Strange Insertions Ch. 03

It was two days before Madeline was to go to college. Her bags were packed, she'd said goodbye to her friends, and everything was ready to go. She sat on her bed, staring at the old posters of rock stars and actors she'd left hanging, and wondered what would happen next. She was awash with tangled emotions, nervous and excited, and not at all sure she was ready to leave her family and home behind.

Her parents were having a date night and had promised not to be back till late. Her twin sister was downstairs with a friend. Madeline knew this, because she'd heard the door slam, and the stage whispers and giggling that had followed it. Madeline had ignored them, melancholy and worried about moving. There wasn't much left to distract herself with though, just a pile of boxes and an empty room. She was in her pajamas; a comfy pair of flannel pants with donald duck's face on them, and a loose t-shirt.

Still, teenaged girls are always impatient, and after a while though, she got bored. So Madeline headed out into the hall to look at the house she'd grown up in, glancing into the rooms -- her sister's, her parents, the bathroom, familiar places that would never be the same. She made her way down the stairs and headed toward the living room, calling her sister's name.

"Jeannie?"

She was answered by a shuffling sound from the living room, and an awkward giggle.

"Shh!"

"That's my sister, she might come down."

"I don't care." A man's voice said, "Just don't stop..."

"But- mmf." Her sister's protest was lost in a wet gurgle.

Madeline crept up to the corner and peered around it into the living room.

A man she didn't recognize was sitting on the couch. He was about their age, maybe old enough for college, and fairly handsome. His eyes were closed, but that didn't comfort Madeline's pounding heart. He wasn't alone. Jeannine was kneeling in front of him in her soccer uniform: cleated shoes, knee socks, and her sister's tight, athletic backside barely contained by a scandalously cut pair of shorts. It hardly took Madeline a second to realize what they were doing.

The boy's hands curled in her sister's hair as her head bobbed. The only sound was his raspy breathing and the wet noises from her throat. Glunk. Glunk. "Mmmm. Oh god."

Madeline inched forward clutching the doorway with a trembling hand. Jeannine's head was bobbing faster than ever, up and down, up and down. Now and then Madeline could catch a view of the wet, hard shaft her sister was so occupied with, and the long strands of saliva connecting it to her sister's splayed lips.

The boy's lips parted. "Oh christ girl, I'm coming. Oh I'm coming. Eat it. Eat my cum."

"Yes!" Jeannine gasped, breaking her head from his cock. "Spray for me. Drown me. Fill my mouth with your cum!"

With that, Jeannine buried her head back into the stranger's crotch, until her lips pressed to the splayed fly of the jeans, taking the entire length of his male member into her hungry throat. He gasped. "Yes!" And Madeline saw her sister's eyes shoot wide open, and her throat begin to work as she desperately swallowed, milking the pumping cock into her gullet.

An eternity later, the teenaged girl pulled her face from the pulsing cock with a gasp, coughing and chocking on cum. White cream specked her lips and dribbled down her cute chin. Jeannine gasped like a dying fish, as he grabbed her hair with one hand, and with the other pumped his twitching cock, spraying pulse after pulse of white cream into Jeannine's spiky hair and across her high cheek bones and perfect, cherubic face.

Finally the flow stopped and Jeannine giggled, wiping at her eye with a knuckle, and said, in a hoarse voice, "You cum like a firehose. Jeeze. I'm half blind and drowned. You could kill a girl."

Madeline knew she should be leaving, but something held her. She stared, entranced at her twin's cum splattered face, stunned by the abject sluttiness. She watched as Jeannine grabbed a bottle from beside the couch. Liquor. Madeline was sure of it, by the label and the shape of the bottle. She watched her sister take a swig and stumble to her feet.

"I gotta go get cleaned up."

"S'Okay..." Her friend started. "I gotta go anyway."

"What- already – but I thought we were going to hang out." Jeannine stuttered a response. The stranger stared back, and a moment later she shook her head, hair still crusted with cum. "Fine," she said, stonily. "I'll see you." With that she turned away without another word and for one precious second the two sister's eyes met. Madeline jerked back away from the doorway, knowing in her heart that it was already too late. Before anyone could say anything, she scurried a quick retreat back upstairs.

The thud of her heart chased her up the stairs. The image of her sister was stuck in her mind, hurt and anger on her cum splattered face fading with the shock of... recognition.

Madeline closed the door to her empty room behind herself. This time she'd been caught for sure. She knew it.

After she'd calmed down, Madeline resolved not to say anything about what had happened to her sister. She'd tossed and turned for hours, wishing she could sleep and knowing that she couldn't. It was no use. She felt guilty, and totally embarassed. Every time she snuggled into her pillows and started to drift away memories leaped into her mind. Her sister's face glazed with cum, and her eyes, that flicker of recognition before Madeline had been able to pull away. Thank god she hadn't been masturbating. She'd wanted to, but this was bad enough... and now she couldn't. The wetness trapped between her thighs was utterly damning.

Madeline was not a lesbian. She was sure of that. And she did not want to have sex with her sister. That would be incest. She wasn't like that. No, she told herself, it was something else: the thrill of knowing that at any moment she could be caught, the thrill of getting off so close to her own sister, the horrible taboo of it. And now, the thrill of watching, the horribly erotic images burned into her retinas and the rush of warmth it brought to her cunt. Madeline tossed and turned, pulling the pillow over her head. Best not to say anything, she thought, best to avoid Jeannie. In two days she'd be leaving for college, and then they could forget about the entire thing.

A gentle knocking at her door told Madeline that she'd been sleeping. She sat up with a start, rubbing at her eyes. The room was dark, and she scrambled for her cellphone to check the time. The glowing screen told her only an hour had passed since she'd left her sister downstairs. An hour that had felt like an eternity.

The door opened a crack, and a face peeked in, backlit from the hall.

"Maddie?"

The door opened a bit more, and the light widened. Jeannine was sillhoutted there in loose jogging pants and a sports bra. Jeannine couldn't make out the face, but she recognized the tight curves of her twin's figure.

"Hey Maddie?"

"Mmm, yeah?"

"Can I come in?"

"Uh. Okay."

Madeline pulled the sheet up a bit closer and reached to snap on the lamp. Her sister froze in mid step, halfway into the room, blinded by the light. She didn't have any makeup on, so she must have washed up, but her eyes were swollen and red like she'd been crying.

"Ouch that's too bright."

"Are you drunk Jeannie?"

Her tone was immediately defensive. "No. A little." She sighed, and said sullenly "does it matter?"

"Nawh, come sit down."

Madeline shifted over in the bed to make room for her sister.

"What's wrong?"

"Nuthin. My boyfriend's a jerk, that's all."

"Yeah? What'd he do?"

Madeline hoped she could sound confused, desperately hoped to hide what she'd seen, that somehow Jeannine wouldn't know, or that at least they could pretend. No such luck. Jeannine looked her right in the eyes and said "You saw. He left me right after... right after he came."

Madeline swallowed. Her sister's eyes were bloodshot, but as bright green as ever. A quaver at the corner of her lip said she might cry again.

Jeannine took a deep breath and said, "He used me."

Madeline sighed tensly. "Men are jerks."

Jeannine only nodded, so Madeline leaned over and put an arm around her. "Hey sis. It's okay."

Jeannine rested her hand on her twin sister's shoulder, and they enjoyed each other's warmth for a few minutes. Madeline hugged her gently, sure that her sister was about to cry, waiting for it, but mostly overcome with relief that they'd dodged an awkward coversation about why she was lurking on the stairs spying on her naughty sister. Slowly Jeannine's trembling stopped, and Madeline washed with relief.

Then the sucker punch. "Hey Maddy?"

Jeannine had her hand on her sister's thigh, just above the hem of her nightgown. She was caressing the skin there gently, seemingly unconsciously, and no amount of careful squirming was getting Madeline away from it. She swallowed, and answered quietly, "yeah?"

"I kind of liked that you were watching."

Heart attack. The conversation she was hoping to avoid blindsided Madeline. Her mouth instantly went dry, and she knew that the filmy material of her nightgown couldn't contain her pounding heart any better than it hid her suddenly stiffening nipples. "Jeannie-I-I-" The touch on her thigh wasn't so innocent anymore. The fingers slipped higher, and higher, until they were seconds away from the soft down of her pubis. The touch was gentle, lingering, and good. She wanted more.

Instead, Madeline jerked back before her sister could go further, pulling away from the touch and the conversation. Instantly she regretted it. Color rose to Jeannine's face in a flood, and her mouth dropped, the humiliation clear from her quivering chin to her eyes. She'd crossed a line, and her sister had rejected her.

"I'm sorry Maddy."

"No Jeannie I-."

"I just thought... that you were watching cause you liked me. I saw you in the kitchen, and I thought you knew. I thought you liked that I saw, you were all... flirty. I was flirting."

"I-"

"I'm so sorry." Fat tears were running down Jeannines cheeks now, and Madeline was at a loss.

"It's not that. It's not- I mean, you're my sister!"

"I know! I'm such a slut!" Jeannine's cry was a wail, and Madeline was deathly afraid would waken their parents. She half considered flinging a pillow over her sister's face to stifle the incriminating cries, and desperately searched her mind for something, anything to say to make things better, any comfort she could provide. Before she could do anything to respond Jeannine had fled the room, and the door to her room slammed down the hall, leaving Madeline alone and very confused.

-----------------

Madeline spent the next day avoiding her family. The entire thing was too embarassing for words, and she didn't know how to fix it. She was due to leave for college the next morning anyway, and had the fuzzy notion that she'd just wait, and avoid the subject until there was some distance between her sister and herself. The plan stuck for most of the day.

At supper time, her mom caught her in the hallway on the way to the bathroom. Jeannine was behind her, wearing her soccer uniform again, knee high socks, those tight little shorts and a loose jersey. She wouldn't meet Madeline's eyes, she just looked down like a beaten dog.

"Hey honey." Mrs Engels called, "I'm dropping your sister off at soccer practice and your dad and I were going to get burgers, you want to come?"

Madeline couldn't look at her sister, so she looked up at her mom instead. "I dunno mom, I'm feeling sick." She shuffled her feet. "And I've got a lot of packing to do."

"Well that's too bad, we'd love to have you, wouldn't we Jeannine?"

Jeannine made a noise somewhere between a grunt and a gurgle.

"Are you okay? You're not feeling sick too, are you?"

Jeannine winced. "No mom... I'm fine. I'm just gonna wait in the car." She stole a quick look at her sister and slunk off.

Madeline swallowed. It was worse than she'd thought. She wanted to chase after her, but didn't know what to say, so she hugged her mom tightly instead. "Have fun mom. I'll be here when you get back," and ran to her room, without waiting for a response. Out of nowhere, she had a plan, she didn't know if it would work, but she knew she had to do something. She just thanked god she'd thought of something.

There was a vent that seperated the twins' bedrooms. It was old and had wide gaps in the grill, easily an inch between each. As kids they'd played spies, whispering through the vent and passing secret notes. They'd pretended to be in prison, sneaking daddy's files through the bars, and lay at night with their faces to the grill gossiping into the night. Through that vent they could say anything they want, whenever they wanted, and see right into each other's rooms. It was perfect. Then puberty came and modesty followed it. Madeline had tacked a cut out from one of her magazines over the grill, and the secret spy hole had been hidden.

Now Madeline's hands trembled as she pulled the tacks out one by one and revealed the grill behind the old magazine pages. She knew she'd be able to see into her sister's room with ease if the lighting was reversed. All that was left was to wait. When Madeline finally heard the crunch of gravel on the driveway she hurried to turn out the light, heart stuck in her throat. Her wait wasn't over. She listened to the footsteps and voices downstairs and the chatter of her parents until finally she heard the sound she'd been waiting for, the thump of her sister's soccer shoes on the stairs. Madeline lay down on the floor to watch the vent.

The door creaked and Jeannine's light flicked on. Through the vent, Madeline could see everything. Her sister's hair was plastered to her head with sweat, and she was still flushed and gleaming from the exertion of her game. Madeline's heart sweet swelled with love for her sister, and sunk again with guilt. The plan had to work. On the other side of the vent, Jeannine stretched, kicked the door shut and wandered over to the cd player, popping in the latest Miley Cyrus album. She stretched again, and proceeded to strip off her mud splattered jersey and shorts, swaying to the beat of the music. Madeline's breath was tight in her throat as she watched. Jeannine tossed the jersey on the bed and popped the clasp on her sport's bra, letting her perky, apple sized breasts with their perfect dimpled nipples bounce free. Totally unaware that she was being watched she stripped off her shorts, ran a hand across her smoothly shaved twat and scratched casually at her tight, athletic ass. Then, clearly exhausted, she strutted back to the cd player, turned off the music, and bounced across the room to turn out the lights. The room filled with darkness.

Madeline could hear the shuffle of bed clothes and knew that her sister was climbing into bed. Now timing was key. She forced herself to count to twenty before getting up and stripping off her own clothes. She very nearly shook too much to find the lightswitch, but she knew that she was comitted. Light flooded the room.

Lying in the dark, Jeannine couldn't help but see the light come on through the vent. She'd see it, and know that her sister had moved the poster and opened the vent. It would be an invitation too good to pass up, and she'd have to crawl across the carpet and peek through the cracks into her twin sister's bedroom. Madeline was counting on it.

Madeline was back on the floor, naked as the day she was born. She had a pillow propped under her ass and one of her legs wrapped around the foot of the bed. The pose forced her thighs comfortably apart, giving a perfect view from the peephole, and open access to her wandering fingers.

She started with two fingers. She was already so wet that it wasn't a problem. Her legs trembled with the effort of staying apart as she fucked herself, but she had to keep them wide to give her sister the best show she could. Soon two wasn't enough, and added a third finger into her clasping tunnel, thrusting urgently against her hand. Her toes curled, and her heaving, pink tipped breasts shook with each thrust.

"Oh god, oh god," She moaned, fucking herself relentlessly. The juices ran down the crack of her ass. She pulled her hand free, licking each finger in turn, searching the vent with her eyes as she did, hoping to see some movement, some tell tale sign in the darkness behind. It was impossible to know if she was being watched, and that made the the horny young woman even crazier. She took all three fingers in her mouth, sucking and slathering at her hand until every trace of her own teenage arousal was gone from them.

There might have been a sound from the vent, she couldn't tell. She imagined her sister lying there naked, breasts pressed to the carpet, eyes wide, face to the grill. Maybe Jeannine was fingering herself, maybe she'd reached back between those tight thighs and was building her own orgasm. The thought drove on her on to deeper perversity. Madeline rolled over onto her stomach, thrusting her ass into the air and back toward the vent. Reaching back she pulled one cheek to the side, exposing her juicy, swollen box and the tight star of her virgin asshole. The thought of her sister seeing her so exposed was utterly humiliating, and almost made her cum on the spot. She wiggled her backside, touching her juicy slot with the tips of her well manicured hands.

There was a bottle lying under her bed, an old-fashioned coke bottle that she'd brought back from a vacation years ago. Madeline had seen it while she was fucking herself, and now she dug it out. It was too big for her to take, she was sure of it, bigger even than the cucumber she'd stretched herself with. She had to try it though, she desperately wanted to be filled, and she only had one night with her sister, one chance to make ammends or one last chance to use the her twin for her own pleasure, she wasn't sure which anymore.

The glass was cold, but the tip of the bottle fit easily into her swollen pussy. An inch of shaft followed, then two, splitting her lips and forcing a moan from her lips, but soon the bulge of the coke bottle was too fat. The angle was no good anyway, so Madeline sat up, planting the bottle on the floor and holding the base still with one hand.

She couldn't look at the vent, not while doing this, it was too much humiliation to bear. So she turned her back to the vent, exposing her naked profile and the twin curves of her ass as she squatted over the bottle. Very carefully she lowered herself, and for the second time that night gingerly penetrated herself again with the tip of the bottle. Gradually, inch by inch, she let herself sink down onto the bottle, sure all the while that it would never fit, that it would tear her tight cunt apart before it got in.

"Ooooooooh" she moaned, sinking deeper. Madeline was stretched her nearly to the breaking point. Her whole, quivering teenaged body was wracked with a sweet pain that made her want to scream and thrash and both throw the bottle away and fuck it harder all at once. Her pussy lips were wider than they'd ever been, peeled obscenely apart. They clung to the bottle and grasped at it every time she pulled it out, and eagerly swallowed it up with each thrust back inside.

Madeline's cunt throbbed as the ribbed glass plunged her depths, but she couldn't get more than a few precious inches, it was too tight, too big. Her knees shook and ached from squatting, and no matter how much she rose and fell on the bottle it wouldn't go deeper. Then she heard a cough from behind the grate - she was sure of it this time - and the sureness that her twin was watching was all the help she needed. With a thrust of her hips, Madeline forced herself down on the bottle, and it popped in past the first bulge, filling her once tight teenaged pussy to the brim.
