NO. I basically was like, "and then they went and had sex while Eleven was flailing, and that was why Clara was willing to sing Hungry Like the Wolf later" but, uh, I think David Warner could read the phone book, and I'd belike "and then they done sex!"

(or possibly not sex. I don't know, that's just what my brain jumps to)

Also, it's not like the professor is older than Eleven, or anything, and people ship Clara/Eleven (and Rose/Doctor, and all the companions/all the doctors). So it's not like age is even an issue. Also, Clara doesn't seem like she would care.

(all this to justify porn without plot. heh)
