If I crawl fast with good form I get the hitachi, if I don't - first I get my anal hook pulled on, and then for safety reasons, the clip is clamped to my nipple to shut off the treadmill
Got turned into a Gag-Stool recently! Sir had me chose between getting my throat fucked and getting my ass fucked with a massive dildo. Sometimes he did both at the same time and I came with his cock buried in my throat!
