Introduction: I'm a 66 year old man enjoying the sauna on a cruise ship. the family consists of four. Dan, the dad is 45. His wife is Sue aged 44. Their son Billy is 19 and daughter Suzy is 18.
A man and boy came to the cruise ship sauna door with towels wrapped around their waists and looked in. They came in, and the son set on the upper bench with dad sitting below him. The father looked at me and smiled, spreading his legs open and letting the towel fall between them. He son did too, only his towel fell far enough open I could see his cock and balls.
I don't know how long I was staring but when I looked back at the dad his towel was open too and he was smiling at me. We were all startled by the door opening. A woman and girl came in also in towels. She kissed the man and sat beside him. The girl crawled up on the upper bench beside her brother.
She then said "Mom! Billy's junk is showing."
Dad replied "So is mine, this man doesn't seem to mind. In fact his cock says he even likes it."
Mom smiled and said "I guess we can all get more comfortable then. I'll stand by the door so we aren't interrupted."
The daughter giggled and pulled her towel off, spreading her legs so I could see her bald mound with big lips, already glistening in the low light. She then reached over and opening Billy's towel fully showing all of his now hard cock. She stoked it a couple of times and said "Daddy, he's already dripping."
Dad said "Suzy, what do you expect, with this audience he's worked up already. Same as you, you're dripping too." "Sue, is there any movement out there?"
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."
