Karen was reminded of the many guys who drooled over Sarah McMillan's breasts. She confidently used her assets to assert dominance over girls and lead on dumb boys. Karen knew Jon appreciated Sarah's looks, but he wasn't a fool; Sarah was a bitch and didn't want anything to do with her. Karen, on the other hand, was Jon's best friend. And, thanks to her accidental wish, Karen had Sarah's breasts. All it took was having the guts to show a little skin and Jon, someone even Sarah couldn't sway, was putty in her hands.
Karen absentmindedly bit her lip. The whole situation was making her excited. "Confidence!" she thought to herself. Slowly, Karen leaned forward and started running a finger lightly over the swell of her breasts, watching for Jon's reaction. She continued the show for a brief moment before exclaiming, "My eyes are up here, Jon-boy!"
This broke Jon from his trance. Her looked Karen in the eyes before lowering his head, face completely flushed.
Karen broke into a fit of giggling. She sat down on the bed next to him and gave his shoulder a shove. "You should have seen the look on your face!"
