Mama bird is the act of regurgitating semen into another person's mouth.
I bet those two Mama bird each other when one misses out on giving the foreman a BJ.
When a girl finishes a blow job in her mouth and pretends she has swallowed his cum and goes in for a kiss. To his surprise she instead “feeds” the guys cum back to his mouth.
Jessica finished off Ross and thought she was being so thoughtful and gave him back his semen via the mama bird surprise
When you get a blow job but the girl comes up and throws up to feed your baby dick
