For me it depends on the situation.
If Im pushing it out:
It's so I can record it being pushed out. I love showing off and sending videos to my regular tops to get them horny and eager for their turn. The other reason I would push out is if the top is going to catch it in their mouth, or their cock, and feed it down my mouth. That or we cum kiss with that felched load until we're both sloppy in the face.
ABSORBING IT ALL!
I prefer complete absorption. There's times huge loads were in me so long that no load could be pushed out. I prefer deep impregnation, and any leakage that occurs while I'm still taking loads, is pushed back inside, or fed to me by cock. I like going about my day and having it leak out in public, and I'm always happy to tell my top or tops that it leaked out, and how long it took even though I was deeply seeded and stretched. They're even happier when I tell them that I didn't and kept it inside for the ex boyfriend to discover
