Last sunday my former teacher wrote me a message, asking whether I would like to come to his flat like in the old days... I agreed, because I always liked his imagination... when I arrived, he told me, that he would like to film me... In special situations... I agreed at once... I always liked to be filmed by him... He filmed me getting naked... showing my small flaccid dick... touching it, pulling back my foreskin, showing my cockhead, my small hole, jerking... Slowly I got really hard... then he got naked too... I was glad to see his very big cock again... but he wouldn't let me touch it, instead he presented a rope and tied our cocks and balls together... I got very excited by that... he started to tie our cocks even tighter, especially exactly right beneath the cock head, which was exciting... then he inserted a metal stick in both our urethras... it was hurting a bit... I think he liked that, because he started to film closer... he said he would relieve me from the stick if I would show him how I piss... I promised to, but it took me some time... he kept filming... he was still naked and hard, and when I finally pissed some drops he started touching himself and told me to open my mouth so he can make me taste his cum... he continued filming when he was cumming... than he allowed me to put on a cockring... This made me really hard and excited and he filmed me cumming from very close...
