I'm standing in line at the bank with my friend Jenny, a tall, leggy brunette with long curly brown hair and a fun, goofy personality. I'm married, but Jenny and I regularly flirt in a harmless way, knowing nothing will ever happen. Today we're in for a shock. The bank is taken over by robbers and we are held hostage. They forces us to strip naked and tie us together, with Jenny sitting in my lap. It's terrifying, but also undeniably arousing and I feel myself getting hard. WIth no way to break contact with Jenny, I get more and more turned on until I accidentally slip inside her. Tell with creative prose, dialogue, and detail. Tell in present tense.
