Chapter 2: Upside Down, Again

"Gotcha again." Trisha said with a smile.

Trisha sprung up off the bed and the sisters wrapped each other in a loose embrace. After a series of soft kisses, the two girls smiled warmly as they stared into each other's eyes.

"Oh my God... this is so fucking weird!" Rachel said with a nervous laugh.

"What is?" her sister asked coyly.

"Oh, come on! This whole crazy thing, you and me, this is nuts!" the blonde responded incredulously.

Trisha's smile slowly disappeared. The younger girl then suddenly grabbed her sister's ass as she planted a long, deep kiss on her mouth. After nearly a full minute, she broke the kiss off.

"Rachel, we haven't even scratched the surface yet." Trisha purred seductively.

She allowed a brief pause for effect, before continuing

"I'm going to take a shower. You're welcome to join me, you know, if it's not too weird for you, that is."

The brunette then released her sister's ass from her grip and turned and left the room.

Rachel hesitated for a few brief moments, amazed at how wet her pussy had gotten from just a few words and a single kiss, before hurriedly following Trisha into their parents' bathroom.

They both stepped into the shower and beneath the cascade of steamy water from the overhead tap. Trisha took the soap in her hands and began to build a lather as she eyed Rachel's body subtly. She then turned her sister around and began to gently wash her shoulders.

Rachel sighed as Trisha caressed her shoulders and proceeded down her back, moving her hands in slow, imperfect circles as she went. The blonde then jumped slightly as her sister wrapped her arms around her and softly ran the bar of soap across her flat belly.

Trisha's hands moved with purpose, gentle, yet commanding. They teased Rachel cruelly, sliding just inches from her swollen clit on their lower passes and just beneath the curve of her breasts on the upper. The older girl's excitement was evident in her breathing as Trisha took her sister's hands and placed them against the far wall of the shower, effectively leaning her forward just a little.

She reached around and ever so gently touched the very tips of Rachel's granite nipples with her index fingers. Before long, she was pinching and tugging softly at them, further teasing her sister's senses. The brunette tweaked and flicked the older girl's nipples for a few moments as she drew herself a little closer, letting the hard points of her own breasts graze her sister's smooth back.

Rachel then threw her head back as Trisha suddenly squeezed both her breasts hard, holding them for only a second before releasing them again. She pulled her own body in tight against her sister's as she began to massage her firm tits methodically. The blonde closed her eyes and groaned, pushing hard against the wall in support of her weakening knees as Trisha caressed her breasts with a kind of powerful tenderness.

After a short time, Trisha slowly snaked her right hand down Rachel's tight stomach as her left continued kneading her tits hard. The younger girl brushed her fingertips over her sister's ripe clit once before running her hand down the inside of her thigh, continuing her deliberate tease.

She then spun Rachel around and pushed her roughly against the shower wall as she cupped her throbbing pussy in her palm. The blonde stared at Trisha in breathless desperation, her gray-blue eyes pleading for release. She squealed a moment later as Trisha began to rub her needy cunt furiously.

Rachel's whole body quaked at her sister's skillful touch. The sensation seemed to envelop her entire being, mind, body and soul. She had never imagined that so much pleasure could be derived from the mere touch of another person.

Within a minute Rachel was in the clutches of another maddening orgasm. She held on to her younger sister's slight shoulders for support as her mind clouded over from the impossible pleasure; her ecstatic cries echoing noisily off the tiled walls of the shower.

Almost before her climax had fully run it's course, Trisha gently dropped her panting sister to her knees and leaned her back so that Rachel was holding herself up with her hands on the floor. The brunette then straddled her sister's pretty face, reaching down and gripping the back of her head as she began to grind her sweet cunt onto her mouth rhythmically.

Trisha held one of her perfect tits tightly and stared down at her sister's helpless eyes with a lusty disdain. She continued to pump her narrow hips as Rachel lapped at her hot pussy passionately.

The younger girl rode her sister's face hard for a long while. Rachel ignored the growing soreness in her arms, loving the way Trisha's searing pussy felt as it mashed against her nose and mouth. The brunette finally stopped grinding and issued a muted whimper as she reached her own powerful climax. She reached down and grabbed Rachel's head with her other hand as well as she loosed a surge of juices from her pussy to rival that of the showerhead. Trisha continued to stare down at her pretty sister, her soft, brown eyes blazing with lust, as her orgasm slowly subsided.

She released Rachel's head and helped her to her feet.

"Still think this is crazy... or maybe too weird for you?" she asked with a sly smile.

Rachel gave Trisha a long, deep kiss before answering, with a distinguishable note of wonder in her voice.

"No one has ever made me feel like that before."

"Rachel, Rachel, Rachel..." Trisha began as she stroked her sister's face.

"You have no idea, girl."

The girls kissed lovingly again, before finishing up their shower.

Rachel threw on some clothes to lounge in, a pair of her old boyfriend's lacrosse shorts and a t-shirt and went downstairs to make some lunch. Trisha followed about ten minutes later, just as she was putting the finishing touches on a couple of sandwiches for the two of them.

"None for me thanks." the younger girl said as she passed through the kitchen on her way towards the front door.

"Wait, where are you going?"

"Where am I going? What are you, my girlfriend, now?" Trisha asked mockingly, a broad smile forming on her lips.

Rachel put down her plate.

"Shut up, bitch. I'm just curious." She joked in response, a little embarrassed of her blatant anxiety.

"You know I'm just teasing you." Trisha said as she took her sister's hand and started again for the front door.

"Actually, I think it's kind of sweet."

They stopped at the door and stood close, facing each other. Trisha put on a mock serious face and continued in an exaggerated monotone.

"I am going to the mall with Katie and her mom. We are going to shop for clothes and maybe some makeup, if time allows. And then..."

The brunette broke off laughing as her sister playfully shoved her.

"I hate you!" Rachel laughed as she blushed noticeably.

Trisha then stepped close again and gave Rachel a soft peck on the lips. The older girl didn't see her sister slip her hand into her pants. She pulled away a little and brought her hand up to Rachel's mouth.

"Just to make sure you miss me while I'm gone..."

Trisha slipped the tips of two fingers just into her sister's mouth, before turning and walking out the door with a smile. Rachel shuddered as she tasted a hint Trisha's pussy on her tongue and eyed her sister's beautiful ass as she walked down to her car.

"Holy shit, I think I'm in love." She said aloud, only half joking.

Rachel closed the door, only after Trisha was gone and took her lunch into the living room. She turned on the television and flipped robotically threw the channels as she ate her sandwich. Although she was staring right at the TV's random images, she didn't really see them. The screen in her mind was instead replaying the two shows she and her sister had provided in the last ten hours.

How can this be happening? she wondered silently. The question didn't linger long though. Above all else, Rachel was content. She felt satisfied, though she suspected that was just temporary. She saw the answer to that question, and any others her conscious could dig up, in the pure perfection of their sex. Her feelings were so strong that there was simply no doubt.

The orgasms she'd experienced were nothing short of life changing. And the way Trisha took charge; Rachel had always longed for a lover to do just that. But where her boyfriends had tried, and failed, her younger sister had succeeded. Perfectly. After a short while, the only question that remained unanswered was, How did I not see this sooner?

When her lunch was finished, Rachel lay back on the sofa and settled on a channel, finally realizing that it didn't make a bit of difference what was on. The blonde wore a wide grin as she closed her eyes and soon fell fast asleep.

She napped as soundly as she ever had, for a little over two hours, before she awoke, still wearing that same grin. Rachel pulled herself off the couch and put her lunch plate in the dishwasher, then headed up the stairs to straighten up her room.

She put on music as she dinked around her room, cleaning mainly as a way to kill time before Trisha came home. As she was dusting the pictures on her dresser, one in particular seemed to catch her eye. She took the 5x9 frame in her hands and smiled as she gazed down at the frozen moment.

The picture had been taken about three summers earlier, up at the Cape house. Rachel studied the image fondly, her attention first drawn to the then fourteen-year-old Trisha.

"God she was even hot back then!" she thought aloud.

Her focus eventually shifted to her parents. She had always known that her parents were good looking; it was pretty obvious. Sara had actually done some modeling during a break from college but when she met Dan, decided to ditch the idea and moved so she could be closer to him. But in this moment, Rachel simply saw her parents as two really handsome people, nothing more, nothing less. There was nothing sexual about the realization, at least not overtly, but it wasn't entirely "wholesome" either.

Whatever it was, it didn't seem much to her and after a minute or two she put the frame back in its place and continued her dusting.

She glanced at the clock when she had finished. It was just past seven and she figured (and hoped) Trisha would be home before too long. The blonde then smiled as a sudden idea tickled her. She walked over to her dresser, opened her panty drawer and shuffled through the items until she found what she was looking for.

She slid off her shorts and underwear and stepped into a pair of her sexiest panties, a tiny, pastel pink v-string she bought on her last trip to Victoria's Secret. She then slipped her unassuming shorts back on, deciding her sexiest bra wasn't quite as sexy as no bra at all, and headed back downstairs to wait for Trisha.

After what seemed like days, she finally heard the sound of her sister's car pull up the driveway. Rachel tried to hide her obvious excitement but had to get up to greet her when she heard the front door open.

"Look what I got out of Mrs. Lewis' garage fridge!" Trisha sang as she held up two bottles of champagne.

"Right on!" exclaimed Rachel as she took one bottle in her hand and read the label briefly.

"I figure maybe I can get you drunk and take advantage of you. What do you think?" the younger girl asked with a suggestive smile.

"I think you don't need to get me drunk for that." Rachel answered immediately.

"Oooh, good answer." Trisha responded, before the girls shared a long kiss.

When they finally broke their kiss they walked together into the kitchen. Rachel put one bottle in the refrigerator while Trisha began to peel the foil off the top of the other.

"I have a little surprise for you, big sister." Trisha said a little mysteriously as she struggled with the tightly wrapped foil.

"Oh yeah, well what is it?" the blonde asked excitedly.

"Patience, patience..."

Trisha was cut off by the earsplitting pop of the cork, which ricocheted hard off the cabinets and whizzed by Rachel's ear, missing her by inches. They both jumped at the sound and shrieked laughter as the champagne bubbled over. Trisha brought the bottle to her mouth and took a hearty swig before passing it to Rachel, who did the same.

Once the unruly tide of bubbly had been stemmed, Rachel got some paper towels and wiped up the small puddle, while Trisha walked slowly into the living room. When the floor was relatively clean again, the older girl followed her sister into the other room. Rachel took another belt from the bottle as Trisha offered, before the younger girl placed the champagne on the coffee table and stepped close to her sister again.

"So what's my surpri--?"

Rachel's intended question was interrupted by a sudden, hard kiss. She moaned softly as Trisha's mouth practically assaulted hers. The brunette sucked hard on her sister's lower lip as she took one of the older girl's hands and slowly guided it up the inside of her thigh.
