when your fucking a chick doggy against the wall & you pull out & stick it up her arse without warning & her arms & legs wave around menacingly like a gecko
'you should have seen my chick do the gecko last night after i stuck my dick in her arse without notice...she tried to scramble up the wall like a gecko'
