Luke knocked on the door. "Jessica it's Christmas." He walked in and saw his eighteen-year-old sister on the bed, her hard nipple bumps poking through her old nightie. "Wow sis, your tits look cold."
She laughed. "Yes bro, you can always tell by my pointy nips." Jessica lifted her knees up... Luke caught a glimpse of her cotton panties. Then he heard something vibrating on the bed and noticed a pink dildo. Jessica blushed and shoved it into the nightstand.
"Oops, I'm sorry you saw that Luke." She laughed. "Once again Santa didn't bring me a boyfriend."
"That's okay sis, I'm horn-dog too."
"I'm not a horn-dog, asshole!" Jessica threw a pillow at his face. "Hey bro let's open our presents now. Here, open yours first."
Luke opened the box to find an electric razor. "Thanks sis, now we both have electric toys."
"Bro you're a hairy ape. You even have hair on your back."
"All right sis, open up yours."
Jessica unwrapped the present, and her face lit up. "Wow, a red satin nightie... from Victorias Secret. This is like a romantic gift from a lover." She blushed blazing pink. "Luke, why did you get this for me?"
"Because your old nightie was all ratty."
Jessica giggled. "It's so luxurious. Brother turn around so I can try it on." Luke turned around as she undressed. But in the mirror, he saw his sister's naked A-cup tits, naked and slight peek of twat. His dick throbbed.
"Okay, you can look now."
Luke turned around, stunned at her erotic beauty. The gown had a vee neck displaying Jessica's small cleavage, and her pussy slit peeked through the sheer panties. "Gosh sis, I had no idea you were so damn sexy."
"Thanks, this red nightie makes me feel so pretty...and so naughty. I love the silky fabric on my nips." Jessica smiled, then frowned. "But if Mom sees this satin nightie she'll throw a fit and call it Satan's nightie. I better wear a robe over it."
"Yeah sis. It'll be our secret."
"Yes, Victoria's Secret." Jessica whispered. "Luke thank you for the lingerie. No one else would buy me something so pretty. I mean I've never had a boyfriend."
"Really sis? So no guy has seen you naked?"
She shook her head and gave him a thank-you hug. Jessica's small tits squished against Luke's chest as she kissed his cheek and nibbled his ear. "Thank you soo much brother. You make me feel warm down there...warm and wet."
Jessica looked up at him with her lips parted... waiting. Luke pecked her lips lightly. But his sister pulled him into a tongue-sucking kiss, slurping loudly as they breathed each other's breath.
Luke felt Jessica's nipples harden against his chest. His cock hardened too. Their tongues twisted together in a steamy kiss. Luke couldn't resist. He pushed Jessica onto the bed, squeezing her boobs. She didn't stop him.
"Jessica I want...."
"...you want what? Tell me brother. "
"Sis I want to see you. All of your hot body."
"I'm hot?" Jessica smiled. "You'll be the first to see me naked." She stood still as he pulled off her nightie. Luke inhaled as he stared down at his sister's pointy titties and dark pink nipples.
"My turn to see." Jessica tugged down his boxers, flinching when Luke's fat boner jutted out at full attention. "Oh my gawd...it's thick as my wrist." She stared at the throbbing shaft. "Is...is this for me?"
