I guess the true test of an open marriage is when your wife wakes you at 1 am wearing only an unbuttoned shirt, with a 21 year old in tow and asks " Is it OK if I fuck him?". We have had many adventures and shared our bed in the past with both men & women, but this was an all time high water mark for sexual acts. And I watched (and helped) as this young stud proceeded to fuck the daylights out of my wife right in our bed. The evening started out innocently enough. My gorgeous wife does some light bookkeeping for local businesses and this night she had to run some papers to a nearby town. The papers were for a bar that a friend of ours is partner in. The idea was to run over, drop off the papers, maybe have one drink, and then home to me. Now Liz, my wife, attracts men like a bug zapper. Only she likes to unzip rather than zap them. She's a very curvy 5'7", with blondish hair, what I consider not only bedroom but "fuck me " eyes, long legs and a super attitude. Like I said, we've had some adventures before so I knew something was up when she called after a couple of hours and asked if it was bad to fool around with a 21 year old (she's 35). I said no as long as I either heard about it or got to help. Liz said she'd call later. She called one other time and told me this guy was a good kisser and was I sure I was OK. I said I was fine, just to be careful driving home, and that I was going to bed as I had to work the next day. She said she'd be home soon. That was at 10:45. I awoke to the sound of the back door being opened and some one stumbling down the hall. The clock said it was 1:05 am. I was relieved Liz was home safe and raised my head to look at the door as she came in. Liz walked slowly into our bedroom wearing only her sleeveless shirt, unbuttoned all the way. I could see by the nightlight that her long nipples were hard and her shaved pussy looked wet. I then saw the guy she was dragging behind her. He looked young and terrified. He was tall and blonde, fully dressed and seemed hesitant. "I thought you were shittin me when you said you had a husband", he said. Liz said " Honey this is Bill and he likes it when I pee in his mouth." Well what do you say to that ? I said "Hi". Liz asked if this was OK and I assured her it was. Liz shrugged her shirt off and laid on the king size bed. She beconned Bill to join her which he did. She told him to take his clothes off first, so Bill got up and undressed. As soon as his cock was free, Liz was stroking it. I had no doubt that they had already been fucking or something, owing to Liz's attire and the lateness of the hour. I pulled my shorts off and watched from the other side of the bed. Liz spread her long legs and told Bill to eat her. Bill dove between her legs and she groaned her approval of the location of his tongue. I sat up and Liz grabbed my hardened cock and pulled it to her mouth. Liz is a very vocal lover and tonight was no exception. She would pull my cock out to moan and encourage her young lover, then suck me back into her mouth. This went on for a while with Liz coming many times. Bill laid down next to her and she dove onto his cock, slurping it into her mouth. Liz loves to give head and she is very good at it. Bill groaned"Suck me baby", as Liz took his cock to the root. Since I wasn't doing anything I laid down behind Liz and started licking her pussy and ass. I expected to taste come there bur Liz was so wet, I couldn't tell. I did however notice that her asshole seemed relaxed and loose. I reamed Liz while she sucked Bill. Liz dearly loves to have her ass eaten and she was pushing back against my face as she came. After a bit Bill asked if he could have a drink. I got up to fetch some sodas while they kissed and cuddled. They drank a few sips and then went into a clinch. Liz laid back and simply said "Fuck me". Bill obliged and rammed his cock into her. Liz started coming almost from the first stroke. She stuck her legs up in the air and pressed her crotch against the invading prick in her cunt. Liz moaned loudly and told Bill to fuck her more. I moved up towards the head of the bed so Liz could see me stroking my own hard cock. Liz really likes to watch me jerk off while she's being fucked. Liz reached out and grabbed my hand in a death grip as she orgasmed from the pounding her cunt was receiving. She kept her legs up in the air almost the whole time, moaning and fucking back. Bill placed her feet on his shoulders to vary the pace some. He then almost bent Liz double while he raised up on his toes to stroke his cock to the hilt and then back out. I could actually see the head of his cock as he pulled back before ramming back in with a slapping sound. Liz was ecstatic and taking every stroke by lifting her pelvis off the bed. After a while they took a break and had some more soda. Liz reintroduced us thinking she may have forgotten to in her haste to get fucked. Bill stayed hard and re-entered Liz, this time sideways on the bed. Liz's head was almost hanging off the edge. Bill fucked her steadily and again she gripped my hand as I stood by the side of the bed. At on point I slipped my cock into her mouth and she sucked me as she got fucked. Her moans and grunts soon made it hard to keep me in her mouth. Bill picked up the pace and Liz began begging him to come in her. "Fill me up", she said. "I want to feel your come shoot into me". Bill fucked for a few more minutes and then stiffened as he shot his load into Liz's pussy. Liz was completely wrapped around Bill as she received his sperm. Bill slowly pulled out and lay back as Liz rolled over and took his cock in her mouth. Liz was not done yet. I got on the bed behind Liz and began to eat her sloppy pussy. Liz comes really hard when I eat her lovers come out of her pussy (or ass) and this was no exception. She had to pull Bill's cock out of her mouth while she panted through yet another orgasm. Liz then rolled onto her back and spread those lovely legs for me. As Bill watched, I placed the head of my cock at the entrance to her recently fucked cunt and pressed forward. Liz was very wet and loose inside. I went all the way in. I fucked her steady but gently. I didn't take long before I was ready to add my load to the one already deposited there. I asked Liz " Are you ready for my come?". She said yes, to shoot it in her cunt. I came and filled her up with the amount of ejaculate. We lay still for a few moments, enjoying our union. I pulled out and Liz rolled back toward Bill and began kissing him. But the booze they'd drank and the late hour prevented any more fucking. Liz curled up in her new lovers arms and fell asleep. Liz told me the next day that they had left the bar right after she called last, but stopped on the way home at the soccer field and played around. She didn't remember all of it but said she did remember getting on her hands and knees and telling Bill to fuck her in the ass. That explained the loose ass I found and the lateness of their arrival. I never did find out how she knew he liked her to pee in his mouth. Oh well, maybe next time things won't be so foggy.
