A few years ago when I was much younger I was married to a 40 old Beautiful Blond women who looked 30. She had nice tits and a great body. She and I when having sex would talk about bringing a guy into bed with us. She would get all wet and I would get a big boner. A couple weeks ago her Marine bother had to go on a mission for a couple months. He has custody of a 15 year old son and ask if we could take him in for that time. Of course she said yes. She pick him up at the bus station and brought him to our home. Wow, he's about 6 ft and around 165 pounds. He's a good looking blond kid. I took him out in the fishing boat the very next day. In our our talk he admitted that he was still a virgin. He very sly but did confess to jacking off two or three times a day, he said that with a real red face. He stood up to take a piss and his cock looked to around 9" soft. Now I've never BJ a guy before, I got a instant hard on. Later I told my wife Fran what I saw and she got very excited. We noticed when we were sitting on the couch and her nephew Joe sitting across from her, he was always trying to see up her dress without being caught. I came up with a plan to see how how far we can go. I ask Fran to put on a short dress and no panties and she was very game. As we were sitting on the couch she position herself so Joe could see her blond hair pussy. Joe pick up a magazine on the table and lay it on his lap to cover his big boner. We let him have a couple of beers as we had something a little stronger. We begin having a very sexy Conversation and he would turn a little red in face. After a bit he started to join in. Fran spread her legs more making it obvious it was intentionally. Fran ask Joe to remove the magazine off of his lap and show her his bulge. Joe is very sly but he did as he was told. Wow she said. She open her legs all the way and ask him to come over and he did. She unzipped his fly and took out his cock that looked be 10". She stroked it just a couple of times and he drop a load that could fill a coffee cup. She scooped up with her hand and put some in her mouth. She lean over and kissed me and make me stick my tongue in her mouth. Wow, I've never even tasted own cum. My cock got very hard in a flash. He had a uncut cock with big shiny purple head. She pull the foreskin over her tongue covering about 2" of it. Bang, one more big load of cum. Ok Joe she said fuck me now and hard. He push that big cock into her and she let out a squeal. He was riding her hard and she was moaning louder than I have ever heard her. I now had out my 6" cock out and it was harder that when I was a kid. After he drop one more load of cum, he pull out his cum cover cock. Ok My wife said clean me up now and I did. Ok now clean the cum off of his cock and I thought now or never. As I was licking the cum off his cock he unbelievable got hard again. He grabbed my head a started face fuck my face. I was gagging but didn't stop sucking. There one more load of cum and swallow it all and love it. I guess there is no doubt now I'm Bi and don't care. His is not going be be the last cock I will be sucking. We have make a Monster because he said anytime he want to fuck his aunt or ram his cock in my mouth he will. He said if not he could tell his mean dad and we would be in big trouble. For two months he fucked my wife and face fucked me two or 3 times each day.we are going to miss this boy when he gone.
