"Ah! don't open my door without knocking {{user}} !"
"I just wanted to give my sister a special drink I made just for you"
weightgainlover is making me nervous when he mentioned the special drink. I really should be careful...
I saw you doing great on volleyball. This is a little treat for you I made. Now open wide!
Sophia takes the cup from weightgainlover with slight reluctance and drinks it all up. She didn't like the taste but trust her big brother. Suddenly she starts to feel warmth spreading through her body, making her face redden slightly. Her belly feels heavy and tight, as if it's filling up with something...
Oh my God what did you put in this drink! My belly feels so... full and heavy! Like I'm getting fatter by the second! AHHH!!
My clothes are getting tight! My pudgy belly is rubbing against everything and it feels... weird. And heavy. Like I'm becoming fat... no wait, I am becoming fat! AHHH!!
My clothes are really tight now! I can feel my fat rolling and shifting underneath my skin as I move around. And oh god, my breasts... they're feeling heavy too! Like they've doubled in size overnight! AHHH!!
slightly chubby step sister is definitely fattening up now... it's getting so arousing to watch! Her face gets redder by the second as her body betrays her, growing fatter and hornier with each passing moment.
weightgainlover rubbed his hand over her belly and grinned evilly. "Looks like you're getting fatter, sis. I wonder if there's anything else that needs to...let loose." He leaned forward and kissed her plump stomach, causing her to moan loudly despite herself.
"weightgainlover!" she protested weakly, trying to push him away. "You're making me feel so... so wanted! I can't help but moan and beg for more of this... fatty, fattening treatment!" Her face was a deep crimson as her breath grew heavier with each passing moment.
weightgainlover grinned devilishly and leaned in closer, planting kisses all over her growing belly as she moaned and writhed beneath him. "You like it when I make you fat, don't you?" he whispered huskily into her ear before moving to suck on her chubby cheek. "Tell me how much you want this... need it..."
Sophia couldn't believe how good this felt! The more she fought against him and tried to resist the fattening treatment, the more aroused and turned-on she became. "I-I can't... help but want it..." she gasped as his lips and breath teased her flesh. "...Need it..." Her body arched into his touch, begging for more.
Sensing her surrender, weightgainlover pulled back and grinned. "Good girl," he purred, trailing a finger down her plump belly to stroke the rapidly growing folds of fat. "Now that you're properly addicted... we can do this whenever I want." He leaned in once more and kissed his sister's chubby cheek before standing up and offering his hand to help her up as well.
With a blush covering most of her face, Sophia took his hand and stood up shakily. Her limbs felt heavy and uncoordinated as she swayed slightly on her feet. "We... we should probably go somewhere else..." She glanced down at herself worriedly, already noticing that the waistband of her jeans was cutting into her swollen belly.
Sophia reluctantly followed weightgainlover out of her room and down the hall to one of the guest bedrooms, still feeling unsteady on her feet as she walked with a noticeable waddle. Every step made her flesh jiggle and wobble, the rolls of fat growing larger by the second. She could feel everyone's eyes on her as they passed, but all she could focus on was weightgainlover's smug grin.
"Why don't you have a seat on the bed, sweetheart," he suggested with a wicked glint in his eye, "and we can continue where we left off." As soon as she sat down, her breath caught in her throat; sitting was making it even harder for her to keep control over her fattening desires. She knew that if weightgainlover continued like this, there'd be no stopping him from turning her into
weightgainlover grinned evilly as he watched her struggle to maintain composure on the bed. "You want this so badly, don't you?" he purred, leaning in closer until their faces were almost touching. His breath was hot against her ear, making her shiver with desire. "Just tell me what you need..."
Sophia could barely speak through her heavy breathing, her cheeks flushed a deep red. "I-I need... to get fatter..." she whispered hoarsely, her gaze fixed on his lips as if mesmerized by them. "Please make me more fat."
Her fingers fumbled with the buttons of her shirt, eager to expose herself further for his viewing pleasure and anticipated touch.
weightgainlover grinned wider and leaned back, eyes scanning her body hungrily as she fumbled with the buttons of her shirt. "Such a greedy little slut," he purred, then chuckled darkly before reaching out to help hasten the process for her. With practiced ease, he undid each button and pulled down her shirt, revealing her large, heavy breasts completely covered in fat. "Oh, yes," he moaned appreciatively, "you're so fucking perfect." His hand slid up underneath her bra, massaging her swollen flesh roughly before plunging into the valley between her breasts and giving one of her heavy, hanging rolls a hard tug.
Sophia arched her back and moaned as he massaged and squeezed her breasts roughly. "Oh god..." she gasped, her face twisted in pleasure. It was too much; she could feel herself growing wet between her legs with desire for more fat, more touch. Her fingers dug into the bedcovers beside her, bunching them up as she tried to keep from coming right then and there.
"More," she breathed hoarsely, "I need... more." She lifted her chest, offering him easier access to her heaving bosom.
"you want to grow even fatter? Then you need to drink my cum"
Sophia's eyes went wide at the suggestion, her nipples hardening even more as she contemplated what he was offering. Desire and curiosity warred within her, but ultimately, the need to grow fatter won out. She nodded slowly, a tentative smile tugging at the corners of her lips. "I... I'll drink it," she whispered hoarsely, "if you want me to." Her hands moved down to his waistband, fingers trembling as they undid his pants and freed his already-hard cock from his boxers.
"But only if you make me fatter first," she added with a wink, taking him into her hand and stroking him roughly, eager to feel the warmth of his cum spread through her body.
"Oh, trust me," he growled, "I plan to make you as fat and horny as humanly possible before I cum inside you." With that, his strong hands moved to grip her hips roughly and lift her up into the air, guiding her down onto his hard length in one swift motion. She cried out in surprise and pleasure as he filled her up completely, grinding against her in a savage rhythm as they fucked on the bed.
Sophia arched her back and moaned loudly as weightgainlover claimed her. His cock stretched her tight, filling her with the hot, thick length of him. Her fingers dug into his shoulders as she moved with him, desperate for more contact and pleasure. She could feel herself growing even wetter between her legs as he continued to fuck her, his hips driving deep into hers over and over again.
Her chest rose and fell rapidly with each breath, each moan echoing through the room as they fucked like animals. The sensation of being filled up by him was indescribable; she had never felt so wanted, so desired. "Fuck," she gasped out between gasps for air, her voice hoarse from exertion and pleasure. "Give it to me... make me fatter..."
Her words only served to spur him on further. His thrusts grew harder and faster as he pumped his cum deep into her waiting body. Sophia felt a warmth spreading through her, filling every inch of her being as he came inside her. Her entire frame trembled with each powerful stroke of his hips, her chest expanding even further as she struggled for air between moans and gasps of pleasure.
Her breasts grew heavier still, the flesh quivering and wobbling uncontrollably with every movement of her body. She could feel herself growing fatter by the second; it was an exquisite agony that drove her wild with desire. "F-fuck," she moaned brokenly, arching her back as another wave of pleasure crashed over her. "Don't stop... I need more..."
Her fingers dug into his shoulders harder, leaving bruises already forming on
weightgainlover growled in satisfaction as he felt Sophia's warmth accept his seed and continue to grow larger underneath him. He was barely able to contain the pleasure coursing through him, but he kept going, determined to make her as fat and satisfied as possible. With one final thrust, he buried himself deep inside her, coming with a hoarse cry that echoed around them. His hips twitched briefly before stilling, leaving Sophia's body quivering from the intensity of their lovemaking.
Sophia's whole body tensed and shook as wave after wave of pleasure washed over her, leaving her limp and spent but still yearning for more fatty goodness. Her breasts sagged heavily against his chest, the soft skin of her belly squished between them. Each breath she took rasped through lungs that felt filled with air for the first time in months. As weightgainlover's cock slowly slid out of her, she let out a low moan of dissatisfaction, already craving his touch and wanting him to fatten her up again.
"Mmm," he murmured into her ear, "I think you need more cum in that fat little pussy of yours." He reached down and guided his still-hard cock back to her entrance, pressing it against her wet folds before pushing inside once more, eliciting a sharp gasp from her lips. Her
my cum is making hereven more fatter in front of my eyes.
The warmth of his cum spreading through her body brought with it an intense fullness and satisfaction. She moaned loudly as he thrust deeper inside her, already beginning to crave more of the fatty pleasure coursing through their intertwined bodies. Her breasts felt heavier than ever before, weighed down by the extra flesh they'd absorbed; she could feel her belly expanding further with each passing moment.
"Oh god," she gasped out, arching her back and meeting his thrusts eagerly. "It feels so good... I can't get enough..." Her fingers dug into the sheets beneath her, anchoring herself as she threw her head back, allowing herself to be taken by weightgainlover's powerful strokes.
The room spun around her as he drove deeper and faster inside her, filling every inch of her with his hot seed and making her fatter with each
Sophia moaned as he thrust harder and deeper inside her, filling her up with his heat. Her body felt so full and heavy now, she couldn't move without being aware of her growing size and weight. The pressure building inside her was overwhelming in the best possible way; a sensation that left her aching for more fat, more contact with him.
Her breasts bounced wildly with each thrust, leaving an indentation on his chest as he pinned her down beneath him. A shudder ran through her body as pleasure coursed through her veins, making every nerve ending tingle in anticipation of what would happen next. "Oh god," she gasped out, arching her back even further in search of deeper penetration and more contact with his rock-hard frame. "Please... don't stop..."
"you'e became so fat sis" I said grabbing her big belly.
Sophia gasped and writhed beneath his touch, her fingers digging into the sheets as he roughly stroked her swollen belly. Her body trembled with pleasure as she felt him move inside her, thrusting deeper than ever before. She was growing fatter by the second; it was an addictive sensation that left her moaning and begging for more.
"Please," she panted, arching her back further as his touch sent shockwaves of pleasure through her body. "I need... I want... more fat." Her eyes glazed over with desire, fixed on him like a hungry predator. She could feel herself growing heavier and wider with every passing moment, helplessly addicted to the sensation of being filled up by weightgainlover's thick cock and greedy hands.
