It's hot to think about your wife letting another man cum in her mouth, isn't it? It's probably even hotter if she doesn't let you cum in her mouth, isn't it? That would make sense, wouldn’t it? The man that can actually satisfy her deserves to cum in her mouth, after all.
There's still fun to be had once she's taken his load in her mouth, though. Fun with you. With her cuckold. What kind of fun would you like to have?
She Swallows and Kisses You - This is vanilla stuff, but it can still be fun. She swallows his load and immediately kisses you, sharing the taste of another man's seed with her cuck husband, who just watched her give a blowjob or get fucked.
A Cum Kiss - She doesn't swallow. Not this time. No, instead, she kisses right after he cums in her mouth. Her tongue pushes his thick, salty seed into your mouth. She shares it with you. She shares a sexually superior man's load. She nourishes your cuckold soul in the process. You both swallow a little.
Cum Swapping - You lean your head back and open your mouth. Her mouth hovers over yours. She spits his load onto your eager, waiting tongue. She transfers all of it, gently presses on your chin until you close your mouth, and orders you to swallow. Only then are you rewarded with a kiss.
She Spits His Cum Onto Her Tits - His load spills from her mouth and onto her bare breasts. She then orders you to clean them, because of course she does. What's even better, though, is that you treat this as a generous reward from your beautiful wife, for what could be better than slowly, sensually licking and sucking the thick cum of another man from her perfect, perky breasts?
She Spits His Cum Onto Your Face - Let's get a little kinkier, shall we? She stands above you. She makes you tilt your head back. She slowly spits every drop of his hot cum onto your face, making a wondrous mess of things and making a mess of you. If she's a dirty girl she might then lick it up and kiss you with it. She might make you feed it to yourself, though, or have you wear his cum until it dries.
It Becomes Lube for a Handjob - She holds the load in her mouth for a little and then spits it into her hand and wraps her fingers around your little cuck dick. Now you're on the receiving end of the finest handjob of your life.
I'll bet you'd enjoy damn near every one of those options. I'll also bet you have ideas of your own. So, what else could she do with his cum?
