A few minutes later, she came out of her sex fog to exclaim, "Son, we need to do this more often - a LOT more often! Whenever Alan Junior is in me, it's like a slow orgasmic buzz in my cunt. And whenever you're suckling me, there's a different kind of buzz in my tits that's just as wonderful, and maybe even better. But combining them? Oh Lord! It's like a whole new thing!"
Katherine sighed longingly. "Wow. Mom, you're so lucky."
Susan swiped a spare drop of milk off the lower slope of her left breast, and fed it to her daughter. "I know I am. But this'll be you someday too. Just imagine your brother splattering his fertile baby batter inside you and knocking you up. Then you'll waddle around with huge tits and an even huger belly, and he'll fuck and suckle you ALL the time."
Katherine mentally drifted away, as she envisioned a glorious future day when her brother had impregnated her. In her fantasy, she sat up on him and rode his cock, despite the fact that she had a very round belly. Her tits were the size of Susan's, and her breast milk was shooting out everywhere.
She grinned from ear to ear as she daydreamed this. She mumbled, "Sweeeet! That is sooooo going to happen! And soon!"
"What?" Alan muttered.
"Oh, nothing," she replied, while idly playing with his balls. "But have either of you ever thought, and I do mean really, seriously, deeply thought about the fact that all this wonderful, spermy cum that we bathe ourselves in daily, that any little bit of it could start a new life? Is that not completely mind-blowing, or what?"
Susan replied, "I do! I think about that ALL the time! Especially when I'm guzzling it straight down my throat. Angel, never forget that Tiger's yummy sperm is a sign of his virility and potency! I just know he's gonna make you a happy mommy-sister before too long."
Katherine thought, "Mommy-sister!" I love the sound of that! She started bouncing on the bed impatiently. "My turn! My turn! Big Baby Rattle Brother, do me bareback! And can you suckle my tits too, so I can kind of pretend?"
He chuckled, especially since he was already doing both of them bareback anyway. "Sure. But remember, go slow." He was eager to make a switch already, since Susan's subtle pussy squeezing was bringing him too close to the edge.
The "stealth fucking" went on for over an hour, and Alan hadn't even come close to cumming, so he didn't have to struggle with his PC muscle. It was very low stress for him, and nothing but pure enjoyment. He decided that it was something he'd want to do a lot more of in the future. Plus, his penis had become so accustomed to long periods of friction and stimulation that he wasn't even sore when it was all over. He noted to himself, only half-jokingly, that his penis was probably starting to develop a leather-like hide, in the same way that the fingertips of beginning guitar players develop calluses.
However, Susan and Katherine were tiring more quickly than he was, even though they had traded places several times. After all, they were doing virtually all the work, and the fucking had gone on for so long that they both got tired from clenching and unclenching their pussy muscles. Eventually, they were "forced" to vary it up with handjobs and blowjobs. Both women had several orgasms. But whatever they were doing, his erection was always the center of attention.
Then Susan surprised her children by yawning ostentatiously and saying, "It's been fun, kids, but this old broad is getting pretty sleepy. Angel, I think you and Tiger need some special one-on-one time. And Tiger, don't you think it's time you spent the night in your sister's bed? She's not really going to feel as dominated as she should be until she wakes up in the middle of the night, in her own bed, and finds your stiff cock halfway down her throat before you stuff it all the way into her cunt and ass. That'll really show her just who the boss is around here."
"Go, Mom! Woo-hoo! Great idea!" Katherine enthused. "And Brother, if we do that, I promise I won't even say the 'C' word... much." She giggled.
Alan asked, half-seriously, "Mom, are you sure you're feeling well? I mean, you're practically kicking me out of your bed here."
She kissed his cheek with a smile before ruffling his hair in a motherly way. "Son, I'm not kicking you out of my bed, I'm kicking you into hers. Of course I'd love to spend hours just taking turns slurping on your cock, when you're not busy fucking one of us, that is. But we do need to get some sleep eventually. More importantly, I worry that I've been far too much of a cock hog lately. It's her turn."
He replied, "Okay. Actually, I was going to suggest sleeping in Sis's bed tonight anyway, so this works out well. But Mom, I'm mad at you."
She blinked in confusion. "Mad?!"
He said, "Yes. What you did, suggesting I sleep with Sis, is unforgivable. Tomorrow, I'm afraid I'm going to have to give you a very thorough spanking. I might even have to tie you up first, just to make sure you learn your lesson."
Susan's face beamed so brightly that it practically turned night into day. "I stand corrected," she giggled as she rubbed her clit. "I promise I'll be a good mommy from now on."
"You'd better," he mock blustered, but he was all smiles too. "By the way, you're not even gonna kiss me good night?"
It hardly seemed possible, but her smile grew even bigger. "When did I ever say that? Come here. Come sit on my big tit-pillows. I'm not in THAT much of a hurry. I want you to 'kiss' my tonsils with your cockhead for a few minutes. Feeling your fat cock slide between my lips is just the greatest thing in the world! Then I'll have really sweet dreams, even if you don't give me your sperm."
So he sat on her and fucked her face for a little while, but at a slow pace, in keeping with the mellow mood they all felt.
Katherine crawled between her mother's legs and lapped on her pussy lips and clit until both she and Susan climaxed again.
Then her two kids got off her.
Susan commented, "Phew. That was great. I had ANOTHER big 'O'. It just goes to show that the more one gives, the more one does receive. I'm too wiped out after that to get up and brush my teeth and such. I'm just gonna have to go to sleep with the taste of my son's pre-cum in my mouth."
"Poor you," Katherine teased and giggled.
Just before Susan closed her eyes, she looked at her children and smiled benignly. "Now, THAT'S what I call a good night kiss. The two of you have made me the happiest mommy in the world. And Tiger, I know that collar didn't cost you much, but it's the best gift anybody ever gave me, bar none. I can go to sleep knowing I've been totally tamed and owned by my master, and that gives me a greater feeling of contentment than you'll probably ever realize."
"I'm glad it worked out so well, Mom. To be honest, I've had so much fun this evening that I've almost completely forgotten I even took part in a fight today. And my hands don't feel bad at all. I might even take off most of the bandages tomorrow. I'm surrounded by so much love and care that I feel humbled. Thank you."
He thought, Man, if that's the reaction I get from giving the collars, I can't even imagine what'll happen when I give them their rings! He walked up to her and kissed her on her forehead. "Nighty night."
She answered dreamily, "Nighty night. Don't let the bedbugs bite. But do let your sister nibble."
While he stared at his beautiful mother just lying there contentedly, he thought, This is great, as usual, but I'm a bit bothered by the shift in the power dynamic. How can Mom be an effective mother if she's calling me "boss" and "master" all the time? So he asked, "Mom, are you okay with everything that's happening here?"
Suddenly, Susan opened her eyes wide, and her eyes lit up. She reached out and clasped Alan's hand in one hand and Katherine's hand in her other. "There's just one more thing I have to say. I still consider myself a very religious person, but I have no moral or religious qualms about what we're doing. None. I figure that what we're doing feels so good, it can't possibly be wrong. I don't care what any preacher says. They're wrong! God wouldn't make a cruel joke like that."
That didn't address his concern at all, but he didn't want to spoil her blissful mood by pressing the issue at the moment.
She closed her eyes with a great big smile on her face. "Good night, my loves. Tomorrow's gonna be another wonderful day, full of fat son-cock sliding down my throat, plowing into my cunt, and general total sexual servitude. Maybe I'll even get it in the ass. One can hope! I love you both, so much!"
She thought, And tomorrow's going to be an extra special day, because he promised me an "extra thorough spanking," and he might even tie me up for good measure! I can hardly wait to go to sleep now, because that will bring me that much closer to my promised spanking. But on the other hand, I'm so excited that my body isn't ready to sleep. Ah, the "problems" a big-titted sex slave mommy must face! She giggled in glee to herself.
Actually, he had just been joking about the spanking, but she didn't realize that.
Alan and Katherine each kissed their mother on her forehead. Then they walked out of the room hand in hand.
He said, "Come on, Sis, enough of this stealth stuff. It's time to give my Number One Fuck Toy what she deserves: a right and proper fucking."
She bounced lightly on her heels. "Yes, please!"
