double-dick jack-off

A double-dick jack-off is when a guy takes his own dick in his hand and and grasps it along with his JO buddie's cock, and then jacks them both off at the same time -- trying to cum at the same time so they can feel and see the cum-spasms spurt from one another's dicks at the same time.

Now and then, Matt likes to give us a double-dick jack-off!

Double Back Jimmy Jack

This is one of the most difficult sexual positions and it's approved by Dr. Falchi as "corona safe" you are back to back doing it - you have to be very flexible.

We did the double back jimmy jack last night and my legs are killing me, I need to do more yoga.
