When the world came back into focus, Andrea had apparently already rinsed and was working shampoo into her hair in much the way Mel had for her. Mel couldn't help groaning her ecstasy. She completely agreed with Andrea's sentiment that this level of pleasure between sisters had to be considered sinful by at least a few religions. She was already considering which way would be the best to return the favor for Andrea's addition to their usual routine.
Andrea was standing in front of Mel as she worked the lather through her sister's hair, all the way to the ends. As she worked, she watched the expressions on Mel's face. First the orgasmic grimace, then the post-orgasmic innocent slack gape and now the thoughtful consideration. She wondered exactly what her sister was thinking and decided it didn't matter. All she cared about was the beauty she was witnessing in its various forms. This only confirmed her opinion that Melissa was one of the world's most beautiful women. She couldn't help just stopping and staring, enchanted.
Mel let Andrea finish shampooing her hair and stood up to rinse when she was done. Pumping a dollop of conditioner into her palm, she waved Andrea back onto the bench, this time with her back to her. She'd seen the vague disappointment in Andrea's eyes, but had managed to keep herself from reacting as if oblivious. Andrea had surprised her, so she was going to surprise her sister right back. If she'd been thinking more clearly like she usually was, she'd have realized Mel wouldn't leave her hanging like that. She must be pretty worked up about Terry and having to wake up alone. Actually, Mel did feel that more often than she liked to admit. Especially after the last week of waking up next to Mona every morning!
Andrea was still feeling disappointed as Mel finished working the conditioner into her hair in their usual sensual way and now it was her turn to play with Mel's hair again for a while. That definitely assuaged most of her negative feelings and she went to work humming happily to herself. As usual, it seemed like she was done in record time and she was disappointed there wasn't any more hair to play with.
Mel got up and directed her under the shower to rinse and as usual massaged her scalp to evenly rinse out the product without washing it away completely. That would've negated the entire reason for using it in the first place. That rinse of course hadn't taken long enough for Mel's conditioner to do its work, so as usual, Mel grabbed Andrea's loofah, loaded it up with body wash and began to sensuously scrub her little sister's body from head to toes. Now she began her revenge. She started in paying special attention to Andrea's most sensitive places, using just the right amount of gentleness and roughness to bring her senses to high alert. Still, she did this quickly and efficiently as if in a hurry without wanting to leave Andrea completely unsatisfied. Then she pulled Andrea under the shower with her to rinse both of them together. This wasn't the usual thing either. They usually both rinsed separately, each watching and enjoying the other as she performed for her. This time though, Mel drew Andrea in and trapped her with a passionate kiss, letting the first of the water flow between them to rinse away Andrea's suds, then pulling her in tight to crush their breasts and press their hips and thighs together. Andrea moaned happily into her mouth as they kissed, wrapping her arms around her big sister and grabbing a double handful of her ass to pull herself even closer. Then Andrea was running her hands through Mel's hair to rinse away the excess oiliness of the conditioning product before they both stepped out from under the fall.
Mel quickly twisted her hair together into a neat coil to wring out most of the water, then wrapped it around her head and secured it with a clip to keep it out of the way so Andrea could return the favor. Meanwhile, Andrea had already loaded her loofah and as soon as Mel was finished, began washing her big sister the way she just had her own body. She started with Mel's back, working her way down from her neck and shoulders, tracing and massaging every curve and highlight. She paid special attention to the small of her back, the perfect globes of her ass and the tight gap between until Mel was panting ecstatically before continuing down her legs, working deeply enough between them to be brushing and stimulating Mel's lips and anus too.
After working her way all the way down to her sister's heels, she turned her around and began working her way back up the front. She could smell Mel's excitement even over the soapy smell of the unscented body wash they usually used. She stared avidly at Mel's hairless snatch as she worked, admiring the silken orchidlike petals just kissed with a touch of the lather from Andrea's downward trip.
When she reached that goal, Andrea attacked her sister's pussy with a vengeance, tracing every single crease and line of Mel's swollen labia, inner and outer. Mel shuddered ecstatically as Andrea circled her sister's clit, spiraling inward until she was circling a path up the nub with her fingertip. She could hear Mel's breathing building to the point where she would lose it and cum all over the place before she quit and began washing her way up Mel's torso. Just keeping the edge on, she thoroughly washed Mel's mound and lower belly, spreading out toward her hips and paying special attention to the inner curves of those hips.
Mel was still panting excitedly as she worked her body over, gently scrubbing over her outer hips and around to her ass again, then up her narrow waist and tummy and onto her ribcage. She conspicuously avoided touching Mel's tits as she washed all the way around them, under her arms and up over her shoulders and down her muscular arms until Mel was practically frantic with pent up excitement. Then she swirled both hands over those glorious mountains of wonder and kept up the swirling spiraling motion, even as she reached Mel's areolas and finally her erect diamond hard nipples. Those nipples were standing at full attention an inch long and obviously highly sensitive as Mel groaned theatrically when Andrea stimulated them. She groaned even more pathetically when Andrea took her hands away.
Andrea didn't leave her hanging though. She immediately reached back down between Mel's thighs and began working her pussy in earnest, dragging her fingertips through the shallow valleys of her labia, up over her clit and back down to sink her fingers deep into Mel's cunt which was practically vibrating with pent up energy. Andrea sank two fingers all the way to her third knuckles into that tight already dripping passage and curled their tips in to touch and swirl just behind Mel's clit, at the soft spongy textured area that was her G-spot, while she stimulated the tip with her thumb. Mel screamed her ecstasy as she exploded and her cum literally washed the soap out of her pussy, splashing up the tight gap between Andrea's hand and her lips, filling it and overflowing it to splatter over both their feet.
Mel couldn't understand how she was still standing as she came down from her orgasmic high. True, Andrea was practically holding her up by her pussy, her fingers still jammed inside her and literally hooked around her pubic bone and crushing her clit. It actually hurt in a wonderful way that had her joyfully aching. Once she had control of her limbs again, she hooked the shaving bench with her foot and dropped onto it, Andrea letting her go, but shifting it and her under the shower's fall to rinse away the soap. Her twisted hair absorbed the water and its weight pulled the clip free causing it all to cascade down her head and neck. She carefully unwound it so it wouldn't tangle and become a knotted mess as she recovered her equilibrium.
Andrea watched her beautiful sister as she recovered from her second orgasm of the morning, once again observing and loving the ecstatic expressions. That was the second most beautiful sight she could imagine after Terry in similar circumstance. Her satisfaction was more than drowning out any trace of her earlier disappointment. She wished they could keep this up all day long, but then she wouldn't get to see Terry later and that wasn't an option at all!
Once Mel had herself straightened out, she got back up on her feet and moved the bench out from under the falling water. Then she grabbed Andrea by her upper arms and turned her around until she was in front of the bench and sat her down. "Somebody's been a very good girl this morning. I think it's time to reward my little sister for her consideration! Andrea, I love you so much!" She dropped to her knees and kissed her sister as passionately as she ever had, their tongues dancing together as their passion built on one another.
Mel could feel her heart flying high as she expressed her love for Andrea in the most direct way she could think of. Her hands cupped Andrea's boobs, completely filling her hands as she allowed her nipples to poke out between her fingers and pinched them sensuously, exactly as she liked her own played with. Then Andrea's hands were returning the favor with interest and their kiss was impossibly deepening. Mel freed one of her hands and let it trail down her sister's body, sensuously tickling, not to distract, but to stimulate. Mona loved it when she did this to her and Andrea was no different, she moaned happily into their kiss and licked Mel's lips in the way she loved so much
