I mention this because just last night I was treated to what just might be the absolute best ball licking Dee's ever given me. It was an ordinary evening by all measures - one of our plain vanilla sex evenings at home (Our date with Mike and Don was cancelled because of the snow and ice we had here yesterday.) and I wasn't expecting anything beyond the usual excellent time that Dee and I have together. When Dee wrapped her fingers around my cock and put her tongue to my sac, though, I nearly hit the ceiling so delicious were the amazing sensations I felt which for some reason were positively and maddeningly, wonderfully so beyond the typical very good ones.
I stopped her after a little while to ask what she was doing, telling her that I'd like to do the same thing to Mike when we see him - hopefully tomorrow here on our own bed. She took my hand and demonstrated on the back of it with the tip of her tongue what she was doing on my balls. It all seemed so ordinary, but I knew what I was feeling down there and I quickly urged her head back down between my outspread legs for more. I could barely pull myself away to slip my dick up into her pussy, but that's where I most love to cum and she was extra juicy for me.
I don't know if I'll be able to duplicate those sensations for Mike tomorrow, but you can bet that I'll knock myself out trying.
