When Catherine arrived, I met her at the door and gave her a huge hug. Callie came bouncing down the stairs and joined us in a group hug. After we were finished, I carried Catherine's bags up to her bedroom and helped her unpack.
"So have you two been good?" Catherine asked.
"No, Mom, I'm afraid that we've been very bad" was Callie's response.
"Excellent!" said Catherine. "I was hoping you'd say that."
"Mom, I wanted to say thanks for allowing me to fuck Bob this weekend. He's been the subject of many wet dreams for the last several weeks. I'd wake up hot and horny, and have to stick a finger into my pussy to ease my horniness."
"Callie" I began "I've been having similar dreams myself. Mostly they've been of your mother and me, but some have been of you and me. I couldn't figure out what was going on, especially since I've not had a wet dream since I was a teenager myself." We all laughed at the similarities in our dreams when Catherine piped in.
"I've had the same type of dreams, and I've needed to masturbate most mornings when I wake up. I thought it was just me." We laughed again before talking about our relationship.
"Bob, Callie and I have done a lot of talking before this weekend. I think you've figured that out for yourself already. One thing that we discussed was what the future holds for us. I say 'us' since anything that you and I decide will directly affect Callie as well."
It felt like a bombshell was about to drop here. "So what did you decide?"
Callie jumped in. "We know that the sex has been great between you and Mom, but it has been more than just sex. You two have created a bond that can last for a long time."
"And now I find out that the sex between you and Callie was also great. Obviously, the relationship between you and her has changed, so we need to address that." Catherine took a deep breath, then got to the point. "Callie and I agree that you need to move into our house. We'll both act as your wife in almost every way. We've all agreed that the sex is wonderful--let's take that to the next level."
"But Callie" I said, playing devil's advocate, "don't you think you'd be happier with a college aged boy instead of someone old enough to be your father?"
"Age is not as important as the feelings between us. I'm attracted to you on many levels, and I know you and Mom love each other. If we can share all of that, why not?"
Callie smiled sweetly at me while I pondered this. I kept trying to find reasons to say no, but as long as we aren't hiding anything from each other, what harm could there be?
"Bob, we have a bigger house than we need, and we could convert one of the bedrooms to an office. There's plenty of storage here. Just say yes."
"OK, I agree. I'll put my house on the market tomorrow. My friend, a real estate agent, says that my house will probably sell in less than a week."
Again, they found each other in a group hug. Callie was the aggressor this time, reaching down to my cock and rubbing it through my pants. I moaned my approval as I reached out for Catherine's boobs. I rubbed them through her shirt, and could immediately feel her nipples come to attention. As I tweaked them, she and I engaged in a long French kiss. After several seconds, Catherine backed off and removed her t-shirt, exposing her B-cup boobs, then removed my own shirt. We rubbed each other's nipples as Callie reached inside my pants and pulled my stiff 7" cock free of its confines.
Callie paused for a moment to remove her own shirt, showing us her A-cup tits, then unsnapped my pants and slipped them down my legs. She then began licking the length of my cock, slurping as though she had a lollipop. I moved one hand between Catherine's legs, stroking her pussy through her pants. In just a few moments, she unbuttoned her pants and opened her zipper. I slid her pants over her ass and let them fall to the floor. I then put one hand to her shaven pussy lips, and slid a finger into her crevice.
Catherine moaned as my finger quickly slid between her lips and inside her cunt.
