He stays outside the room for a moment to recollect

Steve was still wobbly on his legs so he stood outside the room for a bit to regain some strength.

E: "Shit...now I am horny..." Steve heard Elena say all of a sudden.

This of course sparked his interest. He did not want to interfere and therefor only peaked inside the room. The first thing he saw was his cum leaking out of her, so she quickly grabbed a tissue to wipe her asshole as clean as possible. Meanwhile Franzi got back up from her bed again.

F: "Then get on the bed" she said while getting up to retrieve her bottoms.

Once she was finished and looked back on the bed, she found a bottomless Elena on her bed with her legs spread.

F: "No, get on all fours!" she commanded forcefully.

Steve was surprised. The wording of the third rule was supposed to lean towards the person that was in need of relief, but it seemed as though it depended on the person. After what happened before, Franzi asserted herself as the dominant one. And judging by Elena complying to her request, she became the submissive one.

Elena got up on all fours and Franzi sat next to her. Then with out any foreplay and rather roughly she pushed her index finger into Elena's pussy. Elena, caught off guard by the rough treatment, yelped at the first push. It was obvious from the beginning that this was definitely not the best way to get Elena off, but Franzi hardly cared and Elena, at least for the moment, was too timid to say anything. Franzi eventually used her other hand to grab her phone. It looked like she was writing a text while pushing a second finger up Elena's snatch.

That reminded Steve to get his own cellphone out of his bathrobe pocket. He took a couple of pictures before leaving them alone. As he walked towards the bathroom, he went through the pictures. Elena on all fours on the bed with Franzi pushing two fingers inside of her, while mostly focused on her phone. It almost seemed like Franzi was petting an annoying needy dog just to get rid of it. That one was going to be his new computer background.
