So the three of them changed locations.

Susan once again knelt between his legs. She was still hot to trot, despite the delays. However, she was dismayed to see his penis had shrunk to a half-hard state at best. She cooed, "Here Tiger, if you're going to reach eight times today, it would be good if you could do it twice before school. This is a good opportunity to practice the stealth stroking I was talking about as well. Let's get this thing back to its magnificent ten-inch length!"

"Um, actually, it's more like eight," he said, closing his eyes again to cut down on the stimulation.

"So you say, Son, but I know its real size. You just like to be modest." She started stroking it. Then she turned to Katherine sitting next to them and asked, "Don't you need to take a shower or something?"

"Yeah. I might as well get it done now." Katherine quickly rushed out of the room, planning to take her shower in record time.

With Katherine gone, Susan turned her full focus to stimulating her son's penis. But she frowned at its semi-hard state, and kept on frowning, because it didn't pop up to full hardness in a few seconds as it usually did. She tried everything she could for about five minutes, rubbing and sucking him every which way, but nothing seemed to help - no matter what she did, she couldn't manage to get it more than partly erect.

She didn't know that he was trying to think of the most vile, disgusting, non-sexual things possible. He was also either keeping his eyes closed or looking away from her as much as he could get away with. Even so, he wouldn't have been able to fend off her sheer sexiness and stimulating efforts except for the fact that his penis was still worn out from eight climaxes the day before.

Katherine returned quickly after taking a very quick shower. She hadn't bothered to put on any clothes at all, because she knew there was still lots of time for more sexual fun before school.

She took a look at her mother's grim frown and the flaccid state of her brother's penis as it was being licked and stroked before making some disapproving "tsk-tsk" sounds. "Mom, what's going on? Don't tell me it's been five minutes and he still hasn't gotten hard?"

"I know!" Susan said with great worry. "I'm working on it."

Katherine noted, "It was hard enough when I was stroking it, before you told me to stop."

Susan looked up at her and said, "I'm more than aware of that. Unfortunately, there was a few minutes of no stimulation between when you let go and I took over, and apparently that was a few minutes too long."

There was silence for a few moments, before Katherine said saucily, "Maybe that's the reason, or maybe it just takes a sister's touch."

Susan had just started suckling on his cockhead, but that prodded her to pop his dick out of her mouth and complain in a huff, "I think a mother's touch is just fine, thank you very much!"

Turning to look up towards Alan's face, Susan asked, "What seems to be the problem, Tiger? It usually takes more than one orgasm to cause you to give up, and even then you usually eventually rebound, and keep doing so until it's just too painful for you to continue."

"Believe you me, I want to get hard so bad. But I think yesterday wore me out. It's like if you don't sleep enough night after night, one day it all catches up to you and you crash. That's how my dick feels today." That was true enough; however, he failed to mention his deliberate effort to stay flaccid.

Susan was visibly concerned. "And on a Tuesday, no less. Isn't there anything I can do? We still have fifteen minutes or so before you have to leave for school. I want those to be minutes of pure joy for you, Son. You deserve nothing less." She sighed, temporarily giving up stroking him.

He sensed it was time for him to move his scheme to the next phase. "Well, perhaps if we try something new, that could raise my excitement level. You know, earlier, when I was running my hands over your inner thighs, and Katherine's too, my dick was so hard that-"

Susan stood up, and started pacing around. "No! You're probably right that that would work, and I'm so desperate to suck on your cock and provide your medical treatment that I'd agree to just about anything, but not THAT! Sorry, but that's one boundary that we can never cross." She was adamant on the subject mainly because she felt, and with good reason, that if she let him play with her pussy he'd be fucking her before long.

"Well..." He pondered that for a few moments. He was bummed that he couldn't push the envelope on that rule, but there were other rules he was eager to break as well. Addressing both Susan and Katherine, he suggested, "Since both of you are here, what if you kissed each other on the lips? That would be really sexy. In fact, just thinking about it is already starting to help out." He looked at them, which was plenty of inspiration, and let his penis engorge.

"Hmmm." Susan thought out loud while checking out his new boner. "Maybe that would be okay..." But then she changed her mind. "No, on second thought, that goes too far. I've been far too lax. I have to put my foot down." She sighed and sat down in a chair.

Katherine immediately came over and sat in her lap. "Oh Mom, don't be such a square! Please? Pretty please? I feel like you're always helping Alan out, and I never get to help. Here's my chance to contribute to his medical treatment. He needs constant visual stimulation. We have to keep that big dick of his hard and squirting cum. Won't you let me help just a little?"

Alan was trying hard to get his penis to go back down. Now that he'd let his resistance go, it just kept getting stiffer. That could take away the justification for a hot lesbian kiss, and he certainly didn't want that. The mere fact that his fully nude sister was sitting on the lap of his equally nude mother was making him far too horny. He carefully tucked his erection between his legs so it couldn't be seen.

Luckily, Susan was disconcerted and distracted by all the nudity, and especially by the way her daughter was now sitting in her lap. She had her hands full with that situation, so to speak, so for once her eyes hadn't been glued to her son's penis. "We shouldn't be doing this. It's improper."

But her protests were feeble, and Alan knew it. He said confidently, "Mom, DO it!"

Katherine scooted up closer and put her hands on her mother's shoulders.

"Can't we at least put some clothes on first?" Susan asked.

"No," Alan said with surprisingly strong conviction. He really, really wanted to see them kiss.

Susan thought, Dear Lord! How can I say no to him when he talks like that? Well, if we're gonna do this, we'd better get it over with soon, because there's too much naughty touching going on!

She didn't know what to do with her hands. At first she held them away from touching any part of her daughter's body, but realized that to keep doing so would be very awkward, so she put them on Katherine's hips.

Meanwhile, the way Katherine was sitting, Susan couldn't help but press her heaving, huge tits into Katherine's stomach. She could feel the heat radiating from her daughter's pussy, just as she knew Katherine could feel her pussy heat, but she tried to ignore that.

Katherine leaned even further down to look in her mother's eyes from inches away, which also caused her own ample boobs to press into the tops of her mother's even more massive orbs. She said, "Mom, think how important it is that Brother gives up another big, spermy squirt before school. Don't you think it's extremely critical that you slip and slide your lips all up and down and around his thick, tasty pole for as long as you can before we go to school?"

"Well, of course! That goes without saying."

Katherine kept talking, giving Susan no time to think about how they were positioned against each other. "Just imagine him sitting in school with blue balls for hours and hours, with that painfully aroused huge log of his just trapped there in his shorts, untended. When instead he could be shooting all that gooey goodness down your throat in a matter of minutes. All we have to do is kiss. That's no biggie."

Just as Katherine was hoping, Susan's brain was fogged by their closeness and touching, not to mention the talk of pleasuring her son's "huge log." Her eyes and mouth were so close to her daughter's that Susan felt a strong desire to move her head slightly forward and kiss the girl on the lips. But still she said, "That does sound pretty dire... I don't know... It seems so improper..."

"Oh please?" Katherine started bouncing up and down as if she were five years old and asking for a new toy. "Please, please, please?"

The bouncing stimulated Susan's body and fogged her brain even more. "But isn't that kind of lesbian, to kiss another-"

"Of course not, Mom! It's just a kiss. It's not like we're doing something sexual." Katherine slid forward and shifted her weight so she was more on top of her mother's right leg than her left. She made sure that Susan could feel her shaved pussy riding against the skin of that leg. "Besides, just think of that thick meat sliding between your lips. Think of that cum explosion just waiting to pour down your throat!"

"I don't know. The Bible says-"

Seeing that Susan was still undecided, Katherine realized that pleading wasn't the most effective approach. Instead, she put on her best authoritative voice, and interrupted, "Mom, don't think, just do it. You keep relying on your gut instinct, but that's based on habit, and all your habits are from your old prudish life. Trust me. Just let go!"

She looked over to her son, but she was disappointed to see his legs blocking her view of his penis. (He was still hiding the fact that he already had a full erection.)

Susan looked in Katherine's eyes and asked, "Are you sure about this, Angel?" Without thinking about it, she moved her hands forward and down from Katherine's hips until they were firmly grasping both of her daughter's ass cheeks.

"I am more than sure, because it's something Brother wants. Mom, if you aspire to be one of Brother's very best personal cocksuckers, sometimes you have to be willing to go the extra mile. He is the man of the house now and it's our duty to obey him!"

Katherine was secretly much more delighted than she was letting on. All of Susan's teasing that morning had gotten to her, so she was having to restrain herself to not just hump her pussy wildly on her mother's thigh.

Susan frowned, still wavering. "I don't know..."

Katherine goaded her, "Do it! Just do it, already! That's an order! Besides, just think of that thick meat sliding between your lips. Think of that cum explosion just waiting to pour down your throat!"

They both stood up to make it easier to kiss. It was easy for their lips to meet that way, because Katherine was as tall as her mother.

Susan leaned forward and quickly kissed Katherine on the lips. Since they were both so endowed up top, it was impossible for their lips to meet without their racks pressing together as well. Katherine held her arms tightly around her mother to make sure their front sides were touching all over.

Susan loved the idea of taking orders from her children, and Katherine's bossy ways were hard for her to fight. Plus, the talk of a "cum explosion" got to her - she simply couldn't take any more of that temptation.
