On her drive home that Tuesday night, Louise did feel some pangs of guilt. The accuser stood at her left shoulder and brought to her remembrance what she had done.
"I've never put my hands on another man's cock before," she lamented to herself. Of course, with Will's cock, that would be "hand" (singular), since even her diminutive hand was wide enough to cover the entire shaft of his penis and verged on hiding the head as well. In fact, when she stroked him, she could use at most three fingers, and usually she used two.
"Oh, but you did," the Accuser reminded her. He meant that filthy man in the Kroger parking lot a few years back. She recoiled at the thought.
"This is NOTHING like that!" she said aloud. "Mark is a very fine, honorable person, in NEED, not some kind of rapist!" She rehearsed the rightness of Mark's cause, and the validity of her ministry to him, and it satisfied her.
"Besides," she retorted to the Accuser, "This was probably a one-time thing anyhow. I mean, Mark went five years without the touch of a woman, so I'm sure that the way I helped him tonight will take care of his needs for quite some time."
However this turned out to be less than prophetic. In fact, the truth was the opposite of her prediction: suddenly Mark seemed to need her all the time! Immediately after the first time, he called her to minister to his needs 4 or 5 times a week, so that they had to carve out little spaces of time in between her part-time job, her gym workouts, and her other chores. It was easy for Mark. Being a professional writer, he could rearrange his schedule on a whim, depending on Millie's temperament, of course. But he had much more liberty. So, basically, when Louise had time to spen that was not earmarked for something else, she and Mark found a place and they replicated their successful experiment from that first Tuesday night. Fortunately, once they got into a sort of routine, it didn't take nearly as long to accomplish as it had the first time. For one thing, they both knew that there would be copious amounts of cum flying about, so he got naked right away, and she stripped down to her panties without any preliminary coaxing. Although they found some creative places to do the experiment, including in her SUV one time, it mostly happened in Mark's bedroom, as it had that first time. This had initially surprised her, because she had assumed that his first enormous cum explosion was attributable to his lengthy time (5 years!) without a woman's touch. But time soon gave lie to that little fiction. Every time she ministered to him, there was a new, magnificent Vesuvial eruption from his cock head. Honestly, the amount of ejaculate material that man's balls produced was, well ... staggering.
It never became boring though. Mark was great, Louise realized, at thinking up interesting little variations for her to try. Early on, he suggested that she stroke with only her right hand, down near the base of his shaft, and see if she could get her mouth to cover the rest. It was like a fun game for her, and the reward was the large and obvious pleasure it brought to her long-time friend. At first, this made her gag, and she was unable to make her lips reach all the way down to the index finger of her right hand. But she was motivated to please Mark, and after several sessions, her gag reflex started to wane significantly. One time, Mark had really switched things around. After she was undressed down to her panties, he suggested that she put one foot on either side of his cock, and try to stroke him with her feet. It was kind of hard to stay balanced on her butt, and she realized that it was also a really great ab workout, having to keep her legs suspended for so long. That experiment succeeded, too (as they all did now), and resulted in cum drizzled all over her pretty married feet.
Eventually, he asked her if she could try using her mouth only to minister to him, no hands. She looked dubious, but it was a fun rule to try and keep. It did make her gag somewhat, but it also produced a very quick and successful end to the experiment. Though she had not thought about it ahead of time, she realized by the tensing of his balls that she was about to conclude another successful ministry, and that there would be no tap on her shoulder this time. Her big, cute brown eyes looked up at Mark, questioning, about a half second before the first big squirt of cum shot down her throat. She saw how happy it was making him, and so she decided not to mind it. After his spurts slowed, and were more or less oozing into her mouth, he pulled his giant heart-shaped cock head out of her mouth and told her to open wide.
"Stick out your tongue," he commanded. She obeyed quickly, and he seemed very happy.
"Okay, you can swallow it now."
Of course Will, the Secret Watcher, was ecstatic about this new development. At least at first. After this, Mark's training of Louise seemed to stagnate a bit. After four weeks almost daily blow jobs, she was getting really expert at it. But finally, there were a few new additions. The first two were Mark's idea. But the third, more exciting development, was actually Louise's idea, which made Will very, very pleased.
Mark's first innovation was fairly simple. Up until now, he had kept his hands to himself while Louise was fellating him. But now, as she knelt on the pillow between his well-toned thighs, he started to reach down and cup both of her lovely breasts at the same time. They were just the right size, 34C, for him to cup nicely in his hands. Louise was, of course, otherwise occupied when Mark first tried this. She almost didn't notice at first. When she did notice, it felt to her like he was trying to weigh them both in his hands, to compare them. He would pick them both up about an inch, bounce them gently on his palms, and then let gravity take them back down, like twin pendulums of antique clocks. Sometimes, he would squish them together. After a few sessions in which he did this, he started to tweak her nipples ever-so-gently, barely brushing them sometimes. It was like his fingertips and her nipples were doing a little dance. She remembered back to the first year of her marriage, when Will had taken it into his head to (with no preceding formalities) give both her nipples, simultaneously, a very hard pinch. She recoiled, rebuked him, and slapped his hand. He never tried that again. But this, this was so much different. To be honest, it made her pussy wet.
Mark's second idea was related, she realized later, to the thing he had started to do where he squished her breasts together. One day, he just said, as if thinking it up on the spot,
"Say ... I wonder how my cock would feel snuggled in between your two lovely breasts?"
She only knew one way to find out. She got up higher on her knees, leaned forward, and took his member between her soft breasts. She squeezed them together, as he earlier had, and then stroked them up and down his long, thick shaft. Apparently, the answer to Mark's question was, "It would feel very good, indeed!" because the experiment came to a hasty and very messy conclusion, with cum running down all over her neck and chin.
After perhaps three more weeks, in which nothing had changed in her ministry routine, a new idea came to Louise. It was just after a successful volcanic eruption from Mark's manly cock, and she was just a bit disappointed that it had happened so soon. But, she wondered.
"Mark ... do you suppose I could make you do it two times back-to-back? I mean, if I started ministering to you again right away?"
Will, watching the live stream on his cell phone in the Men's Room at work, felt his little cuckold heart skip a beat. He certainly was rooting for them both to have a second success immediately after the first.
"I don't know, love. We can certainly try!" was Mark's answer. Louise got back down and went to work, using all of her best ministry techniques. And, while Mark almost immediately got a full erection, he did to appear to be anywhere close to a second eruption.
"Why don't you take a short break, dear?" Mark suggested.
Louise agreed, but her mouth was turned down into a pouting shape.
"Don't be sad, love!" Mark reassured her.
"It's just ... I was so SURE I could please you again!"
Mark's eyes lit up. "D'you know what just might do the trick, love?"
"What?" Louise asked, hopefully.
"Why don't you take your panties off, and come up and sit on the bed here beside me. Just use your right hand on me, while I (begging your permission) use my left hand to explore your womanhood. Would that be okay?"
The new chance for success excited Louise, and she flung her panties across the room and jumped up on the bed beside him. Mark was just SO smart about sex ... I mean, ministry!
Soon, she was one-handing Mark's big beefstick, and he was fingering her very wet pussy. Will had blown his load in the Men's Room stall the moment Mark had moved his hand over. He had to get back to work, and would have to watch the rest later. "Damn the timing," he thought. Louise, for her part, liked the feel of Mark's gently playful fingers touching her labia and circling her clitoris. And, most important of all ... it made the experiment succeed almost right away! Mark had hit upon the secret that would enable him a double eruption. She was elated.
Mark and Louise continued in this manner for about another month, now about three or four times a week, with no new innovations. They circled around the different variations they'd discovered together, and she was quite happy. Mark's mood was good all the time now, and even Millie's sometimes violent mood swings could not perturb him now. She had succeeded in helping her needy friend beyond her wildest dreams. She had made a real difference in the world. She had taken a wrong, and put it right.
***************
Louise wondered about Will, though. The hadn't had sex in something like eight or ten weeks now. It had always been her practice, from the earliest days of their marriage, to let him initiate intimacy. For one thing, she just assumed that that is the way it was supposed to work. For another, she just really didn't get too much out of sex with Will. If the full truth were to be disclosed, it would become apparent that, in fact, nothing Will had ever done with or to Louise had resulted in her having an orgasm. Sure, she had faked an orgasm ever now and again, just because it seemed to make her husband so proud and happy. But a real one? Never.
She figured it must be Will's age that was slowing him down, and making him not need to have sex so often. Although Will was only about 7 years older than Mark, the difference in the frequency with which they need to empty their balls was, she thought, quite stark. Of course, she had no idea that Will was cumming just as often as Mark ... only into his own hand.
After the month of stasis, Will became dissatisfied and irritated with the situation and, frankly, with Mark. He had expected a sort of monotonically increase in the slutiness of Louise, and in the things Mark successfully tried with her. But now, it was all very steady-state. Sure, he still loved tuning in on his computer or smart phone to see his bride sucking Mark's big cock. That was always going to be a turn-on. But he began to suspect that Mark was purposely stalling ... delaying his first vaginal penetration of Louise. So, he invited Mark out to the pub once again. This time, he even told Louise who he was going with. Louise looked visibly shaken by this. Indeed, she was somewhat rattled by this development, because she thought she had hermetically sealed her home life off from her lov ... her ministry life.
"Why Mark," she wondered aloud to Will.
"Well, you've been spending so much time with him, I thought that it is time for me to get to know him a bit better, that's all."
"Well ... you don't suspect him of ... anything, do you?"
