In space, the engines were pure rockets, using advanced aerospike technology to produce thrust. At Mach three and faster, inlets at the front of the e...gine pod were opened, and the engines converted to scramjets, able to propel the shuttle to speeds in excess of Mach fifteen at the edge of space. At lower altitudes, high efficiency fanjet sections were used to gain enormous fuel efficiency below twenty-five thousand meters. This combination of propulsion technologies allowed the shuttles to use. That was kind of cool, I mean, they trusted me with a key to the house, but I couldn’t stay late after school or anything because then Jack and Bobbie Joe would be locked out of the house. I did miss the bus once and had to run home, about three miles, and Mom threatened to take the key away and make us stay with Mrs. Wrybel across the street if I did it again. Mrs. Wrybel had never smiled once in her life! No way did I want to stay with her!In any case, we got used to Matucket Middle School. He had found someone. That could solve that problem. Unfortunately, as sometimes happened, it created a whole set of new ones."Does she know about us?" she asked. Zak looked a little uncomfortable."She knows I'm from this area, and I said I lived with my family. That's about it."There was probably more, she suspected, although there was not much more to know. Zak was not one to lie, conceal. If he'd been talking to her for weeks, details would have come out. He looked between them."I didn't. Then I again carried her back to bed and started licking her pussy madly. She was moaning heavily and pushing my head towards her pussy. Then she said “now it’s my turn”. And she went to downwards and held my monster in her hand; started stroking it. It was already with pre cum. She kissed on it. I was in heaven!!! She said “You have really nice taste bro”. She took it in her mouth and started sucking it. She was doing her job slowly but good. I was moaning in pleasure. She increased her speed.
