Are you ready for your next Guided Masturbation Assignment?
Double Trouble Head Stroking::

Lay on your bed.  Prop yourself up and think about what really turns you on.  Now, hold your cock and point it away from you.  Apply your favorite lubricant all over your cock and stroke.  Also, put your lube on your index finger of your free hand.  How, take that finger and twirl around the head slowly.   Keep stroking with one hand and twirling the head with the other.  Keep on doing this until you get close to orgasm.   I want you to definately try this out a lot.  Do some denial damnit.  Stroke until you get to the edge and do not orgasm.

I hope that this drives you crazy.  Remember, I own your cock!
