We have a new sex doll but my chastity sub has a locked cock and isn’t coming out of his cage! So with his cock out of action it’s a real struggle to fuck it properly but I made him try anyway with the help of some other toys, firstly a cock sleeve, then a strap-on dildo all while his wrists are shackled behind his back. Since he would be attempting to thrust in and out of a fake pussy on the doll I thought I would make his balls swing some more by attaching some ball weights. For some extra fun I gave him a little chastity challenge  which I kind of knew would prove difficult! He had just 60 seconds to thrust in and out of the sex doll 100 times and if/when he fails I add a further 1 month to his already long chastity sentence.
