"So don't disappoint me baby! I WILL be listening! Now... hang on, I'll be right back."Once again there were a few minutes of silence as she'd placed ...e on hold. I really hadn't been doing anything, but suddenly the thought of that was extremely arousing to me. Especially knowing that she WOULD be listening while actually engaged and participating in some sort of business meeting."Ok sweetie, my ear piece is in. And I'm just now entering the room. I won't be able to say too much, but as I told. They were all slim and between 5'8 and 6'2". The three mechanics, Roger, Tom and Bob had been working for several hours and were covered with grease and grime but had not stopped to get cleaned up. Donna looked at them in disgust. Dave stepped in front of Donna. "OK lady, let's get you out of those clothes." He reached for her blouse and began unbuttoning it. Donna stood there passively, not helping but not fighting him. He pulled her blouse back over her shoulders and she let it fall to. “I want his cock” Sharon declared. “Are you sure darling?” asked Allan. “I have never been surer in my like. I want him to fuck me” and without she got on her knees, leaned over the bench and yelled “mount me now”.True to my training the lab mounted her and I was relieved then he found the warm embrace of her pussy without any help. She squealed as he found the target and proceeded to do what came naturally. She moaned and groaned as she was fucked like never before. I suspect no human could be. You are always Master’s slut. Get that through your slut brain!” I quickly unfastened the bra and tossed it on the floor. I put a clamp on her left nipple and saw Linda’s face wince in pain. A few seconds later I clamped her right nipple. Linda gritted her teeth but did not say anything. Then I attached a small chain from each nipple clamp to the O-ring on her neck collar. Now I could pull either or both chains which would tug on either or both nipples. This action usually got a slut’s.
