With Sally and Zoe completely destructed by Sally's massive feet it was all too easy to continue to use the remote on the two 'sisters'
First he selected Zoe's mouth and increased its size by and sensitivity by x10! Zoe's lips swelled to the size of bed pillow hanging off her face and overtaking her nose, almost obscuring her eyes! As she kissed and licked Sally's soles thick globs of drool and saliva plopped into the floor as her new mouth managed to open wide enough now to suck on one of the tantalizing toes. For good measure she added an oral fixation to Zoe, ensuring that if she wasn't kissing toes, she would be sucking her own giant thumb!
Next up was Sally. She did little more but recline on her hands with her feet outstretched for her MILF bodied sister to worship. So Calvin decided to give her a huge butt to sit on and enjoy. He selected her butt cheeks, anus, and pussy increasing their size 5 times!
Sally in Zoe's teenage body had been wearing a dress up to this point, and she continued to do so, only now the hem of the dress began to stretch and curl up her shapely legs as her ass cheeks and waist expanded from the growth! Each cheek lifted her off the ground by two feet as the fat supple ass reached beach ball proportions. A brown puckered anus also became visible between the hyper ass cheeks, looking like a foot wide doughnut. Her swelling vagina also made an appearance between her widening legs, the plump folds now big enough to protrude half a foot forward from her crotch and easly take a whole arm within their embrace glistened with moisture as the inner labia bloomed in size from Sally's obvious arousel, still moaning from the massive soft and sloppy kissing each toe was reserving from Zoe. Suddenly remembering the fixation he'd bestowed upon Zoe, Calvin thought it only fair that he also add something to Sally. After a moment he decided what better way to complement such a huge ass then with a mild spanking fetish!
Sally in her very pear shaped body gently pushed her sister off her feet, with some effort and only long enough to reposition herself. She stood up to show turn around, giving Calvin a show of the three foot butt shelf he'd given her, pushing her dress up to look more like a tube top. She then on her giant feet fell to her knees with her ass in the air, in fact the smooth round heel of her carseat sized feet sank up into the soft squishy ass fat, her huge brown pucker now on display as she leaned forward in a jack-o-pose.
"Go on sis, I've me a slap with those huge catchers-mitts of yours!" Sally encouraged, giving her huge couch sized ass a shake in the air.
Zoe still drilling from her plump hanging lips have a half draw of her ginormous hand and slapped the thicc slab of ass meat with a resounding clap! Sally cried out in pleasure and from her fat puffy pussy Calvin saw a squirt of girl cum sprits from within it plump folds! Sally had just orgasimed from having her ass clapped! Maybe he'd set the sensitivity to high? No matter, she seemed to be enjoying it anyhow.
With Sally appeased for the moment Zoe went back to their warship of Sally's giant feet. Getting on her own knees and massaging them with their huge thumbs, smearing Sally's girl cum across their soles and kissing the perfect curved heels, occasionally lifting her fat lips to kiss and suckle the ass that rested upon them with a resounding "plop" much to Sally's enjoyment.
Watching his girlfriends body warp so obscenely and his mother absolutely enslaved to that warped body was to much. Calvin suddenly became very aware of a dampness in his pants and saw a small stain in his crotch as his rock hard cock was dripping with pre in his jeans. He find a seat in the living room with a decent view and absentmindedly pulled down his pants and started to jerk off to the show before him.
Zoe saw this at one point and her eyes being the only thing visible of her face behind the huge lips gave what could have been a scowl between kissing and licking Sally's feet. She moved her mouth and gave a labored muffled shout before going back to her foot-service. Calvin couldn't make it out, but Sally did!
"What! Moms jerking off to us?" She shouted before gasping from a suckling kiss to her ass. "That's so gross!" She shouted before stealing a glance at him.
Calvin acting fast and hit the reality alter button and Sally's face went from shock and disgust to seductive smirk.
"Let us knew if you have any requests mom~ were happy to put on a show" Sally said then blew her a kiss. Zoe likewise said said something but was little more them a mumble in a clearly seductive tone followed by a wink.
'I could get used to this' thought Calvin, jerking off with one hand, and thumbing the remote in the other, contemplating more changes...
