"Let's make Mei older!" Frank suggests, ordering Mei to stand up in front of them.
"How old do you want me to be?" Mei asks with a giggle. Ty orders her to take off her clothes so that they won't be ripped during the change, seeing her happily strip away her clothing made him even harder than before.
"Old enough to be my mother. Let's go with 40 years old and with a thicc body." He says, and soon she started to progress with age. Mei's height immediately shot up to six feet, towering over the boys now. Her hips grew with her rear being very large, and her breasts grew till they were a solid double K cup. A small patch of pubic hair grew above her pussy folds, and last her thighs became really thick just for Frank.
"Wow!" Mei exclaims with joy, squishing her huge breasts together. "This new body feels so amazing! Thank you so much!"
"C-can you help us with our erections?" Frank scoots over to the side of the couch as well as Ty, making enough room for Mei to sit right in the middle between the two.
"You boys are so cute~" Mei takes their cocks in each hand, stroking both of them at the same pace. "Mommy will take extra care of you."
"Th-thanks Mei-" Ty groans out as she strokes him. "I mean..mom.."
"Mmmm yes call me mom now.."Mei gasps when feeling one of her nipples being suckled on, glancing down to see Frank's small head smothering against her huge breast. "O-oh yes~ Suck mommy's tit, little one."
Ty had more height than the younger boy, going for Mei's mouth instead of her titty. The make out felt very passionate and blissful, never having felt so safe and warm in his life. Their tongues twirl around one another's, Ty's hand groping her unoccupied breast very firmly to make the older woman moan in his mouth. Mei stops stroking them for a quick moment to spit in each hand, going back to jacking off the boys even faster. The younger boy's moans were muffled into Mei's breast, squeezing it with both hands to try to get any milk out of it, only to suckle even harder to hear another moan from the woman. Ty goes back to making out with Mei, his hand now moving between her thick thighs to feel her very wet pussy folds.
Frank was the first to cum, moaning into her tit and bucking his hips as he shoots out a few strings of jizz into the air and landing onto her lap as the rest covers her hand. Ty and Mei both moan into each other's mouth as his orgasm comes as well, shooting 5 strings of cum onto her lap and covering her hand. They break the kiss and both the boys lick the cum off of her for cleanup, making the older woman giggle with a cute moan to follow.
"Th-thank you, mommy." Frank lays his head on her thigh, Ty laying his on the other.
"I love you two so much! I can't wait to do more fun things as your new mommy." Mei pats both their heads, feeling extra horny from pleasuring the two.
