Searching a comic with ex hitman

I’m not 100% sure it was a yiff comic but I remember the story starting at a park bench. The male protagonist gets kidnapped and wakes up straped down on a table. The kidnapper gets revealed as an ex hitman (mafia?). The hitman tells the protagonist that he wont kill agan but found new way to punish his victims. The protagonist gets tortured with a device so he climaxes over and over again. The hitman leaves him over the night on the table overstimulating him constantly. I think the protagonist wakes up again on the park bench.
