A man

She is sporting short black hair, her build seems a bit more masculine, and she is wearing a long-sleeved shirt and jeans.

“I pulled my hair into a bun, put a cap over it, and a wig over that.” She then pulls down one of her sleeves a bit, and I can see a body suit. She also lifts her shirt up and I can see a fake six-pack.

“Okay, we are starting to run a little late, so put on your heels and let’s go,” she says.

She puts on some boots, while I take the heels I grabbed from the box and put them on. It takes a moment for me to get used to walking on them as we head out the door. My wife heads to the driver's side and I stumble a few times and am glad when I sit down in the passenger seat.

As we drive over my wife says, “In case it wasn’t clear, you’re my bimbo girlfriend, and I’m your strong sexy boyfriend. I said before that your butt plug was a part of your costume. Well, I’m wearing a strap-on dildo under my pants. It’s the same size as your plug”

I look and there is very clearly a kind of bulge in her pants. Both the butt plug and her dildo are a couple inches larger than my own dick which is kind of embarrassing.
