Ochaco's Milky Tits

The moans of Ochaco as he caressed her breasts gave him a idea. Sure, she was already perfect in his eyes, but now with the Sex Note they don't have to settle for perfection anymore! A odd experiment, but one she would be sure to like, or so he wishes.

When Ochaco is engaging in sexual activities, her breasts will start slowly filling up with milk. The more milk stored, the more her breasts become sensitive. Once full, they'll start dripping a little bit and expanding further to store more milk. Ochaco won't be able to milk herself, only other people, and milking will be extremely pleasurable. Her milk is always delicious, sweet and warm, and has a aphrodisiac effect. It will not leave any stains, disappearing after her orgasm - unless properly stored or wished otherwise - and returning her breast size to normal.

Once he puts the note and pen back down, Deku approaches Ochaco on the bed and notices she has already stripped down to only a pair of pink panties. She seems very embarrassed but also eager to continue, so that motivates Deku to climb onto the bed, take off his shorts and rest on top of her with only his boxers hiding his twitching erection, pinning her down and rubbing his crotch on her own as Ochaco spreads her legs and wraps her arms around him with a shy smile and giggle. They stare into each other's eyes, playful lust and excitement sending sparks flying when Deku lowers down and starts planting kisses along her neck. "What did you wr-ah!" Ochaco tries asking between the kisses, but is interrupted by shivers running down her spine as her body starts responding to the newly induced milk production!

"Wow... What is going on?" Deku continues kissing her upper chest, getting more and more excited as Ochaco moans louder and louder. "I'm... I'm lactating? This is... Oh my don't stop!" He licks around the areola as her stiffening nipples perk up, teasing her. Her hips buckle upwards, teasing his concealed erection. "I-izuku! Wha-ah! What have you done to meeee??" Her eyes roll back as Deku's tongue flicks and swirls around her nipples, his hands slowly pressing her firm breasts. There's a new warmth and firmness to them, a soft slushing sound coming from them and combining with the angelical voice of Ochaco.

"I hoped you'd enjoy this..." Deku slows down his licking, and starts unwrapping himself from her and lowering his head towards her crotch, where he starts planting kisses on top of the panties. "Dekuuu!!" Ochaco sings lustfully, as she starts pressing teasing her own hard nipples. Warm white milk starts slowly dripping as Ochaco screams in ecstsasy! "Oh my god Izuku, don't stop!! Ah!" Her body trembles and contorts instinctively as she works her own hands on the now growing pair of perfect tits - or rather udders - as they expand forwards full of delicious milk. "Deku! I... I cant I..." Her tone pleads Deku to help her with this new situation, but Deku decided to have some fun.

"Wait a little, Ochaco... It's gonna be worth it I promise" Deku says in between deep, savage breaths as his own excitement shows through a certain desire to be more dominant. Using his arms and a tiny bit of his Quirk, he quickly raises Ochaco and removes her panties, revealing the cute pussy hiding underneath, already soaking wet. He playfully kisses the underside of her thick soft tights - Deku loves how soft Ochaco is all around her entire body! - and she responds with louder, involuntary and syncopated moaning as her hands start pressing against her growing mounds and doing a "push and pull" movement towards her hard nipples, which were glistening with her milk very slowly trickling down. Not enough to slow down her growth which quicky approached a extra cup - likely resting at D's - and more to come.

The only question now was whether or not to let the growth continue, or have mercy and help her out.
