John started to stroke Steve's bulge with his gloved hand watching it grow more and more. Then he reached into his squires backpack and pulled out a couple of transparent tubes. Steve was breathing hard and opened his pants to reveal his fully erect member. John took one of the tubes, which was only open on one side and pushed it over Steve's member who released himself into it in many spurts moaning loudly as a thick liquid glowing bright blue filled the tube. Swapping the tube Steve was able to fill another, then another before finally calming down as John corked the bottles. "What... what was that?", Steve asked, still out of breath. "Well", John replied, "one of your duties is to provide me with rocket fuel". Steve who had already almost made his quick recovery saluted "Aye, sir!", and grinned.
John slotted one of the full tubes into his rocket pack and patted his squire on the head before near effortlessly shooting up into the virtual sky of the desktop background. "Boy I wish I could go as fast", said Steve.
