Chapter 12

“Come on in,” Diana grinned.

Maddi didn’t bother knocking. Her desperate eyes laid on Diana snickering from the sofa, wearing a silk blue bathrobe sheer enough to see the full contours of her breasts. The main area was lived-in and straightforward. Flanked by a pair of wobbly end tables, the deep-seated sofa sat behind a cheap glass coffee table. The room’s light was dim; Maddi would have found it romantic under normal circumstances. But her stomach dropped once she saw Mary looming in the bedroom’s doorway.

Mary’s body was sparse and skeletal. Maddi couldn’t remember if the girl’s skin sagged so much the last time she thrust over her. But what monopolized Maddi’s attention was the black harness that hung loosely around Mary’s bony hips--it boasted a long, girthy strapon made of rugged, bright yellow plastic. Maddi’s insides twitched with fear.

“Hey, Maddi,” Mary cooed with stirring anger behind her dead blue eyes. “I’m surprised you showed up. You’re such a coward.”

“Hi, Mary.” Maddi slipped from her flats. She shivered when her feet kissed the cold floor. “Let’s just get this over with,” With a committed sigh, she fumbled with the loose school uniform before pulling it over her head.

“Oh!” Diana raised her hand. “Can I make one request? Please keep your sweater on.”

Maddi rolled her sweater back on. “Why?” She asked.

“I don’t need to see your tits, Maddi.” Diana scowled. “I am your sister, after all.”

“It’s just like her. She wants to turn you on.” Mary teased. She lunged at her quarry and forced her hand up Maddi’s sweater. She quickly found and twisted at one of Maddi’s tender pink tips. As Maddi winced, Mary felt a tinge of perverse excitement. She blushed. “You’re such a fucking slut you’re not even wearing a bra. I can’t believe I loved you. Take off your skirt, now.” Mary commanded.

“Fine,” Maddi shivered as she fumbled with her uniform skirt. As she stepped out of her panties, she caught the sight of Diana’s backside as she strode to the bedroom. “Di--where are you going?”

“I’m going to shower and give you girls some privacy. I won’t need this,” Diana giggled. “I’m just going to play some music on my phone. See y’all in a bit!”

The sight of Diana’s nude backside and the tender jiggle of her luscious globes, as she strolled, stole Maddi’s breath. Without realizing it, she gawked as her sister disappeared into the adjoining bedroom. The shower’s sudden roar clashed with the noise of electronic dance music on Diana’s phone, creating an unsettling cacophony. Maddi felt the blood surge through her body. She fidgeted to tuck her cock between her legs--as it pulsed and threatened to come alive.

“Follow her,” Mary said as she jabbed her angular fist into Maddi’s spine. “The only bathroom is attached to our bedroom,”

“That must be convenient in the morning,” Maddi mused, taking a moment to survey the modest yet cozy apartment. A modern kitchen boasting chrome-plated appliances was attached to the open living area that occupied most of the building. Past the kitchen, there was a beautiful patio with a stunning view of the lush Moringa forests. ‘If Mary only knew how many times Diana filled me up in those woods,’ Maddi thought as she shivered. ‘I’m gross,”

“Just move,” Mary growled. “I’m going to fuck your ass,”

“I know. And then we’re even?” Maddi turned back. “Do you have lube?”

Mary scoffed. She tossed her brittle ginger hair behind her shoulder as she smirked. “Looks like you’ll have to grin and bear it--while you’re baring it, slut!”

“Hold on,” Maddi dashed back to her discarded skirt and searched the pockets. She grabbed a small clear bottle from the pile and rushed it into Mary’s arms. They barely made eye contact while Maddi hurried through the door to hop on the bed. She hiked her robe over her narrow hips and buried her face in the brown satin bed top comforter.

Maddi tensed as Mary’s petite footsteps inched closer, only sighed with relief when she heard the lube bottle’s plastic cap snap open. At the very least, Maddi had some reassurance that Mary would use some care. She winced when the cold gel slithered down her crack.

Mary used her strapon’s tip to apply the lube generously. “You ready?” She afforded her ex-girlfriend some pleasantry.

Maddi sucked in a final breath before nodding. Then, her entire body contracted. She grabbed at the blankets, pillows, and anything she could get her desperate hands on as her asshole filled with hard plastic. She screamed into the bedding as Mary rammed.

The bedsprings screeched as Mary pumped. Maddi felt Mary’s full strength and weight on her back--which gradually grew underwhelming. If not for the pressure in her ass, Maddi might have found the contact enjoyable. Mary’s thrusting varied speed and force as her endurance waned.

Maddi grunted under the force. It surprised her how painful the situation had become. Then, her eyes caught Diana’s movements as she emerged from the shower.

Still nude with freshly washed, supple skin, Diana circled the bed, silently positioning herself in Maddi’s vision. She fiddled with her phone to stop the music. Then she rubbed at her eye near her chubby cheeks, encouraging Maddi to cry.

“Take it, you slut!” Mary cried, her slender hips buckled around her harness. She shoved the strapon deeper into Maddi’s guts with awkward thrusts. “Does this hurt?” Her voice cracked, on the verge of tears. “Am I hurting you?”

“Yes,” Maddi cried. She forced the submissive words from her throat. “Yes, please stop hurting me!” Her plea came out in humiliating grunts. “STOP!” She wept. Maddi yelped as Mary drilled her one final time with a shock that jarred her.

“I--I’m hurting you?” Mary sounded shocked. She grinned with satisfaction. “Okay, then. I’ll stop, you big wimp.” She turned to undo her harness. “How does it feel to have someone deflower you?”

“She’ll be sore tomorrow,” Diana commented. “Hope you weren’t saving that ass for something special, Mads,”

Thankful that Mary finally withdrew from her aching ass, Maddi could only afford herself a small gasp of breath as her dominant wrenched her around.

Mary grabbed Maddi by the jaw and pried it open. “Taste yourself, Maddi. Don’t you taste like a slut?” Mary licked her lips as rabid saliva drooled from her mouth. Her nails dug into Maddi’s scalp as her hips bucked forward. Mary face-fucked Maddi with a light yet not-so-gentle rhythm until her victim’s head knocked against the wall. She tightened her grip as Maddi squirmed. “Stop struggling, Maddi,” She commanded over the sounds of Maddi’s gagging.

Finally, Maddi found no need for dramatics; She couldn’t breathe. As the musky taste of her asshole invaded her throat, Maddi wretched. It worsened her plight. Her body tensed as she fought against Mary’s force. The girl’s face reddened--then the coarse color bled into her eyes. As the pressure built inside her withered lungs, Maddi’s weakly hammered against Mary’s breasts. What scared her more than anything was she could tell how hard Mary’s nipples grew--as her vision blurred, Maddi wondered just how aroused Mary was getting over hurting her.

“Oh, God...” Mary’s voice quaked with excitement as she watched her victim turn blue. “Oh, my Lord, I could kill this whore right now,” She uttered. Under the realization, Mary’s frail legs buckled under the weight of her lewd climax. Her hand stayed fast under the harness. Mary slowly freed her palm as she silently gawked at the damage she had inflicted. Next followed a subtle drip of her shameful honey across her wrist. Mary let a gasp escape her agape mouth as she recoiled in horror. She examined the fluid that webbed between her fingers. “I-I didn’t mean to,” Her words stammered together. She trembled. “I’m not like this. At least, I didn’t think I was.”

“Oh!” Diana cooed. She rubbed herself against the bedroom doorway as she leered over the scene. “Mary, did you seriously just get off by hurting my sister?” She couldn’t contain her excitement as she glided along the wall and grabbed Mary by her waist. “That’s pretty hot,” Diana guided Mary’s soaked fingers to her lips. She moaned her pleasure as two digits passed her lips. “Mmm...” Diana shivered.

Maddi gasped for air as she tried to understand the madness. She knew what she had with Diana was too good to be true. She glanced at Diana’s sheepish grin as her sister started stroking herself slowly.

Mary calmed down and sighed. “You’re right, honey. That was hot. I don’t have anything to be ashamed of because God’s using us to punish this awful person. I want to show her what we do.” Mary cooed before her harshness returned. “Now lay back on the bed, Maddi,” she commanded.

The blood rushed to Maddi’s head as she reclined reluctantly. She heard Mary’s strapon and harness unsnap and clang to the floor--seconds before Mary’s bare bottom loomed over her. “MMPHH!” Maddi grimaced. Her hands flailed as Mary humped her face.

After some sloppy attempts to find Maddi’s mouth, Mary, at last, settled her slit over her ex’s tongue. “Eat it!” She cried. “Eat my pussy!” Mary bounced awkwardly, occasionally stopping to ensure she smeared her wetness over most of Mary’s face.

“Language, dear Mary!” Diana cried with laughter. “But it’s kinda hot to see you so aggressive,”

“I’m so glad I plugged myself,” Mary leaned over to grip the headboard as she flexed her pelvic muscles. “She left so much!” Mary’s voice strained as she pushed.

Maddi squirmed as Mary sputtered a creampie into her mouth. Much to her relief, Mary’s body had kept Diana’s cum nice and warm. There’s nothing I hate more than cold cum, she thought. But Maddi’s body reacted terribly as the creamy saltiness assaulted her tastebuds. Her heart pounded once she recognized the taste of Diana’s cum--or at least she swore she did. Her hips bucked as her cock straightened. Tasting her sister’s spunk was the comfort food she needed--the familiar disgusting indulgence to calm her nerves after such an unpleasant day.

“Mmm!! NGH!!!” Maddi stopped flailing. Her hands went to her cock to stroke herself. The efforts wouldn’t take long to reach a payoff--she could feel her cum rising in her pulsing shaft the second she squeezed her cock. She slathered her tongue deep into Mary’s pussy, licking, eating anything she could coax out. Her hips spasmed in mid-lick. Cum exploded, lashing across Mary’s back until it bubbled and the spurting subsided, leaving a fresh pool on her concave stomach.

As Maddi thrashed, Mary nearly topped. She slid off Maddi just as the futa’s draining cock smeared against her back. Mary’s contemptSheful glare ran across Maddi’s blushed nudity; her cock rested atop her writhed form, pulsing some cum that flooded her navel.

“Y-you came?” Mary scowled with disbelief. She read the embarrassment on Maddi’s face as the girl shamefully licked her lips. “Stop,” Her voice quivered as she disgested the sickening truth. “You weren’t supposed to like that, Maddi. Eating your own sister’s cum.” Mary wretched.” You’re disgusting,”

Diana sighed as she sat on the bed’s corner. “In all fairness, Mary,” She dipped her fingers in Maddi’s cum. “You knew Maddi’s body would react this way,”

“You’re defending her?!?” Mary cried in a panic. Her chest heaved, hyperventilating.

“I’m merely saying you shouldn’t act surprised.” Diana sat down to caress Mary’s bony shoulder. “I mean, I have all these stretch marks and a baby in private custody. That’s evidence to suggest she’s attracted to me, even if she’s a repulsive cretin,”
