Yonia claims she and Luna were lovers a while ago and even had sex a few times. Since Luna did do explicit g/g videos early in her career, I can believe it. In fact, I think I'd prefer to pay for a custom of them both having sex than of Yonia (or Luna) giving a titfuck.
Anyway, re Luna doing b/g, someone asked her on OF months ago (and showed his DMs as proof) whether she'd do it, and she said yes, but for a huge amount (I think $3000). However, she had the thread taken down because people kept leaking her content, so the post no longer exists. In any case, she apparently blocked the guy soon after, so she may not have been serious.
