Face-down, grinding on her cupped hands

"Don't leave, Mum," Annie pleaded. "Your room is ever so cold and I don't want to be alone."

"Oh, Annie, Annie dear," Lucy said. "Very well. Let's have you settle yourself and then we'll get you back to bed."

Annie burrowed herself face-down into the bedclothes. Lucy moved aside, sitting on the edge of the cot and letting Annie spread her knees. Annie moved her hands down and cupped them over her mound. Her buttocks stuck up a little bit.

Lucy watched as Annie stimulated herself. Annie's hips tilted up and down as she ground her feminine parts into her cupped hands. Annie's breath hissed through her nose. Even in the cool air of the airship storeroom, Lucy scented her daughter's womanhood, sharp with arousal. Annie's scent reminded Lucy of one of the maids, long ago, whom Lucy had caught masturbating while watching Edmund cover Lucy. Edmund hadn't seen. Lucy hadn't said. Lucy and the maid had kept one another's secrets.

Annie whimpered into the pillow as her excitement rose.

Lucy bent over Annie's ear. Sabrina's heated cunt scent tickled Lucy's nose. Had Sabrina returned Annie's Sapphic kisses? Lucy whispered, "Are you thinking of Sabrina now?"

"Yes, yes," Annie said. Her bum rose and fell, grinding her sensitive parts into her hands, like dough eager to knead itself. There was a faint squishing sound now that Annie's moisture had descended.

"You can always remember her with joy," Lucy whispered to Annie. Her taste, Lucy thought.

"Oh, oh, oh," Annie said. Her hips moved faster, losing their steady rhythm. "Ohhh...!"

Annie buried her face in the pillow, stifling her moan of climax. Her body went stiff as from a galvanic shock. Her bum slackened, then clenched and ground downward. Again. Half a breath. Again. Once more. Then a last tight clench before Annie sighed and went limp.

It hadn't been loud. Someone asleep in the next bed might not have heard.

Lucy put her hand comfortingly on Annie's lower back.

"Oh Mum, oh Mum!" Annie said. Her hips pumped once more, her mother's touch releasing a final spasm of climax. A little pattering sound of droplets witnessed to Annie's wet spend. The scent of young female arousal freshened.

"Annie, oh Annie dear," Lucy said. "Come, let's take you back to bed."
