A girl lays on a bed legs spread, vigorously double fisting her vagina, while a guy stands at the far corner of the room and he is bending over. He places his hands on his head thus imitating the dorsal fin of a shark. He charges forward toward his pray and plows that pussy into oblivion with his head creating the image of the elusive hammerhead shark.
Wow my vagina hurts. WHY? My boyfriend hammerheaded me several times yesterday.
