Sue said "Not a sole Dan, we're safe", and smiling she turned back to the door.
Dan then turned, letting his towel fall off, grabbed Billy's cock and licked the pre-cum from the tip. Suzy ran her index finger though her fertile cleft, stood up and walking toward me, she offered me the very wet digit. She had perfect little cones for tits with large very hard nipples. I sucked on her finger enjoying her sweet juices. She grabbed my hard cock and pulled me to my feet. Then she guided me over to Dan. Dan was now going down on his son while playing with his own now hard cock.
Suzy pulled me down in front of Dan and said "If you suck daddy and Billy real good maybe you and I can play."
Dan guided my head down onto his son's thin six inch cock. He was very tasty with cream just flowing out. Meanwhile Dan started stroking my cock then lowered himself to the floor to take me in to the base and swallowed a few times. How intense that was, as no one had ever done that to me. I thought I was going to bust a nut way too soon.
Sue stepped forward and spread her legs showing me her perfectly shaved snatch. She pulled my face off her son and kissed me driving her tongue as deep in my mouth as her husband had taken my cock. When she finally stopped she said "Kids get wrapped up and presentable we're going back to the suite! All of us are, Grandpa, so we can relax and have even more fun than possible here." As they left Sue told me "Give us ten minutes, then come up to our master suite which was right above the sauna."
My head was spinning from the heat in the room, both sexual and the steam. I left the sauna and climbed into the shower for a cold shower to calm me down.
Ten minute later I was standing outside their suite too nervous to even knock. I didn't have to..... Sue opened the door and was standing there now totally naked. Her tits were much bigger than her daughter's but still were perfect cones with just the slightest sag. And her nipples..... they were as big as my little finger tip. I could even see her clit was just as big, Almost like a little boy's penis. I must have been staring because she had to ask "Do you if like it? "Would you like to get your tongue on it, maybe while my son is fucking me over your face?" "Dan and Suzy are working on an treat for you to eat later." She then drug me inside and shut the door.
Next thing I knew my shorts were being pulled down by Billy and he started sucking my cock while his mother stripped my shirt off and shoved her tongue back down my throat. She walked us back to the plush couch and pushed me down while crawling up my body. I latched onto one of those big nipples and lightly chewed before trying to mash her entire breast into my mouth. It would never have fit anyway but sure was fun trying, she proceeded crawling up my body until her thighs were trapping my head. She was dripping wet even before I wrapped my lips around that beautiful love nub. As I feasted on her juicy snatch I felt Billy crawl up behind his mother. I saw his small dick approaching and grabbed it in my lips. I rubbed his cock against his mother's clit and licked them both. Actually able to suck both into my mouth at the same time.
