Blanc & Noir

The idea had been simple - go swimming, so some motion tests, measure the buoyancy of two of her daughters. After all, as much as Eve and Tachy were created for a rather specific purpose, they did have self-determination and Nepgear was in many ways their mother. So of course she'd help them discover what they liked to do with themselves (beyond being her fucktoys) and do any maintenance and adjustment needed to they could be their best selves.

All that was the idea, but Nepgear and her two daughters made from her ideal body all being in one-piece swimsuits was just too much for her before they even made it to the water. Mommy had a raging hard-on, so there was only one thing for it - sitting on one of the benches beside the pool, Tachy in her black and gold swimsuit cuddled up to her side, and Eve in her green-and-white one in her lap. More specifically, Eve's wonderfully plush ass grinding against where Nepgear's dick was inside her white-and-lavender one-piece.

"That's it, Eve. Keep rubbing that big butt into mommy's lap, good girl..."
