A//B//O #lucemond (🕊️❌, 18 +, gr00ming) AU where Rhaenyra uses Luke’s guilt to secure Aemond’s allegiance.
.
Rhaenyra accidentally bumps into a sexually frustrated A!Aemond. His rut is nearing and Aemond can’t get it off. Then Rhaenyra offers her son O!Luke to help with the rut.

Aemond is quite shocked that Rhaenyra is willing to set him up with Luke, whom Aemond definitely finds hot. However, Aemond can’t get over the eye incident and rejects Rhaenyra’s offer.

A few days later, Aemond locks himself up in his room and tries to endure a horrible rut.

He thinks he’s going insane from the rut. His knot is bulging and cannot release — Aemond thinks it’s going to explode.

Then Rhaenyra leads Lucerys into Aemond’s room. Upon seeing the terrible pain his uncle is enduring, Lucerys starts taking off his clothes.

Aemond pushes his visitors away and curses at Lucerys’ “whorishness”. Rhaenyra reiterated that Luke is here to help. “Luke,” she urges. Lucerys slowly approaches his uncle and hugs him with his naked body from behind. Lucerys asks Aemond to fuck him.

“Please uncle, for the eye. Let Luke ease your pain. Fuck me, Aemond. Please, take your rut out on me,”
Luke says. Aemond turns around and finally loses himself to his instincts. He lays Luke down on the bed and takes out his cock, aiming it at Luke’s hole.

Lucerys, since it’s his first time, whispers to Rhaenyra, “Mommy, I’m scared.” Rhaenyra kisses his hair and tells him he’s going to be a great little wife for his uncle and, “Remember how much you wanted this, Luke. How you begged me to engage you to your uncle.”

Rhaenyra knows that having Vhagar on the green’s side is going to be detrimental for her road to becoming queen. Fortunately, her son Luke is an omega. After the eye incident, Luke starts having nightmares and wants to make it up to Aemond.

Rhaenyra tells Luke that an apologize probably won’t be enough. And Luke’s asks what will. She answers that an alpha like Aemond will one day want to good omega wife, inspiring Luke to become a good omega wife. Rhaenyra holds Luke to very high standards, including 🛏️ skills.

So now Rhaenyra presses Luke’s legs to his chest to make more room for Aemond. Luke grabs onto his legs as Aemond rams into him.
[…]
When they have finished, Rhaenyra lets luke know how much of a good boy he was. A month later, Viserys I announces Luke’s engagement to Aemond.

When the two officially marry, Lucerys is heavy with child and gives birth soon after. Rhaenyra rejoices in her favorite son bringing a grandchild into her life. Furthermore, her status as heir to the Iron Throne is further secured with the Lucemond wedding.
