I never expected anything would happen, but the workload in our area spiked last fall and opportunity arose.We both had to work one Saturday. As it tu...ned out, we were the only ones in the building for the day. She was wearing a tight, white button up top that easily revealed her lacy bra and its abundant occupants. I could see through the gaps between the buttons, the blue veins threading just under the light brown skin on the insides of each. The blouse also kept riding up in the back to. He closed the blind again and I stood there – even though my cigarette was now out – waiting and wanting him to open that blind again. I've never in my life considered sex with another man, nor was I really considering it now, but I wanted to see his hard dick. I wanted him to open the curtain and jack off until he shot cum onto the window. I wanted him to show me that hard cock. What I wanted was to pull out my own hard cock and jack off with him; at no time did I consider sex with him, just. When I finally got to her pussy I kissed her lips and clit. She let out a big moan. I couldn’t believe I was going to be the first guy to go down on her. I circled her clit with my tongue and flicked it gently. She was starting to move her hips and thrust her mound into my face. I started running my nose up and down between her lips while licking them. She got more into the action as we went along. Soon her hands were on the back of my head pulling my face in tighter. She got extremely wet. It was amazing. Slowly she began thrusting again, then a little faster. Soon she was humping like mad and came with a scream!. I held her hips and kept thrusting myself and she kept coming and coming --at least six times before she rolled off exhausted. I was not done yet though. I rolled her onto her belly, shoved pillows under her waist so that her beautifull, tiny little behind was up where my cock could reach it. I slid into her cunt and began to pump slowly. She moaned and churned.
