As Sarah scrolled through the list of fetishes on the Chronivac, and she found one that read 'lactation'. She remembered that her boyfriend, Jeff, was already into lactation; he had tried sucking her breasts before, but to no avail. She decided to make herself into lactation too, so she could see things from Jeff's perspective.
As she hit apply, visions of milky breasts filled her mind. She imagined feeding her boyfriend from her leaking tits, which were larger than in reality. She closed her eyes, rubbing her pussy as she groped her own tits, as if she was trying to milk them. Jeff entered the room again, finding his girlfriend on her knees, with her hand down her panties.
'Jeff, can you try sucking my titties again?' Sarah asked. Jeff's cock became hard.
'I thought you'd never ask,' Jeff happily replied. He lifted her shirt over her head, exposing her beautiful boobs. He placed his mouth on her right breast, making her moan as he licked her hardening nipple. Jeff sucked and sucked, but again, no milk left her breast.
While her boyfriend was latched onto her breast, she went to the Chronivac again, altering her body. She made her boobs larger, and made them lactate uncontrollably. When she hit apply, Jeff felt his face being pushed away from his girlfriend's chest. He opened his eyes, finding his girlfriend's tits to be much larger than they were before.
Suddenly, his mouth filled with milk, startling him slightly as he tried swallowing. Jeff took his mouth off her nipple for a moment, smiling at his girlfriend as a drop of milk ran down his lip. He hungrily attached his mouth to her lactating tit, filling his stomach with his girlfriend's sweet milk, not even stopping to breathe. Sarah moaned as she watched her boyfriend use her to feed himself. She loved the feeling of milk leaving her breasts.
Sarah began to finger her pussy, and Jeff began to stroke his hardening cock while still guzzling her milk. Finally, he climaxed, shooting cum onto her stomach. He released her fat breast, now satisfied. Despite Jeff no longer drinking from her ample bosom, her teats continued to dribble white liquid. They were showing no signs of stopping either; Sarah realized she would need to buy a nursing bra, the thought of which made her even hornier. Feeding her boyfriend felt amazing, she thought; she was glad to have given herself this fetish.
Sarah continued to masturbate as Jeff thought of what to change next. Regardless, he was certain that Sarah would keep lactating for the foreseeable future; neither of them wanted this to stop.
