Miranda smiled humming to herself as she looked at the chronivac and Jeff's profile deciding she would give him a nice large pair of breasts and to make things a bit more interesting a Harpy Pussy. He would still be mostly male just with the minor alterations. He could get pregnant but only if she chose to let him get pregnant otherwise any time he had sex it would simply lead to unfertilized eggs.
Humming to herself she adjusted the settings and switched the reality settings so everyone but her and Jeff would think this was the way things had always been and that there was nothing out of the ordinary, giggling she hit enter she had to admit she had another reason for doing this to her son but that one was a bit more personal she was eager to test her new cock out and what better way than her son's new pussy? The best part was he wouldn't fight her too hard on it he would already be horny and wanting to be fucked so he could start laying eggs. Quickly remembering that she only changed things so that everyone else would remember her son as having a harpy's pussy and breasts she went back in to change one more thing. Her son would have a high sex drive and want to be fucked almost constantly he would be seeking out her or her husband for sex only they were in a threesome with one another, everyone would accept this as the new reality including Jeff he would be entirely fine with all the changes made to him.
Jeff was Slightly confused as he felt a tingling centered around his chest and his cock which slowly began to vanish as his chest ballooned out into a nice large pair of D-Cup breasts a bit stunned he touched them and moaned at the sensitivity not realizing his cock was almost completely gone now he had nothing down there until suddenly the skin split open to reveal his brand new gaping pussy which was already wet and ready to be fucked. The boy turned partial girl looked at his mother with hazy last filled eyes as she licked her lips before suddenly lunging at him almost and kissing him immediately her tounge demanding entrance as he parted his lips to let her in returning the kiss not noticing she was stripping him.
Miranda only broke off the kiss to tug her own clothes off the rest of the way leading them to the bedroom and pushing her son onto the bed as she entered him in one swift move causing him to wince before moaning loudly as the pain became pleasure almost immediately "Please... please fuck me mom! Give me eggs!"
Miranda laughed and kissed him again as she started to set a steady pace going in and out of his tight wet pussy "Mmmmm of course sweetie..."
Jeff gasped as she suddenly took one of his nipples in her mouth and started to lick and suck it before gently biting it causing him to moan and arch up a bit
Miranda smirked and decided to move to the other nipple she was still in her son the entire time while she lavished his new breasts with attention almost keeping Jeff gave a loud cry as he came for the first time from his pussy his mother getting even harder as she fucked her son a bit more desperately until she stilled and started to cum in him unloading torrents of sperm into him causing him to moan as he felt her cum enter him before they both lay back panting a bit but smiling satisfied Miranda still in her son turned partial girl.
Jeff kissed his mother once more completely happy and satisfied "mmmm thank you mom..."
Miranda giggled "Mmm you're welcome sweetie although you'll be laying your first eggs soon now that you've been fucked."
Jeff laughed "Mmmm I'm actually kinda looking forward to it... I've been waiting years for this."
Miranda smiled amused quite pleased with how things had turned out "I'm glad sweetheart now get some rest." The two lovers fell asleep Jeff waking up a few hours later blinking at his large stomach "Well I didn't expect this..."
Miranda blinked "Neither did I really but I think you look perfect like this. All fucked and full of eggs..." she slowly started to tease him by going on and out of him making him moan again whimpering slightly "M-mom..."
Miranda smirked "Yes?"
Jeff groaned "Please...please fuck me mom!"
Miranda grinned as she started to go in and out of him once more "With pleasure!" The two started another round of sex until Jeff lay back exhausted wincing a bit as he felt the eggs shift in him before spreading his legs "Mmm I think I'm about to start laying mom..."
Miranda smiled "Good! I'm going to go downstairs and make some food I'll be back to check on you in a while. Not bothering to put clothes on she hummed to herself as she went down the stairs changing her son had worked marvelously maybe she should change her daughter next? Or should she just keep things as they were for now?
