Soft-peen-goo describes the discharged ejaculate from a non-erect penis. This happens when a male becomes so excited and turned on that before there is a chance to become hard and erect he blows his load.
She was about to give him a blow-job but, before she get get her lips around it a stream of soft-peen-goo shot right into her eye.
