Me, My girl and my mate

My mate came over for a piss up one weekend, and he, my missus and I proceeded to get nicely drunk. We had all been friends since highschool and he and my girl had a sort of thing in their early teens, so therewas always plenty of harmless flirting going on. This particular weekend was after a rough patch for him and his missus and a very busy week for me at work. Needless to say, he needed to talk and I was knackered. I found myself closing my eyes while listening and excused myself to go to bed.I passed out, they kept talking.
I woke up about six o'clock to the sounds of soft moaning coming from our loungeroom. I silently crept out of bed to see what was up, and the sight I saw shocked me to a standstill! Because there on our couch was my mate being ridden in the cowgirl position by my girl, he had his head buried in her ample 12D cleavage and his hands firmly clamped on her ass cheeks. She was the one moaning. And not from the size of his cock which appeared to be about 6-7 inches, and, thinner than mine. But because his cock was in her ass! Now I've always loved anal sex but my girl had said I was too long and wide for her to keep at it comfortably for any length of time.
As I stood watching, I got hard, REALLY hard. I couldn't stop myself from sliding my cock out of my boxers and glently stroking it to the rythym of my girl on his cock. This continued for a few minutes before he suggested she do the same in reverse cowgirl,Iquickly ducked back out of the room and peered around the corner to see my girl assisting him to guide his cock into her ass, then she put her feet up beside his legs on the couch so she could once again control the pace, which she did with louder moans and a grunt from him. I began to get angry when she quickened the pace, with his help, and loud slapping noises started filling the house. I forgot my hard on and the fact I was still stroking it, albeit faster now and with more force, and stepped into the room fully as she lifted her head to orgasm.
She saw me standing there and stared straight at my cock, she told me to come closer, my anger was replaced with confusion. In a stupor I obeyed. She began to give me the blowjob of my life while my mate continued the anal screw of her life, unpeterbed by my prensence. My confusion and anger released and I became overwhelmed by the eroting feeling of having my girl suck me like a possessed woman and I blew my load in her mouth. She swallowed, grinned, and told me to kneel and return the favour.
I was so turned on I would have done anything asked so I readily obeyed, but was again shocked at her taste. I could taste sweaty cock in her pussy as I slid my tongue in deep inside her, my mates balls occaisionally slapping my chin.Again I was overcome by eroticism and began eating her out with renewed enthusiasm. I also slipped a finger up her followed by two, while I sucked her clit for a moment.Then I got my second surprise of the moment. As I withdrew my fingers they were covered in what was clearly not her cum, but was buried deep inside her! She had let him cum inside her, and had made me go down on her after it! I proceeded to suck it off my fingers while she watched and she came with such force that she squirted a little of her own juice out as I returned to my job of sucking my mates cum out of her swollen pussy.
When she finished her orgasm, which all in all went for close to a minute, she told me to put my cock in her pussy and replace my mates cum with hers, I willingly obliged................
