Now redressed and enjoying each other's company, Ty was helping Eileen prepare dinner. Occasionally she would bump him with her ass or flash her cleavage, and in turn Ty would give her a zap of pleasure with his power. They were both hopelessly turned on giggling as 17 year old Rebecca came through the door and tossed her car keys on the nearby table.
"Hey, Mama!" Becca called, throwing down her jacket. "Something smells good!"
Every bit as beautiful as her mother, though lacking such an outrageous chest, Becca was none the less a sweet and polite girl who had treated Ty well.
"Honey, we have company!" Eileen said as she bent down to grab a casserole dish from the oven, purposely shaking her ass for Ty.
"Oh, hey!" Becca cried. "Ty! Wow!" She approached him and threw her arms around him in a warm embrace. "It's nice to see you! Welcome!"
"Yeah!" Ty smiled, almost blushing. "Your mom has been treating me very well!"
"Oh, that's nice!" Becca said. "What are we having?"
"It's scalloped potatoes and roast, darling," Eileen said, grabbing plates from the cupboard and catching Ty's gaze with a smirk.
Ty looked back to Becca, who had taken the seat across the table, and watched her click away at her phone. He smirked as he willed her breasts to grow very very slowly and looked back to the table trying not to laugh. She jolted, looked up from her texting in surprise, and looked back to her screen without incident.
Supper was delicious. Becca and Eileen together were delightful, playfully telling stories in an attempt to embarass each other in front of Ty. Conversation turned to Ty, his family, and how nice it was that he had a break today.
Ty could only wonder what Mark and June were doing right now. He smirked as he pictured how angry they were going to be when they got back and found him gone. No matter. He would deal with them.
By the end of supper Becca's smallish bust had subtly filled out to the point it was starting to get a little more prominant, and she found herself adjusting her shirt as it slowly pulled tight around her chest. At that point, just because he could, Ty looked over to Eileen and willed her already huge breasts to start growing too. She jolted, looked over to Ty in alarm, and blushed.
They began playing a fun board game. Eileen had noticed her blouse and bra felt tighter and looked over at Ty nervously as she realized her cleavage was even more ample. Becca, meanwhile, had noticed something was amiss, as she was expanding too slowly to really perceive, but when she leaned over the table to roll some dice she noticed she was very swollen. After her turn she had sheepishly excused herself to go to the bathroom.
"I see what you're doing, mister." Eileen whispered once they were alone, cupping her boobs and squeezing them together, almost popping out of her shirt. "Me, I don't mind, but Bec is going to get freaked out."
"Didn't you want a threesome earlier?" Ty said offered, almost laughing.
"Hey!" Eileen admonished with a finger. "Make her stop."
"Fine." Ty sighed and giggled. He willed Becca's chest to stop growing.
When she returned to the table she was wearing a looser shirt and no bra. "Uh, spilled water on myself." She blushed warmly, and the game resumed.
Ty, of course, let Eileen keep growing. By the end of the game she was squeezed tight in her bra and her cleavage pressed out the top of her shirt and almost touched her chin. Becca hadn't really noticed, since she was too preoccupied about her own boobs having grown.
They said good night to Ty, who finally stopped Eileen's growth with a playful grin, which she returned, and on the way out she leaned down once Becca was gone and gave him a long passionate kiss. "You'd better be willing to play with these monsters next time I see you."
"Oh, I will." Ty grinned. "Thank you for everything today..."
"Yes." Eileen blushed. "We won't discuss today. I got a little... wild."
"Call me daddy." Ty said, and waved happily as he left the house with Eileen's mouth hanging agape.
"Sir, you are encouragible." She said, waved sweetly, and closed the door.
