Mark couldn't hold his cum in any longer by the time he finished shoving his penis down your throat, causing him to fully cum both inside, and outside of you when you feel him finally pull out, and cover your entire body with eggnog flavored cum. At this point, you were deciding to get an allergy from tasting the eggnog.
'I can't believe Mark was doing this?' You think. 'Is this the same thing that happened in Halloween that Peter told me about? I should've been here to do something.' You were basically gagging on the cum that Mark forcefed you, but not all of it as your stomach was absolutely full of that stuff. All of a sudden, you notice something going on under your privates, when you find 2 longer nipples then the ones on your breasts, as they began to leak out, and the stuff around them turned them into reindeer teats.
