I love orally servicing my boyfriend. I can do it for hours. He's super thick --- and has a huge mushroom head. (6" girth at the base and goes up to 6.5" at the head.) Shape is like a baseball bat. When I deepthroat him, it's hard to keep my back molars from scraping him slightly. That makes deep-throating less enjoyable for him so I usually just suck on the top half of his dick and stroke the rest. I'd like for him to be able to throat fuck me without the worry of teeth scraping. I don't see how it's possible without detaching my jaw or using some sort of a tooth guard. Does anyone have any tips on how to prevent tooth scrape on a very thick dick. Thanks!
