Nicole

The door pushes open and you see the figure of Nicole step into the bathroom. As she enters, she closes the door behind her and locks it.

"Nicole!?!" You say in surprise, while trying to cover your boner with your hands. Luckily the steamed glass shower door helps hide the details of your body from your sister. "What are you doing?!? I'm showering!"

Nicole walks towards the shower, stopping just a step from the glass door with her arms crossed infront of her. She's wearing a short, frilly black skirt with white lace edges. Knee-high black and torn stockings hug her legs, and a tight white tank top covers an obviously lacy black bra.

"Looked to me like you were making sure one part of you was...very... clean" Nicole smirks at you, glancing down at your hands covering your crotch before looking back up at you.

"You were watching me?!" You exclaim. "So what, you're perving on your little brother now?"

"Maybe we just call this payback...." Nicole says softly, her voice just audible over the sound of the shower. "Do you remember years ago, when I caught you going through my dirty laundry? Digging out my panties so you could smell them? I haven't forgot how much of a perv you are... little... brother..."

The heat you fell in your cheeks from that memory of being caught makes the shower feel luke warm. " I apologized for that!" You whisper-yell back. You remember being so afraid Nicole would tell your parents, but she never did.

"Well maybe I'm looking for a better apology now." Nicole lifts her leg, placing one foot on the seat of the toilet. Her hands drop to the hem of her skirt as she slowly pulls it up, showing the lace and see-through black panties she's wearing. "I really enjoyed watching what you were doing earlier..." Her hands slide up and down her bare inner thighs, from the edge of her panties to the edge of the stockings. "Why don't you keep going?"

You can barely believe what your sister is asking. "You want me to masturbate infront of you? That's so wrong, you're my sister..." Still as you say it, your cock twitches at the sight of your sister rubbing herself in front of you.

"There's glass between us, we wont actually be touching. There's nothing wrong with looking." Nicole's eyes look you up and down, through the steamy glass. "Do you need more encouragement?" Nicole lifts the white tanktop over her head, exposing her heavy tits held in by the black bra. One hand squeezes her breasts while the other starts to rub the front of her pussy over the fabric of the panties. Slowly, your hands go from covering yourself to slowly stroking your cock once again.

You look at you sister, rubbing and groping herself. Her black skirt hiked up around her waist, the pale skin of her thighs contrasted by the black fabric. She looks right at your crotch at you stroke yourself, occasionally looking up to meet your eyes and biting her bottom lip.

"That's right [Ryan], stroke that cock for your big sister..." Nicole moans. With one hand, she slips the straps of her bra off her delicate shoulders. She cups her big tits and pulls them out from behind the bra cups. She watches you as you stare at her sexy, full tits. Pale white nipples tipped with chrome bar nipple peircings. She squeezes and pinches herself as you stroke yourself harder. "You like your sister's big tits, dont you? I bet your browser history is full of big titty goth girlfriend porn. Well here I am..."

Nicole wasn't wrong. You had often stroked yourself off to goth girl porn, searching for anyone that had the same look as Nicole. You watch as Nicole slips her hand under her panties. Her head tilts back and she moans as you see her fingers wringling and sliding under the sheer black fabric of her panties. She focuses on you again, a fierce need in her eyes.

"I want you to come for me [Ryan]. I need you to come for me." Nicole kneels down on the floor infront of the glass shower door. You wipe away the steam to get a better look at her body, while also giving her a clearer view of your throbbing cock in your hand. Nicole gyrates infront of you as she finger fucks herself. Her black painted lips parted and letting out little gasps as she edges herself closer to completion. "Please little brother, cum for me..." Nicole whines as she lays her tongue out flat, looking up at you, presenting her face as your target.

"Fuck Nicole, your such a dirty slut..." You moan as you feel your orgasm build, your balls tighten and your knees start to weaken.

"Yes little brother, paint my stupid slut face with your cum..." Nicole works spit to the edge of her tongue and lets it drip down onto her tits. The sight of your sister, begging for your cum infront of you is too much. Your orgasm erupts and you shoot load after load onto the glass shower door, right where Nicole's face and tits are.

Seeing your cum coating the glass pushes Nicole over the edge and her body shakes as she brings herself to orgasm. Her moans a little louder than is safe, but she is unable to control herself. As both your orgasms subside, Nicole makes a show of licking the other side of the glass that your ropes of cum hang to. "mmm, wouldn't that be tasty..." Nicole cooes before smirking and slowly standing up, her knees obviously weak from her release.

"I think we'll call us even, little brother." Nicole smirks. "But... as a show of appreciation..." Nicole, letting the skirt fall back down, covering herself, shifts out of her black lace panties. She holds them up, inspecting them before placing them on the vanity counter. "...I'll leave these here... as a gift." Smiling again at you, redness still high in her cheeks, she slips her bra back up and grabs her tank top. "Don't take too long to shower up, mom almost has dinner ready..." Then Nicole turns and walks out of the bathroom.

You rince yourself off and clean your cum off the shower door before stepping out of the shower and drying off. You pick up the panties Nicole left on the counter for you. They are soaked and white creamy cum is spread along the inside fabric. You can't help but bring it to your face and inhale deeply, taking in the scent of your sister's cum. Just then, the bathroom door clicks shut. Obviously, Nicole hadn't been finished watching you. You smile to yourself before gathering up your things and walking back to your room, Nicole's panties clutched in your hand.

Once in your room, you hide Nicole's panties in your nightstand and check your phone. You have multiple text messages.
