After Rachel's revelation about her and Kathy, and then Rachel and my wife, I was shell-shocked to say the least. I asked Rachel how long this had been going on and she said "Only about five years." You could have knocked me over with a feather.
I looked at her and said "This is most every man's dream, to watch his wife and another lady he knows making love. And this has been going on for five years and we didn't know?"
"Yes" she replied, "and you can never let Kathy or your wife know until I have had a chance to talk to them about what you have seen and heard. And Daniel doesn't know the whole story either."
This had me turned on so much that I picked Rachel up and carried her to the bedroom where I laid her on the bed and pushed her skirt up to reveal her sexy white thong with a huge wet spot in front. I pushed my tongue against her thong and wedged it tight inside her, tasting her juices. She was getting wetter by the second, so I placed my thumbs in her waistband and pulled the tiny string down her thighs to get better access. I inserted a finger in her warm tunnel and clamped my lips on her clit, sucking hard. Rachel grabbed my head and pushed me tighter to her pussy. I inserted a second finger and turned both up to reach that rough spot under her clit. Rachel screamed "Oh my God, don't stop. It feels so good! Please don't stop, don't stop, oh fuck please finish me off!" I inserted a third finger and she gushed out around my hand, soaking my face. As I pulled back and looked up at her face, she grinned and said "I have never cum that hard or that long in my life. You have to do that again before you leave."
That brought up the subject of the next two days and what might happen. I said "Tomorrow should be decision day, and I have to be in region by 1000 for any last minute questions before they go into session and make a decision. So I should be back by 3:00 PM at the latest."
Rachel replied that would be good because she and Kathy had a high tea at 4PM and would be done at 4:30, so we could meet at 5 for dinner. I agreed that would work, and maybe we would have something to celebrate then. It was getting late so we decided to clean up and get a good night's sleep. After a lingering kiss good night, I headed off to the guest bedroom.
I was awakened by a warm body sliding under the covers, and rolled over to find Rachel naked beside me. I took both her breasts in my hand and rolled her nipples between my thumb and fingers, pulling them out and making them stand proud and erect. I lowered my mouth and took one in, sucking it lightly and running my tongue around the pointy end. Rachel moaned and grabbed my cock, pulling me up over top of her. As I slid over her thigh she tucked the head of my cock into her wet pussy and begged me to fuck her hard and fast. Sensing she was so wet, I just plunged all the way in on the first stroke and Rachel screamed "Oh yes, that's what I need right now. Don't go easy, just fuck me like you own me." Not wanting to disagree, I just kept plunging in and out, going faster and harder as I became more attuned to her moaning.
After what seemed like no more than a minute or two, I felt Rachel's pussy clamp down on me so hard I thought I might break in two. She went limp under my body, and her pussy kept clamping and releasing my cock. Finally I could take no more, and dumped my cum way up inside her. As I laid down on her ample chest Rachel looked up and said "I just had to have one more time with just us. This afternoon, if all goes well, we'll probably have our first threesome."
I replied "Now you have me wondering who will be joining us. After watching you and Kathy rolling around yesterday, I hope to get a taste of that little fiery redhead."
Rachel said "You never can tell." I grabbed her and led her into the main bathroom, turning on the dual showerheads and pushing her in ahead of me. I stood behind her and lathered her back, reaching around under her arms and soaping those half cantaloupe sized titties. I let my left hand drop down and scrub her pussy, making sure to pay homage to her thick clit. Rachel took hold of the grab bar and pushed back, saying "Put it in, you've got me so wound up I need your cock. Stop playing and just fuck me." So once again I just pounded her as hard as I could go.
After we finished and dried one another off, I got dressed and headed out to see what my future would hold, The entire drive all I could think about was how I hoped this could be at least once a month and maybe so much more. Rachel sure had fucked with my mind in bringing up a threesome this afternoon.
