when i lived in portland i dated a guy, jerod, who was a personal trainer and wanted to get blown by a guy in the plank position. i was happy to oblige but it took a lot of effort, holding the position, while sucking dick. i can only hold plank for 90 seconds, so it was a quick blowjob, and teethy too. but jerod was a good sport. a workout for both jaw muscles and ab muscles, yet i will always prefer 69 suckoffs to plank blowjobs. jerod later died in a horseback riding incident after being thrown from a stallion in a corporate competition in myrtle beach. rip. 2012.
