Laying there, watching, your penis throbbing inside the steel prison in which it’s been kept locked without the slightest bit of relief for the last 2 months, while you watch your beautiful wife who you love with all your heart, slowly and leisurely suckle your best friend’s cock, taking his hard member into her hot, wet mouth, wrapping her soft lips around his shaft, and then sliding the tight ring of her lips up and down the length of his shaft, your wife’s tongue gently caressing your best friend’s frenum and glans, and working him slowly to a state of full arousal, not pleasuring him with the intent to make him cum - that would happen in due course - but rather simply for the purpose of giving him the ultimate pleasure of your wife’s mouth while you watch - your own penis not having had the pleasure of her mouth for longer than you can recall.
Before he’d arrived, she reminded you that it had all been your own doing. It was almost a distant memory, those years ago, when you begged her to do it - to lock you up, to tease you, and to deny you. At the time, it had just seemed like a wonderful kinky sex game to play with your wife. You’d been the jealous sort and had never intended for her to sleep with another man, much less your own best friend. But, with time, as you grew deeper into chastity, the truth became inevitable. She isn’t in chastity. You are. She never agreed to be denied. But you did. Eventually, to your own surprise, you began to fantasize about your wife cuckolding you, and a part of you even began wanting it to happen. At first, it was just an inkling of a thought as you watched a cuckolding video and imagined it being your wife. When you began having that same fantasy more and more, you eventually realized the truth. You were a different person than you used to be. You weren’t jealous and possessive, at least not like you used to be. You were a new man with a new need. You needed other men to enjoy your wife’s body before your very eyes, while she denied you even the slightest relief. Your chastity would not be complete until you saw your wife satisfy another man with her body.
Then, without warning, it seemed to just happen. The three of you were at the bar, and when you emerged from the restroom, her hand was massaging his thigh. Then she’d suggested you all back to your house and continue drinking there. But you quickly realized it wasn’t you and your buddy hanging out, your wife with you. Your wife and your best friend had nothing but eyes for each other, and you found yourself feeling like the one out of place as their flirtation became so obvious as to make everyone feel awkward. Then she’d glanced at you, and then pressed her body against him as her mouth met his.
Soon, your wife was sucking your best friend’s cock, getting him good and hard while you watched. Then she’d laid back on the couch, spreading her legs wide to reveal her smoothly shaven snatch and lack of panties. Your wife had guided your best friend to her, and he’d plunged his cock deep into your wife’s vagina. Then they’d fucked like animals, grunting and groaning and moaning, until eventually your wife came, the spams of her pussy clamping down around your best friend’s cock pushing him over the edge. Then, he came inside your wife.
When he moved in, it only made sense for him to be the one sleeping in the master bed with her. After all, he was the one fucking her all night long.
