You notice a tingle starting at your crotch working its way up making you even more aroused, you feel your cock slipping back inside and you panic "No no, please, I'll do anything!"
Duke seemed to be fishing for that kind of response all allong and said "Anything, huh? Well, How about that dark haired guy that comes over sometimes."
"What dark haired guy?!" you say and feel the change continuing.
"The one that comes over and sits on the couch watching some sort of game on tv with you."
"Do you mean Mitch? And thats football we are watching." You say
Duke nodds and says "Yes,, he pushes me away when you're not looking, I'd like to teach him a lesson."
"What do I do?!" you begg
Duke shruggs "It's really quite simple, bring him here and get him to put on the collar, I'll take it from there."
