I do like some amateur dramatics. Plus such theatrical societies are populated with hot guys and pretty bisexual girls. Went for rehearsal one night, a play set in ancient Greece that featured numerous sex scenes. The final scene was an orgy. Director instructed me to come to the front of the stage and lay flat. Was wearing a pink mini dress with these panties underneath. Then we had to find a partner and simulate a sex act. I ended up with posh girl Sophie on top of me. I opened my legs a bit and we feigned rubbing our clits together which Sophie finished off with a big kiss. We normally all go for a coffee after but 2 volunteers are requested to stay behind and put the props away. I was selected along with Jake, tall, fit guy. We'd fancied each other for quite a while and once the gear was put away we quickly jumped in the men's toilets and devoured each other. I like the smell of men's toilets, masculine odours, images of strength etc. Jake bent me over a sink and penetrated me hard, while these little knickers descended to the floor. Afterwards we went to the coffee bar and as I sat down, could feel his sperm and my juice leaking through the pink mesh of my underwear. No one could see but it gave me a mini-orgasm. I felt dirty but triumphant. The combined liquids stained my socks as well which is why they, as well as, the panties are available.......
