To perform a "Wolfbang" correctly, a male must be having sex with his partner from behind and then carrys out the following actions to sucessfully complete the "Wolfbang"
A./ Quickly and unannounced the male slips his erect penis up into his partners anus and rides it vigourously
B./ At the same time the male puts his right hand forward and between his partners breasts and shoves his two fingers from the extended hand down her throat.
C./ Just as the male is about to ejaculate, he shoves his fingers further down his partners throat and when she gags on his fingers, her anus will tighten and with that, the male must howl like a wolf while he completes his ejaculation
The night was going really well for John and Mary, he was so romantic, that was until he got her home and forced her into a "Wolfbang"
This would be another variation of the already infamous Irish BullDog
