I need to study this with my tongue, drop your balls into my mouth please to keep them warm and hanging loose. Then I'll examine the sequence of events with my tongue while you wank and cum
A fun part of giving a BJ is watching and feeling how his balls morph. Bring him to the edge and stop: ball sack all tight and then relaxed. I’ve edged with guys and we have marveled how big our balls got over time.
