It was the giant sized red rubber cock strapped into her black harness that pulled my eyes from her perfect round firm breasts, full hips and slim wai...t. “Good boy; you are obedient” She said, as I assumed the doggie position.She slapped my ass hard and I jumped a little in surprise and she laughed and tossed the lube between my buttocks as she turned to the mirror. “Oh, you are enjoying what you see?” She asked, as she reached up and cupped her round perfect boobs. Her nipples immediately. Thenagain, maybe they'd have overpowered me, and things could've been a lotdifferent, for both Jenna, and I. I shuddered at the thought.As if on cue, Michelle knocked on my door. Letting herself in, shecommented "Didn't waste any time changing, did you?" Why did you let yourself in? I mean, what if..." If there was a 'what if,' you would've locked the door, am I right?" So, what brings my newly interested sister into my room?" Exactly. So, how did it go?" That wasn't an answer, but okay. We had. So when she said she had to go I encouraged her to, assuring her that me and the girls would be ok while she was gone and not to worry about us. So she left on the first plane that she could get tickets for. The first couple days were easy – it was late Friday night when she left and so me and the girls had the weekend to spend together. I tried to make it an ‘adventure’ for them so they wouldn’t know anything was wrong. That was one of the main reasons that me and Amy didn’t want to girls to. She knew the drill and began cleaning them up and shaping them to weld them. She used the compressor air hose to clean off any debris around the cleaned area. Next she set the pieces at an exact right angle using a square to check and picked up the wire feed, pulled down her hood, and hit the piece twice, tacking it. She re-measured with the square, just like I taught her and with a perfect touch drew a very slick, low, bead around the piece of pipe.Just like a good tech, she took the hood off.
