Diega is such a slut for swallowing cum (Video and GIFs in comments) - She strokes his dick until he starts squirting then buries it in her throat until her lips touch the hilt.
The Lola Megapost (A fuckload more in the comments.): She strokes the cum into her mouth and sucks the tip to swallow it all. She then buries the relaxed cock down her throat and licks his balls.
Haley strokes until the cum shoots her in the face. She continues to suck, stroke, and deep throat. When he tries to back out of the glory hole, she pulls him right back in and sucks on the tip.
