My Wife Teases Me

So back before my wife and i use to have sex quiet a bit but now a days she is more a tease than anything. I walk by grabbing her ass or tits from behind sometimes grabbing and rubbing her c**t which she liked very much and would lead to a fuck session. Now most days if i do that i get the "could you not god". The other day just before she left for work she came up to me and said" maybe when i come home ill give you a nice head rub blowjob and you can cum on my face and tits"...see i give. wouldn't you know it i mentioned that later that night and she just made a disgusted know noise and told me to fuck off. I don't know why she even bothers to say anything if she's not going to follow through. She has changed so much i don't even know how even approach her about sex anymore. Like who says stuff like that just to tease. Sometimes i wish i could just force her to her knees throat fuck her and cover her face in cum maybe even with a hard cock slap at the end.
