The sounds of the winch turning slowed. Joanna felt the tension building inher legs, her back and her shoulders, as the short lengths of chain that fa...tenedeach of her ankle cuffs to the floor were stretched taut. They were stretchingher tighter than they had before. Her head was pushed into a chin down positionas her arms were stretched. She felt fingers tracing the muscles in her back, her buttocks, her legs. "Ok," a voice she recognized as Gilbert's said. "That shoulddo it." The hood was. She dug her fingers into my ass cheeks. "Harder Jude! Fuck me!" She screamed and I did just that, I started to slam into my sisters virgin pussy, over and over again, she screamed at the top of her longs "oh Jude, JUDE FUCK! I'm cumming don't stop!" I felt my balls tighten as they slammed against her pussy. "I'm cuming too! Fuck" I yelled, after a few more pumps i pulled out and cummed on her stomach I collapsed ontop of her both of us trying to catch our breath . "That was amazing sis" I. "Babe, we've only got an hour. I know what you need." I was already naked. I rolled over and got on my hands and knees after I handed him my lube and a rubber. He knew what I wanted. His big cock pounding my twitchy ass for the next 40 minutes until we had to get dressed and back to work.Big Michael (as I called his huge manhood) was ready. Dr. Michael rolled a condom on his cock and he thickly swabbed my hole with the lube. He was ready to take his frustrations out on my ass. He plunged right. I went out to see what she needed and found that she wanted me to oil her back. It was all I could do to not cum in my pants as I rubbed oil into her gorgeous tanned skin. I kind of lost track of time and realized that oiling her back was becoming something more of a massage. Terri finally said "I think ya got me covered," and gave me a wink.I went right back into the house and used my oiled hand to rub out an amazing orgasm.This oiling became a daily ritual throughout the summer, as did.
