Try convince her to have sex with you

Having been sated, Rose stood up and kissed you. The trail of cum that had been on her chin got trapped between her and your cheek. It was the first time she made you taste your own cum.
After the kiss, Rose said “Goodnight, sweetheart.”
She then turned around and crawled into the former kings bed. You had to admit it was getting late, so after you wiped the cum from your cheek you joined her.

When both of your naked bodies were under the sheets, Rose start musing.
“You know, I’ve never slept in a kings bed before.”
You took affront to this.
“Hey, you’ve slept in my bed plenty of times.”
Rose laughed. “That’s the bed of a princess, not of a king.”
Theoretically that was true, but you didn’t much enjoy it.
“But you know,” Rose continued. “The best part of this bed, is that you are in it.”
Hearing her say this made you so happy. You shifted a bit closed to her and then kissed her lips.

But not only you took notice of your lover proclaiming her love for you, your cock did as well. As it started getting hard again, your mind got filled with images of desecrating your enemy’s bed by making love to her.
“Hey Rose,” you said. “Let’s do it.”
“You know my feelings about that, John. Not until after we’re married.”
As much as you loved Rose, she could really be a pain about this.
“I know you have needs, John. That is why I’m giving you hand- boob- and blowjobs. But I want to be pure when I stand in front of the altar.”
Yes yes, this story again, and if you try to change her mind, she’ll be upset at you for not understanding her.
“I’m sorry.” You apologized. “I’ll be patient.”
Rose smiled and laid down to rest.
“What you don’t know, Rose.” You thought “Is that there is another pussy I can enjoy. Locked away high up in this castles tower. If you won’t let me enjoy yours, then I’ll just have to take hers.”
Then you too laid your head into the pillows and slept.
