Jason could do little else but stand there and gawk at the situation. Everyone was naked and staring at him and Jean who had her hand wrapped around his stiffening member. Jean played with it and stroked it lovingly. This action only made it harder and longer. Jason wanted to run embarrassed back to the bedroom from whence he came, but was transfixed into this unbelievable scene before him. His brothers gawking at his hard cock which seemed like a monster compared to theirs, his sisters, one with her hand on his member the other licking her lips remembering what she had just put in her mouth.
Jean leaned forward and kissed Jason on the lips, not that sisterly kiss, but one of a wanton lover hoping for more than just a little pet and caress game. Jason closed his eyes and kissed her back knowing that it was not his mind that was in control, but his body. He felt other hands now roaming over his body, caressing him everywhere, gently feeling him on every inch of his body. He felt Jeans tits brush over his chest as she strained on her tip toes to kiss him and Jason responded by pulling her close and bending down a bit to facilitate the woman trying so hard to bury her tongue deep in his mouth.
Jean moved her legs apart just a bit to allow Jason's monster cock slip between her legs. It was big enough so that the end stuck out between her cheeks like some snake trying to escape the bonds of flesh that held it. He then felt someone's mouth on the tip and they were sucking it hard trying to pull the rest of it away from his body. Jason erupted and heard the mouth that had hold of him cough a bit and back away. The lips that left him were quickly replaced by another set and without spilling a drop of cum, swallowed the rest of his ejaculation. Jason opened his eyes and realized that the lips that had relieved him of his copious amounts of cum were his brothers as Jen was behind him stoking his ass and Jean was still entrenched in his mouth.
Jean felt his cock deflate and she opened her legs and let it fall to his front. She backed away from Jason and led him to the couch. The guys came over but Jen said, "You guys had yours, now it's our turn." Jim and Joe reluctantly went across the room and sat down, playing with each other. Jean bent down and started to suck on Jason trying to revive him while Jen straddled his face. Jason looked at that beautiful pussy and immediately started to suck on it. Between Jen and Jean he felt the stirrings of another erection and tried to push his cock deeper into Jeans mouth. She gagged and coughed but tried to swallow as much as she could. Jason thought that Jen was much better than her sister, but still he enjoyed the feeling of Jean's soft mouth on his dick.
With his erection in full attention again, Jean got up, straddled him, and started to push her pussy down onto Jason's cock. What a feeling she thought, for years she had helped herself to Jim and Joe's cocks fully enjoying what they had, and even her ex was a wonderful lover, but never had she experienced being this full. She sank ever lower until she had all she could handle inside her and then it hit. Her forth orgasm of the evening, this one more intense than the others. She started to buck on this monster and grabbed her sisters tits for balance. Jen was enjoying the feeling of her pussy being eaten quite expertly by Jason and Jean grabbing at her breasts when she exploded and Jason swallowed all the juices he could with most of them dribbling down his cheeks. Jen slid off his face and Jean leaned over to lick his face and ride his cock some more. Jen leaned over her sister and started to lick her ass and slide her tongue down that valley to taste the mingling of Jean and Jason. When she started to suck on Jason's balls, he erupted into Jeans pussy which caused her to orgasm again. The combined flow of their lovemaking drained out of Jean's pussy and over Jason's balls which Jen greedily sucked down and tried to keep up with but couldn't.
Jean slid off of Jason and Jen obligingly sucked on Jason's cock. Again he felt the entire length go into her mouth and reveled on the feeling. No one had ever engulfed his entire member until now and here she was doing it again. Jen loved to suck cock, especially big ones like this. She loved the feeling of it deep in her mouth and throat really enjoyed the feeling of the throbbing as it pumped the man juice down into her belly. This tasted especially good as it was covered with Jean's pussy and Jen was in heaven. When she worked her way to the bottom, she stuck out her tongue and licked Jason's balls, this caused his cock to twitch back to life and start to enlarge again.
Everyone looked on as Jen gave them a lesson in deep-throating a monster and Jim and Joe envied her for her talent. They had often gone down on each other but sometimes gagged on their own penises and wondered how this vixen could swallow Jason's cock so easily. Jen lifted her head to reveal the throbbing hard on of her brother and looked around the room. Jim, Joe and Jean soon were at her side each in turn trying to mimic the talent they had witnessed, but not even coming close to equaling it. Jason lay there and was awed by the fact that everyone in the room was trying to swallow him whole.
Jen finally pushed everyone away and slid her ass over his stiff member. She slowly pushed until it popped inside her butt and then she slowly slid down till it was completely inside her ass. Jen arched her back and leaned on her brother. Jason slid his hands around her and held on to her tiny tits feeling the nipples and squeezing them between his fingers. Joe got on his knees and started to eat Jen while licking Jason's balls. Jean crawled between Joe's legs and started to suck him off while Jim got between his sister and started to fuck her. Each connected to other hoping to get Jason inside themselves. Jason looked down at the chain of incest in front of him and shot his load inside his sisters ass. Jen in turn exploded into Joe's mouth who let loose into Jean which caused her to orgasm squeezing Jim's cock in her pussy and the chain reaction of his ejaculation into Jean.
Jason's cock slid out of Jen's ass and Joe dutifully sucked it clean as she slid off his lap. They all went to the available seats in the living room and took a sip of the drinks they had neglected for the past couple of hours. Jason looked at everyone and asked, "How long have you guys been doing this?"
"Quite awhile," answered Jean. "I guess it all started when I caught your brothers experimenting. I walked up on them beating each other off, they didn't see me so I watched for a bit. At first I was kind of shocked, but then I got so turned on so I watched to see what was going to happen next. I was surprised to see Jim and Joe go down on each other and when they did that I had an orgasm. Guess I made some noise cause they heard me and instead of covering up and stopping, they pulled me in and started to undress me. Next thing I know we were fucking like minks."
"When I got home from college they were already into fucking a lot" said Jen. "I was already bi when I came home and was out looking one night and struck out from both sexes. When I came home, they were in the boys bedroom going at it like nobody's business. I just stripped off my clothes in the hall and walked in. It was like I belonged and I jumped right in." Everyone chuckled at her.
"Joe and I have always like to suck cock, guess we got started that last year at summer camp. We had all just turned 18 and bored with the stuff they had for us to do, one of the other guys said he had something that was more fun, so we tried it. It was a circle jerk for money, everyone put a dollar in the pot and first one who came got the pot. I won! When we got home Joe and I just took it to the next step. That's when Jean found out about us."
"Have you ever though about sucking a guy off Jason?" asked Jen.
"No, but I have had a couple of blowjobs by guys that saw my cock and wanted to suck on it. Hey I don't care who wants to suck me off, but I got to say, Jen gives the best head I've ever had. Any time you want to suck me off baby, just go for it," at which Jen blushed.
Jim and Joe walked over to Jason and got on either side of his knees and started to suck on his cock each taking turns getting the entire thing in their mouths while it was still soft. Their ministrations cause it to swell a bit and they knew that soon they would only be able to suck on part of it. Jen came between them and said, "This is how you do it boys," and they dutifully moved aside to watch the master or mistress as the case may be. She easily swallowed the cock in front of her and bobbed her head on it slowly to feel the entire length with her tongue. This time she would not be denied the cum she longed for in her mouth. Jean moved next to Jason and kissed him deeply. He knew from this time on that he would never be an outsider to his family again. He knew he belonged.
