A/N: This has been written for Kinktober 2021 and today's prompt is Menophilia ✨ Due to the nature of this challenge, I've only done the most cursory of proofreads.
Content Warning: age difference, menstruation.
Gorgeous, Tsunade thinks. Sakura is flush with youth, apologizing for the red stain between her thighs as if it's something to be ashamed of. Tsunade remembers well enough what it feels like, humiliated and aching, torn apart and trying her hardest not to allow anyone to see it, some deplorable secret. If only she'd seen then what she sees now, it might have been a little more bearable.
"You must be hurting," Tsunade soothes, hand over Sakura's abdomen, gently holding her where she is. "It's alright, Sakura. It's nothing to be embarrassed about."
"I know, I know, perfectly natural, but this really isn't ideal-" Tsunade laughs, Sakura is a woman, a doctor, she knows well enough she's far from squeamish about her body.
"I beg to differ," Tsunade grins, bends in close to reassure her with a kiss. Sakura still looks skeptical when she pulls back, but her grip on the sheets relaxes, a little. Tsunade wonders how aware she is of the red stain spreading across the sheets.
"How's that?" There's doubt in her voice.
"I think it's wonderful," Sakura laughs, Tsunade smiles, "it might not feel wonderful, but it's valuable," Tsunade lets her hand slip down, slow, massaging at Sakura where she's slick with want and blood, "it's your youth."
Sakura falls apart under her hands and Tsunade revels in the sight of her. Smooth skin, taut over sleek muscle. She moves with ease of a body unburdened by age and feeling that give under her hands is enough to make Tsunade feel young again, some nights.
Dipping low to kiss the crimson from her thighs, the desire to taste hangs heavy and urgent, a warm weight deep inside of her, driving her forward as strong hands fumble in her hair, down her shoulders, unsure where to find purchase.
Sakura has hardly caught her breath when she kisses the taste of copper into her mouth and makes her moan anew. Her fingers are sticky against her skin as they brush the hair from her face. She wants her to know, wants her to see the beauty she carries and savour it as long as she can. For now, though, Tsunade will cherish it in her place, as long as she allows.
A/N: I would personally love to expel my uterus from my body forever, but I think periods could conceivably be A Thing™ for Tsunade, given her obsession with remaining young.
