Her Odd Request

I travel a lot for work and my coworker and I missed our flight and couldn't get another until tomorrow. We went and got a hotel, rooms side by side and went and then went and ate dinner. On the walk back she asked if I'd do her an odd favor and swear to never tell anyone else. I was hesitant but said OK. She asked if I could take some adult pictures for her. I agreed, but there is something about this woman you need to understand, she is not smoking hot. Shes about 40, really tall skinny blond with strong Germanic features. Not ugly, but not a super model either. I'm a short , 5'7" stalky guy and she at least 6'1".
We got back to the hotel, she stripped bare, skinny but cute ass, small tits, big pokey nipple, trimmed blonde bush, long pussy lips. I took the pictures, spread her and positioned her as I did, and was hard as rock the entire time. After about 30-40 pictures she asked if I would jerk off and cum on her. She made it very clear she didn't want to fuck, but said if I came on her it would make better pictures. So I did, rubbed her skinny ass and wet pussy as I jacked off and blew my load on her face, in her mouth, and on her little tits. I took more pictures as she stroked my half hard cock with her giantess hands. The final picture she wanted was licking up the small amount of cum she squeezed out of my cock.
She got in the shower, I'm back in my room wondering what the hell just happened, and I have no idea what she plans to do with the pictures.
