A combination of the stranger and the reverse stranger. In the double stranger you sit on both your member and your hand, before masterbating. Then it's like you're watching someone else get a hand job... You're just a guy in the room watching.
A variation of the stranger. The act of siting on your dick until it becomes numb, and having your partner sit on her hand until it becomes numb, then she proceeds to jerk you off. This gives the illusion that you're both watching someone else give and receive a hand job.
This is a variation of the Stranger. You sit on both hands until they are numb, and masturbate with one hand while putting a finger (or more) in your ass with the other.
Person 1: Yo dawg I was home alone and feelin frisky so I gave myself the Dirty Double Stranger!
Person 2: Ewww get away from me you nasty fucker!!

To sit on both your penis and dominant hand until both are numb, then proceed to pleasure yourself. Since you've lost feeling in both, it feels like watching a person receive a handjob.
