applying lubricant to the penis, then rubbing it slowly up and down while viewing images of attractive woman naked or engaging in sex acts. In time, the rhythmic movement will lead to a build-up in excitement. At this point, your sister and her best mate will walk in. It'll be too late to stop and a sticky whitish fluid will shoot out onto your computer screen. The girls will close the door and you will be left in a state of profound shame.
I was jacking off to pictures of Carmen Electra when the nuns walked in.

When Spider-Man rubs his wrist using his hand until a white sticky substance is released, often called, "His Webbing". Spidey often uses this "Webbing" as a form of transportation among other things in order to save the day. This is why when Spider-Man isn't horny, the day does not get saved.
Person - "Help, I'm being robbed!"

Spider-Man - "*Frantically rubs his wrist and moans* Come on you son of a bitch!"

Person - "Is he jacking off?"

When a guy slides his hand up and down slowly or really fast, however he likes it, on his hard dick until he gets that immense feeling. That feeling is one of the most desired feelings in the whole world and when it happens, you get ready to shoot your warm load all over the place.
O man. I was jacking off last night using this lubricant. It felt so good when i shot my load all over the place.
