When your partner vomits semen on you immediately post fellatio. This inadvertent return of semen is usually caused by the taste of the seminal fluid, the receiving partner having mental block to swallowing or the giving partner hitting a gag reflex.
I had to change clothes after Sally had an inadvertent return after I came in her mouth. She puked all over my stomach and lap.
