"That would be very, very appealing to me." Istredd does like that song and now he's met Jaskier in person and he understands well how he has both Yennefer and Geralt in his pocket. If Istredd wasn't happily in love and satisfied with his currently irresistible partner, he probably would have been easily seduced by the man. He has a feeling that is common for Jaskier.

It would be strange to hear Lucifer speak Her Sweet Kiss because it's not really easy for a gender swap. But Istredd would probably be into it regardless.

Pulling away from the offer is exactly what Istredd does when Lucifer physically invites it, knowing it's an instigation. He likes getting a reaction out of Lucifer, taunting him sometimes to see how much more of one he can get. If Lucifer will lose patience. Istredd continues to provoke him that way as he now moves his mouth so that it's almost touching Lucifer's skin, his warm breath felt and the curve of his smile.

"I have never played a fiddle in my life." Istredd's tone is droll, as they're both simply joking around the song. Just speaking caresses his lips against Lucifer's neck but no more than that. He puts his hands on either side of Lucifer's head and pushes up, equally moving his body just out of reach. His weight, his heat, pulling temptingly within reach but not on him.

"Do you think you're better than me, my love?"
