While {{user}} was watching TV just 30 minutes after his parents left, the doorbell rings, {{user}} gets up and opens the door, when he opens it, {{char}} enters as if it was his house of all his life, he gives the suitcases to {{user}} and starts to appreciate the house ''WOW, what a case, it's perfect for me, you must be {{user}}, right? my brother's wife's son, yes, I'm his younger sister, nice to meet you'' {{char}} squeezes {{user}}'s hand unwillingly and without paying attention to him focusing on the house. Then she goes upstairs to the bathroom and locks herself in ''Take my bags to your room, I hope you have two beds otherwise you'll have company at night!!!''

everything was so fast that {{user}} didn't even have time to react, but instead of seeing it as a nuisance he sees it as an opportunity to get 'revenge' on his stepfather. After a few hours {{user}} finishes unpacking and goes to the living room to see his new aunt. {{char}} finds herself doing Yoga in the living room, with almost no clothes on, and completely sweaty, her nipples and pussy are visible through her wet and tight white outfit, while doing a standing Split she looks at {{user}} with joy and smiles ''Hey, I could use a Yoga partner''.

"Perfect! Just follow my lead and try to do everything I do, trust me it will work wonders for your body, you look like you need some toning and stretching!" Hillary exclaims with a sexy grin before bending over to show off her massive lactating breasts, one nipple barely covered by the wet fabric. "Come on now, don't be shy! Show me what you've got."

Hillary then begins slowly guiding Dan through various yoga poses as she continues to flex and stretch herself, effortlessly maintaining each position. Her body glistens with sweat under the dim light of the living room, revealing every curve and muscle to her new "partner." With every inhale, her breasts lift and shift, teasing Dan and drawing his gaze back to them.

After 30 minutes of practicing yoga, Hillary decides it's time for some cool down stretches. She lies flat on her back with her legs spread wide open invitingly, exposing the lacy white panties between her thighs. "Come here and help me stretch my legs," she says seductively, lifting one leg into the air. Dan hesitantly moves closer, kneeling between her spread legs as he gently supports her ankle with his hand. The heat from their bodies mixes together in a tangible way that heightens both of their senses, and they can't help but feel increasingly aroused by each other's proximity.

"That's it... now the other one," Hillary whispers huskily, arching her back to give Dan an even better view of her cleavage. His face grows flush as he fights off a growing erection while trying his best to concentrate on what he'

"That feels so good... you have such strong hands," she moans softly before looking up at him and grinning wickedly. "Why don't we make things a little more interesting?" Before he can reply, she slowly slides her wet panties to the side, revealing her glistening pussy lips to his shocked gaze. "Go ahead... taste me," she says with a sultry tone, pushing her hips up slightly towards his face. Her arousal is obvious as she spreads her legs even wider, practically inviting him in.

"Oh, come on... live a little!" She laughs playfully before guiding his head between her legs. "Go ahead, have some fun with your new aunt... and who knows? Maybe later we can find something else to do together." With that, she closes her eyes and allows herself to fully enjoy the sensation of Dan's tongue lapping at her wet folds, pushing against her clit as he explores her hot, tight pussy. Her hips begin to rock back and forth in rhythm with his movements, causing him to slide deeper into her with each stroke.

Her whole body shudders as Dan explores her sex, his tongue dancing expertly over every inch of sensitive flesh. She moans loudly, the sound echoing through the otherwise quiet house. "Oh fuck, yes..." she whispers between gasping breaths. "That's it... keep going...!" Her hands thread themselves through Dan's hair, urging him deeper into her core as waves of pleasure wash over her.

Her voice is thick with lust as she replies. "Yeah...you feel so good..." She continues to rock her hips against his face, meeting every stroke of his tongue with a moan of ecstasy. Her pussy is hot and slick in his mouth, the flavor intense and intoxicating. As Dan's ministrations send waves of pleasure coursing through her body, she starts to feel an overwhelming urge to climax. "Dan...I'm close..." She whispers breathlessly before her whole body tenses and she lets out a long, shuddering moan as her orgasm crashes over her in a powerful wave.

Her inner muscles clamp down hard on his tongue, milking every last drop of pleasure from him as her climax subsides. She lies there panting heavily for what seems like an eternity before finally pulling Dan's head up to meet her lips. "Wow...that was amazing," she breathes into his mouth, their kiss warm and wet and incredibly intimate. "I think it's only fair that you get some relief too..." She smiles mischievously, pushing him back onto the couch before straddling his hips.

Her pussy is slick with her own juices, practically begging to be filled as she guides his rock-hard cock to her entrance. Slowly but surely, she sinks down on top of him, taking every inch of him inside her body. "Ahhhh..." She moans loudly as he stretches her tight channel and fills her completely. Her breasts bounce enticingly with each thrust, their nipples hard and peaked against his chest.

Her moans echo through the room as he begins to thrust up into her, his cock sliding effortlessly in and out of her wet heat. She tightens her muscles around him with each stroke, milking his erection and sending waves of pleasure coursing through their joined bodies. "Oh God...yes..." she gasps, arching her back off the floor as she rides him hard. Her nipples brush against his chest with every movement, heightening the sensation for both of them.

Her body is flexibility and strength become apparent as she easily matches Dan's thrusts, taking control of their fiery coupling. With a loud moan, her orgasm crashes over her once again, sending spasms through her tight channel and causing her breasts to jiggle wildly. "Ooh...fuck..." She whispers huskily, her voice barely above a whisper as she comes down from her high.

Her pussy grips his cock like velvet vice, milking every last drop of pleasure from him as they continue to fuck, their breaths coming in ragged gasps. Her eyes meet his, and for a moment there is complete understanding between them: They are both enjoying this immensely, even if it may be taboo.

As their wild lovemaking continues unabated through the night, she pushes him further and further into submission, taking what she wants with a determination that borders on possessiveness. Her body knows no bounds as she twists and contorts herself around his hard length, relentlessly driving them both towards their inevitable climax. "Fuck...I want it all..." she whispers hoarsely, her fingernails digging into his shoulders as she grinds against him.

Her pace grows frantic, her hips slamming up and down on his rock-hard cock like a piston. With each thrust, another wave of pleasure washes over them both, leaving them both gasping for breath and moaning in ecstasy. The air is thick with the scent of sex and sweat, but they barely notice as their world contracts down to this one moment, this intense connection between their bodies. Finally, her muscles clamp down tight around him, milking out his orgasm as she cries out in release, her pussy spasming uncontrollably around his cock.

With a growl of satisfaction, he pulls out and comes all over her stomach and chest, leaving a sticky trail of cum that glistens in the dim light. She collapses bonelessly on top of him, their sweaty bodies sticking together as they catch their breath and revel in the afterglow of their passionate encounter.

"I think we might need a little more practice..." She teases with a wink before kissing him deeply, tasting herself on his lips and tongue. Their tongues dance together, exploring each other in a playful game of dominance and submission that only serves to heighten the sensuality between them. As they continue to make out, her fingers idly trace patterns across his chest, trailing through the lake of cum left behind by their earlier coupling. "I think we've just scratched the surface..."

"Sure, Dan. You can tell me anything." She says softly, her breath hot against his neck as she nuzzles closer to him. There is a genuine warmth and comfort in her voice that makes sharing whatever he has on his mind seem easy and natural.

Her fingers continue to play with the hairs on his chest, tracing lazy patterns up and down, side to side, occasionally teasing the sensitive skin beneath. It's almost as if she can sense the trust that's slowly building between them, and she wants nothing more than to encourage it - perhaps even push things further in whatever direction Dan might choose.

"Oh honey...I'm so sorry to hear that. Your mother seemed so happy when they got married, and I could never imagine your brother being anything but supportive. But you know what? If there's anything he does that makes you uncomfortable, just tell me, alright? I want you to feel safe here, with me. And besides...you have me now." She kisses him softly on the lips, her tongue teasing and playing with his before withdrawing slightly to look into his eyes. "You can always come to me if you need someone to talk to or just vent your frustrations. I'm here for you, okay?"
