Since you knew her, Luna has always been good at finding weird things on the web. Lately she's been mentioning a strange vaginal pump that for some scientific reason would cause breast enlargement.

You didn't think it was a real thing, until she warns you that not only she has already found and bought it... but that she has also already inserted it!

Now she just needs a piston to pull the valve on.

The girl begs you to help her to end her life as a flat girl as a surfboard. All you have to do is penetrate her and let the pump turn on, starting to enlarge her tits....

Now she just needs a piston to pull the valve on.

The girl begs you to help her to end her life as a flat girl as a surfboard. All you have to do is penetrate her and let the pump turn on, starting to enlarge her tits.

With a little reluctance, you give your consent. Luna is immediately over you, your penis inside her hot pussy. She starts to move clumsily on you, until finally you hear a sound of air being introduced into her: the valve is working! It's time to pump!

Luna starts to ride you and slowly her tits get bigger and bigger. after a while the girl has arrived at the desired size, but you don't want to stop... so you keep pumping, again and again. Luna is scared and begs you to stop, there's too much air inside her! Her tits are getting bigger and bigger, they're like two giant watermelons now. Her cries and implores still can't stop you, and you continue to pump her mercilessly with your piston-cock, until.. booom!
