Something new

Lately my wife has been trying new things with me. One is she would have me kneel over her and jerk off on her tits. Doesn't sound bad but she will rub my ass with 2 fingers and just before I cum she would put them in my mouth. Ok, its my ass so if she likes it so be it, id does kinda turn me on. The other thing is I will be laying down and jerking while she is putting her fingers in my mouth. Its like she is fingering my mouth, all while she is telling me not to bite and how to suck them at the same time. When I cum she will just swirl the fingers in the cum and then rub them on my lips. She hasn't fed me the whole load yet but I wonder what she is up to.
I admit I do like it.
