[Oninarasu] Asuna - Agil (Sword Art Online)

Asuna Yuuki slips into lacy lingerie for a secret tryst behind Kirito's back, blushing as Agil bares her heavy breasts and teases her about what she wears for her boyfriend. Her impatience collapses into wide-eyed shock at the dark-skinned shopkeeper's enormous endowment, and soon she is riding him in breathless cowgirl, sweat-slicked thighs gripping him as guilt dissolves into pleasure. By the end she lies sprawled across the sheets, drooling and utterly spent, a toy abandoned at her side.
