Here's an idea. 2 weeks should be prepaid for his stay in some skanky hot sheets motel. The spreader bar stays on 24/7 for 2 weeks straight. A friend of the fortress, a beefy fella, with friends in low places, keeps watch, sometimes in the room, making sure no 'irreversible' harm comes to him.
Over the course of the 2 weeks, every skanky ho in the area is given the oportunity to use the room, gratis. Of course, spreader-boy stays, and is subject to the noises and smells of nasty low life boinking. Needless to say, the sheets are NOT to be changed too often during those 2 weeks.
For an extra $50 each john has the option to do the act on top of 'spreader boy' with the 'point of entry' right above 'spreader boy''s face. A surprising # of Johns jump at the opportunity. Day in day out he witnesses these girls ply their trade just inches above him. We won't even talk about the 'spillage'
