A girl that works with me is used to drink during the day from a bottle of water that leaves besides her seat. When nobody is there and the office is locked i get totally naked, i sit on her chair and i lick the bottleneck where she puts her lips, then i rub my toes (i have a foot fetishism) and my dick. To finish the job i suck my toes and jerk off, and i'm always so excited that i come in a very short time
