Monday morning I sat in my office in a daze. The weekend with the girls had been fabulous, we had great sex Saturday night and more sex twice on Sunday.
Sunday morning Erica had asked that Kim and I give her a 'DP' experience and we did our best. Erica, on her knees in the middle of the bed, let me fuck her face while her bi-sexual lover, and my step-sister, Kim, used the large dildo attachment on the strap-on and fucked Erica from behind. By prior arrangement, Erica wanted me to unload my cum in her mouth, but she didn't swallow. What I didn't know, until it happened, was that Erica and Kim had planned a cum-swap in advance. When Erica had her orgasm, it triggered my orgasm, which filled her mouth with my cum. Kim had pulled the strap-on out of Erica's pussy and got into position for the two girls to kiss and swap my cum back and forth, snowballing it.
It was so erotic that my cock stayed hard. Soon I was fucking Kim and giving her an orgasm.
That night was one of our designated 3-some nights. According to our new arrangement, we would have 3-some sex on Sunday, Tuesday, Thursday, and Saturday. Monday night would be just me and Kim, although this week Kim had forfeited her night to Erica. Wednesday night would be just Erica and Kim, my night alone in the guest room. And Friday night would be me alone with Erica.
During our 3-some nights we sometimes did round-robin 2-somes. I would have sex with one girl. Then while I recovered, the two girls had sex, followed by me having sex with the other girl. Of course, the odd person out often was involved by kissing the others, or lending a hand for manual stimulation to the other two. So, in essence, we were all involved in all couplings.
Other times, we looked for different ways to have true 3-some sex, something where we all were sexually involved and could attempt to all have an orgasm together.
Last night was one of the latter type of 3-somes and we used one of my favorite ways. I laid on my back with one girl riding my cock while the other rode my face. The two girls were facing each other so that they could kiss and play with each other's tits. Together we had a fun, messy time and we all had our orgasms together.
As I sat at my desk Monday morning, reminiscing about the weekend, Joe walked past my office and saw the silly grin on my face as I stared into space. He walked in and closed the door behind him.
"I want whatever you had this weekend."
Joe spoke, knowing generally about my arrangements with Kim and Erica.
I looked at Joe with a big grin.
"Actually Joe, I am glad you dropped in. I have a question for you."
"Fire away, but I think the answer is 'Yes'."
he replied with a sly smile. It was almost as if he knew where this was going.
"I want to know if you would like to join Kim, Erica, and me for dinner tomorrow night at The Top Hat restaurant?"
I asked him, attempting to keep a straight face.
"Are you kidding me? Of course I do. Is this just for dinner, or do I need to bring my toothbrush and a change of clothes?"
Joe was very eager in his response.
"Slow down there stud."
I replied trying to manage expectations.
"The girls don't know you and want to just meet you on safe turf. Nothing else will happen tomorrow night."
I thought that Joe was going to kiss me or maybe just hug me. His excitement was clearly obvious. I kept my distance and when he extended a hand to shake mine, I shook his hand.
"Tomorrow night is a date."
he stated as he left my office, a bounce in his step.
After he left I sent a text message to Kim and Erica.
"Dinner with Joe tomorrow night"

When I arrived home Monday evening, the girls were waiting for me, eager to discuss our planned date with Joe on Tuesday. I was somewhat surprised that they apparently wanted to have a stranger join us in our home, and possibly in our bed. One might have thought that I was bringing home a present or a new toy for them. And maybe Joe will be a new boy-toy for them.
"How did it go with Joe? How much did you tell him?"
asked Erica.
"Does he expect to join us in bed?"
added Kim.
"Joe is eager to meet you."
I replied.
"He knows that there are two of you, and only one of me, so I think he has certain, . . . hopes. I tried to control his expectations for tomorrow and I told him there we'll only be having dinner, nothing else."
The girls had prepared dinner, so after changing into comfortable clothes and having a beer, I joined them at the dinner table. They continued to ask questions about Joe, and for the most part I told them they would have to meet Joe and hopefully their questions would be answered.
After dinner we all moved to the couch in the TV area. They continued to ask questions and discuss how we might add another to our bedroom activities. I was hesitant to be discussing having Joe in our bed as the girls had never met him. But they persisted in that line of conversation. The more we talked about our 3-way sex and some possible 4-way sex, the more each of us was becoming aroused. Soon we were kissing, touching and eventually removing clothes.
We moved to the bedroom and engaged in various 2-somes and 3-somes while even continuing the discussion about adding possibly Joe to our play. It was all a bit surreal to me. There never was any question that this was supposed to be my one-on-one night with Erica, and we all enjoyed our evening together and all three of us fell fast asleep together.
+++++
Tuesday at work I began to have second thoughts about the course we were pursuing. Did I really want another man, and a long-time friend at that, naked in bed with me and the girls? I knew that Joe and I would not be doing anything with each other, but just the thought of two men having sex with two women together in the same bed at the same time began to concern me. Was I really ready for this? Is this really what the girls wanted? And if this happened, would it be a one-time thing, or would it repeat? For some reason I could only think about how things could go wrong, and there were plenty of ways. I tried to focus on the fact that tonight was just dinner. There were no definite plans for anything beyond dinner.
After work I drove home to shower and change clothes before going out for dinner. The Top Hat was a fancy place and we would all dress up. Kim and Erica looked stunning in their dresses and heels. They had spent time on their hair and make-up. Their appearance brought back memories of the night the two goddesses and myself first used our new bed, although that night they were naked and tonight they were fully clothed. Either way, they looked stunning. I wore my best suit.
Joe was waiting for us at the restaurant. He wore a big smile as we approached. Erica and Kim each gave Joe a greeting hug. Everyone appeared to be comfortable. There were no obvious signs of nervousness by anyone.
The restaurant had taken our reservation and had a table waiting for us. We were promptly seated and Joe began the conversation.
"Charlie has told me a lot about you two. I am so glad to meet you in person. You both are stunningly beautiful."
Joe was lobbying hard to be in good with the girls.
"I hope he hasn't told you EVERY thing."
replied Kim is a suggestive voice.
I was a bit concerned that the conversation was moving too quickly to a discussion about our sexual activities, but for now I stayed out of the conversation.
"Is there more I should know?"
