Alan looked down at himself. His weary penis had been flaccid seconds before, but now it was rigid again. This is insane! I'm sorry, Mom, but I have to fuck you right here and now! I don't care if this is called motherfucking; I don't care about anything anymore but fucking you! You're begging for it! I'm going to give it to you!
He stood up. His erection was pointing towards his mother, and it seemed to have a will of its own. It was homing in on her pussy as she writhed on the floor. He got down on his knees and began moving in over her. He had a very depraved and lusty look in his eyes.
She suddenly looked up at him and immediately sobered up. "Tiger! What do you think you're doing?!" She could tell he intended to fuck her, and she realized she had to do something fast to stop him.
She lunged forward as if she were attacking him. Her mouth aimed for his boner and it connected; she took his erection into her mouth as he fell backwards towards the bed. The gobs of cum that remained on her face and tits flew in every direction.
Alan hit the floor on his butt, and then his back hit the side of the bed. His mother still had her mouth wrapped around his cock. He was somewhat surprised that she had managed not to bite it or otherwise hurt it as he fell.
As they both adjusted and recovered, she thought, Oh my God! I have my son's member in my mouth! Actually, I should call it a cock now because I'm cocksucking! I'm a naughty, big-titted cocksucking mommy, hee-hee! It feels so GOOD! So THICK and BIG!
MMMM! Suzanne was so right about this! I can tell right away that I love it! Mmmm! I can barely stretch my lips around it. Hey, Suzanne was right about that too! She's such a genius!
Her entire body trembled with lust as she focused fully on the feeling of having her mouth filled with her son's cock. Everything about it was too thrilling and arousing for her to handle. She had to take some moments to adjust to breathing through her nose, but even that excited her beyond belief.
She felt as if she'd had an epiphany. This is major! Somehow, I can tell that this is a major turning point. It just feels so right to have my mouth stuffed with my son's massive cock! So wrong, but so right too! I'm going to suck him off to completion now, as best as I possibly can. But I can already sense this isn't going to be the only time. Oh no! In fact, what if... what if I were to start stroking and sucking him all the time?! What if I totally fall in love with doing it?! OH GOD! Suzanne would approve, but it's just so naughty! But I can't help it!
She placed her hands on his knees and immediately began sucking vigorously. It was clear she was inexperienced in cocksucking, because at first she gagged repeatedly. But after a few attempts she learned not to try and take it in so deep. Her tongue and hands weren't really doing anything, because sliding her lips back and forth over his sweet spot while creating considerable suction took all her concentration.
He didn't care how clumsy or inexperienced she was. The mere fact that his prudish yet super sexy mother was the one blowing him was such a rush that he was nearly delirious. He grabbed her by her long, dark brown hair, and yelled, "Yes! Yes! Suck it! Like that! Keep sucking!"
With one hand he reached down and tried to grasp her boobs, which were now swinging wildly backwards and forwards in time to her bobbing head. But he was moving and so was she, and he couldn't concentrate, so all he could manage was some rough groping.
Still, he found that extremely exciting, since it was the first time she'd ever allowed him to touch her bare boobs with his hands.
Susan didn't like that though, fearing a repeat sexual escalation. So she paused long enough to help him sit up on the edge of the bed. She figured that her rack would be more out of reach if she sucked him while kneeling between his knees. Besides, there was something about that position that turned her on even more, at least in part because Suzanne had been hyping it so much of late.
He readily accepted the new position, reclining until his back rested against the wall. While it would have been nice to grope at the huge breasts he'd secretly lusted after for years, he was so far gone with pleasure from her steady cocksucking that he could hardly focus on anything else, let alone think clearly.
As she resumed her bobbing, she thought, Suzanne is a fellatio expert; that's obvious. She's got plenty of experience, that extra-long tongue of hers, and a naturally sexy attitude. I'm not about to embarrass myself compared to her. This may not be the right or moral thing to do. I don't know. Sometimes, the good Lord just doesn't give a clear sign. But it's what I'm doing, and darn it, I want to be as good as Suzanne is! I'm gonna put all my reservations aside and suck this fat cock like my life depends on it!
Susan quickly learned that a good technique was to suck as deeply down his shaft as her mouth could manage and then pull almost all the way off, and repeat, in an imitation of fucking (even though her definition of deep at this point wasn't very deep at all). Normally this would have set him off quickly, but since he had just cum twice in the last half hour he found that he could keep going and going.
Susan's whole body began bucking wildly again as she was wracked by more orgasms. Her private parts weren't being stimulated directly, but the sheer thrill of sucking her son's cock had aroused her more than anything in her entire life. All her reluctance and resistance vanished as she totally succumbed to some kind of cocksucking mania.
She tried to remember and implement the blowjob advice that Suzanne had given her, but it was hard to do. She was loving every last aspect of the experience, and she was as happy as she could be merely from having her son's cock filling her mouth. But from time to time she remembered her desire to become as good at this as Suzanne. She still was too far gone with lust to try out Suzanne's tips, but she did remember to focus more on his frenulum, the "sweet spot" on the inner side just below his cockhead.
She mostly kept her eyes closed to help her focus fully on what she was doing. Besides, that reduced her embarrassment a little bit. But from time to time she would peek up at him and see the rapturous expression on his face, which delighted her to no end. Before long he was continually moaning with pleasure, and that truly was music to her ears. Gosh, this is such FUN! Tough, but fun! I'm making Tiger so happy that I can't believe it! He's practically going out of his mind, thanks to ME!
After a few more minutes, she removed her mouth from his soaked boner and began jacking it off instead. For one thing, her jaw had grown tired surprisingly quickly, and for another she was eager to talk to him. Her eyes sparkled with delight, and there was cum and saliva drooling down her chin. "Tiger, Mommy is a real cocksucker now! What do you think of that?"
"Oh, Mom!" He was beyond speaking. There were no words to convey his joy. He was riding along the edge of orgasm, yet somehow he wasn't cumming quite yet. It was incredible.
She panted, "It's so good! It's just like Suzanne said it would be. Better, even!"
Her whole body bounced up and down like a pogo stick in time to her stroking. She sat on her legs with knees bent, with one foot between her legs where she was trying to press it into her pussy. As she bounced, she was able to gain a small measure of satisfaction by using her heel to rub against her clit. She could tell she'd be having more powerful "tingles" soon.
Then she had the great idea to lick around his cockhead (and especially over his sweet spot) while her hands stroked the rest. Her lips had been very busy, but her tongue hadn't really gotten involved before that.
She took to that combined action like a duck to water. She loved it so much from the get-go that she was frustrated that she hadn't started licking his erection years earlier. Mmmm! Mmmm! MMMM! So good! So yummy! He has such a POWERFUL and THICK cock! It's like I'm trying to tame it with my tongue by making him squirt, but that's no easy task, that's for sure. I could keep at this all day long! Mmmm! And it seems that every time I lick right... here, I'm rewarded with one of Tiger's lusty moans. Mmmm! Especially when I lick him right HERE! She lapped fervently all over his sweet spot.
He thought, Holy fucking hell! That feels AWESOME! Mom's even better at licking than she is at sucking! Dang! Mom is licking my cock! I can't believe it!
Meanwhile, her hands flew back and forth over his turgid pole, even as she kept on licking all over his most sensitive spots.
Both mother and son were now truly beyond coherent speech, so they just screamed and moaned unintelligibly.
Finally, with the loudest groan yet, Alan began to shoot his seed.
Susan rapidly put her mouth back over his erection and prepared to swallow it all. Feeling him cum in her mouth had been a great fantasy of hers for days, ever since Suzanne had started talking about it, and now it was actually happening to her. She felt like she'd just won a million dollars.
He came, and came, and came again.
She rubbed her clit against her heel and had another orgasm, her best one yet.
She was amazed at the sheer amount of cum that rocketed into her mouth. But her inexperience betrayed her again; most of it dribbled out of her mouth and down her cheeks and chin.
Both of them finally fell back in exhaustion.
Alan almost passed out on the spot, he was so spent, but he managed to stay conscious. He again looked at his mother. Now most of three loads of cum had landed on her face and chest, minus all the gobs that she'd eaten or swallowed directly.
She was rubbing his hot cum all over her face, working it into her skin. Then she took her cum-soaked hands and rubbed the rest all over her body, writhing like an exotic dancer.
"Oh!" she cried. "Tiger! My special son. You've covered me! Covered me in cum! So good!"
Her body bucked with erotic spasms, and he wondered if she'd orgasmed yet again. But eventually her hand movements became slower and slower, and finally stopped altogether.
