Just a few moments later, she pulled away from Sean, pushing him back with a hand, his massive cock suddenly coming into full view again, rigid as steel, glistening from having just been buried in Nora's sopping cunt. He was stroking the shaft slowly; still rock hard and fisting himself, obviously he hadn't cum yet. Nora looked over at me and Tim, still fucking away.

"Right after I cum I can't stand having him inside me, at least for a while. He's just so huge!" Nora said, looking back at Sean with a sassy smile, trying to make him feel good despite the fact that his thick tool was no longer engulfed by her tight, clinging cunt, pointing to the tool now. "Can you believe that he actually has been begging to fuck my ass? He wants to work that up my asshole! Now you know I've been fucked up the ass, Amy, I've told you so. By normal-sized guys. But a girl can only take so much back there."

So with those words she was both flattering her boyfriend about the immense size of his penis, and denying him access to what he wanted, her ass.

Naturally hearing all this gave me ideas, wicked ideas! I knew how much Tim liked taking it in the ass. I did it to him like that a lot, and he loved it. I even brought a strap-on with me on the trip, thinking we'd have our own room and I'd be able to use it on him. Tim even confessed to me that he'd taken it up the ass a few times with guys, and really liked it.

So now I couldn't help thinking whether Tim would be able to take on Sean's tool. Here now, while he was still fucking me, with the four of us in the room. Sean, as far as I knew, was straight but he looked so fucking horny standing there and watching us fuck as Amy slowly stroked his shaft. So I started wondering what he'd think of fucking Tim's ass. Or what Tim would think about it.

I looked Tim in the eye as he kept thrusting into me and he must've read my mind.

"Are you thinking--?" he whispered.

"Yes I am; would you?" I asked.

"Wow, that would really be something," and right away I could see my boyfriend was game.

"I know one ass Sean may be able to fuck," I said, turning to Nora as I reached around to spread Tim's cheeks wide open, "this one."

"Holy shit! Are you serious!?" Nora just about gasped as her eyes went wide and a big smile creeped up on her face.

"We can try," I said hopefully as Nora looked at Sean.

"What do you say, babe? You wanna fuck yourself some ass, don't you? How about some nice tight boy ass?" Nora knew Tim took cock, though whether he'd be able to take this cock was still to be determined. "I'd love to see you fuck a guy in the ass with that monster tool of yours, babe, fuck Amy's cute boyfriend. With that dick being so huge you're not gonna get too many chances to fuck ass. But at least Tim's willing to give it an honest shot."

Sean looked stunned but his tool sure stayed nice and rigid as his eyes drifted sideways to look over at Tim's ass, Tim pumping away at me. Now Tim has a cute, tight ass, smooth as a baby's, but hard and muscled. And holding Tim wide open now, I was showing off the prize, the target, Nora and Sean both gazing down.

"Come here, Sean," I purred seductively, wagging a finger at him as Nora looked on with bright, amazed eyes gleaming wickedly. Tim sauntered over, his massive eleven inch cock, rock hard, bobbing slightly as he walked the few steps to our bed where Tim was pounding away at me, his strokes slower now as he turned his head to watch Sean.

I reached over and wrapped my hand around Sean's cock, tugging at it, the cock so thick I couldn't even get my hand all the way around the spectacular girth.

"Can I?" I said teasingly to Nora, licking my lips.

"Be my fuckin' guest," she said in husky whisper as I craned by neck a little and started to lick his knob, then wrapped my lips around Sean's cockhead and started sucking it, Tim's face inches away. As huge as his dick was staring at it, as immense as it felt as I wrapped my hand around it, now that I had it in my mouth I was just awed at the size the tool, and way it just crammed by mouth. And now I knew something else about Nora, my closest girlfriend, I knew what her cunt tasted like as I lapped up the sweet creamy pussy glaze that covered Sean's cock.

"Have a taste, babe," I said to my boyfriend, pulling away and holding Sean's cock out for him, feeding it to him. God, my heart was beating so fast and I was so turned on. Not just because of the grade-A fucking I was receiving courtesy of Tim's big beautiful cock, but because I was finally going to see Tim, who I knew was bi since we first hooked up, have sex with another guy.

Sean just knelt there as Tim took his cock between his lips, sucking the knob as he took hold of the club-like shaft, taking it from me. Tim groaned, loving it. He may've been straight but he sure didn't mind having Tim sucking his big dick, and it probably turned both guys on even more that Tim was fucking me as he was sucking Sean.

Nora, meanwhile, was panting excitedly, her hand between her legs, strumming away, even though she'd enjoyed a monster orgasm only minutes ago.

"Fuck his face, Sean, fuck his cocksucking mouth!" Nora urged, pushing back on Tim's head, Sean now really ramming that cock between my boyfriend's lips, crazed with arousal.

"Suck that fucking dick, bitch!" Nora growled. She knew Tim and knew he was a masculine jock, but now he was sucking her boyfriend's cock and nasty slut that she was, she couldn't help mouthing off like that. And she made me feel wickedly nasty too as I gazed into Tim's eyes as he sucked away.

"Straddle my face, Sean," I told Nora's boyfriend who now flung a leg over. I was looking up at Sean's big balls and beautiful ass, and the underside of his stiff dick as Tim sucked away

"Are you gonna do what I think you're gonna do?" Nora cackled.

To answer her I didn't have to say anything. All I did was grab hold of his buttocks, spread them wide, and slid my tongue into the crack between those smooth, hard muscled ass cheeks, finding his hot little hole. I had once told Nora just how much I liked to rim guys.

"Oh, yeah, look at you! You love eating my boyfriend's hot ass, don't you? Just like your boyfriend loves sucking his huge dick," Nora hissed nastily.

With my tongue working his asshole, all I could do was grunt, cupping his big balls in my hand as I lapped away at his puckered hole, his powerful muscled thighs pressing against my cheeks.

"Ok Sean, now switch," Nora told her boyfriend after a few minutes of this, me and Tim orally ganging up on Sean's cock and ass. So now Sean lifted himself and turned and there was his huge cock staring me in the face again. Naturally I took it in my mouth and kept up the sucking.

"Now I want to see you eat Sean's ass, you slut, while he fucks your girlfriend's face!" Nora hissed nastily as I reached around to spread Sean open, giving Tim room to dig his tongue into the sweet spot. I'd often heard how much gay and bi guys like to rim ass, and my boyfriend was proving himself an ass-licking champ as he lapped away, lapped while I sucked. Tim always loved licking my ass and I figured he picked up at least some of his moves rimming the hot assholes of studs like himself. Sometimes I like to fantasize how guys like Tim, cute college jocks, secretly jacked and sucked and rimmed each other after they came out of the showers in the gym locker room. Now I didn't have to fantasize about that anymore. It was happening right now, on our hotel bed, here in the spring break paradise of Cancun, Mexico.

I unclamped my lips from Sean's cock and told him that was enough. Enough cocksucking, enough rimming. It was time for more fucking. I was still getting sweetly fucked by hard-pounding, long-lasting Tim. Now it was time for another kind of fucking, ass-fucking, the fucking of male ass, of Tim's ass!

"Get back here, babe," Nora ordered Sean, " it's time to fuck some ass, time to pack that big dick of yours up some tight ass."

So Sean stood up, his hand going immediately to that overheated dick of his, slowly stroking the massive log again. That dick was eleven thick inches long, and every thick inch had been well-stimulated. Nora had sucked it then welcome it into her pussy for a sizzling fuck. Then we and my boyfriend had given Sean's cunt-scented cock even more head. Now it was time for this dick's final destination.

With Sean no longer kneeling up by us, or sitting on my face feeding me and Tim ass and dick, I could gaze up into Tim's eyes as he just kept on fucking me. We kissed, our two mouths just having serviced Sean, front and rear, a new intimacy between us as we shared something we had never shared, another man's cock and ass.

"I love this, Tim," I whispered to him, "I love that you're doing this, that we're doing it together."

"Shut the fuck up, you two love birds and spread that ass for me," Nora cackled teasingly, "And where's your lube? You two ass fuck, so you must have some lube around."

Now I reached around and as I gazed lovingly into Tim's eyes, I spread his smooth, perfect ass cheeks wide open, knowing I was exposing the hole to Sean and Nora, who were standing behind us.

"Mmmmmmmh, baby, look at that," Nora purred as she took hold of Sean's cock again and stroked it some more. I told her which bag the anal lube was in and she went and got it. Nora was right, me and Tim ass fuck a lot and I made sure to bring lube with me on the trip.

Laura set the lube down and then knelt down behind Tim's ass as I kept holding his cheeks apart.

"I think I'll have a taste first. After all, Amy licked your asshole, Sean."

And then I could feel Nora's cheeks as she pressed her face into Tim's ass and started licking his hole, slurping away, Sean looking down watching as his girlfriend bend down to lick another dude's ass.

"Mmmmmh, I know much you love a wet tongue in your sexy ass," I sighed to Tim, "she's starting to get you ready for that big dick you're about to take.
