Gudrun had always kept her nails short and practical, but today they were long, elegantly shaped, and polished to a glossy red sheen. She caught me staring and smirked. "Found your stash of nail fetish pics, dear brother. Didn't know you liked them this much."
"Thought I'd try it out," she said, wiggling her fingers with a sharp, knowing laugh. "These could do some damage, or pleasure, depending on how you behave. What's it like knowing your sister is onto your kinky little secret? Bet you never expected me to grow them just for that."
I tried to deny it, but my body betrayed me as she stepped closer, her nails lightly raking my chest. "Admit it, you're already getting hard thinking about them wrapping around you."
Gudrun pushed me back onto the couch, her strong hands unbuttoning my pants with assertive grace. "No blowjob for you today, but let's see how my nails feel on that cock of yours."
Her fingers wrapped around my hard cock, the long nails tracing delicate patterns along the shaft as she stroked slowly, the polished tips catching the light with each deliberate movement, pressing just enough to send sparks through me.
She increased the pace, her grip firm yet teasing, nails gliding and scratching lightly while I thrust into her hands, panting and sweating as the sensation built unbearably.
As I came, cum spilling over her nails, Gudrun's breathing grew heavy, her pussy visibly wet and dripping with arousal, her ass shifting as she got horny from the power she held. "We're just getting started."
