After our staff Christmas party, the librarian and I stuck off to my classroom, while very drunk. She was dressed up as Velma from Scooby Doo. She started riding me on my desk and asked if I cared if she watched some porn, turned out it was uncensored, Japanese, lesbian tentacle porn, with massive loads of fake cum shooting everywhere. She was riding me harder and harder so I just let her keep going. She asked if she could use a toy, at this point I didn't care, she was ginding so hard, next thing I know there's a double ended dildo going in both out butts, very new experience, but I was drunk and went with it. After a bit more grinding and her watching her porn, I gave her a cream pie, which she proceeded to push directly into my mouth while she sucked and licked me clean. We haven't spoken much since, but every time I see her, she taps her handbag and winks at me.
