Got caught wanking naked in my office late one evening by two colleagues who returned unexpectedly. To keep my "dirty little secret" they made me suck them both off. They were both in their twenties, both straight and married, and one of them had an extremely large cock - a pleasant surprise! The big-cocked guy became a regular FWB and I sucked him off many more times. For the less-endowed guy, just that once was enough - he'd satisfied a long-held curiosity.
