Keeping My Clients Happy

Every work day I visit my regular clients.
They're all males, over sixty, with some requiring more assistance than others.
I work a six day week (My choice) not getting paid for my Saturday or Sundays, whichever I choose to do any particular week.
The reason I choose to do so, is because I make my special visit to one of three men I'm having sexual fun with.
During the week I get around an hour and a half with each client, the vast majority just requiring help around their homes.
However three of the men enjoy having me suck their cocks, with two of them also taking advantage of my rear hole.
During the week it has to be a quickie, but at the weekend we can take our time and both men who enjoy anal sex, love getting me naked on their beds and fucking the shit out of me.
I visit them alternatively each weekend, and yesterday (Saturday) was Sam's turn, having taken Daves cock up my arse for a quickie on Wednesday ( It was a quickie too. A couple of minutes in his kitchen with him shagging me over the work top).
Yesterday Sam was already fully erect when I arrived, and my clothes were off within a couple of minutes.
However we didn't go to his bedroom as we usually do. No, Sam had me lean over his coffee table in his conservatory after I'd spent an age sucking on his six inch cock.
He told me afterwards he'd taken a little blue pill, and boy did he fuck me yesterday. He plowed my arsehole for over twenty minutes and given Sam is over seventy years old, his stamina was amazing.
Finally he came up my arsehole and stayed in me for a while taking pictures on his phone of his cock buried up my arse.
Then he asked me to look up and to my right.
Looking directly into his conservatory was a neighbour of his, an older male neighbour who was clearly wanking.
Sam told me his name's Derek, he's divorced and he's into younger men.
Ten minutes later in Sams lounge, I sucked off his neighbour and let him cum all over my face.
I'm going to do a double next weekend, that is if Dave doesn't want to fuck me during the week. That's because I've agreed to entertain both Sam and Derek at the same time.
