Work in my area had picked up and was holding a steady pace, which required myself and one assembler to work every Saturday for at least half a day. There were three assemblers who rotated - Maria, Ming, and Brenda. Maria I’ve already told you about. Brenda is nice, but nothing sexy (to me, at least) and rather strait-laced. Nice to work with, but nobody I’d watch walk down the hall. Ming, on the other hand, is. Chinese, short with a bit of a belly from childbearing, but she still has a waist, nice tits, and a great ass. She’s about Maria’s age, fifty-ish, but she hasn’t got that “rode hard and put up wet” look that Maria has. She can easily pass for late thirties/early forties.

Maria and I had worked out a system where we would arrive about an hour early to give us time for some serious fucking and still get our 4 hours of work done. We fucked first, then punched in and went to work.

This Saturday, though, Maria was late and looking a touch rougher than usual. She’d partied a bit too hard the night before and had overslept. No problem. She still got my dick hard as a rock and that was what counted. We were back in our little room, had done some 69, and now she was bent over the bench as I slammed my dick into her from behind while my thumb pumped in and out of her ass. As usual, her juices had soaked my balls and thighs, dripping down to puddle on the floor between our feet. She was approaching her third (or fourth?) climax and was squealing like a scared pig interspersed with Mexican words. I was closing on my climax, too, and was wondering where to do it - pussy, ass, mouth???

Then I heard something behind, almost like a whimper. Dear God, my heart stopped right there! Glancing back, I almost jumped out of my skin. There was Ming, standing in the door, lips parted, a glazed look on her face, her left hand steadying her on the door frame, her right hand working furiously in her loose pants. OK! No problem there, obviously.

I asked Maria, “What would you do if another woman was with us?”

She replied, “Filthy gringo. I’d eat her pussy while you fucked me.”

“Would you eat Ming’s pussy?”

“Fuck, yes! Why? Gringo got a thing for Chinese pussy?”

“Gringo got a thing for any pussy, but Ming’s watching and about to cum on her finger.”

“WHAT???” Maria bent around so she could see behind me and her eyes got as big as saucers. “Fuck! Ming, get your clothes off, girl. Don’t waste your juices on your finger.”

That seemed to pull Ming out of her pre-orgasmic trance. The reality of her standing there about to finger herself to orgasm while watching us fucking at work hit her and her face turned bright red. “I should go,” she said in her barely decipherable Mandarin accent.

“Get out of me, gringo,” Maria said as she started to straighten up and face Ming. I backed up a bit and my dick slid out with a faint slurping sound. I was standing there with a raging hard-on, Maria’s juices and my pre-cum dripping from the tip. Maria walked over to Ming, grasped Ming’s right forearm, and gently pulled her hand from her pants. Lifting Ming’s hand, Maria proceeded to clean the pussy juice from Ming’s fingers, sighing and moaning as she did so (a little overboard, I thought). Ming watched wide-eyed. Maria then placed her own fingers into her pussy, saturated them, then offered them to Ming. Ming looked at the soaked fingers, then at Maria’s eyes, and opened her mouth. When the middle and ring fingers lay on her tongue, Ming closed her lips around them and sucked them clean. “More,” she said as she slipped her fingers into Maria’s pussy, then licked them dry.
