Either the boobs or lack of air must have scrambled your brains, but you say, "I'll stay with you."
The words come out without any thought, and Laura's enthusiastic hug pulling your face back into her breasts removes any opportunity for you to change your mind.
Again, you endure the lack of air until your aunt sees fit to release you, finally dropping to the floor at her feet like a puppet with its strings cut.
Laura laughs at your display as if you're fooling around, then hauls you to your feet and begins dragging you towards her room. You slide along the floor for several feet before you manage to catch your balance, surprised at how strong your aunt is as she sweeps you along with her.

Laura smiles wildly as you hump her ass through the length of your orgasm, then slide down to the floor with shaking legs, your back up against the door.
