Licking, sucking, taking one and then both in your mouth.  Soft, gentle and wet is really nice. Cupping them and stroking them, gently, with your fingernails is very arousing  I have been able to cum by this alone.  This is a great question because, IMO, some of the ladies don't realize how much of a turn on ball play is.

In one word.......

YES!!!

One Word!!!

OFTEN, and yes the right touch at the right time at the right spot will increase orgasm.

Personally as long as the balls are beyond super clean (a nice shower when you arrive at my incall will insure that) and I do prefer shaved...I am in there!!!  Just don't expect roughness...I am too gentle of a person for that.  For sure no rimming...nah just not for me.

But I sure love licking, sucking and teasing them balls while stroking a hard stiff one!!

Great question, great post.  I really only like them lightly flicked with the tongue and definitely not squeezed or sucked on hard.  Of course the reverse is true for Mr. Johnson.  He likes just about everything except biting.  This is just my preference, I am sure there will be a variety of responses.  Again, great post.

how about a vibrator caressing your balls as i lick and suck and tongue-massage your shaft?  it might just send you through the roof, darlin...

Play with mine with your feet, especially using a sexy pedicure on them and light kicking!
