My girlfriend and I were together for a long time before I met with Amanda and her husband. I had known Amanda before because she was good friends with my girlfriend but I had not actually really gotten to know her well until after she was married. After I met Amanda's husband we decided that we would all hang out and find something fun to do. What we usually ended up doing was watching a crappy movie and talk the rest of the night. Many times we'd discussed our sex lives and I quickly learned that Amanda had an insatiable sex drive like myself. My girlfriend had zero sex drive and Amanda's husband was very similar and it become a running joke that we got mixed up and I should have been with Amanda.
My girlfriend eventually got a new job and had to work Saturday mornings so she didn't want to be out on Friday's so she wouldn't be tired for work.
Amanda's husband and I had become very good friend and he invited me to come over on Friday's since my girlfriend wanted to rest. I would usually spend a few hours with my girlfriend on Friday after work and then I'd head over to Amanda and her husband's house to do some drinking and hang out. After a few drinks I'd find myself getting extremely horny and of course the only woman around was Amanda. When she lounged around the house she would usually wear skimpy shorts that pretty much only hid her most sensitive areas. Over time I found myself more and more attracted to her and was having some serious fantasies. There were many nights that I masturbated to the thought of giving her the pleasure her husband wasn't, and satisfy my own desires that weren't be taken care of. I even got daring enough to grab a used pair of Amanda's panties from the laundry and wrapped them around my cock to masturbate with. What didn't help was we were continuing to talk about our sex lives when my girlfriend was over and I would hear some of the dirty things Amanda enjoyed doing. I also got to hear that Amanda likes to masturbate many times a day. My girlfriend wasn't the adventuress type and rarely wanted to try anything besides your standard missionary and that was about all the sexual contact she wanted.
One Friday night while Amanda, her husband and I were watching TV I had the feeling someone was staring at me and I finally noticed out of the corner of my eye that it was Amanda. When I would turn to look she would quickly change her glance to the television. I wasn't sure if it was just me wanting it to be true or if she really was staring at me so I mentioned it to my girlfriend. I wanted her to confirm what I was thinking and it would also show her that she could trust me because I was telling her, which was just a way for me to get the information I really wanted. After a few nights with the four of us together my girlfriend did confirm that she was starring at me and she apologized with a laugh. I guess the weekend before Amanda began starring at me Amanda and my girlfriend had discussed our sex lives more in-depth than we normally do as a group. My girlfriend had mentioned to Amanda that I always take care of her first before we have sex and always make sure she is taken care of during sex and if not I take care of her afterwards. Amanda was shocked by this because her husband normally gets his and rolls over to pass out, leaving her to pleasure herself or leaving her frustrated and she thought all men were this way. I also learned that their marriage wasn't doing well and she wasn't happy with the way things were going. This was an even bigger turn on for me knowing that Amanda was possibly starring at me because she wanted to explore with me sexually, their marriage is on the rocks, and my girlfriend thought it was cute.
A few more weeks passed of regular Friday night drinking and I could still sense she was starring at me. Her husband had a tough week at work and decided to drink to the point where he was ready to pass out around ten o'clock. We were all watching TV at the time and Amanda and I decided we weren't tired and would stay up for a while so her husband wobbled down the hallway to their bedroom. I always sleep on their couch when I stay there and I was pretty drunk myself so I stripped down to my boxers and crawled under the blanket. After about 15 minutes I felt that I was being watched again and out of the corner of my eye I could tell Amanda was looking in my direction. I also noticed a slight movement near her lap and when I took a quick look I could see that she had her hand slipped up the leg of her gym shorts moving back and forth. I watched her hand move under her shorts out of the corner of my eyes for about five minutes until she pulled her hand out and stuck one of her fingers in her mouth and slowly pulled it out. She then jumped up and went to the kitchen to get herself a drink and probably adjusting herself. When she came back she jumped into her seat on the other couch and had a large smile in my direction. I figured the show was over for the night so I covered my eyes to try and get some sleep.
