For me it's pretty much just the opportunity to play with a cock and make somebody else feel so good. I'm kind of an enigma in that I'm not really into guys, but I love cocks--the hardness of the shaft but the softness of the head at the same time, the pulsing and twitching you feel during the act, the surge and flex when they come. Most of all I love that I can inspire such pleasure in someone else that they trust me enough to have something so valuable in my mouth. Looking forward to next time.
