has her own technique

Nia too, is holder of the family alpha status and was initiated a long time ago in what she believes to be her family's superior special handjob techniques.

She applies a double-fisted reverse twist. She spits at Dan's cock and mixes it with his precum by rubbing the secretions into his large cock with her palm. Then she wraps both fists around his shaft, one near the base, the other just below the head. She rotates them both, one clockwise, one counterclockwise, then reversing them both to go back the other way again. She keeps that up, strictly on the shaft, letting Dan enjoy the build-up, right up until the moment Dan moans.

Nia then adds a lengthwise component to the motion, moving both hands up toward the rim of his cock head, then both back down toward his root, always twisting and twisting, in opposite directions.

This technique obviously works well if the cock is long enough to get both fists on it.
