You wake up to the all too familiar feeling of Loki's morning wood on your back. You had always found it amusing that even just sleeping next to each other and cuddling was enough to turn him on. You were about to reach over and shake him awake, but you're struck by an idea of how to wake Loki up a bit more pleasantly.
You lightly push Loki onto his back, causing him to stir a little bit, but not enough to wake him. You gently pull down his boxers, exposing his erection. You put your hands on the base of his shaft and give the head an experimental lick. You watch him but there was no reaction. You decide to kick it up a notch and run your tongue from the base to the tip, making Loki groan a little bit. You smirk at his reaction before swirling your tongue over the slit.
Your actions don't go unnoticed as Loki, still sleeping, gently moans your name and grips at the sheets. You decide to take his length into your mouth and start sucking, causing him to slowly waken. Loki doesn't notice you at first, but you release his cock from your mouth with a popping sound, causing him to look in your direction. You look into his eyes as you bring your lips to his length and start sucking again.
"I thought I was just having a dream, darling," Loki says, breathless.
You don't reply but take more of his length into your mouth, lightly nipping along the way. Loki lets out a low moan, almost a growl, and you see that he is close. He grips the sheets tightly as you suck him off. You take as much of him as you can into your mouth and quicken your pace, wanting to satisfy him.
Loki's release comes with a raspy groan, and you swallow as much of it as you can as it runs down your throat. You clean him up with a few more licks before removing yourself from in between his legs. You crawl up the bed before resting your head on Loki's chest. You don't speak for a while, just enjoying each other's company.
Finally, Loki breaks the silence and kisses the top of your head, before saying, "I love you so much, darling."
He pulls you in for a kiss before rolling over and pinning your arms over your head. You let out a gasp of surprise as you feel your wrists bound to the headboard. You look down and see Loki smirking between your legs. "Oh come on, darling, I just want to return the favor."
