Brian was having his morning coffee before it was time to leave for work and his mind was a jumble of the events of the previous day. He just couldn't grasp how Laura, his wife of 22 years, could allow, no, encourage her sister in law to suck his dick. After all, Beverly is his own sister. And what about his own children, Bobbie and Katy. She has known they were having sex for months and kept it secret from him. Katy is almost 22 and Bobbie is 18 so he guessed they were old enough to make their own decisions but he just couldn't believe Laura has watched them fuck and never said a word. He couldn't even understand his own actions. His cock had stayed hard as stone after Bev had swallowed his load and he and Laura had a fantastic session on the floor of the living room while Bobbie fucked his aunt on the sofa beside them for a second time. Later at bed time he fucked Laura again. Brian couldn't remember the last time he got off 3 times in so little time.
Brian looked up as Laura entered the room and poured herself a cup of coffee. She walked over and freshened his cup and he couldn't help but notice her robe was untied with nothing under it. Even after 22 years the glimpse of a nipple could cause a stir in his loins.
Laura smiled and said, "A penny for your thoughts."
"I don't even know where to begin", he replied.
"Well, let's start with the obvious. It's clear that Bev and you both enjoyed that bit of oral sex so sibling sex must not be too objectionable to you".
Brian took a sip of coffee and looked at Laura. "Bev is a great cock sucker and I'd be lying if I said I didn't like it."
"Which brings us to Bobbie and Katy. I'm sorry I never said anything but I just didn't know how you'd take it. I didn't want to do anything to spoil their fun. They are so beautiful together and there is no doubt that Katy and Bobbie love to fuck. I've never seen anything wrong with a little family fun."
Brian looked up from his coffee. "So you approve of incest?"
Laura took a deep breath and said, "Yes honey I do. I think it's a lot more common among siblings than most people think. I've never told you about how my brothers, Larry and Lonnie, used to fuck me when we were younger and Sandy, Larry's wife, fucked her own brother even after she and Larry were married. I wouldn't be surprised if their four sons keep both of their sister's pussies pretty busy too."
"Wow, I had no idea any of that was happening."
Laura glanced down at Brian's lap and giggled, "By the looks of that lump in your pants I suppose you aren't exactly opposed to the idea. Maybe I should fix that before you leave."
Laura kneeled down in front of her husband and unbuckled his belt. Brian raised up in his chair so that Laura could slip his pants down past his knees. She took his cock in her hand and ran her tongue up and down the underside and then licked his heavy balls. Her robe hung open and her hard nipples pressed against his thigh. She sucked the fat head in the mouth and slid her lips over his dick. Laura loved to deep throat a cock and she was good at it. Brian knew he wouldn't last long this morning.
"Well, aren't you two frisky this morning?" Both Laura and Brian looked up at Bobbie as he entered the kitchen. Bobbie just smiled and said, "Don't let me interrupt you."
Bobbie's mother stopped sucking the cock in her hand and said, "I'll fix your breakfast as soon as I finish here."
"No need, mom, I'll just pick something up later because I'm already late for practice." With that Bobbie rushed out the door.
Laura resumed the blow job and Brian began to thrust his hips, trying to fuck her mouth the was he knew she liked. He soon erupted and Laura sucked his cum down her throat and licked her lips.
"Sorry, but I've got to get going so I'm not late for work", Brian said as he pulled his pants back up and took a last swig of coffee.
"No problem", Laura said as she kissed his cheek, leaving a small smear of cum.
Brian hurried out the door and Laura decided she should drop by and see how Beverly is feeling after the exciting afternoon they all had yesterday. Little did she know just how exciting it had been for Beverly.
****************************
Katy woke up and stretched. She had been out late on a date with a guy she'd been seeing for a while. He had driven her out by the lake and she allowed him to entice her into the back seat of his car. She had been looking forward to a hot time because of the promising bulge in his trousers. The reality of it was that even though he had a nice package he was finished after about six thrusts. She had came home hotter than a fox in a forest fire and was disappointed to find Bobbie in a deep sleep. In fact he was so sound asleep she couldn't even wake him. She thought back to their first encounter many months ago. She had been on a date and had an experience similar to last night. She was in her bed reading a magazine when Bobbie came home from a date which was equally disappointing. After he showered and dressed for bed he had came in to visit with his older sis. They had always gotten along well and Katy was always there for Bobbie. She was propped up by three pillows and Bobbie flopped on the bed in the opposite direction laying on his side.
"Hi sis, it's early so I guess your date didn't go much better than mine."
