Oh, alright...I'll play too.
Ahem.
In general: dirty talk (drools..), biting, sudden changes between rough and tender, leather, home-made toys (so satisfying to use something you've made yourself).
As a dom: puppy play, spanking, tease and deny, cum control/restriction, making people beg, clothing control, breast bondage, face-slapping, choking (mmm...doggy style with a belt around the neck...-looks around for jamie, then realises he'll be at work. damn.)
As a sub: spanking (again!), body worship, tease and deny, name calling, choking.
Probably a whole lot more. But that's the basics of it.
