If I were a better writer, I probably could have tried to express the idea a little better that Anon and Raven have been doing this for a while, only slowly edging there way towards her getting ready for the real thing.
That's what i meant by the >"Next time"
I think with Raven, you'd have to try and just slowly build up your romantic encounters with her, allowing her to get acclimated to the pace of the bedroom, and letting her get more comfortable with controlling herself during the sex. Slowly but surely, the sessions will get longer, and you'll finally be able to do the real thing.
I bet it'd be a funny little story of Anon and Raven first trying to fuck and going too far, causing massive damage to the tower, and then Anon and Raven having to explain themselves to Robin.
