Have you ever watched a friend masturbate to orgasm

Yeah, I watched a work colleague/friend masturbate. It was funny actually we would talk sometimes on the phone, as friends, I thought. Now and again though she would go quiet and I'd think she was bored but she's would say carry on keep talking....turned out she loved my voice and would play with herself while we were on the phone. After she confessed I said I would like to watch. She came over to mine the next weekend, it was awkward as we were both quite shy. After a few drinks she said, let's do this and just laid on the bed and pulled her skirt up, she wasn't wearing anything underneath. She was the first back girl I had seen naked in real life and I loved the contrast of her pink inner pussy lips against her brown skin. She was shaking from adrenaline and it was one of the hottest things ever to me. I got closer and closer not wanting to put her off, I sat on the bottom of the bed and after a couple of minutes she dug her heel into my back, signalling it was ok to get closer. I put my face close enough to smell her and it was amazing. I could tell she wanted me to see her make herself cum, so I didn't try and lick her, but I made sure she could feel my breath on her pussy. She started to tense and rub herself faster and she said really fast and breathless "2 fingers in", so I shoved two fingers inside her soaking wet but really tight pussy and she came really hard almost immediately.
