That's some damn smooth tip. Can't stop playing with it!

A little bit of shine on the tip

Love riding the tip

Massaging the tip (akebi no hana maho)

Treating the tip

Would you let me do this to the tip of your cock

Can't get past the tip

Wrapping my toes around his sensitive tip

Anybody want to come lick the precum off the tip of my big dick?

Just a tip...

working the tip of your cock till your eyes roll back

milking the tip
