It is at least 2 years old and has sci fi/fantasy elements, although I don't recall what category it was in. A male warrior rescues an imprisoned woman (a princess?) from a castle, and as they escape, they nightly hide from pursuers in a magic portable wormhole he has. Simmering attraction grows between them. He is injured in a fight, and she tends to him, exploring his unconscious body as she rubs oil on him. They venture into some mutual exploration over the story, but don't have sex (at least in the first chapter) because he considers it dishonorable to take her virginity. I believe there was at least one follow-up chapter set in a warriors' training school. Possibly the title had the word 'portal' or 'portable' in it. Would appreciate any leads...
