You ask if anyone would be interested in filling all her holes with cum, hell yeah!! Sign me up!!
I would start off by arranging with you to have a secret get together that she doesn't know about. We would dress up like rapists, with ski masks, then both hide around her house until she came home. When she got there, we would jump her and tie her up in the diaper position. You could then rape her face while I started on her lower holes, alternating first with hard fast pumps to her pussy, followed by long, deep ones to her ass, one after the other... when I was close, I would dump my load in her ass first, and plug it with a buttplug. Then I would fuck her pussy until I came in there as well.
Next I would switch the buttplug from her ass to her pussy, holding the cum in there while we let the cum from her ass out into a bottle. I would then have you add your cum to the bottle and make her drink it.
After this, we tie her up just inside the front door, and make her suck me while you go out to pick up guys from the street to bring in and fuck her. Anything added to her pussy stays in it, but anything added to her ass has to be put in a bottle.
The day would end with me and you DPing her and giving her another load each in her pussy and ass..., then pouring all of the cum from the bottle into her pussy and pulling her panties up over it, making them hold it all in.
There we go...
I would love to help you fuck and fill her.
