"Amazing isn't it? I hope to build on your present hypersensitivity to another sensual peak. I'll let you open the anti-bacterial soap and shampoo I got in your honor." I watched Lois soak her long hair and face me, her eyes closed. "Your arm movements are making your tits dance irresistibly. Wet nipples taste so good for some reason. Here, feel my tongue rest under your puckering nipples and lap up the water spilling off them. The water tastes as sweet as I expected."
Lois must have expected that assault since she hardly flinched. She poured shampoo on her hair and I took another lick off the other nipple before soap spoiled it. I can't help flashing back to the last time we were gathered. Hearing the word 'tit' would enrage her. Now, she's sharing her tits with me, naked, enjoying my fingers in her pussy ... how surreal!
"As you rub anti-bacterial soap on your beautiful face and body, ride with me while I describe what I do to you. With trust, you can enjoy the exposure, vulnerability, of surrendering your body to me. I'm using a wash cloth with your soap to  rub you lovingly from shoulders, neck, down your chest paying special attention to these shapely boobs and tasty nipples, around your narrow waist with just enough pressure to both clean you and give you goose bumps of pleasure. You sighed loudly. 
"I add more anti-bacterial soap and scrub your curvaceous hips, your silken pubic patch, then surprise you when I bypass your enticing clit and slide down your long legs and over your feet instead. Once nearly all the soap is gone, I nudge your knees far, far apart and wipe straight up your thighs into the leg/hip creases and finally over your mound. Your hands freeze, shocked motionless, still in your soapless hair. Your eyes are closed, but your frozen grin betrays your pleasure.
"Watching you enjoy a simple shower so much, with my hands welcome on your svelte body, makes me glow warmly. My wash cloth is in your pouting pussy, between swelling sets of lips. Once I sadly wipe away your juices from your compelling  canal, I toss the cloth and use my bare fingers to open it wide. I hear your raspy breathing over the sound of the water! Lean back, so I can further explore your sweet pussy. We're both breathless."
About then I noticed our audience. Joe and Sue were quietly enjoying Lois's bliss with me.  They sat naked on the lidded toilet, Sue between Joe's legs, Joe fondly and mindlessly pinching Sue's nipples from behind.
"Moving closer between your legs, my thumbs slide into your lips and stretch your clit. My fingers find their way deep into your throbbing pussy. They slide along your textured walls, gently compressing the granular softness. Your abrupt gulp doesn't escape me. Working my way up, I put some pressure on the clitoral sides, then slide along your internal clitoris shaft. I watch you buckle and grab the walls for support."
"Whaaat are you doing to me?" My hand slid back and latched onto her inner lip. I stretched it gently to each side, then pulled it out just beyond her sensitive outer lip. She moaned again and I heard Sue echo her deep, guttural groan as Joe licked his lips.
"I'll avoid your G spot for now since I don't want to overload you ... YET! Two fingers pump your once again fragrant pussy, slide near then tug your clit. Your knees began to waffle again and I brace you, then move the heat of my tongue against your pussy and clit." As I get back on my knees, I notice and report "Joe has his fingers in Sue's pussy and she's leaning into him, eyes closed." Amazingly, I didn't mind him turning her on.
My warm tongue worked its way deeper into Lois's sweetly flavored pussy. Despite all the tasty water spilled onto my tongue, I savored her luscious nectar. I increased my pumping speed, letting my extended pinky bump her rosebud at each in-stroke. She didn't object to the light anal touch, maybe didn't notice it.  I could see her rosebud stopped tensing. It was almost relaxed. Still pistoning her, I began pulling back her hood and had a clear view of her sweet, soaked little man standing tall.
The same pumping then included her clit GLANS and she completely lost control. Rapidly approaching a peak, she locked her head to one side, breathed fast and raspy. Her lights dimmed as her chest and hopping tits reddened. She screamed. Her tender pussy flooded then exploded copious cunt juices on my ravenous tongue in an uncontrolled release. Still shuddering in her latest screaming orgasm, she collapsed onto me. Feeling so gratified, I held her as she lay still, passed out?  I wondered if the very hot water helped make that happen. Joe and Sue stared with open mouths, amazed that Lois let herself go like that.
Still locked in a blissful embrace, I rocked her gently. We laid there just a few minutes until Lois stirred. She was dizzy, smiled and wondered what happened. I didn't answer just so she'd slowly recall her blissful fall into unconsciousness. Her unfocused eyes stared up at me. She realized where she was and remembered feeling light, high and exquisite (her words). She asked what happened. "You let loose a loud screeching orgasm and passed out."
"No I didn't! I don't do that."
"OK, Thomasina, ask our audience." and I pointed to our mates.
She gulped. "You were here all the time watching? Why didn't I see you?"
"Sweetie, your eyes were closed and your head was floating. Tell her what you saw, guys."
Joe and Sue told her she was thrashing and enjoying my fingers and tongue, then screamed and passed out.
"O h ... m y ... G O D!"
We laughed at her disbelief and thrilled in her orgasm. "We're only about half done with our shower! I need to wash your sweet little ass yet and then you can wash me." Lois stood on shaky legs, clutched the walls as if rock climbing, and awestruck, silently offered me her back. Using the cloth again, I soaped and washed it. She again got goose bumps as I sensuously stroked her lower back.
"Oh no, not again! I don't think I can take another of those ... not so soon anyway."
"Have no fear, I know that and won't bring you that far again, until later. Promise."
She said "I never worried about my heart before, but promise me I WILL feel that again before we leave."
"Well, I don't know. I may have to have my own relief first or I'll explode."
"You tell me what to do and I'll do it. Anything you want!" 
"You're not ready for 'anything'. You still have to move carefully, but I'll give you some suggestions. You've had several vigorous orgasms. Never forget the fact that you are strongly multi orgasmic. As if you could! We can test and raise your limits later, though thankfully my cock will have to get involved for that. I'll be very careful how fast and far to take you and how often you cum. Are you willing to try that later?"
"Well, uh, Yes! I'm  sure I am. That OK with you honey?"
Joe said "I'm not over the last two orgasms yet, but yes I'd love to watch him fuck you silly again and bring on more multiple orgasms. I don't know how much more astonished I can be."
I began wiping Lois's cheeks, cupping them and dragging the cloth through her ass crack. She jerked away. "Just lean forward and let me caress your ass and wash you there. Notice how the washcloth rubs across your sphincter. If you can relax it and feel the nerves react, you'll see that, to start, it has the same pleasant feel as gently rubbing an itch, and then some. When you let it relax, it can be cleaned a little deeper too. Have you ever slipped a finger tip or anything else inside your ass?"
"What do you think? I'd never looked at or touched that muscle until now."
"Yes, I figured that. When you're ready to try another taboo, you let me know and I'll guide you gently. We can even start here, in the shower, so the water can wash away anything that concerns you. Until you say you want to try feeling something enter your anus, I'll just rub it with the cloth and the side of my finger. You can wash me after I help you relax and feel those nerves fire."
"OK, I'm not ready for anything more than that with my anus. Maybe you can guide me in your ass so I can see what happens."
"I can do that too, though I don't think that's your better choice. Relax your rosebud and try to leave it that way while I rub it lightly with the cloth. Less tension, don't clench your cheeks. If you don't have to relieve your bowels, relax the ring muscles then gently bear down as if you were voiding. That's much better. Here's the cloth snaking just inside that muscle. How does that feel?"
"I don't like it so far, but I do have a faint sense of the itching relief."
"Great, so I won't push you. I'm really flattered that you've trusted me so much and I can't say it enough, I'm really proud of you."
"So are we. Astonished and proud too." chimed in Joe and Sue. Lois blushed a little and relaxed some more. The cloth had less resistance.
"I made sure there's no soap on the cloth. If you're like me, you don't want any inside you, but the cloth washes pretty well with all this water. Tell me which feels better - the long drag, or the short shoeshine stroke. I'll do the long one first." Her asshole twitched, but didn't close tightly again. She began to like  the long strokes.
"I'm not sure why, but I'm enjoying all of you looking  in my asshole. It's so naughty! Maybe it's not as filthy as I thought?"
"How does the long stroke feel now?"
"I uhhh, mmm, hate to admit it, but I feel the itch and relief feeling and it is starting to feel really good."
