That summer, Dad rented a vacation cabin. But there was a problem. "The cabin's too small. Jason, you and your sister will have to share a bed."
Candy flipped me off. "I'm not sharing a bed with my jerk brother! He can sleep in a ditch!"
Mom yelled. "Stop arguing, you're both over eighteen. Just put some pillows between you."
We reached the cabin after dark. Candy looked at the bed and then at me. "Jerk, let's just get through the week. And I'm first in the shower."
I sat on the bed wearing only my boxers. Candy came back wearing a too-tight T-shirt and no bra. Her hard nipples poked out of the thin fabric. She sat on a chair and lifted one foot on the bed to polish her toenails.
Suddenly, I had a perfect view of her tight panties. Panties that barely covered her pussy. I pretended to check my phone as I checked her out her twat. My dick perked up when I saw wisps of blonde pubes curling out the sides.
Through the sheer fabric, I could make out her dark pink slit... Sis was hot! I was mesmerized by her twat.
"Dammit Jason!" she yelled. "What's going on in your shorts?" I looked down to see a tent pole rising up in my boxers. Grabbing a pillow, I covered it.
"Jason, are you watching pornos on your I-phone?"
"No."
"Frikin' liar." Sis shook her head and went back to polishing her toenails. She lifted her right foot onto the bed... as she lifted, I saw her tight panties wedge into her pink slit. Again I was transfixed by twat.
"Like the view between my legs!?"
"I wasn't looking."
"Yes, you were Perv!" Sis yanked the pillow off my lap. "Ha, I see Mr. Happy popped up again." Candy stared at my lump. "Does it feel good?"
"Does what feel good?"
"Your erection, does it feel good? Tell me!"
"Yes dammit. It feels so good it hurts."
"Jason, can I see it?"
"No!"
Sis still had her feet on the bed. I noticed a growing wet spot on her panty crease. Candy winked. "Does staring at my panties make you hard?"
"Not your panties, sis. Your pussy. I can see it."
She pulled up her shirt and looked. "See it's covered."
"Yes sis, but the fabric is see-thru. I can see your lips, your slit, and curly pubes poking out the sides. Sis, I didn't know you had a blonde pussy."
Candy pulled her panties tight as more pubes bulged out the sides. My cock jumped in approval. She laughed. "Does my blonde twat make you hard?"
"Hell yes. So hard it hurts."
"You want me to cover myself to stop the hurt?" I shook my head. Candy giggled and leaned back, spreading her legs wider.
"Sis, why do you want to see my boner?"
"I've never seen a hard one."
"But you had a boyfriend last year. Didn't you see his prick?"
"We only did it once. In the dark...Jason your cock lump makes me wet." Candy leaned back, lifting her hips to show her wet spot. "I'll show you my cunt if you show me your cock."
"DEAL! On the count of three." My heart pounded in pussy anticipation. "One... two... three." Candy slipped her panties down and flipped them off her foot. My shorts dropped as my boner lunged out, stiff and proud.
Sis gasped. "Holy shit, it's huge and scary as fuck." I tried to cover my erection, but Candy stopped me. "A girl has to face her fears."
As she stared at my prick, I gazed at her heart-shaped twat. Wispy blonde pubes framed her puffy pink lips, and her swollen clitty peeked out from the top of her glistening slit. Candy rubbed her moist mound. Teasing me.
