The act of a woman putting a vibrator in both her anus and vagina simulataneously resulting in a finely tuned climax.

Fork Tuning 

The act of sounding (the practice of inserting plastic or metal rods into yours or someone else's urethra) while edging (getting seconds away from climax and stopping, waiting for a few more seconds then starting again) then when you finish your edge you take out the rods and the flood gates open.

Ian has been fork tuning so muck that he filled an entire bucket with semen
