's erection growing as it slaps against her own stomach. Her moans only grow louder as he grabs her shaft and strokes it in time with his thrusts.

"Oh God, that's hot!" you hear Bethany say under her breath. Sneaking a peek in her direction, you see she has one hand under her skirt, no doubt pleasuring herself while she watches her husband absolutely dominate Ivy.

"Does he ever watch you have sex with other men in here too?" you ask, curious to know if the arrangement went both ways.

"Oh yes, many times. Well, not so much lately for obvious reasons, but we love watching each other have a good time. It's part of what makes our marriage special."

"Don't you ever get jealous?" you ask, still wrestling with your own feelings of anger and betrayal.

"Well, it's like this. I love Carlos just like you love Suzy, right?" she asks.

"Yes," you answer.

"And Carlos and I enjoy having sex just like you and Suzy do, right?"

"Yes."

And I love watching him do something he thoroughly enjoys, and I bet you feel the same way about Suzy, right?"

"... Yes" you say more hesitantly this time.

"So if he's having the time of his life fucking this cute girl's brains out, why wouldn't I want him to do that when I want to see him happy more than anything else in the world?"

"I... Wow! I never really thought of it that way." You feel completely dumbfounded. "Do you really think Suzy would..."

"Shh! Hold on, they're about to cum!" She shifts all her attention back to Carlos and Ivy. The fingers under her skirt pick up speed. You hear Ivy's moans and Carlos' grunts get louder. Ivy's cock starts to twitch. One spurt of cum shoots out over her body and lands in her hair. The next one plasters her chin. A third and fourth shot land on her tits. Each one after that travels shorter and shorter until the rest of her jizz dribbles out just below her stomach.

Next to you, Bethany is frantically rubbing herself with one hand and covering her mouth with the other, stifling the moans of her own climax. Her body tenses and she shudders one, twice, three times, and relaxes.

Back behind the glass, Carlos has finally pulled out of Ivy's now gaping butthole. She lays there on the table for a moment, catching her breath and letting his cum dribble out and pool underneath her until it drips off the edge of the table.
