After about eight more minutes, Sarah finally crawled out from under the table, wiping her mouth and looking down at Ben's dick. It was almost completely hard again.
"Let's go, I wanna get this done before turning in," she said, as she walked towards the hallway. Eric, fully naked, quickly got up and followed her, his half-hard, freshly fucked and sucked dick leading the way.
Realizing she'd meant me as well, I pulled up my pants and walked out behind them -- the odd one out as I was the only one with clothes on. Sarah led us straight into the master bedroom. I was only a few seconds behind them, but by the time I walked in, she was already on her knees, slowly pumping and sucking Ben's dong, again.
She briefly glanced up at me and said, "Pack up and go. Hurry!'
As she slid her mouth over Ben's almost fully hard dick again, I stepped up to my open wardrobe and started hanging down my shirts, pants and suits. Holding as much as I could in both arms, I then staggered into the guest room -- two doors down the hall.
I had to make four more runs to gather all my stuff and relocate it to my new room.
"I think that's all of it," I said after the fifth run, from the doorway, looking at Sarah, still slobbering over Ben's fat dick.
"Took you long enough," she reacted, jumping up and walking up to the door.
"Now, if you'll excuse me," she added, as she started closing the door on me, "I am going to let your son fuck me in our bed. It's about time I got a proper pounding in that thing..."
Dumbfounded, I just stared at the closed door for several seconds, feeling my cock harden in my pants. When I started hearing fucking sounds about ten seconds later, I realized she meant business. I unzipped, took out my massive dong and started pumping it, hard and fast.
Jealous, degraded to my very core and horny as fuck, I jacked off like a silly teenager while listening to them going at it. Less than a minute later, I splattered my load against the closed door while letting out a long, silent sigh.
Not wanting to listen to their fucking after I'd cum, I quickly zipped up and headed downstairs. But even from the living room and with the TV turned up, I could still hear them moaning and screaming. They didn't even try to be quiet anymore!
I counted at least three big orgasms on Sarah's part and one big one from Eric. Then, after almost half an hour of relentless boinking, everything finally went quiet. About ten minutes later, Sarah tiptoed into the living room, butt naked.
Her twat had clearly been fucked raw. The lips of her labia were red and swollen from the no-doubt hard and powerful fucking. Specks of cum were clinging to the hairs of her trimmed bush. Despite the state her cunt was in, she herself seemed no worse for wear.
"He's asleep. The poor thing is exhausted," she whispered, as she closed the living room door behind her and tiptoed over to my seat. She sank to her knees in between my legs and smiled down at my half-hard dick. Without further ado, she bent her head down and sucked my dick into her warm, eager mouth.
She sucked me off for about two minutes, before speaking again.
"Eric fucked me [bob] so good [bob] in our bed," she whispered, in between head bobs, "Thank you [bob] for being [bob] such an accommodating [bob] little bitch. That made it [bob] easier [bob] and a lot more entertaining [bob] for everyone."
I didn't reply. Instead, I just softly ran my hand through her hair. For the next couple of minutes, I thoroughly enjoyed her warm, loving blowjob. I guess this was her way of thanking me for being such a willing cuckold.
When I was about to cum, she took my cock out of her mouth, pumped it a couple of times and then held my big, purple tip against her chin. I shot out a big rope of thick cum across her half-open mouth, her nose, her left eye... all the way to her forehead.
Then, she promptly moved my dick about a quarter of an inch to the right, just in time for my second wad to splatter across her right cheek, her right eye and into her hair. Without delay, she bent her head further down and started pumping my throbbing dick high above her face, milking out dozens of gooey droplets.
By the time I was finally done cumming, her face was an absolute mess -- she could barely open her eyes. And yet, instead of running off to get cleaned up, she lovingly continued suckling on my dick and licking my balls for quite a while longer.
Of course, this wonderful, stolen moment couldn't last. Suddenly, she poked her head up and looked at me -- my cum still all over her face -- and whispered softly, "Just a head's up. Ben is going to start fucking me up the ass tomorrow. And you're going to watch..."
With those words, she stood up and walked back out of the living room, grinning.
Needless to say that it took me forever to fall asleep -- in my new room, with no bed -- as my mind kept replaying everything that had happened so far. I especially kept going over the last bit of information she'd shared, about getting fucked up the ass...
I didn't quite know what to make of it. On the one hand, I was jealous and angry that she would even consider letting Eric fuck her up the ass -- something she'd never allowed me to do, despite being quite the randy slut in other departments.
But on the other hand, I was intrigued and enjoying the humiliation she was putting me through. Honestly, I was loving my new role as a cuckold. I finally fell asleep -- on the cold floor -- fantasizing about how my son was going to wreck Sarah's asshole.
I must have continued that train of thought in my dreams, because when I woke up the following morning, I had an enormous erection. When I tiptoed out of the guest room, I noticed that the door to the master bedroom was wide open.
When I peeked in, I noticed Sarah and Eric already fooling around -- both as naked as the day they were born. He was fondling her tits, playing with her hard nipples, while she was slowly stroking his big, fat dick. They'd clearly been waiting for me.
"Ah, you're here," Sarah whispered when she noticed me. She stopped what she was doing and grabbed the small bottle of lube from her nightstand, handing it to Eric.
"You're going to do it right now?" I asked, surprised at her timing, stepping into the room.
"Fuck yeah, I want it," Sarah whispered, "I don't wanna wait any longer!"
As Eric carefully began applying lube to his massive dick, Sarah got on her side, facing me.
"Get over here," she whispered, grinning.
The mere thought of what I was about to witness gave me a bigger boner than ever before. I got on my knees right next to the bed, right in front of her. I now had a prime view of what was going to happen.
"You're up, honey," Sarah whispered, glancing over her shoulder at Eric, "Fuck my ass!"
Eric lifted her right leg a little bit and pressed his enormous cock in between her ass cheeks. It took him a few moments to find the right spot, but when he eventually slipped his huge tip into her anus, Sarah gasped.
She started squealing and moaning as he pushed more of his dick into her virgin asshole.
