I am a man in my mid-30's named Nate. I am average build, average attractiveness. I have a large cock that is a little longer than normal and very thick. I have a co-worker named Claire. Claire is just out of high-school and is an amateur gymnast, very flexible and attractive. She has a round butt, firm legs, medium breasts, and a pretty face with wavy brown hair and a wide mouth with very thick lips. One day we are working and I ask her to help clean out the furnace closet. It's very, very tight in the room, we basically have to press against each other to both fit in. Suddenly the door slams shut and locks from the oustide. We both know it will be several hours until someone comes to let us out. With the door closed its very hot in the room. If we don't take our clothes off we will overheat and pass out. It's so tight that when we are naked, it's impossible for our bodies not to press into each other and I get easily aroused. Tell in great detail with dialogue and in the present tense
