when a woman is giving a man head, we all know that she gets warning before we blow a load. in this case you dont give so much of verbal warning, but a kick of the leg and make the sound of a barn animal (mine was a horse). As she looks to see what is going on, shoot her in the face.
when i made it up, i was on my futon laying down. i always told it was coming but decided it was time for change. so i brayed like a horse and kicked my leg. she looked up and said "what the..." and splat, i shot her face. the BARNYARD BLAST was born
