Hey everyone, this is the 5th part of "muscle from outer space" ^^! 

The aliens are gladly surprised the humans subjects react so well, they are the first one to make so much growth with this new steroid formula they just created. But they are getting way to big to be contained and the machine is not even 50 % of it's power, they are getting addicted and horny. 

The aliens need to be ready to push things harder and when the times come shift to the next step of the test : hardcore sex ! 

Enjoy !
