Caitlin asked Barry "What's wrong?". Barry told Caitlin what happen and he had no where to sleep. Caitlin said "You know you can stay at my place". Barry said "Oh cool". .
Caitlin was finishing her work and invited Barry over.
Caitlin told Barry she was gonna go shower. Barry said "Oh ok". Caitlin started showering and Barry was watching her. The bathroom started getting fogging and cold freezing. Killer Frost started to take control and saw Barry.
Killer Frost stepped out of the shower and was looking for sex. Killer Frost walked to Barry, unzipping his pants pulling it down and started to lick his cock. Barry groan as Killer Frost kept sucking his dick faster and her lips was making Barry dick cold. Barry could feel her dick getting more cold. Killer Frost kept sucking and going deeper. Barry moan making Killer Frost go deeper.
Barry whole dick was freezing and Barry felt like cumming. Barry came hot seed in Killer Frost mouth. The hot cum started defrosting the cold in Barry dick and Killer Frost. Killer Frost sallow the cum saying "That's hot~ but not hot enough". Killer Frost started to lick Barry balls. Barry said "Whoa Caitlin calm down". Killer Frost grabbed Barry dick freezing it saying "Caitlin is gonna be gone for some time I want this to last forever!". Killer Frost pushed Barry to the bed. Killer Frost threw Barry his suit saying "Put this on I want the Flash~".
