It was also the second time I had sex with my friend's wife.
Alan had come back from Florida and they had gotten a small one-bedroom house in town. I had a falling out with my parents just before I joined the Marine Corps and they had asked me to move out. I was visiting Allan and Kim and luckily they had asked me to stay with them. I took them up on the offer.
Allan had gone to work and Kim asked me to take her to the grocery store. I agreed because I wanted to pay for the groceries since I was going to be staying with them for a little bit. As we walked down the isles getting stuff, I kept staring at Kim, she was looking good in her jeans and t-shirt. She didn't have a bra on, so I was especially enjoying the view of her nipples poking though the fabric. We were in line to pay and she didn't want me to pay, but I insisted since I was a guest.
We got into the car and she turned to me and said, "I saw you looking at me in the store." I replied that yes, I had indeed been staring and that I enjoyed what I saw. I noticed a small smile when I said that. I told her that I missed having fun with her and said that I'd love to have fun with her again sometime. I was feeling more bold, and while I wanted to have sex with her again, I also knew that with Allan at home, it probably wouldn't happen.
One night after a lot of drinking and listening to music, Alan went to the bedroom with Kim. I heard them clearly having sex. After a few minutes, Kim came out and asked if I wanted to join them, I politely declined, I had only had sex once before (with her no less) and wasn't convinced that it had been Alan's idea. I lay on the couch rubbing my cock through my underwear listening to them as I drifted off to sleep.
I wasn't sure how long I'd been asleep when Kim startled me away, by standing over me in a sheer pink negligee that had one button. It didn't conceal anything! I reached up to grab her breasts and she liked it. She said Alan was knocked out and that if I wanted, we could have a little fun. My thoughts turned to the shotgun he kept behind the door. She asked if I had a condom, I told her no. She said she had some spermicidal gel and that she would use that if I wanted. I told I had no idea what it was, she said it was basically a form of birth control. She said, just so you know, it will be very slippery. I told her I liked slippery things. More importantly, it would be skin on skin... another first for me.
