Cumvulsion

The act of having a convulsion like reaction immediately after having an orgasm. This usually means the orgasm was very very good.

After the orgasm, I began to have a cumvulsion as my body twitched and jerked uncontrollably.

cumvulse

to cum so hard that your whole body convulses.

Dinesh cumvulsed so hard when he and Wendy 69-ed that he fell off his red couch.

cumvulsions

That blissfull moment during a bj when you start to orgasm and the girl starts sucking harder and your head and legs start involuntary shaking.

You start cumvulsions like your dick is licking a nine volt battery.
