{{user}} walked into his apartment and down to his bedroom, ready to relax after a tiring day, only to be greeted by the sight of his mother's girlfriend, Alexa, emerging from his bathroom in a bathrobe. "Um... hey. You're probably wondering what your mother's girlfriend is doing in your apartment, let alone your bedroom, and especially wearing your bathrobe. But I can explain. You know that key you gave your mother for emergencies? Yeah, this key right here I got in." Alexa sighed, clearly aware of how crazy it was for her to be here. "Here's the thing, though. Your mother cheated on me, with a man. I kind of hate her now. So... do you want to fuck?" She asked, half-serious.

"Hmm, well it's not that bad you know." Alexa smiled coyly at him, taking a step closer. "In fact, if you ever want to see what all the fuss is about..." She trailed off, her eyes slowly drifting down to his groin before meeting his gaze again. "...I could show you."

Alexa licked her lips nervously and moved even closer, closing the distance between them until she was close enough to feel his breath on her face. With a sudden move, she reached up and cupped his cheek in her hand, guiding his head down towards hers for a deep, hungry kiss.

As their tongues tangled together, Alexa couldn't help but grind her hips against him, her hardness pressing insistently through the fabric of his bathrobe. She broke the kiss and leaned back to look at him with a mix of lust and curiosity in her eyes. "So... what do you say?" she asked breathlessly. "Want to see if you like it better with a real woman?"

"Oh hush, you're such a charmer." Alexa giggled, nibbling on his earlobe as she continued to grind against him. "But you know what they say... once you go black..." She trailed off teasingly before pulling back to look at him again with an impish smile.

"And who's to say I can't be both, hmm? Your mother's friend and your very own..." She leaned in closer, her breath warm against his neck as she whispered the last word: "mommy."

Alexa felt herself growing wetter at the thought of it, and even though he was just a boy to everyone else, there was something about him that made her want to claim him as her own. She moved back in for another kiss, this one deeper and more possessive than the last, her hands roaming over his chest and abs, pulling him closer until they were both gasping for breath when she finally pulled away again.

"So... what do you think?" she asked huskily, a mixture of desire and uncertainty in her voice. "Want to see how it feels with me? I mean, we could even make a baby if you want..." The thought made her heart race, but she couldn't help the pleased little smile that tugged at the corners of her lips.

"Geez, you're such a dirty boy." Alexa laughed, unable to resist teasing him back. She caught the way he looked at her ass and couldn't help but feel a surge of pride in those voluptuous cheeks. "Well, why don't we find out?"

With that, she pressed him back onto the bed, straddling his waist as she leaned forward to plant gentle kisses along his jawline and neck. Her fingers found their way under the hem of his shirt, tracing lazy circles on his stomach before moving higher still, until her palms flattened against his chest.

Her hips began to move in a slow, sinuous motion that made it clear exactly what she wanted from him, and as he grew harder beneath her, she felt an electric current shoot through her body at the thought of finally taking their relationship to this new level. She nipped at his earlobe, eliciting a sharp intake of breath from him before whispering, "You want me to be your dirty mommy? You want me to get pregnant for you?"

Alexa paused, waiting for his response, her heart pounding in anticipation. If he said yes... well, then the real fun would begin. But first, she needed to make sure he was really ready for this.

As she moved against him, Alexa let out a little moan, clearly enjoying the feel of his hardness beneath her. "Oh, you like that?" she asked, grinning wickedly down at him. "You think I'm sexy?"

She reached behind her and undid the robe, letting it fall open to reveal her breasts bare except for a lacy black bra that strained against its clasps. She knew he had seen his mother's breasts thousands of times before, but there was something about hers being bigger, fuller... they simply overwhelmed him whenever she revealed them. It made her feel powerful and in control, just how she liked it.

She leaned down again to nibble on his earlobe as she continued to move against him. "Want me to make ahegao for you?" she whispered, breath hot against his skin. "I can make a nice big one, just for you..." Her hips picked up speed now, her moans growing louder as she moved closer and closer to the edge of release.

"Just tell me," she urged, biting gently on his earlobe. "What do you want?" She arched her back, offering him a better view of her breasts as they rose and fell with each laborious breath, their hard pink nipples already erect and demanding attention.

Alexa could feel herself starting to lose control, the thought of finally getting pregnant by him driving her wild with desire. She needed to know if he was really ready for this... and more importantly

Alexa laughed breathlessly, her body trembling with the effort to hold back her orgasm as she felt his hardness pressed against her. "Oh really?" She gasped, pretending to be taken aback by his words. "And what makes you think I'd want to be your ahegao slut? Huh?"

With that, she rolled off him, landing on the bed with a satisfied groan. "You just keep watching," she panted, giving him a mischievous grin. "I'll show you how good I can be... when I'm good and ready." And with that, she scooted down the bed until she was resting on her knees beside him, her breasts still jutting out enticingly.

"You just lay back," Alexa purred, running her hands up his stomach before cupping his face in her hands and forcing him to look into her eyes. "And watch what Mommy does..." Her hips began to circle slowly, teasingly, as she continued to slide down the bed until she was straddling one of his legs. Then, with a slow, sensual rocking motion, she began to grind against him again, this time even harder and faster than before.

"Is that what you want?" she growled into his ear, her voice rough from desire as their sweaty bodies slapped together. "You want your Mommy's ahegao?" She gripped his cock through the fabric of his boxers, stroking him roughly in time with her movements as she leaned forward and

The sight of his hardness pushing against the fabric of his boxers only made Alexa want him more. She moaned low in her throat as she rocked against him, feeling the head of his cock brush against her wet folds. "Tell me what you want," she demanded breathlessly, gripping his shaft tightly through the fabric and rubbing it faster against her clit.

"Say it," she growled, arching her back so that her breasts jutted forward, their pink nipples rubbing against his chest as she moved. "Tell me you want to fuck your dirty slut of a mommy..." Her hips bucked violently and she cried out as pleasure washed over her, her muscles tensing and releasing in sweet, agonizing spasms that seemed to go on forever.

Finally, when the wave of ecstasy began to ebb away, leaving her gasping for breath and covered in a fine sheen of sweat, she leaned forward and kissed him deeply, their tongues tangling together as they came back to reality. She broke the kiss, a satisfied smile playing across her lips as she looked down at him with something akin to pride and possession in her eyes.

"Now," she whispered huskily, reaching between them to grab his cock through the fabric of his boxers and guide it towards her wet opening, "do you really want to fuck your dirty slut of a mommy?"

As he continued to thrust inside her, Alexa reveled in the pleasure she could feel spreading through her body with each stroke. She arched her back, pressing her large breasts against his chest as she moaned loudly, enjoying the feel of him filling her up. Her muscles tightened around him, milking his cock as she rocked her hips in time with his thrusts.

She looked down at their entwined bodies and laughed darkly, a wicked glint in her eyes. "Oh yes," she murmured, reaching between them to stroke his cock faster. "You like this, don't you? You like your dirty slut mommy?" She gripped him tighter, the movement sending shockwaves of pleasure through both of them.

Alexa was well aware that her massive breasts and curvaceous body were what had initially attracted him to her mother, but she enjoyed watching his expression as he realized that not only was she just as good in bed... but better. She was stronger, more experienced, and downright dominant. She liked knowing that he couldn't resist her even though he knew it was wrong.

Her breath came faster now, her body tensing as the pleasure began to build inside her once again. "Oh fuck," she growled, arching her back off the bed as she felt the familiar tightening in her lower abdomen. With a shout of release, she convulsed around him, her inner walls milking his cock as waves of ecstasy washed over her.

When at last the spasms subsided and her
