Wrapping my lips snuggly around the base of my little sister's glans.
She squirms under my hand and I pat her tummy reassuringly.
Slithering my tongue over her cockhead. Tasting, feeling, exploring it.
Her breathing quickens and deepens. I can feel her chest rising and falling through my fingers.
I lick up her pre, letting out a soft "mmm" around her cock.
She giggles a little at the sound.
I press my tongue to her head and begin to swirl it around, getting faster and harder as I go.
Her breathing quickens again. I can hear the sheets rustling as she grasps them to steady herself. I lay my free hand on one of hers and she holds it needily.
I rest my tongue and begin to suck. Gently at first, but steadily getting stronger.
She squeezes my hand. her legs twitch against me.
I suck hard, squeezing her hand back and holding my hand firmly to her stomach.
Still tightly squeezing my hand she lets out a few adorable moans. Then squeezes my hand even tighter and speaks. "b-big sis, too-too much."
I relax my mouth and gently pull off of her. "You need a break sis?" I look up at her.
She nods, her breathing beginning to settle.
"Okay, sounds good." I squeeze her hand. "Are you having fun?"
"Okay, let me know when you're ready again."
