Older Sister's Secret Box

Sweet and naive Alina was left home alone for the weekend. She was only eighteen, with long chestnut hair, expressive brown eyes, full lips, and smooth, delicate skin. She looked like a real doll, with a fragile body, a slender waist, and a languid, slightly bewildered gaze. It's worth noting that she and her sister were strikingly similar, like two peas in a pod. She was wearing a snow-white lace bra, accentuating her small, neat breasts, and thin, semi-transparent panties, barely covering her rounded hips and firm butt. She wore nothing over her lingerie—Alina moved around the house relaxed, enjoying the freedom, warmth, and

complete silence.

Peeking into her older sister's room in search of makeup, she opened one of the lower dresser drawers. Her gaze landed on a box. Lifting the lid slightly, Alina froze: inside lay neatly arranged vibrators of various shapes and sizes, anal plugs, dildos, nipple clamps, handcuffs, and several boxes of condoms.

Her cheeks instantly flushed. Her heart beat faster, her nipples hardened under her bra, causing a tingling excitement. She quickly glanced around—as if someone could see her—and with trembling fingers, took out the first vibrator. It was pink, made of matte silicone, with a ribbed texture and a rounded tip. Alina turned it on, and a light itch instantly spread through her lower abdomen. She ran the toy along the inside of her thigh, goosebumps running across her skin. The moment she touched her panties, a wave of arousal pierced her. The vibration pulsing against her clit elicited a quiet moan, and she squeezed her knees together, lay down on the floor, and allowed herself to sink into the new sensations. Her fingers gripped the toy, guiding it over sensitive spots until the fabric between her legs was soaked.

Next, an anal plug with a pink heart at its base ended up in her hands. Alina skeptically turned it over in her hands, licked it to taste it, and carefully began to insert it, pushing her panties aside. At first, it was unpleasant, but the pain quickly gave way to a warm pressure. She arched her back, feeling the plug settle inside, triggering a sharp wave of pleasure.

Then she decided to try a double-ended dildo—transparent, with textured veins, flexible. One end was narrow, the other wide. Slowly inserting the narrow end into herself, Alina moaned, enjoying the fullness, further enhanced by the plug. With her free hand, she moved the vibrator over her clit, biting her lip to keep from screaming. Her body writhed, every muscle tensed, her breasts trembled under her bra, her nipples rubbed against the fabric, adding sensitivity. Her sighs grew deeper, her movements sharper. And finally, overcome with ecstasy, she came. With trembling hands, she removed the vibrator, pulled out the double-ended dildo and the anal plug, leaving herself breathing heavily on the floor.

But her arousal didn't subside. She took out a vibrating egg—small but powerful. Inserting it deep inside, she decided to turn it to maximum, thinking the sensations would be weak. However, after the orgasm, she had become much more sensitive. The micro-vibrations spread throughout her body. Her fingers trembled, her knees buckled, she collapsed onto the floor and arched in pleasure. The toy was so powerful that Alina couldn't move—her body shook as if in convulsions. Her ears rang. With another wave of ecstasy, she screamed and came a second time, then with difficulty retrieved the egg by hand, feeling for it deep inside and pulling, slowly extracting it until it came out with a wet pop.

But the most impressive was the dildo shaped like a horse's cock—heavy, black, with a massive head and prominent veins. Its appearance was arousing in itself. Removing her lingerie and carefully folding it into the box, Alina lay on her side on the bed and cautiously began to insert the toy into her pussy. The friction was rough, the stretch intense, but she clenched her teeth and continued. Each movement spread her to the limit, causing an explosion of conflicting sensations of pain and ecstasy.

And suddenly—the jingle of keys in the lock. Alina flinched and, in panic, abruptly pushed the toy deeper—to the base. Sudden pain pierced her, her eyes widened, her mouth opened in a silent scream. She felt the dildo enter completely, filling her entirely. There was no time, no chance to remove it. She pulled her panties up over the deeply lodged toy and with all her might slipped into the closet, leaving a small crack. Hiding, she heard her sister enter the apartment, take off her shoes, and call for her. Every breath, every movement reminded her that a heavy silicone toy was pulsating inside her. She froze, her heart pounding in her ears.

Her sister, not finding Alina, assumed she had gone out on errands. Soon, there was a knock at the door—her boyfriend had arrived. Their voices grew closer:

"I got everything you asked for," he said, entering. "Here's a pack of new condoms. With tentacles. For your special pleasure, sort of."

"Oh, with tentacles?" her sister squinted, taking the box. "Mmm, you know I like it when it's not just warm inside, but when every centimeter teases and tickles... But wait, why only ten? Do you think that's enough for me?"

"Well, I didn't want you to think I'm a pervert. Although..." he chuckled and moved closer. "I remember perfectly how you moan already after the second round. You don't have to wait for me to finish... you love it when I just hold you, and you fuck yourself on me until you come again and again."

"Mmm..." she licked her lips and tilted her head. "Only if you hold me tight when I sit on your cock and move until my legs cramp. And don't forget, you promised to try me from behind... that's exactly what the tentacles are for—to tickle there too..."

"You really want me to stretch your ass today?"

"I want you to do it slowly... and for a long time. Until I start begging you to move faster... and deeper..."

They settled right on the bed, opposite the closet. Alina could see them through the crack—first talking, then kissing, then they started undressing. The bed creaked. The first slow movements soon gave way to fast, passionate ones. Moans, whispers, the sound of skin on skin. Alina pressed a palm to her mouth, and with the other—ran it over her belly, then lower, to her wet panties. The toy inside incessantly reminded her of its presence. The girl curled up, her body trembling. Vibrations of pain and arousal merged into one. They changed positions, tried different ones—missionary, cowgirl, from behind. They used condoms one after another. The rustle of wrappers, quiet curses, breathing could be heard. All this time, Alina remained captive in the closet, every sound amplifying her own sensations.

After perhaps two hours, everything fell silent. They fell asleep. Alina, barely breathing, crawled out on trembling legs. Taking a step was impossible—the pressure of the toy inside was agonizing. She crawled to the bathroom, turned on the light, and looked at herself in the mirror: sweaty, flushed, trembling. She tried to take off her panties—but realized: the dildo was stuck. Too deep. Too tight. Panic gripped her. She lay on the floor, pulled her knees up, and tried to push it out. Useless. A dull pain, growing anxiety. Tears welled up in her eyes.

Alina sat on the cold bathroom tiles, hunched over, breathing heavily. All attempts to remove the toy resulted only in dull pain and helplessness. Her muscles were tired, her fingers trembled, and her body felt like cotton wool. Now she didn't know what to do. Go to a doctor? Tell her sister? Or try again... but how? The toy was inside her—tight and secure. Exhausted, with a throbbing pain in her lower abdomen and a lump in her throat, she carefully curled up on the bath mat. "Just for a little while... I just need to lie down a bit, then I'll figure a way out of this..." she thought, not noticing her eyelids closing. Sleep came quickly. Without dreams, without movement, she slept until morning.

She sat up abruptly, spread her legs, and looked down. Indeed—the toy had apparently started to come out on its own during the night. The base was already pressing against the wet, cold fabric. Without wasting time, Alina got on her knees, lifted one leg, grabbed the protruding edge, and slowly, with effort, pulled. The process turned out to be agonizingly pleasurable—her muscles clenched around the toy, every cell responded. She almost cried out in pleasure when the dildo came out with a wet pop. Her body responded with a tremor, and Alina exhaled with relief. She immediately turned on the water, washed the toy, wrapped it in a towel, and pressed it to her chest. Now all that remained was to return it to the box and hope no one would wake up... and find out. Alina carefully stepped out of the bathroom and peeked into her sister's room.

Alina took a step inside, not taking her eyes off his body. Muscles, the definition of his abs, slightly tousled hair—everything about him was arousing. Inside her, an ember of heat still smoldered; the toy had only teased, not calmed her. On tiptoe, she approached the dresser, opened the drawer slightly, and returned the dildo to its place, carefully placing it in the box. Then she closed the drawer... and didn't leave. Her body ached, wanting release. The soft bed beckoned. She looked at the guy—he wasn't moving. Still asleep, and a note lay next to him. It read: "Love you, baby. Gone for a side job. Be back by evening."

Her sister's boyfriend stretched in his sleep, and a warm hand slid under the blanket, wrapping around her naked body. Alina held her breath as his palm landed right on her buttock, lazily squeezing it.

"Mmm, you're so hot..." he murmured hoarsely, without opening his eyes. His fingers confidently gripped her thigh, sliding closer to her crotch. "Already wet?.."

Alina bit her lip slightly, feeling her pulse throb in her ears. He clearly hadn't yet realized it wasn't his girlfriend in front of him, but her body could no longer resist—arousal washed over her, her stomach tightening with impatience.

"Didn't get enough? You want it early in the morning, huh?" he whispered, pulling her closer, his hard cock pressing against her thigh. "So insatiable..."

His hand was already confidently massaging her between her legs, two fingers sliding over her folds, easily parting them. Alina threw her head back, her body arching under him—he fucked her with his fingers, without any tenderness, hitting the most sensitive spots, causing hot waves of pleasure. Her legs trembled, her breasts quivered, her nipples chafed against the sheets, and each of his thrusts made her moan. But then he suddenly slowed down. Alina froze, her heart pounding, but inside, everything ached sweetly. His warmth, the strength of his hands, his closeness... She felt his arousal—his cock hardening, rubbing against her stomach. He removed his fingers, slowly inserted his cock, and fell asleep. The last thing he whispered was:

"Baby... I'm so tired... later..." and slipped back into sleep.

For several long seconds, she just lay there, breathing quietly. And then, with a sob, she slipped out, leaving her virginity to this guy.

The End.

Bonus:

A few days later, Alina wanted to check something interesting. She went back to her sister's room, sat on the floor, and took out the horse dildo. She took a measuring tape from her pocket, placed it at the base, and ran it up—35 centimeters. And the diameter at the thickest point was—8.5.

"Oh..." she moaned, running a finger over the silicone surface.

Her panties instantly became wet. She pressed the toy to her stomach, imagining it entering her again, and quietly said:

"You were made to tear apart, no doubt..." then kissed its tip. "Thanks for an unforgettable evening."
