Wet thighs press together as she arches into the mattress, fingers working a thick toy in slow circles. Heavy tits rise and fall with each breath, her free hand gripping the sheets until they bunch white-knuckled. The toy buzzes louder, her back bows off the bed as she bites her lip hard. Pleasure flushes her chest pink while her hips rock in time with the vibrations. A quiet moan escapes before she collapses back, spent but still twitching.
