"Don't ...don't do... th-that!" Melissa whimpered as Sebastian's finger began slipping deeper into her ass. "Oh, no! Oh, please no! D-don't! Ohhhhhhhh...hh!" Sebastian's finger was buried in Melissa's ass, moving in and out of her while his dick did the same in her snatch. His tongue was flicking rapidly over her nipple as he sucked her breast deeply into his mouth. His free hand was squeezing her other breast. He was handling her in such a way that she was starting to feel as if there were more. Sarah was a hot bird with long passionate kisses and soon my cock was standing proud straining my trousers to be released and she was rubbing it to make it even stiffer. “I,ll just release your cock!” Sarah stated the obvious and unzipped my flies then guided it through my boxer shorts into the open. As the nearest couple were some distance from us and appeared to be having a passionate snog she grasped my hardness and let her delicate fingers work up and down my sensitive shaft. In the mean. She found that a strange organ on one of the moderate size animals was chock full of potassium chlorate. Don't ask me how it got there, but I was not going to complain. This was as powerful an oxidizer as potassium nitrate and should work very well in a version of gunpowder.Our diet was a little monotonous for a while as we concentrated on killing enough of those beasts, which we called "oxy," until I had enough potassium chlorate to begin experimenting on a black powder formulation. We mashed. By the time I finished with the whip, shehad some beautiful marks on her ass and thighs, almosta work of art, she was breathing heavily, and neededsexual release, but it wouldn’t be offered to her yet.I unchained her wrists from the ceiling, and put thechains from the nipple clamps around her wrists infront of her, her hands were at her waist and if shepulled hard on her nipples she could just barely reachher clit with her fingertips. I told her that I wasgoing to use the crop on her ass.
