Let's do this

Well, if she could be so bold, so could he.

"Let's do this... suck my cock mommy." He sure as hell didn't call her Mommy anymore, but she started it.

Heather wasn't going to allow herself time to hesitate, and latched right onto his cock. She moved with as much vigor as her sore muscles allowed... so much so that at one point her elbow gave out and she slipped down, driving John's cock into her throat and gagging her. She fell back off his cock, coughing.

"Are you OK mom?"

"Fine, Just give me a second"

A flash of inspiration had hit Heather, and she knew how to fill the bile tube. But should she do it now and try to fill both tubes in one blowjob, or just get his cum now in case the site of her puking makes him unable to cum?
