Willow tests some new products

Buffy and Dawn stood in front of their bedroom mirror and tried to decide on what to wear. Each one wore nothing but matching thigh-high boots as they searched thru the closet.

Their search was interrupted when Willow barged into the room carrying a small bag. Willow was dressed in a flimsy nighty that barely contained her new DD tits and a pair of high heels.

“There you two are I’ve been looking every where for you. Come over here and sit on the bed. I need you two for something.”

The two sisters looked at each other and sat side-by-side on the bed. “What’s the. . “

“matter Willow? What do. . .”

“you need us for?”

Willow smiled and pulled a small bottle and a simple paintbrush from her bag. She dipped the brush in the bottle and painted a small swirl around each one of Buffy and Dawn’s nipples.

“Tara said that if I test one more of our tit growth potions on myself she wouldn’t let me go and collect ingredients with her and Amy anymore. So I thought that I’d just test them on you two and have you pay me for the privilege.”

Buffy and Dawn looked at each other for a few seconds before they felt it. The swirls Willow had painted on seemed to spin for a moment then vanished beneath their skin. Both girls fell back and moaned as they felt a tickly sensation inside their breasts. When it stopped they sat up and inspected their slightly larger tits.

“Why only an inch. . .”

“bigger? Why not. . .”

“make them like yours?”

Willow smirked and pulled two 9-inch strap-ons out of her bag.

“If I gave you tits like mine right off the bat I wouldn’t be able to collect any payment. Now if you two can fuck me hard enough, I’ll bring the next batch here when it’s ready.”

Both sisters smirked and they took the strap-ons from Willow.
