What is Sea Gull?
1.
A sexual situation where one girl and 5 guys are involved. Two of the guys DP the girl while she jerks off two others and blows the last. While this is happening, her moaning sounds like a sea gull and her jerking off motion resembles the bird's wings flapping.
"well if you really want to, I think Jill would let me, you and three other dudes give her the old sea gull."
