The Roommate Pt. 40

XL: Can You Trust Me?

Marie

Marie returned to her room to find it dim, the only light that of the evening sky, streetlights, and Lexi's phone illuminating her gorgeous face.

Only halfway into the room, Marie took a moment to drink in the girl, admiring her. She had a strong jaw, yet soft, sensual features, incredible muscles, yet curves and a figure Marie envied. Even with the windows shaded, the unorthodox lighting only emphasized that.

When Marie looked back to Lexi's face, she found the tall girl smirking at her and blushed. Lexi drew the large plug out from under the covers with one hand, then beckoned Marie to her with the other.

"Are you ready to have this big fat plug stretch out your ass for me, now that you're all nice and clean, slut?"

Marie swallowed, pussy twitching, "Yes, Lexi. Please."

Lexi rose from where she'd been reclining and set the plug on Marie's nightstand, laughing in a way that made Marie shiver.

"Such an eager little slut. I'd like to just give you what you want, but I wouldn't be doing a good job if I didn't make sure that you're properly warmed up, first."

She pointed to the now-empty bed, "On your hands and knees at the edge of the bed."

Marie shivered and complied, arching her back and wiggling her ass just a bit, hoping it would entice Lexi to even just skip the plug and fuck her.

She shuddered when Lexi took her ass in both hands, squeezing gently, then gasped when Lexi smacked both cheeks. The sharp, slight pain going straight to her pussy. Then Lexi's mouth was on her ass.

Marie shivered, letting out a moan at the image the sensation conjured in her mind. Lexi kissed, then sucked on her right ass cheek before biting down just enough to reach the border of pain and pleasure, then let go, the room's cool air making the spot outlined by her saliva cold enough for a few shivers.

When Lexi ran her tongue across Marie's lower lips, Marie nearly fell forward onto the bed. Lexi had teased her the whole fucking day. Finally having Lexi's tongue--any part of her--between her legs felt incredible.

"Fuck," Marie breathed, "Oh fuck, yes."

Marie felt Lexi's grin against her lower lips, "Enjoy it, slut. Just as long as you know your place." A moan slipped from Marie's lips when Lexi grabbed both cheeks hard. That, combined with Lexi's tongue working its magic on her pussy made Marie slump onto the bed. Her heart pounded, breath coming in heavy, increasingly ragged breaths.

At some point, an errant through bubbled up through the webs of pleasure running through Marie's body.

"Aren't--" she had to take a breath and think for a moment to get the correct words to come out, "Shouldn't I be the one doing this?"

"Going down on me?"

"Mhm" was all Marie could utter in response as Lexi stuck her tongue deep between Marie's folds.

"You'll get your turn," Lexi said, speaking between licks and kisses, "I happen to like the taste of pussy. And this is good training for you, slut."

Marie gripped the sheets as Lexi's chin ground against her clit.

"If you're going to be a good slut, you'll need to learn how to function even if you're nearly overwhelmed by pleasure."

Marie's stomach fluttered as Lexi ran her nails down the backs of her thighs, tracing her lower lips with the tip of her tongue.

"Well, you'll need to function enough to pleasure me, at least."

She thrust her tongue deep again, forcing a moan up from Marie's throat.

"Plus, I think you would agree that I can be just as in control of you giving oral as I am receiving. Am I right?"

"Mhm."

"What was that, slut?"

Marie had to take a deep breath to find the words, "Yes, Lexi."

She gasped as Lexi's tongue left her pussy, then moaned at the hard smack on her ass. Her brain was so fogged over with pleasure that the actual pain only lasted for a moment, the warmth morphing almost immediately into just another flavor of pleasure.

"Yes, what, slut?"

Marie squeezed her eyes shut, pussy clenching and sending sparks of arousal tingling over her skin.

"Yes, you can control me even when you're eating me out. Just feeling your tongue on my lips made me collapse, because I'm your slut."

For a moment, Marie worried she hadn't said the right thing, as silence filled the room save for her labored breathing. Then Lexi's fingers dug into her ass cheeks and the flat of her tongue pressed against Marie's clit, the bridge of her nose parting her folds. Marie shuddered as Lexi gave her a pussy a firm, slow lick, then gasped as Lexi reached the end of her pussy and kept going and pressed her tongue against Marie's puckered hole.

Marie suddenly found herself far closer to the edge than she'd been all day. She gripped the sheets tight, breathing shallow as Lexi pressed her tongue hard enough to slip past the tight ring of muscles and start tongue-fucking her ass.

"Oh, fuck," Marie gasped, "Lexi, please! I--"

Marie whimpered as Lexi withdrew.

"You what, slut? Are you ready for me to finally fuck you ass?"

"Fuck, yes," Marie moaned.

"Hmm," Lexi said, "Stay there."

Marie did as she was told, then gasped when something soft, but firm pressed against her asshole.

"Are you ready, slut?"

"Please."

Lexi cackled, and Marie moaned as the cockhead pushed past her opening and stretched her tight hole.

Fuck, am I really that tight?

Lexi felt fucking huge. Like she was getting bigger with every--

Marie's eyes went wide as a the cock swelled suddenly into a bulb, stretching her ass wide before she swallowed it and felt deliciously, yet almost uncomfortably full.

"Thought--thought that was your cock," Marie breathed, suddenly out of breath.

"I know you did," Lexi cackled, "But you haven't earned that just yet."

Marie whimpered, "But--"

Then she remembered herself. She took a deep breath to try and straighten out her thoughts, "How can I earn it?"

"Earn what?" Lexi asked.

Marie almost whimpered again, "How can I earn your big fucking cock fucking my ass?"

Lexi cackled from behind her, and Marie gasped when the girl's fingers dug into her ass cheeks.

"You know exactly how. You need to be a good little slut while I enjoy myself."

"How--fuck!"

Marie gasped as Lexi's tongue parted her dripping folds, sending shocks of pleasure through her that made her legs quiver.

"I want to make sure you know," Lexi said, pulling back from Marie's pussy just enough to speak unmuffled, "That giving someone oral isn't purely submissive."

She licked Marie's folds again, pushing her tongue deeper this time. Something pushed the base of the giant plug as well, re-alerting Marie's body to its presence.

Fuck, that thing is huge.

Marie found herself glad Lexi's cock wasn't that big. She didn't think she could take it if Lexi fucked her as hard as they both wanted.

She would break me.

Marie shivered at the thought, then blushed as she realized how hot she found that idea.

Lexi sucked on her lips, filling Marie's mind with a wonderful haze.

"I may be on my knees with my head between your legs," Lexi said, voice like honey, "But you're the one melting into a puddle."

She licked Marie again, slow and firm, then laughed, "Mmm. Seems you're trying to take me literally. Good slut."

Marie drew in a deep breath as her heat pounded a bit faster. It wasn't fair that those two simple words had such an effect on her. She lost herself in Lexi's attentions, sinking into the bed, legs barely keeping her upright as Lexi blew her mind. The combined sensations of the massive plug stretching her ass, and Lexi's mouth between her legs, always teasing, never quite trying to get her off, but just playing with her, brought her so high, yet still nowhere close to the edge.

Is she enjoying my pussy, or enjoying fucking with me?

Marie didn't really think she cared. It felt so fucking good, either way.

Fuck. Why can't she do this and fuck me in the ass at the same time?

Marie was so lost in Lexi's attentions that she gasped when the girl finally pulled away.

"Mmm," Lexi purred from behind her, "You taste really fucking good, slut."

Marie gasped, then moaned as Lexi's fingers ghosted over her back, sending shivers through her as goosebumps rose all over her body.

Lexi giggled, "Did you enjoy that, slut?"

It took a moment for Marie to form a response. Her voice was raw and breathy when she spoke, "Yes, Lexi."

She could feel Lexi's smirk, "And did you feel in control when I was going down on you?"

"No."

"Then who was in control?"

"You were, Lexi."

"Good. Off the bed. On your knees, between my legs."

Despite the fog still clouding her head, Marie didn't need any extra time to follow Lexi's order. Something in the way her voice changed so effortlessly from a satisfied purr to a confident command simply made Marie move, doing what Lexi told her almost without thinking. The movement made her almost uncomfortably aware of the thick plug stretching her ass. In moments, she found herself on her knees, gazing up at Lexi, head foggy from the stimulation in her ass and the lasting effects of Lexi's mouth. Not to mention Lexi's thick, gorgeous cock standing out just inches from her face.

Marie looked beyond the incredible cock to its owner, however, and whimpered as her pussy and ass clenched in response.

Lexi was just so gorgeous. Her muscles made Marie's mouth water even as they made her feel safe, and a little bit in awe. Her curves were just as incredible, and the way they blended with her muscles to create the succubus before her was just unfair.

"Slut?"

Marie blinked, then blushed and looking down.

"Sorry, Lexi. I was...distracted."

A single finger under her chin made her shiver, and Marie let Lexi lift her chin. Marie lifted her gaze as well, meeting Lexi's. A wave of relief washed over her when she found amusement in them rather than disappointment. Lexi's face was so close to hers. Marie found her eyes soon focusing on the girl's lips, and her pussy clenched when she realized they were still shiny with her juices.

Fuck, I want to taste that.

"I guess I should take it as a compliment that just looking at me can distract you enough to completely override whatever I'm saying," Lexi said.

Marie snapped her gaze back to Lexi's eyes, unsuccessfully trying not to blush.

Lexi grinned, "But a good slut pays attention to her domme, got it, slut?"

Marie nodded, "Yes, Lexi. Sorry."

Lexi leaned forward and kissed her.

Marie couldn't help the moan that rose up from her throat as she returned the kiss. Tasting herself on Lexi made her heart race. Her blood felt live lava, running through her. She needed more that just the kiss.

Lexi seemed to sense that, however, as she pulled back just before Marie reached up to hold her. When Marie's eyes fluttered open, however, she found Lexi's cock had replaced the girls lips as the focus of her vision.

"We're going to work on trust before you get your reward, slut," Lexi said, "You've been doing very good, but I need to get my cock all nice and wet before I fuck your ass, even with that big plug stretching you out in preparation. I also want you too horny to think straight."

Marie whimpered at that, holes clenching to send shivers through her body.

Lexi grinned and stepped closer, letting her cock rest on Marie's face.

Marie had to take a deep breath to keep from shuddering. It was so warm, so fucking hard.

"You're going to take this down your throat," Lexi said, "But instead of letting you control that, I'm going to be in control. There will be times where I want you to work that magic little throat of yours on my cock and make me explode. Tonight, however, I want to fuck your throat. Specifically, I want to shove my cock as deep as I can and hold it in your throat for as long as I want."

Something in her tone made Marie shudder. She raised her gaze from Lexi's cock to the girl's eyes.

"Can you trust me with that, Marie?" Lexi asked, voice softening. Her tone remained serious, "I'm going to push your limits a bit. To do that safely, I need your trust. And I need you to try to push yourself only as much as you feel comfortable. Can you do that?"

Marie nodded, holding Lexi's gaze.

Lexi smiled, "Good slut. Open your mouth."

Marie moved forward to take Lexi's cock in her mouth and worship it, but Lexi moved back a step, just out of Marie's reach, taking her cock with her.

"I said 'open your mouth,' slut. Not suck my cock."

Marie swallowed, then let her jaw fall, eyes fixing on Lexi's wonderful cock. Her mouth started to water.

"Good slut. Tap my leg if you need to breathe."

Marie nodded, then drew in a sharp breath as Lexi pressed her cock against her waiting tongue. The spongey head felt incredible.

Fuck, I just want the rest of it in my mouth.

She shivered when Lexi threaded both hands through her hair, gripping her head tight, then gave her what she wanted.

Only at the last moment did Marie suck in a deep breath and try to relax her throat. She didn't do it in time, and gagged a little bit.

Lexi pulled her hips back, loosening her grip a bit on Marie's hair.

"Come on, slut. I know you can do better than that. You need to focus on what you're doing, not just on how much you want my cock in that slutty mouth of yours."

Marie blushed, not raising her eyes to Lexi's. She could do better.

I will.

"Sorry, Lexi," she said, "I'm ready this time. I promise."

She took a deep breath, then opened her mouth again for Lexi's cock. This time, she gazed up, meeting Lexi's eyes as the taller girl moved her hips closer. Marie felt the cock hit her lips and outstretched tongue. She opened wider, accepting Lexi's thick cock into her mouth, then relaxing her throat. She didn't gag this time. She swallowed Lexi's cock, holes clenching and letting out a moan as it stretched her throat, pressing deeper and deeper.

She kept going until nose pressed against Lexi's smooth pelvis, but where she would have stopped there, Lexi continued. She pulled Marie by her hair against her hips as hard as she could. It surprised Marie, and was a bit uncomfortable, but that was quickly overwhelmed by how insanely hot it was to just let Lexi use her like this. She continued swallowing, milking Lexi's cock as it sat sheathed in her throat. Marie watch as Lexi's eyes fogged over with lust, then closed as she took in a deep breath, breasts rising and falling with the action.

She held it there for a while, feeling her throat and jaw grow a bit sore. Surprisingly, that happened before her body told her she needed air. When Marie hit that point, something weird happened.

Marie became really wet. And floaty. It wasn't something she'd experienced before. She kept going--just like holding her breath under water--and tried to focus on exactly how long she could go without breathing, but it was hard. She was completely at Lexi's mercy. The woman's cock was down her throat, blocking any air from getting in, and it would only come out when Lexi decided to let that happen. It should have made her feel scared, instead...

Marie tapped Lexi's leg as her lungs began to burn. Her eyes went wide as Lexi pulled her long, thick cock out of Marie's throat in a single fluid stroke, and suddenly Marie was gulping in air, heart pounding. Her eyes were wide and her legs shaky. Thick strands of saliva hung down from her lips. She blinked when Lexi's hands left her hair and grasped her arms, pulling her to her feet with an ease Marie was a bit jealous of. She blinked, and found herself nose to nose with Lexi, a strange mix of concern and arousal in the girl's green eyes.

"Are you alright?" Lexi asked, bringing her hands to Marie's face.

Marie held her gaze and nodded slowly, "Yeah, that was--"

Lexi cut her off with a kiss that made Marie's toes curl and wracked her body with shivers. It left her breathless, and she couldn't help but grin at the spit that had transferred from her chin to Lexi's.

"What was that for?" Marie asked, voice breathy as her heart was still pounding.

"For being incredible," Lexi said, "That was really good, Marie. Did you like it?"

Marie thought for a moment, then nodded, "It was different, but good-different. It made me feel really overwhelmed, but safe, because it was with you."

Lexi smiled, and for a moment, Marie thought she saw the girl's eyes shine. Another kiss made her question that, as the shine was gone when Lexi pulled back, leaving Marie even more breathless than after she'd had Lexi's cock down her throat.

When Lexi let her hands fall from Marie's face, Marie sank back down to her knees. She looked up at Lexi to find the girl confused.

"What are you doing?" Lexi asked.

Marie frowned, "Don't you want to do it again?"

Lexi's eyes widened as a grin split her face, "Yes. But you've earned your reward, slut."

She gestured at her cock, and Marie blinked when she realized just how hard and soaked with her spit Lexi's cock was.

"Oh."

"Get on the bed," Lexi said, walking over to pick up a small container from the dresser where she'd set down her things, "I'm going to fuck that tight little ass of yours hard."

A/N: I hope liked that little training session <3
