The dog panted heavily from exertion, his rhythmic breathing a metronome for the fast and frantic timing of this interspecies tryst. The fetid stink of pig did nothing to dissuade the bully's thick, engorged penis from its orgasmic twitching, glistening with preputial lubricant as shot after shot of virile sperm splashed upon the mucky ground. Foamy boar drool slowly trickled down his shoulder as the lustful hog lunged and lurched on his back.

The dog changed his stance to support the overbearing weight, testicles swinging wild and low from the summer day's oppressive heat, and tail now flagged even further up and to the side to lay bare his crude approximation of a sow's vagina. The repositioning drove anew the boar's lust, corkscrew tip twisting about and around the dog's anus in frenzied desire for a tight, interlocking coupling. Copious amounts of pig semen spewed forth like from a faucet and oozed lewdly down the bully's backside.

The boar hit his mark, his penis twisting just the right amount to open up the bully's proffered sphincter and drill through. A brief escape of air from the dog's rectum announced the penetration, and in another second the boar was several inches inside, rolling rapidly against the bully's prostate. The dog shivered in ecstasy and clenched tightly around the pig's drillbit, sperm already bubbling out from the bully's bowels to dribble around the thin, pink shaft. But the moment of prostatic bliss fled as the boar sank deeper, embarking fully on his quest to plug each dank and dirtied corner of canine colon with his liters of turbid seed... sealing up the dog for days.
