The black one

Suddenly the device locks down tightly around your dick. You panic, as it's really squeezing now.
The harder you try to pull out, the more you feel locked, almost like a chinese fingertrap.

Then you realize the cord is retracting and doing the same for Anna's. It's slowly pulling you into the hub. You try to resist, but it has a firm hold on you, so you have **** but to inch forward as it slides you closer.

Closer now. Your dick is less than a foot away from the device, the cord still retracting in. Anna is looking pleadingly and lustfully at your eyes.

It slides you both closer together. She leans in and plants her lips on yours, willing her tongue into you.
You still feel the device pulling you ever closer.

Her breasts press up against your chest.

Then it happens. The device pulls you all the way into the hub, the plastic phallus inside of anna had slid aside and made way for your dick. The machine willed you forward. You could feel the tip of your dick press against the Anna's slit. Then "plup" it slid into her in a pop.

Anna let's out a little gasp "Ohhhh.."

The machine gives one final push and breaks apart around you as intended. You're now completely inside of her. She moans. She gasps. Her minxy eyes lustfully gaze into yours and she bites her lip.

You reach around, take hold of her ass and go to work.
