A soft jerk is the act of jerking off with a flacid(soft) penis. A soft jerk usually begins when someone fails to cum a second time while attempting to jerk off one more time before their penis goes soft, but they’re in too deep to stop now.

A soft jerk can be frustrating because it feels like you’ll never reach the end even after a solid 10 minutes of trying. Eventually your arm will probably get tired and you’ll start to feel extremely hot, this is the critical point where you decide whether to just give up and push through the pain to your final orgasm.

The orgasm resulting from a soft jerk usually doesn’t feel like it was worth it at all, with the orgasm being short and the feeling very muted. Chances are you’ll feel extremely tired after a soft jerk and wish to take a nap. For this reason, soft jerks are best done at night before bed so that you don’t have to worry about not having energy enough to go about your day.
Person: Fuck. I wanted to cum again before my dick went soft but I couldn’t make it. I’m in too deep now, best try and do a quick soft jerk

10 minutes later

Person: it’s been 10 minutes and nothing... what the hell?! My arm is getting tired

10 more minutes later

Person: It’s coming!... well that was disappointing. I feel like taking a nap now...
