It's really hard to choose because any cock that needs to be sucked sounds delicious to me. I think 1 and 3 would be fun to play with. Kissing and licking these girls ball sacs would be heavenly-like a nice little meal or snack. Love to spank my tongue with those cute little clitties-a nice bite sized meal
Mint would be fun to test the limits of your deepthroating skills. Sliding your tongue up and down that shaft would be like sampling the world's largest lollipop! How far could that lovely cock shoot a load down your throat!
MMM...
