I only wear panties when my gf weard them home from a fuck date with her 10 inch bull.
They're quite a mess from him filling her pussy with cum.
Often she'll wrap them around my 5 inch cock and jerk me off with his cum.
Sometimes she makes me wait until tomorrow to cum in them. If she does, she has me wear her "cummy panties" all day b4 she lets me cum.
