Dad had decided to throw a birthday party for my twenty-first birthday. That made me nervous because since Mom left us Dad had become more gay.
Apparently both of my parents were bisexual when they met. Her pregnancy had been a surprise and they married. To me they were ordinary Mom and Dad until I was fourteen. By the time I was eighteen I had figured it out.
I went away to college and Mom immediately left with her best friend. Dad had expected it. When I came home for Christmas break it was just Dad and me.
I loved my Dad and was not too upset to learn he sucked cock. I had watched him do so with a friend the winter break after Mom left.
However every school break I came home he tried to cool his gay escapades while I was there but told him not to make changes in his life just because I was home. He kissed my lips and said, "I gladly put my life on hold for my son."
It was not the first time Dad had kissed my lips but it may have been the first time he did so on purpose. I smiled.
I was not gay and in fact I always had a girlfriend. They only lasted about three months but I got laid often during that time. Dad knew that and encouraged my behavior although he always cautioned me about using condoms each time.
I understood where he was coming from but also understood that if he had followed his own advice I would not exist.
I declined the birthday party offer which seemed to hurt his feelings.
"Who would you invite?" I asked him.
Every name he came up with had a built in danger signs from my old girlfriends to any of his friends. He understood and asked what I would like for my birthday.
"Las Vegas," I said.
He broke into a big grin and said "Deal. Who do you want to go with you?"
"Just you."
That seemed to surprise him. He was holding back tears when he said."OK."
Then I did something I had never done before, I kissed his lips and said, "I love you Dad."
His tears flowed and I hugged him to me.
I really did love my Dad. He had always stood by me even when I was embarrassed he did. He had always encouraged me to pursue my dream no matter what it was at the time. He always showed his pride in me.
I had seen how lucky I was when I compared him to my friend's fathers. Except for the fact that Dad sucked cock he was better than any other Dad.
After my spring semester ended we went to Vegas.
We shared a room at the Bellagio and would be there for six days.
On the first day we never left the hotel, hell we never left the buffet. Dad and I had fun there but over ate so we needed some pepto that night.
The following morning we went walking and entered every hotel and every tourist trap on the strip.
We returned to our room in the afternoon and took a nap. We were in our boxer shorts when we did. When I got up to take a leak I saw Dad look at my semi-exposed cock.
Same old Dad I thought. I decided to leave my cock out as I returned to bed. Before I went to sleep I could hear Dad masturbating. I smiled.
That evening we went to a Cirque show and had a great time. After the show I wanted to go to a dance club and Dad told me to go ahead. I did go without him but found myself bored to death so I went back to our room.
Dad had company. He had a cock in his mouth and had his eyes closed. The guy whose cock was being sucked had his eyes closed. Both were nude on on Dad's bed. Neither knew I was there. I retreated and stood behind a curtain and watched.
I saw both were as happy as they could be, there was no argument to refute that. Both seemed to love the other was there for them. Dad slid his cock out of his mouth and put a condom on it. He got on his hands and knees and the man slid behind him and inserted his cock in Dad's ass. They fucked. The man groaned and Dad's cock spewed. They were done, or so I thought.
They took each other into their arms and kissed with love. The kisses and caresses lasted at least twenty minutes. Then they got up and headed to the shower together. I took the opportunity and left the room.
I wandered around the casino for a while then went back up to my room. Dad was alone watching TV.
In answer to his question I told him the dance club was boring, there were no real people there. He answered my question by saying he had made a new friend.
I kissed his lips, went to the shower and masturbated. I went to my bed nude. Dad noticed.
"Where did you meet this new friend?" I asked.
"In the casino. I won four hundred dollars on a slot machine and he was on the machine next to me. He told me I had enough to hire a woman for the night. He became interested when I told him it would never be a woman I would be spending my money on.
I invited him to keep me company for a drink. I invited him to come up to our room. I was happy you did not come back early. So was he."
"Well your evening was a lot more interesting than mine. Good night Dad, I love you."
"Good night son. I am so proud of you I could kiss you."
"You can you know."
He apparently thought about it then stood and walked to me and softly kissed my lips then returned to his bed. He was nude.
I ran that evenings gay encounter in my mind and had to return to the bathroom to masturbate again. I worried about that briefly then fell asleep.
The next morning I woke up when I felt a hand caressing my chest.
"The breakfast buffet is open, we need to go pig out," Dad said.
I grunted then headed to the bathroom. I peed and noticed Dad was looking at me. I brushed my teeth then went out and got dressed. Dad did not begin to get dressed until I did.
We loved the breakfast buffet and staggered back to our room well after ten. We needed a nap. We stripped to our boxer shorts and got in our beds. We were asleep in seconds.
Dad was sitting on my bed when I woke up.
"We have a tour of Hoover Dam in thirty minutes. Get dressed," Dad said.
I got up and dressed but wondered if my cock had fallen out of my boxers on their own or if it had been pulled out. Dad had been staring at it when I woke up.
Our tour of Hoover Dan was mostly boring. What wasn't boring was watching Dad seduce a man my age. The man was a ranger and he had apparently told Dad of interesting places to go. He was on duty of course so Dad could not have him.
When we got back to our room I went to the shower first then Dad did. We both remained nude when we got out. We had a different Cirque show to attend that night but Dad said he had a place to explore after the show. I asked him to allow me to come along since I was not enjoying the dance clubs.
He thought about it then said OK.
After the show we took a cab to a place away from the strip. It was a gay club. Dad asked me if I wanted to try someplace else and I said no. I wanted him to have a good time too.
The place was interesting. The few women there weren't. Most of the patrons were Dad's age. Many saw me as a young stud. I was flattered.
Dad made his way around the room and I followed. Thirty minutes later he found what he was looking for. The man had grayish hair and looked like a movie star. Dad charmed him into his web. Dad was good.
Soon the three of us were in our hotel room. Dad and his guest became nude and began to kiss. I got nude and began to watch them.
Dad sucked his cock then did something I did not expect, he fucked the guy in the ass. Until then I had assumed Dad was a bottom. They were soon done with each other and the man left.
"Well, what did you think about all that?" Dad asked.
"I think you have more powers than I thought and you are more unpredictable than I thought. Thanks for letting me watch."
"Not a problem but when are you going to have fun?"
"I was having fun tonight. I like watching a master at work."
He laughed and came to me. He took my face in his hands and gave me a long loving kiss.
"You can masturbate on your bed if you need to," he said as he went to the bathroom. I was masturbating when he came out and kissed my lips before going to bed.
We spent most of the next day in our hotel's pool. Dad spotted a target and talked him into coming up to our room.
"Is your Dad gay?" the woman whose husband Dad had taken to his room asked.
"Yes. Your husband will enjoy the experience."
"Are you gay?"
"No. Do you need me me?"
"Yes."
She took me to their room and we fucked for quite a while. She told me her husband was bisexual and needed a cock every once in a while. They usually came to Vegas for that and he usually picked up a man with a wife and she had the wife. She was very happy to see he had left her with a fine young man that day.
I fucked her then made love to her then fucked her hard until I filled her pussy. She may have had seven orgasms. I left her dozing contentedly as I went to our room. The man was fucking Dad when I walked in. I went straight to the showers and got in bed when I got out. The man was being fucked by Dad. I watched for a while but fell asleep before they were done with each other.
