I like to incorporate a lot of hand positions when jerking a realistic dildo, telling them to do exactly like I do. Love to lube it up to get it nice and shiny. Then a few fast strokes before telling them to flip hand upside down and stroke that way. Then use 2 hands, each one twisting in different direction. Firm grip, 2 hands, thrusting hips into it. Then sit on one hand, get it all numb so it feels like a strangers hand, while they stroke with other hand. Then use the "stranger hand". Before I know it, a lot of time has passed, so I hope these ideas help.
