Life moved forward for us as we settled into a new weekly routine. Sunday through Friday, it was just Kim, Erica and me in our home, and in our bed. We continued our 3-some sexual activities three or four nights a week. And we continued the 1-on-1 couplings other nights which actually brought us even closer together as lovers.
Joe was often a Saturday night addition to our sexual escapades. It was becoming clear that neither Kim nor Erica were falling in love with Joe. They just liked him as a second boy-toy for their sexual play. The Saturday Night Fucks, as we started to call them, often lasted well past midnight, and resumed early Sunday morning. For Erica, Kim and me, the rest of Sunday became a day of rest and our Sunday night activities became more gentle, more loving and less physical, which was fine with me.

One recent Saturday Joe joined us for Pizza, Beer, & Porn. We were enjoying the food, the drink, and each other's company. The videos of 4-way sex we watched were particularly arousing. Soon we were all naked and somewhat playful.
"We could make porn videos like these. Don't you think?"
Erica asked no one specifically as she reached over to stroke Joe's cock.
"Are you volunteering to be our cameraman?"
Replied Kim.
"You could record me taking both the guys. Wouldn't that be a blast?"
"Several blasts!"
I added in and everyone laughed. Their reaction to my poor joke indicated that everyone was well on the way to getting drunk.
"I think we need to rehearse our roles."
Erica stated as if we needed a reason to have sex. She grabbed my hand and led me towards the bedroom. Kim and Joe quickly followed us.
Upon entering the bedroom, Erica turned, embraced me, and we kissed passionately. My hard cock was throbbing as it pressed against her stomach. I was certain she could feel that, and was pleased by my arousal.
Kim came in and jumped onto the bed and quickly took her favorite position on her hands and knees. She wiggled her cute, curvy ass at Joe. Joe was more than willing to comply with her non-verbal request. He knelt on the bed between Kim's legs and spread her ass cheeks apart as he rammed his engorged cock into her very wet pussy.
"Fuck Kim! Your pussy is so wet and hot tonight."
Joe exclaimed as he pounded his meat into her. Kim liked her sex physical as did Joe.
Erica broke away from me and joined Kim and Joe on the bed. Erica laid on her back at an angle to Kim, their heads close together so that Kim could lean down and kiss her long time lesbian lover. I could see that Erica snaked one hand under Kim and was likely fingering Kim's clit while Joe continued to fuck Kim's pussy.
Erica spread her legs and raised her knees, exposing her own sweet honey pot towards me. I crawled between her legs and planted my face into her pussy and began to lick her wet folds of flesh. I always loved to eat Erica's succulent pussy, and doing so make me all the more aroused and horny. My oral activities didn't last long and I was soon kneeling between her legs. I took her legs and raised them up, placing them upon my shoulders. Lifting her ass off the bed, I was able to easily slide my throbbing cock into her.
I was glad that we had bought a solid built, strong bed. With four of us on the bed, Joe pounding Kim and me fucking Erica, a lesser bed may not have survived.
The sounds and odors of sex began to fill the room. Kim was very vocal and had to break her kisses with Erica as she was gasping for air.
"Fuck me Joe! Fuck me harder!"
Kim implored.
Joe had a firm grasp of Kim's hips and grunted as he rammed his rod into her. Their sex always appeared so animalistic, and I never considered them lovers. In contrast, I felt that I always made love with Erica or with Kim. We were lovers, not just fucking animals.
"Hey Charlie, let's switch."
said Joe.
I looked down at Erica for her reaction. She closed her eyes and nodded her head. It appeared that she wasn't thrilled by the change, but was willing. So I pulled out of Erica and lowered her legs to the bed. Likewise, Joe backed away from Kim's backside.
"What the Fuck?"
Exclaimed Kim.
"I was so close to coming!"
Joe and I quickly swapped places. It appeared that I had my work cut out for me to bring Kim to the orgasm she desired. As I slipped my cock into her waiting cunt, I reached around her hips with one hand and began to finger her clit. She quickly resumed her 'being fucked' mode of thrusting herself back onto my pole as I shoved it forward into her. She made sex a very physical experience.
I could see that Joe lifted Erica's left leg over his right shoulder, causing her to twist sideways in a splits position as he began to fuck her. It was fairly obvious to me that he was totally engrossed in his own sexual satisfaction with little concern for his partner. I once again thought that bringing Joe into our bed was probably not the best idea that I'd had.
Then I noticed that in the position he held her, her clit was somewhat exposed.
"Hey Joe, If you rub her clit, she'll cum really hard."
I suggested to him. I knew, and suspected that Joe knew, that when Erica has an orgasm, her vaginal muscles tighten around her lover's cock and squeezed really hard. For me, this always creates a tremendous orgasm of my own.
As Joe held Eric's leg up on his shoulder with his right arm, he used his left hand to rub her clit. Erica closed her eyes and laid her head back as she enjoyed the sensations washing through her body. Using both her hands, she played with her own nipples, pulling and twisting them as Joe plowed into her pussy and roughly rubbed her clit. It appeared that she was going to enjoy this after all.
We were all grunting, groaning, and saying 'fuck' a lot. I was beginning to sweat, as were the others. I was trying hard to take Kim to a great orgasm. I kept thrusting into her, harder and faster. I was pinching her clit between my thumb and finger.
"Fuck! Fuck! FUCK!"
Kim screamed.
"I'm going to cum!"
And she did at the same time that Joe erupted inside Erica. Joe threw back his head and screamed in a howl.
