When a female has to shit but cant because she is constipated
, a male fucks her in the ass so it loosens her up. When he pulls out she shit all over the mans genitals. THen the girl licks the shit off of his penis and nut sack and stomach.
Rick: dawg i got to 67th base last night.
Sam: sick dicks man, how was it?
Rick: damn good! she shit ALL over me.
