Sometimes all that sub-conscious conditioning of my best friend slips out when he gets really excited and the pup he is starts taking over. Its quite embarrassing when it happens in a public place, fortunately Im not he the focus of attention. The best thing to do in such a situation is get him somewhere private and reinforce the mental triggers and push the pup back down into the sub-conscious.
And if that doesnt work I have to fuck the cum out him as soon as possible. This has lead to a few instances of sex in public toilets.
