This category or "Gay" would have been appropriate for something which has been going on nearly twelve months, but now I genuinely think we should stop.
When my fiancee and I announced our engagement, her father Michael and her mother Ann invited me over to see them. At the time I didn't think it strange, even though their daughter, my future wife was going to be away that weekend. I just thought it would be a good chance for all of us to get to know each other better. If only I knew then what I know now.
No sooner than I'd arrived and sat down on the couch, Ann disappeared for about five minutes upstairs and then walked back downstairs and into the lounge totally naked. Looking at Michael, he smiled, looked at his wife and then said to me "Fuck her if you want my daughter". Now I don't know about you guys, but this sort of thing generally doesn't just happen to me. So even though Ann is a very good looking woman with a great figure, I still questioned what the fuck was going on. Michaels simple reply to me was "Look it's easy, you fuck my wife and (he left it hanging) you get to marry our daughter with our complete blessing".
A minute later I was on my back staring up at a very wet looking pussy and began licking it, as Ann was sucking away on my rising cock. She really knew how to suck cock and before long I was thrusting my hips upwards and fucking her mouth. I couldn't see Michael, but I thought I knew he was watching his wife suck my dick. That was until as my cock was still being sucked so expertly, I heard Ann say "Maybe it's time you let him fuck me". That's when I knew it was Michael who was sucking my cock. There was a "Uh huh!" and my cock was left to sway as Ann got off me.
Kneeling up against the seating of the couch, she turned around and told me she wanted me to fuck her bareback. With Michaels full agreement, I moved over to where she was prostrate on the couch and put my saliva covered cock to her pussy opening. In one long hard movement I sunk my cock into my fiancee moms c**t. It felt so good to have my throbbing cock up her pussy, so I began to hammer away at her as she backed onto me. Building up a steady rhythm we were fucking one another when I felt a hot tongue probe between my ass cheeks. Each time I moved almost out of Ann's delicious c**t, her husband licked and probed my asshole with his tongue, and it began to feel amazing. So good in fact I told him how good it felt.
It spurred Michael on to do something which kick started everything which we now indulge in. Michael wet one of his fingers and without warning me, thrust it deep up my asshole. I didn't have time to protest as my orgasm began to build up. But before I could let them know I was on the verge of cumming, I felt my asshole splitting apart as Michael exchanged his wet finger for his long hard cock.
I was stil inside his wife's pussy and my cock was throbbing with the need to cum, but when Michael began to fuck me, my need subsided. But only for a short time until my asshole got used to him being inside me. The feeling of pain changed to one of sheer and utter delight as his cock continued to pound into my ass. Then as Michael leaned over me, his cock penetrating me deeper, my cock and balls let go filling Ann's pussy. I came and came like never before. My whole body shook with the orgasm I was having my balls just seemed to spurt cum time after time into her hot pussy.
I'd just about stopped cumming, when I felt Michael's cock swell and then felt his seed explode inside me. It was such an awsome feeling knowing I'd just been fucked my both of my future wife's parents, I almost cried with insurmountable joy.
Michael pulled out of my asshole and I pulled out of Ann's pussy, but it didn't stop there. No sooner than I'd moved away a little, than Michael dived between Ann's legs and began to lick out her pussy. Breaking off for a second or two Michael turned to me and said "Well either suck me clean boy, or let Ann suck you". Both things happened. Firstly Ann insisted I stand close to her face and feed her my cock. Then as my dick began to harden again, Michael had me sit next to Ann as she spread her legs to pay with herself. Then he stood up to me and put his cock head close to my mouth. I didn't need him to ask me, I opened my mouth and accepted his cum and anal juice covered cock over my tongue.
Michael's cock took longer than mine to become erect again. not as a result of my cock sucking skills (Of which I had none at the time) but because at forty eight it just took him longer.

No sooner than he was fully erect, he got me to lay on the rug in front of the fire, putting my lower back onto a large sofa cushion, and then got Ann to mount me reverse cowgirl. The reason he did that, was so she could watch him slide his cock up my asshole again. As they kissed, Ann fucked my cock and Michael fucked my asshole. I lay there thinking things couldn't get any more bizzare, when the phone rang. The answer machine picked up the message from my fiancee, who was talking and leaving a message as her parents were fucking me hard.

Ann climaxed for the first time, her pussy tightening on my cock as shuddered all over my dick. With them still kissing I felt Michale's cock twitching again and I knew he was going to cum. When he did cum, it was far more intense for him as he yelled out loud how good it was to empty his balls up my ass. Ann moved off me and then Michale moved away but told me to lay still. Ann moved back over to me, took my cock into her mouth and began to give me what I can only describe as a very strange but unbelievably good blow job. Strange because as she sucking my cock, she was also scooping out Michales cum from my ass, slipping between her lips and my cock then swallowing what let slide down my dick. A few minutes of Ann performing this sex act on me and I was cumming again, this time filling her mouth as she swallowed the lot.

When we sat and drank coffee ten minutes later, it was if nothing had happened. It was as if, all of us fucking one another was just a very natural thing to do. Before I walked out with my mind performing cart wheels, Michael turned to me and said "Your part of the family now, same time tomorrow evening then".

I did return the next evening, but Ann was working (Her once a month night shift). Michael and I spent over an hour learning about each others bodies and how best to give each other head. He also taught me how to fully accept his cock up my asshole and also how to fuck his. At his request I stayed over, but once we'd had our fun he asked me to sleep in the guest bedroom. He also asked, more insisted on it, that I never ever speak to my fiancee about what we got up to. The reason he asked me to stay was very evident the next morning as Ann woke me up for breakfast. She didn't wake me up the conventional way, no she she woke me up by sucking on my cock and giving a morning blow job. One I was only too pleased to cum in her mouth for.

Over the last year Ann's involvement has decreased, but mine and Michael's has flourished. We have sex, whether that be oral only, anal only or everything goes sex depending on time and place, probably once or twice a week. It's usually at their home when I pay them a visit. something a now legal son in law should do with his very understanding in laws Michael tells me. But now that we are married I think it's time for it all to stop. However Ann who occasionally still wants my cock, but mostly Michael still figure we should carry on fucking one another. It is tempting to let it slide and still fuck with them both, but I don't know how I'll feel if and when my wife tells me she's pregnant.
