I may not be a "waifu," but I'd be this overworked OL's husbando without a second thought. Luna said it best: our resident heroine, despite her unfortunate circumstances, was blessed with voluptuous breasts and a robust body. I want to remove the heroine's night gown and kiss her bouncy boobs that glisten with her perspiration.
I lightly lick her nipples. Then my kisses slowly make their way down towards her stomach, where I suck on her bellybutton a little (she let out a sweet little laugh when I did that, so I could tell she enjoyed it). I firmly grabbed the heroine's beautiful butt and eagerly indulged in her fragrant and energetic vagina. It doesn't take long for the heroine to violently come, a reaction that was followed by me kissing her as she melted from pleasure.
I'm happy I was able to help her vent all her built-up stress. Her "little girl" was wet and happily rubbing against my penis. I did my best to endure by squeezing and massaging her cute chest.
In the end, we embraced and connected our crotches together. I was focused on her big boobs pressing against me and my penis comfortably imprisoned inside her. I whispered gratitude for defeating the Demon Lord in her blushing ear, and we continued to kiss and come on each other without a care in the world.
Thank you for the translation (god OLs are so cute).
