A beefy tough nut may be completely straight on the outside but once doors slam shut and theyre locked up they do an about-face and start fucking guys up the arse for an easy life. Puching a cock up a fellow robbers arse is all well and good as long as they can live with themselves afterwards. The prison officers must be vigilant to make sure they control feelings that theyve done something dirty and wrong. As long as they clean their dick afterwards they usually think nothing more about it.
