Counterattack!

You spring up towards Heather with all your strength. She let's out a cute little squeal of surprise as you slam her back onto the floor, once again on top. Both of you are breathing heavily now and your head is swimming. You risk a glance around and see that several of the circular lines on the floor have disappeared under the encroaching pink mist.

Staring down at your opponent you can tell that the gas and her orgasm have affected her. You still see some white liquid seeping from the head of her still erect cock which twitches with her every breath.
