Brian
I eased gently into Cynthia's pucker for two reasons. The first was because Susan's face was right there, and I didn't want to bump into her. The second reason was simple. Who gets to do this sort of thing, to begin with? I mean, there I was, watching my wife eat another woman's delectable snatch while fucking her in the ass with her husband doing the same. Really, this was a wet dream for the ages!
I was broken from my reverie due to Richard's increasing hammering of his wife's backside. It seemed that he was afraid that he wouldn't get his, for some reason, so he decided to get it really fast. I glanced away from the ladies and looked him in the eyes. Once he focused on me, I motioned downward with my hand, gesturing for him to slow it down. He seemed a bit annoyed at first but acquiesced due to my quiet insistence. That, and the fact that Susan gave him a little kick with her free leg. After a few more minutes, both of the girls had orgasms and pulled apart from each other.
Cynthia
"Okay, boys, how about we change up with a little oral for a while," I suggested while moving to suck Richard's cock. I gave Brian a little wink and he grinned his understanding. I didn't know if Susan had spoken to Richard about the possibility of switching partners, but any apprehension that he may have had melted away as I took his average cock down to the root and licked at his sac while doing so.
Susan
I was a bit surprised by Cynthia's move since she was initially lukewarm to the idea of swapping partners, but I was very happy that it happened. Brian's prick was a good inch or two longer than Richard's, so I was hoping this exchange would lead to me getting his man meat into my eager cunt. Based on Cynthia's tales, he would certainly last longer and was obviously more attentive to her needs than Richard was to mine. I saw that it was Brian that initiated Richard's slowdown of his rampant pounding of my ass. That, along with a good kick to his calf, did the trick, so in my book, I owed Brian anything he wanted from me.
Brian
I was a bit surprised at Cynthia's quick switch, but it was better to do it now rather than drag it out longer. And starting with oral made it an easy transition. Richard seemed to be good, but of course, his eyes were closed as Cynthia kept him on the precipice of heaven while his wife worked my dick like a horny slut. I moved my hands down Susan's shoulders and arms before moving them to her wonderfully firm breasts. I palmed them at first and then tested her nips for sensitivity. She seemed to love all the attention and worked doubly hard to get me off.
Richard
First, I got to fuck my wife's ass, which she rarely lets me do. And I did it while watching her eat Cynthia's snatch. Then when they broke apart, Cynthia couldn't wait to get my big dick in her mouth. This was fucking great!
Cynthia
I had a feeling that Richard was going to cum far too quickly and then cause a problem or leave, which would cause Susan a problem later. With all that in mind, I slowed my contact to extend his and my enjoyment. Several ideas whirled in my mind to keep him excited without letting him cum, and I was having a hard time focusing on just one. Without thought, I released my inner tease and pushed him slowly onto his back. Releasing his cock, I moved forward on my knees and rubbed his knob back and forth along my leaking slit.
"Oh, fuck yesss!" Richard blurted, thinking that I was going to sink down on his hard-on and let him have my puss.
I smiled at his revelry but pinned his hips to the floor while continuing to graze back and forth. With his glans well lubricated from my fluids and his, I moved forward and rested him against my slightly dilated pucker. I rotated in large loitering circles, keeping the head in place at the opening of my orifice.
"You are a fucking Goddess!" he wailed without thought that his wife was less than five feet away.
Brian
Susan and I both looked to see what Cynthia was doing to her husband.
I pulled Susan's face to mine and whispered, "You know that she's only trying to keep him hard for a while, right?"
"I do, but it's not her that I'm jealous of; it's him," Susan replied as we ogled Cynthia's splendid ass, slowly gyrating on the tip of Richard's dick.
"Shall we turn so that we can watch?"
"Yessss," Susan purred in reply.
"Alright, Sexy, get on all fours facing them, and we'll have a little fun ourselves."
Susan turned and assumed the position within arm's reach of Cynthia's meandering buttocks. I moved into position, placing the tip of my prick against her slippery folds, and moved it up and down from her clit to her slightly swollen pink pucker.
"That feels delicious," Susan mumbled as she rotated her hips a little to add to it all.
Intermittently, she'd push back up a bit when I was lined up with her leaking twat, forcing me inside an inch or two and clenching me a few times before pulling back again. Each time, I'd utter a soft "Mmmm" until she released me, as did she. It seemed that we were both enjoying the show and the contact equally.
Susan
As much as I was loving watching Cynthia's ass polishing my husband's knob, I was loving the feel of Brian's pole moving about my backside. I decided to take some control myself and began pushing back every other time he crossed my drooling flower. At first, it was the head popping inside, but each time I needed more. I held back as much as possible until Cynthia moved again, leading Richard's stiffy back to her puss and letting about half of him slip inside. She did this a few times before moving his juice-coated dick back to her ass.
The sight of that did it for me, and I pushed all the way back, sinking Brian's significant hard-on into my depths. We both grunted as he reached forward to keep me from slipping back off. Little did he know, I had no intention of letting him remove himself from my wonderfully stuffed puss. I felt dripping saliva hit the crease above my pucker and move across it. That's when I felt his finger sliding all about my tender little star. That extra stimulation, without the pain from Richard's earlier teenage boy exuberance, was sending me toward another leg-quivering peak. I now understood why Cynthia would never leave this man.
Cynthia
I knew that it was premature to let Richard's dick inside my pussy, even just a few inches, but I needed a little contact too. Besides, I saw that Brian and Susan were having a little fun watching me and playing themselves. It was seconds after I took about half of Richard's prick a few times that I heard a grunt from the both of them and knew that Brian was inside her fully. I moved off of him, placed his tip at my opening pucker, and began to twist. With the extra lubrication from my perpetually slick vagina, Richard moved in easily, and I clenched his glans with my anal ring, which brought us both really close.
Richard moaned when I did it again and I began to stroke my clit hungrily. I pulled off and dropped down again, twerking about as he once again sunk inside me another inch. I repeated the process until my entire body was shaking. At the edge of orgasm, I sank down fully on Richard's stiffy and came all over his belly.
In the aftermath of my acme, I felt Richard's hands on my ass, trying to raise me up. I realized that he still hadn't cum and was right there. Not wanting to deny him any further, I began a slow pumping, which resulted in a pleasant filling of my rectum with his warm seed. I stayed in place, grinding slowly and clenching randomly on his still-embedded dick and loving the slippery feeling inside.
Richard
Oh my God! This sexy bitch teased me to death, came on me, and then let me fill her ass with my cum. She must really love my big dick!
Susan
I knew that between her never-ending quest for orgasms and Richard's wham-bam-thank-you-ma'am attitude toward sex, it would be hard for Cynthia to keep him at bay for long. I'm just glad that she got hers first, and now it was time for me to get mine.
Brian was gently entering my rectum with a finger and flicking my clit with the other hand while still balls-deep in my adoring pussy. If Cynthia was up for it, there would be many threesomes in our future without Richard's knowledge. Brian was stroking my clit perfectly, and the train was running hard toward climax city. Seconds later, my arms gave way, leaving me face-first on the carpet as I wailed aloud and convulsed wildly. Brian kept me there just enough and grabbed both of my hips before I fell sideways.

With my quivering easing, Brian started a slow, solid fuck which pushed me rapidly toward another climax.
"Oh, fuck, fuck, fuck!" I screamed as the second one hit me even harder. This time, Brian eased me down but kept his prick inside me the whole way. All I know is that Cynthia and Brian must have taught each other everything they liked and now I was benefitting from all their knowledge and experience.
Cynthia
Wow, Brian did Susan good. Two orgasms back to back. We were never getting away from Susan now, and I doubt that she'd be inviting Richard to our future couplings very often. Speaking of which, I was still working hard to keep his prick alive, but I guess that he'd need a little more stimulation than just grinding on him to get it going.
Still working his flagging prick with my ass, I opted to give his a little working over too. I fingered my overflowing puss for a minute before directing that same digit toward Richard's pucker. I slimed my way between his thighs, searching for his backdoor. Once I tickled it, I felt a surge in his penis, and he opened his thighs a little more. After another thorough dousing in my twat, I began really rimming him and felt his growth in my backside.
I don't know whether Susan had ever tried that before, but it clearly worked on him just as it did on Brian in the past.
Susan
"Is it working?" I directed at Cynthia.
"You bet my sweet ass it is," Cynthia replied.
"He would never let me touch him there. He said only gay boys liked their assholes played with. So, Richard, are you a gay boy now?" I spouted while crawling forward to Cynthia's ass.
"Um, well, um. She just did it. She's a wild woman," Richard bumbled.
"So it's not that you're gay, but that she just took what she wanted, and you didn't have any choice? Would it have something to do with you fucking some strange in the ass and filling her with your cum," I hammered on, knowing that he had no way out.
"Um...fuck you, Susan!" Richard shouted, unable to come up with anything else.
"Please keep up, Brian darling. I wouldn't want to lose that nice hard cock of yours deep in my pussy," I said aloud to further tease Richard and let him know that I was getting some hard dick.
I got right up between Richard's thighs and began licking all around Cynthia's cock-filled pucker. Then I moved my hands around the front of her and pulled open Cynthia's labia, and tickled her clit.
"You see this, Richard? This is the best-tasting pussy I have ever had, and if you were smart, you would taste it too while she's still here. I mean, who knows whether you'll ever get another shot at this prime slice of womanhood," I said tauntingly to Richard.
"So, are you a lesbo now?" he blurted out.
"Have you tasted the pussy that's right in front of you? If you had, you would know the answer to that question before you asked it," I shouted sarcastically.
"Are you licking her ass with my dick in it?" Richard questioned after obviously feeling my tongue on his shaft.
"Mmmm, yes, I am. Are you complaining?" I said sharply.
Brian must have thought that now was a good time to distract me and began sliding in and out of my pussy once again. With each thrust, I'd bump my nose against Cynthia's ass which only made me lick her harder and flick her clit faster. As I approached another orgasm, I was certainly going to take her with me, whether Brian came or not, but I hoped he would.
Through ragged breath, I begged, "Cum in my hot little pussy Brian. I want to feel your spunk filling me up."
I said it as much for Richard to get him jealous as for Brian to get him going. Brian started giving me more speed and force as his thumb sunk into my delighted asshole. I knew I was close and felt Cynthia's tremors as well. I only hoped that Brian was close enough for us to have at least a three-way explosion of cum and screams.
Brian
For the first time today, I was getting very close to cumming, and with Susan's plea to fill her hot little pussy, I decided to go with it. I could tell that both of the girls were already on the brink, so I sped up just enough to take me to Valhalla with them.
Cynthia was the first to go, wailing, "Oww, fuck, Susan, you wonderful bitch!"
Susan was right behind her and bit Cynthia's ass as before she squirted all over my pounding penis. Her growl was muffled by the mouthful of Cynthia's right buttock that she held onto. I was next as I slammed into Susan and pumped quite a load of hot spunk in her welcoming vagina.
We all recovered for a minute or two before I began to back away from Susan's sloppy puss. I saw her hand shoot back to stop the leakage. She shakily began to stand and stumbled around Cynthia, who was still poised on Richard's cock.
Susan straddled his face and said quietly, "If you ever want any more of that prime ass currently wrapped around your cock or this pussy hovering over your mouth, then you'll eat me like a man."
With no response from Richard, she removed her hand and dropped her leaking box right down on his mouth.
Richard
Susan seemed nearly as wild as Cynthia, and it seemed that Brian was good with everything going on between all of us. I'd often fantasized about this very thing and hoped that it would happen with Susan. I guess that I'd been too much of a stick in the mud on the surface. I should have shared my fantasies with her, especially after some of the girl get-togethers that I knew she was having. But here I was with my cock buried in Cynthia's hot little ass and Susan's cum-filled pussy plastered to my face. I needed to take advantage of this situation and prove to Susan that I wanted it all, just like her.
I swiped my tongue through her sloppy hole and sucked in the cum that was already pouring into my mouth. The taste was a fantastic combination of Susan's already tasty juices and Brian's slightly salty addition. I dug into her furiously, wanting more and more of her wonderful concoction. My burrowing tongue also seemed to have a tremendous effect on Susan. She began squirming all over my face while bellowing, "God, yes! That's it, you whorish bastard! Suck that cum out of my slut cunt. Make me orgasm again while you do it!"
I kept sucking, lapping, and drilling into her pussy until she stopped cold and squirted down my throat like I used to do to her back when she still gave me blowjobs. I continued to suck at her puss and began to pump into Cynthia's ass. That's when I pushed Susan forward just a little and tongued her pucker deliberately. The idea just came to me when I remembered that I'd already filled Cynthia's ass once, so it would be very full after another cum. I wanted to show all of them that nothing was off-limits for me if they'd let me continue to play with them.
I seized Susan's glutes and pried them open to get deeper into her opening star. Susan began to shiver and started fingering her pussy while I tongue-fucked her into heaven. Another squirting climax coated my face and chest just before I filled Cynthia's ass with my own fluids.
Once Susan stopped shaking, she smeared her cum all over my face as I lapped at every bit of it that I could. After another minute or two of cleaning her front to back, Susan raised off of my face and said, "Cynthia, I think that it's your turn to ride Richard's cum-sucking face. I think he needs another load or two."
I watched as Cynthia slowly slipped off of my shrinking dick and plugged her ass with a finger. She moved forward and plopped right down on my mouth, just as Susan had done before. It was then that I felt a mouth envelope my softened member and give it and the rest of my groin a tantalizing bath.
