Emily: The Mistress

I've been screwing a coworker's husband, without her knowledge. They're in an open relationship, so it's OK, but I just don't want her knowing I'm his sidepiece.

I knew he was working from home today, so I texted him.

[I was thinking about sucking you off]

It took a moment, but my phone beeped as I got a response from him.

]Cant talk in meeting[

Great! I decided to mess with him. I glanced over at Sue and she was working hard, then I took a picture up my skirt, then sent it over to Dave.

My phone beeped with his response again.

]Show me that pussy[

Sue was still working when I checked on her. I reached under my skirt, pulled my pantyhose down to my thighs and pulled my panties to the side. I took another picture and sent it to him.

My phone beeped again.

]I can hardly see anything[

"You're getting a lot of messages," Sue said.

"Uh, yeah," I replied, "friends trying to sort something out for this evening."

My panties were still to the side, so I slid forward in my chair so I could get my legs a little further apart, my hose cutting into my thighs uncomfortably. I took another picture and was about to send it when Sue peered over the partition at me. I hit send, then put my phone down.

"What's up?" I asked her.

"Just wondering what's going on," she said.

My phone beeped and we both glanced at it. There was a full screen picture of Dave's dick. Luckily he wasn't in the picture. I turned my phone over so the screen was against the desk. I guessed that he was out of his meeting.

Sue looked at me with a sly smile on her face.

"Ah," she said, "that sort of friend, for that sort of evening."

I sat and looked up at her, feeling my panties all bunched up uncomfortably under my skirt.

"I'll leave you to it," she said, heading back to her desk.

I shuffled around on my chair as I sorted out my underwear.

I decided to take a couple of hours off and our boss agreed, so after wishing her a good afternoon I went to their house and screwed him in their bed. I tied him to the bed and rode him for a while, then untied him and let him go on top until he came. The problem was, we didn't set an alarm or anything. We were still lying in bed, his cum inside me, when she got home from work. Fuck.

"Let me handle this," Dave said, grabbing his robe and going downstairs to head her off before she got to us.

I wasn't really sure what he was doing, but I didn't panic just yet. I lay on the bed and waited to see if I should be diving out the window.

A few minutes later he led her into the room. She had a blindfold on. Interesting.

"Just a sec," he said to her, then came and sat on the bed next to me. He picked up his phone and pointed it at her.

"OK," he said, "take off the skirt."

She unbuttoned her skirt and let it drop to the floor. She stepped back out of it and started to bend over to pick it up.

"Leave it."

She stood back up.

She was wearing pantyhose and sensible panties. She clasped her hands together in front of her.

"Blouse," he said.

She unbuttoned her blouse and slipped it down her arms behind her. She was wearing a big, sensible bra.

"Just drop it there," he said.

She dropped it on the floor behind her.

"Bra."

She reached behind and unhooked her bra. She just dropped it on the floor next to her. Her tits are a lot bigger than mine but I try not to be jealous. I'm getting fucked by her husband after all, smaller tits or not.

"Take your shoes off."

She stepped out of them.

"Hose."

She slid her pantyhose down her legs. It started to pull her panties with it and she pulled those back up. She pulled her feet out of the pantyhose and just left them on the floor.

"Panties."

She slid them down her legs and stepped out of them, leaving her standing there in front of us naked.

She stood upright again and Dave said "hands over your head."

She put her hands on top of her head.

Dave got up off the bed and went and pulled on her nipples, then guided her to the bed.

"Turn around," he said.

She turned around and he had her lie down on the bed. I moved over so she could shift to the middle.

He took her left hand from her head and pulled it towards the loop in the corner. He tightened it up, holding her arm there.

Quickly he did the same with her other hand, then he tied her feet.

"Can you move?" he asked.

She tried. "Not really."

"Good," he said.

He put his mouth on her right nipple, sucking it to hardness. He did the same to her left nipple.

He stopped, leaving her breathing heavily.

"Do you want to swallow my cum now?" he asked.

"Yes."

"Sound enthusiastic," he said.

"Yes!"

"More!"

"YES, I want to swallow your cum!"

"Beg," he said.

"Please let me swallow your cum."

"You can do better than that."

"Please, I'm begging you, please let me swallow your yummy cum."

"OK, if you really want," he said, nodding at me.

I maneuvered myself over her, facing her feet. My feet went under her arms, like we were going to sixty-nine. Holding her head with my legs, I lowered my pussy down to her face.

"Suck my cum out," Dave said. He was still pointing the phone at us.

I pulled on her nipples, hard, and she started licking his cum. I started to rub my pussy on her face and let go of her nipples.

Dave stood on the bed, coming over and presenting his dick to my face. I opened my mouth and let him push it in. Usually this is foreplay for us, as I don't like him cumming in my mouth, but I eagerly sucked it as Sue licked me out.

After a few minutes of me grinding on her mouth, I came, grinding and shaking. She kept licking and I kept sucking Dave's dick until he came in my mouth. As it wasn't that long since he'd cum, there wasn't too much of it and I didn't need to swallow any of it.

Dave backed away from me, and I climbed off Sue. She lay there, breathing heavily. I turned around to kiss her and she kissed me back.

My tongue probed her lips and she opened her mouth. I dribbled Dave's cum into her mouth as I stuck my tongue into her mouth. She swallowed that too.

We kissed for a few minutes longer. I backed off, leaving her tied to the bed.

"Do you want to cum?" Dave asked her.

"God yes," she whined.

He went into a drawer in the chest next to the bed and pulled out a couple of dildos. He bent down and started licking her pussy, then slowly pushed one of them into her. He went to licking her clit until she was huffing through her nose and sounding like she as about to cum, then he stopped and sat up.

He was ever so slowly sliding it in and out of her and he passed me the other dildo. It was floppier silicone and when I took it, he opened his mouth and acted like he was sucking something off. I took his meaning, putting it to her mouth.

She opened her mouth and let it in. I slowly pushed in all the way to the back of her mouth until she gagged. I held it there and she swallowed so the tip went into her throat.

She was breathing hard through her nose and I bent down and sucked on one of her nipples.

I could see Dave had brought his tongue back to her clit and it wasn't long until she started to cum, twitching and shuddering.

We left her there to recover, tied up blindfolded with the dildos in her, and I got off the bed and got dressed.

Dave walked me downstairs and let me out. He leaned in for a kiss and I turned my face.

"I don't think so," I said.

He grinned at me.

"So long then," he said.
