Secret Weapon

Walking out into the library Xander was pleased to see Giles had numerous books on the study table and he was taking notes. Muttering to himself the whole time as he copied down things of interest.

Willow... Xander did a double take at Willow.

His red headed best friend was standing off to the side with her blouse undone while she went about massaging her much bigger breasts. The change was very noticeable as Willow had left her modest B cups behind, her white bra discarded at her feet, and was no sporting what had to be a very large E cup. With a ridiculous smile on her face and her eyes closed in pleasure Willow ran her hands over her new boobs.

That was certainly proof of sex magic being real. And awesome.

Xander stepped to his best friend and with a devilish grin he reached out with both of his hands and tweaked Willow's now more pronounced nipples. Willow yelped and jumped back, slapping her palms flat across her nipples as she moved. Eyes popping open Willow started to glare only for that glare to falter as she took in Xander's arrival. Pulling her hands free she leaned forward and thrust her chest out towards Xander, showing off her bigger tits.

"Nice boobs."

"Thank you. They are very... sensitive." Willow beamed as she traced her fingertips up and down the slopes of her new breasts.

"No doubt. No doubt at all." Xander smirked at her, "Things going well? Learning lots of new things? Happy?" He gave her big boobs a meaningful look and mimed pinching her nipples.

"Oh yes." Willow moaned happily as she cupped her new boobs and jiggled them.

"And what about me? What have you two discovered that will help me tonight?" Xander spared a look at the silently working Giles before he returned to staring at Willow's new tits.

Willow clapped her hands and bounced in excitement"I found your secret weapon for tonights threesome."

"Oh?" Xander asked as he was enchanted by bouncing big boobies.

"I found THE secret weapon for tonight. Its a way for you to fuck Buffy and Joyce at the same time." Willow said with a smile. "Two dicks. This spell will grant you two dicks. One for Buffy. One for Joyce. Line them up right and you can do them both."

"Huh." Xander pursed his lips. "That would be... neat."

"Or you can fuck their cunts and asses at the same time." Willow leaned in and said conspiratorially, "If you wanted to take it to the next level, I can grow a dick and between you and me we can make the Summers girls air tight tonight, with a cock in every orifice."

"Interesting." Xander bobbed his head, "What else you got for me?"
