I never thought I would have a story like this to tell, but since I do I am more than happy to share. First I should start with a little about myself. I am a very average looking guy. I'm short (5' 7"), fat (250 lbs) and being of Irish descent not endowed with a large penis (7"). I work in the Boston area with a great group of co-workers. Although I am straight several of my friends from work happen to be gay. Through these friends, I was invited to play in a volleyball league sponsored by a local gay rights group. Strangely enough that is how this story starts. There are about 100 people in the league. There are about 60 gay or bisexual men, 40 lesbians and 2 straight men including myself (the league proudly calls us heterosexual supporters). The league has 3 "seasons" per year- Winter, Fall and Summer. Although the Winter and Fall seasons are played at a local YMCA, the Summer season is played at a gay club outside the city. The facility has sand volleyball pits, a large clothing optional pool, lockers, showers, outside bars, nightclub, game room, dinning room, etc. At the time of my first Summer season, I was 35, finishing up my divorce and I only had my daughter every other weekend. On weekends that I didn't have my daughter I would often go to the club on Saturdays to watch the other games and hang out with my friends. As you might guess, not many straight guys were at a gay club all day Saturday, but there were many straight women (fag hags) and the food and drinks were very cheap. Many of the women (gay and straight) would sunbath topless or nude, so the view wasn't bad either. It was on one of these Saturdays that I was approached with one of the most startling offers of my life. One of the better players in the league is a woman named Amy. Amy was 28 at the time. She is about 5' 9" and extremely athletic (she was the team captain of her volleyball team in college). She has shoulder length, light brown hair, brown eyes and an unbelievable body (especially her ass). Amy had made me her pet project when I first joined the league and was on her team. I was so bad that she decided I needed extra practice. Even after the teams were changed for the next season Amy would still practice and scrimmage with me before and after games, especially on Saturdays. We would also go out to dinner or to the movies with her partner Liz, who is 2 years younger than Amy. So I wasn't surprised when, Amy came up to me after my game and asked if I was busy. I assumed that she had seen how bad my serve was during the game and was going to offer some friendly coaching. I told Amy that I was free for the rest of the day. "Great!� she said, "Let's grab a drink and sit down." And off we went. I still didn't think anything of it when she walked straight to a small table in the far corner of the pool area. When she got there she sat down next to Liz. There was one other seat at the table and there was a pitcher of beer and 3 glasses on the table. Amy motioned to the beer and said "Help yourself." which I did. Liz is a great person but I little on the wild side. She is about 5' 3" with a great body that had curves in all the right places. She has died black hair which she keeps really short. She has many tattoos and piercings and on days like this when she was wearing a bikini you saw just how many she had. The most shocking tattoo she had was a bright blue and yellow dragon that started on her left leg and stretched up her ass onto her back and down her right arm. She also has piercings in her nose, eye brow, belly button and (as I discovered today) in both her nipples. I had barely taken a sip of my beer when Liz looks at me winks and says "So what do you think!?� I replied "About what?" Amy then looks nervously at Liz and says "I haven't asked him yet." Well at this point I say "Well ask me now?" Amy stairs at me for a few seconds and then takes a deep breath. She then looks me in the eye and starts talking very softly and slowly. "Rob, Liz and I want to ask you for a favour. A big favour and I don't want you to answer right away. I want you to think about it. And if you are in any way uncomfortable then I want you to just say no." I laugh and roll my eyes and replied "Amy, unless you need a kidney you really shouldn't be this nervous to ask me for help. and if you do need a kidney well that's why I have 2, so just ask me." Amy laughed a little and then looked at Liz. Liz looks at me at says "Rob, we have decided that we want to start a family." Now that they had my attention. I thought for a couple of seconds and said, "Well, you guys have been together for almost 3 years and you both are great with my daughter, so I would certainly be willing to be a sperm donor. I would just have questions about what role I would have after the baby was born." Liz had this funny look in her eyes as I was talking and Amy looked more nervous than before. Amy was the first to talk "Well, we would both want you to be a part of the baby's life and we would want the child to know you are their Dad when they get old enough to understand. I guess I figured you would be "Uncle Rob" until then. But I don't think we have done a good job in explaining everything." I nodded my head and said "Well, I was wondering which one of you was going to get pregnant" "Well," Liz said, "We were going to let you decide that. But more importantly, we are not looking for just a sperm donor. Our insurance won't cover artificial insemination. We were hoping to do this the old fashion way." Now I was really shocked, but I tried to stay as calm as possible. "OK. So you want me to ..." Liz finally had had enough of talking in riddles. "Simply put. We want you to fuck at least one of us every month until we are knocked up. You can fuck me, you can fuck Amy, you can fuck both of us. You can fuck both of us at the same time. You can pretty much do whatever you want so long as it�s the right time of the month." If you are interested in my response and the rest of the story then please vote and leave comments.
