Cum is the reward and yep, like you, I got a boner reading the comments.
For me swallowing a fresh load of cum is a must, I learned a long time ago to enjoy various little tricks that enhanced it for me, one favorite being for the guy to pump his load while his cock is almost out so the cum shoots over the length on my tongue, and then suck him in and finish him off. I also realised guys enjoy me enjoying the taste of their spunk so I swirl it around in my mouth before I slowly swallow so I get all the flavours.
