“How are you going, mom?” Mia teased as she mocked her son, “Holding up well?”

“Stop calling me your mom! Being a single mother is hard enough as it is.” Evan whined, struggling behind his back to unclip the tight bra that was ill-equipped to hold up his enormous hooters. “And speaking of ‘holding up’, I don’t know how Ms. Walker was able to get through the day with this terrible cup support. My back aches and people won’t stop staring.” Finally able to unhook the clasp, his J cup breasts hung free. Softly rubbing his tender nipples, he sighed in relief.

“I definitely don’t miss those widowed parent problems from before the Great Shift. Guys have it so much easier.” Reaching between her legs, Mia could feel her cock begin to harden as her teenage libido kicked in looking at her son’s giant bare breasts. “It feels nice being young again.”

Noticing his mother begin to play with her dick, Evan scoffed. “You know we’re still related, right? You’re XXXmyXXX biological son now, so stop being so eager.”

“Funny, isn’t it?” said Mia, “All these years I spent complaining about your boyhood behavior and now XXXyou’reXXX the one in charge. I guess it’s convenient that our neighbors happened to be around the same age.” Noting her son’s disapproval she sighed, lifting her hand away from her crotch. “Well, if you’re not going to do anything about it...”

“Ugh, fine.” Evan relented, dropping to his knees and crawling over to his mom until he was eye level with her stomach. “You know the drill. I let you fuck these big titties, and in return you promise not to tell everyone you caught me masturbating in this body...” Seeing Mia nod Evan got to work as he had a dozen times before, enveloping his mom’s 6 inch member into his deep cavernous cleavage and starting to massage its length with his breasts. Bouncing them up and down against the teenage boy’s hairy crotch, he was unable to look away as his mind was unable to ignore the painful humiliation.

Minutes passed of passionate titfucking as Evan tried all sort of techniques, from alternating cycles to cupping his mom's balls with his manicured fingers to slapping the circumcised tip against his rock-hard nipple until he felt its length throb as Mia began to orgasm. Caught by surprise, he watched as the cock he was holding drenched his tits and face in an impressive amount of warm, sticky cum. “Happy now?” Evan spat unimpressed as he surveyed the damage, avoiding the satisfied gaze of his once-mother. “I don’t remember you being such a horndog before the change.”

“That was... incredible...” said Mia, heading back to her room to leave her son to clean up all the mess. “Ms. Walker's body was almost built for this. I can’t wait for next time!” Watching the door shut Evan looked down at himself, now in the body of a humiliated cum-covered MILF being blackmailed into sexual favors by her own son. He was glad that she hadn’t suggested fucking his mature pussy yet, but he knew it wasn’t far away. He only hoped that he couldn’t still get pregnant.
