True Story Sex Story: Chapter 10: Tuesday - The 5th in my Infidelity series about how I cheated on my BF, got involved with with the guy I cheated with for 6.5 months and what started as a mistake, became an affair and then slowly turned into my loss of self and degradation. This 5th story takes place about a month after I first cheated in what was the "happy time" but I was already seeing the control and training taking place. Be sure to read the previous stories for this to make sense.

On Tuesday I had barely sat down at my station and pulled up the chart of a patient I needed to see when the first text arrived.
“I keep thinking about your delicious ass. I want a picture when you get to work. One finger inside. Then, if you can take it, two. Do not overthink it. You overthink everything, and it has not saved you yet.”
“That is slander, accurate slander, but slander nonetheless. Give me twenty minutes. I have to look like I care about other people’s problems first.”
“Twenty minutes. Then I want you in that bathroom thinking about my thumb.”
He then sent a picture I did not know he had even taken, me on my hands and knees on the living room rug, him behind me mid-stroke with his thumb buried in my ass. It must have been the moment I had cum because my head was partially turned so you could still see most of my face with my mouth wide open in a scream of pleasure. I felt the wetness immediately begin to form between my legs. This was getting ridiculous; I would have to start bringing extra pairs of panties with me to work at this rate, as by the time the day was over, the pair I was wearing would be a hot, steamy mess.
There was no reason to bother trying to argue my “exit only” defense again; I had his tongue in there multiple times, as well as both his and my fingers up there recently, so trying to claim I was some anal puritan at this point was not going to fly. I knew where this was going. I am not a totally blind idiot. I had seen how he works; he gets me to agree to do one thing, comparing it to another thing I have already done, and then gets me to do that. The next time he will ask for something else that moves me closer to his goal, and in this case, I knew his goal was to ram that big cock of his in my ass. I understood the game now, and given how much I enjoyed both his tongue and then his thumb, curiosity now had me leaning towards letting him have his way, but I would still put up a fight and not make it easy on him. If he wanted my anal virginity, he would have to work for it.
Twenty minutes later, I was closing the door to the same bathroom and engaging the lock. My pants came off, and soon I was leaning forward, phone in one hand, while I worked a spit-covered finger into myself with my other hand, while trying not to resemble a training video no workplace should ever produce. It burned, then it did not, then it made my knees feel unreliable. I took the picture and sent it. I hated the little sound I made when his reply came in.
“Look at you. My dirty girl at work with a finger in her ass. You are soaked.”
“I am going to walk into oncoming traffic after this, but I will at least try to do it professionally.”
“Don’t do that. I like your legs, especially when they are behind your ears or around my waist. Now take another picture and try two fingers. I would like to see them going in and then buried as deep as you can make them fit.”
“You are unwell.”
“And you sent the first one with your vagina looking like Niagara Falls. Do not pretend you are the reasonable adult in this conversation.”
