What My Wife Wants

Lately my wife has this obsession with watching me suck cock. It started about a year ago, we were playing this truth game and I confessed that in my late teens I allowed a stranger suck my cock for money. She was really excited about it and ever since has been pushing. Not long after the game she started with blow jobs then french kissing me and asking how it tasted. I played along and things escalated. It wasn't long before I was eating her out after ejaculating in her, the blow jobs have now become cum kisses too. I have a big dick and she has got me to self suck and now she won't allow me to stop until I cum in my mouth. I've learnt how to swallow under her guidance and last night she wanked me off into a bowl and then pegged me whilst I lapped up my spunk. After I cleaned the bowl she told me she'd got a guy in mind whilst she fucked me hard doggystyle. Well these games are I suppose acceptable in the marital home between consenting adults but to bring another male in doesn't sit well especially for gay sex for my wife's pleasure. I have always given in to my beautiful wife for fear she'll leave. Has anyone any idea's?
