This setup would be intense both in terms of stimulation and exercise. I don’t think I’d be able to cum quickly but I would be very turned on. I’m not sure how long I would last being tormented in this way but I might be there for a few hours trying to get off if it was really difficult to keep my cock on top of the vibrator there. I would probably take some time to rest and be subjected to whipping and spikes because my arms and balls would get tired eventually. I’d beg for mercy if I wasn’t able to cum but I might be able to cum quickly. I’ll definitely cum quickly watching the video for this session!
