With My Pussy.

You know from personal experience that a dick cums much easier than a pussy. You hope logic is on you side as you flip your leg around to mount Heather. She refuses to let you escape the gas and holds you close so you're face to face. You're both covered in the gas, though still very visible to the cameras. This is about pure endurance now.

You feel her cock pressing against yours and between your stomachs. With a little wriggling you line up with it and start to swallow it up. Heather grits her teeth, her eyes closed in concentration. She works with you now to push you further onto her cock. It takes longer than you think it should. Did she get longer while you weren't looking? Holy shit, that is deep!

Your vision goes a bit fuzzy as she starts to rock back and forth, the head of her dick rubbing your insides like it's looking for a way out.

Something you hadn't accounted for was your own cock. Now that it's stuck between the two of you the rocking motion, however slight, is getting it rubbed between the two of you.

'Not good...'

You shake in orgasm while she sighs and fills you with cum. Before you're even finished she starts shaking you in an up and down motion. You cry out and try to fight but have no strength left. Heather bites you're neck like a beast laying her claim and it sets you off again. The short thrusting/rubbing motion does the job and you produce a sticky paste between the two of you. She repeats this milking process a few times before she finally rolls off of you.

The last thing you remember before falling asleep is feeling cum leaking out of you and seeing Heather stand over you, looking like she was about to fall over, but triumphant none the less.
