One bed for two: an incest story about a stepmother and stepson spending the night together

It just so happened that the hotel where the stepmother and stepson were staying only had single rooms... well, that is, rooms with one bed. They had no choice but to take what was available so they wouldn't have to sleep on their bags at the train station. One bed for two really brought them closer together. Of course, a young guy in his underwear with a bulging mound, and next to him a sexy MILF in a bathrobe... it seems this story will be labeled "incest."
