Wife Little Surprise

My wife likes to tease about sex things she knows i like whether it is ass play, bj, facials, sharing whatever. She will always make a comment about something and throw in a (oh yeah i bet you'd like to do that to my ass) things like that. the other night i came up behind her while she was doing dishes in the kitchen put my hand down her pants and started rubbing her clit. she was loving it my fingers were inside she was ultra wet. we moved to the dinning room where i propped her up on a chair doing it doggy style. i grabbed both her shoulders and pounded her hard. she softly said stick a finger in, i did not hesitate i spat on her asshole and slipped in my thumb and she let out the best moan i think i have ever heard. im pounding away and i tell her im going to cum, she pulls herself forward gets off the chair and she finishes me off on her face cleaning every last drop off my cock. She got up to go to the washroom and said see i let you do things you like
