I won't go in to all the details about the mornings events, its safe to say we arrived in the car park at our usual time of 08:20 and parked up where we had for the last two days; Fiona was again braless and sitting in the back of the car with her blouse undone and her big boobs naked. She was sitting behind me but sort of facing the rear door behind the passenger door with one leg in the foot well behind me and the other up on the chair just in front of her at a 45 degree angle. Her shorter than normal skirt I'd chosen for her to wear for work was pushed right up and her black suspenders and matching thong were on show.
We just needed Mark to arrive.
On the dot he swung in the car park and pulled along side me smiling as he exited his vehicle.
My window was already down and I told him to get in the back on the far side.
"Ok," he said walking round and opening the door and sliding in next to his open legged and bare chested manager.
"Good morning to you too Fiona," he said admiring his greeting with a massive grin.
"Morning Mark," she said shuffling over a little and moving her hands to his belt buckle without any hassle from Mark.
Mark's grin somehow got even bigger when he knew what was happening and once Fiona had unbuckled his belt and opened his trousers her pulled his shirt out and unbuttoned it. Mark had a firm chest and toned stomach so must've worked out a little but I was just as eager as Fiona to see what would be using her mouth and with a pull and yank Fiona had his trousers and boxers in a heap round his feet.
"May I sit another way owner?" she asked and of course I told her to get in the best position possible.
She spun around and got on her hands and knees pointing her arse at the window and hovering her head over Mark's rapidly swelling dick.
His cock was pretty decent and I guess at about 7" with a nice girth, similar to the purple dildo in length and width; but where the dildo had a pointy tip he had a large pink dome and two big veins running the length of his shaft.
Fiona then reached out with her slender smooth fingers and gripped her assistants cock for the first time.
"I've waited for this day for a long time Fiona but even more so since Monday," he said leaning back against the seat.
Marks cock had swollen to it's maximum length in her hand and she closed her fingers and thumb tight around it and jerked it a few times before she lowered her head to within half an inch of his helmet.
Mark couldn't help but let out his own little yelp as he felt the wetness of Fiona's tongue circle his helmet before she dropped the tip of her tongue in to his japs eye.
"Oh shit!" he gasped.
But Fiona's tongue was gone and she was now licking down his shaft around his shaven balls, I knew what he was feeling now as Fiona was an excellent cocksucker and his eyes closed shut told it's own story.
She spent a good five minutes working her tongue round his helmet, shaft and balls making sure she did a good job on him and lubricated his pole all over, she then lifted her head and hovered it over his throbbing cock for a moment watching it twitch freely as she had taken her hands away.
Mark opened his eyes at this point to see where Fiona had gone.
Fiona lifted her head and looked at Mark and said , "This is for making you cover for me Mark."
And she sunk her head opening her mouth at the same time and taking his helmet and shaft in her mouth and down her throat in one continuous motion until his cock hit the back of her throat and she gagged before coming up for air.
She caught her breath and then put her lips round his helmet and closed her lips tight as if it was a cunt and then she lowered her mouth maybe four inches peeling his foreskin back at the same time and then pulling back up.
She then gripped his cock with left hand right at the base and keeping his foreskin peeled right down and then she began to give Mark one of her tight wet expert blowjobs that I can vouch for.
She had a good twenty minutes to milk his balls and I knew only to well without even looking at Marks screwed up face that he'd do well to last over ten minutes; I turned myself in my seat to get a decent view of her head and mouth working on his pole and then turned on the video camera on my phone to get the seedy scene on tape.
Neither of them saw me doing this as Fiona was engrossed in milking Marks balls and he hadn't opened his eyes since her mouth swallowed him, so for the next twelve minutes I was able to record Fiona whoring her mouth out and capture the moment when her assistants cock twitched and I knew he was ready to unload.
"I'm gonna come," he said opening his eyes to look at me not even registering the phone recording, or not even caring, "Where can I come I'm really going to come soon," he said as his cock twitched again and he pushed his groin up sending his meat in to Fiona's mouth quicker than she expected.
"Come in her mouth Mark and she'll swallow your come like a good whore, isn't that right whore?" I asked after telling Mark he was free to unload in her mouth.
"Mmmppphh ummmpphh," she mumbled not missing a beat as she prepared to taste his cream.
"Here I come Fiona you naughty bitch, swallow my come you cocksucker," he said holding her head down with both hands as his dick pulsated three then four and five times as I recorded her cheeks bulging.
Eventually her cheeks returned to normal size as she swallowed his load with his dick still firmly wedged in her throat.
"Show Mark that you enjoyed his come whore," I told her still recording the action.
