Hi guys, obviously I'm here because I'm a fan of big cocks. I have regular fuck buddies and partners but I've generally always been the top, but I do have versatile desires. A current fuck buddy of mine is also a top. He is hung with 8.5-9 super-thick uncut veiny inches with a big head. We've been wanking and giving each other head for a while. I can hardly get my mouth around it though, and my jaws ache afterwards...but in a good way. Anyway, he is begging me to let him fuck me. I like and trust him, and have decided to relent....he doesn't know it yet though. But it's been a very long time since I've been fucked (about 10 years), although I've been happy to let guys finger and play with my hole. But never by such as giant cock. I'm worried that he's going to tear me apart if I let him. But the rationale side of me, as mostly an experienced top, knows this won't be the case if we communicate and use patience and plenty of lube. The shoe is on the other foot for me now, as a potential bottom. I'm excited and scared at the same time. Any encouragement or tips on bottoming for a big one are welcomed.
