Smother

As Heather walked away, your sister dropped down to smother you again.

"You don't deserve to cum, big bro. All you deserve is to be smothered out cold by my ass." With all your energy depleted and feeling very horny from the footjob you were not able to offer up any resistance to the ass smother. You gave in to the inevitability of unconsciousness. Megan looked back at your face while you were fading away. "Oh I'm going to love watching you go out. This is such an empowering feeling!" The last thing you saw before going out was your sister's smug face.
