What Emma and Jeff did not know was that the party was at the house of a boy named Jake who had gotten his own Chronivac and as the party was going on down stares he had gone up to his room to use it to make the party better. Jake had opened up the stats of everyone at the party to make it so no-one would notice anything out of the ordinary.
When he had made his changes he closed down the Chronivac and went down to enjoy the party.
----------------------------
In the pool Jeff felt her body tingle but the only thing that she could think of was that she wanted to kiss Emma again.
Jeff and Emma started kissing again and neither of them noticed Jeff's breasts grow two cup sizes bigger, to what are now DD-cups. The bikini top did not get any tighter because Emma had undid the strings of the top.
The increase in their libidos was so much that when they broke the kiss nether of them paid any attention to the bikini bra as it fell into the water.
As they caught their breath they did feel that something was off but put it aside as they started kissing again.
The next time they broke the kiss Jeff whispered into Emma's ear "I need you in me, right now."
