Due to a mistake at the hot spring inn I was staying at on a business trip, I ended up sharing a room with two senior female employees! We ended up sleeping side by side! Naturally, I was nervous and couldn't sleep, but my senior's sleeping posture was bad and her yukata gradually got messed up, exposing her panties and big breasts! I couldn't help but get an erection, so I thought, "I might as well rub it against her!" I rubbed my hard cock against her ass and thighs so that she wouldn't notice, but she was actually awake and excited, so she reached for my cock and I had a dream threesome with my seniors!
