suck gash
A term that refers to orally stimulating a female by simply sucking, as one would a lollipop, on her birth canal (aka vagina). One can use his/her own discretion whether or not they include the clitoris in the action or not. If the individual who is performing the gash sucking chooses to exclude the clitoris from the sucking it is recommended that said individual should manually stimulate it with their finger and/or a feather duster.
