Last year's science

Tammy's grin grows wider as she looks at Matilda:

"Hey sis, remember my science project from last year?"

Matilda giggles as clearly she does remember.

"Yeahhhh, it's still set up in the garage isn't it?"

"Come on Sam" says Tammy "Out to the garage"

As you follow the girls out to the garage, you try to remember Tammy's science project from last year. When you step into the garage it hits you like a ton of bricks!

"Here it is" says Tammy "The Milk-O-Tron Mark 1"

Tammy's science project was a machine that could attempt to extract the milk from any animal. And now you were that animal.

"Tammy, please..."

"Now Sam, it's all for science." Tammy assures you. "Just need you on all fours in the proper position please."

You duly oblige. A circle in each corner marks where your limbs should go, while a much smaller in the circle indicates where your penis will go. Your head is bowed down so you can't see Tammy pressing the remote control that tightens the circles, clamping you in position.

"Hey what the..."

"Relax Sam, it's so you wont move and ruin the experiment. Matilda, get the hood!"

"Hood? What do you mean hood?" You ask

"To put over your head so no-one recognizes you. We need to take a video of our experiment." As Tammy is explaining, the machine is tilting you back off all fours and into an upright position, leaving your tiny embarrassment jutting out.

Matilda returns and gets up close as she pops the hood over your head. She deliberately fumbles as she brushes against your cock. Blinded, you can now feel a hand around your cock as it clamps it into the middle circle of the milking machine.

"Lights, camera, ACTION!!!!!" Tammy says with a laugh
