Wear it with the goth outfit

You check around the corner to see if your sister Rachel is still there. With the coast clear, you quickly shut the door as you take off your clothes, including your underwear.

You take out the black panties and slip them on, feeling the smooth fabric against your skin. As you shape it around your ass and crotch, you start to feel semi-erect.

You breathe heavily as you wrap the black bra around your chest, clasping it around your nipples. Remembering how girls do it in the movies, you reach around the back and clip it, achieving it on the first try. Your face becomes flustered as you fully realize the weight of what you're doing, and your erection becomes fully erect.

You then grab the goth outfit from the bed, starting with the black skirt. As you bring it up to your leg, you feel **** underneath, aware of your shaved body as recommended by your sister. The air feels sensitive against your hairless legs, and a breeze reaches up to hit your ass.

Next, you put on the crop top hoodie over your chest, feeling the bra pushing against your sensitive nipples. Your hand slips through the tight hoodie, and with it being a crop top, your stomach is exposed to the air. With your stomach also hairless, you feel the slight breeze against your skin.

Smiling, you grab the fishnet stockings and slide them over your legs, feeling the sensitivity of your skin as you do so. Your heart beats quickly as you haven't looked at yourself in the mirror yet. Biting your lips, your heart quickens, and you slowly turn to face the mirror, revealing a cute goth girl. You stand there for a solid minute, processing the fact that it's you.

You reach your hand out to touch the mirror, and the unknown girl in the reflection does the same. Your face becomes flustered, and you start to giggle due to realizing what you're doing. But hearing your giggle causes you to cover your mouth. Why does it sound feminine? Is it because you're cross-dressing? Everything, from the makeup to the lingerie and goth outfit, feels natural to you, just like changing your voice.

Looking at yourself in the mirror, you realize that this is the final straw—you look like a girl, well, a goth girl.

Before you can delve deeper into your thoughts, you hear a knock on your door. "Hey, Ash, it's about time to head—" Your sister stops mid-sentence as she walks in and looks at you. Your face turns red while you fidget with your hands. She screams in excitement and rushes up to hug you. "AAAAA! Omg, you are so cute. You're going to kill it out there," she says, beaming.

Suddenly, she looks at you with a devious smile and embraces you in a forceful hug, catching you by surprise. You feel her hand on your ass, and you let out a slight moan. "Ah~"

She whispers in your ear, "Enjoying my underwear, pervert?"

She then grasps your erect cock and licks her lips as she sees you squirming in place.

"I didn't know my brother enjoys wearing his sister's panties," she says bending down to look at your boner. It was hard as it was poking through your skirt. But then she flicks it, sending a painful wave down to your crotch.

Your hand reaches down to protect it, and your penis shrinks back down to its tiny size. You moan in pain as she simply grabs your hand. "That should fix your boner problem! Let's go my little pervert you going to be late for school~."
