Yes

You focus your willpower and take a deep breath. You can smell how wet your wife's pussy is and that almost sends you over the edge, but you're able to hold on. Your wife is lying facedown on the bed, breathing heavily. You stand up, your cock trembling.

"Can.. can I fuck you?" You ask your wife.

"Oh? Did all that finally make your prick hard? Fine, you earned it." You hurriedly place your cock at the entrance to her asshole and push. Because it is so well lubricated with your spit your cock slides in easily. You bottom out in her ass and it's so wet and so tight you cum instantly. Your cock pulses again and again, filling your wife's ass with your spunk. You oull out and collapse on top of her. She unceremoniously rolls you off of her and looks you in the eyes.

"I thought you said you were gonna fuck me." She flicks your sensitive cock. "Lucky you're so good at eating ass." She kisses your forehead. "Go to sleep honey. I'm going to have a shower."

She gets up and walks into the ensuite. You lay back on the bed, exhausted. You have no idea what tomorrow morning is going to be like.
