I opened the door, which was not locked, and saw Rita sitting in the bed, looking surprised to see me. I asked what was going on; I just saw some guy come out of our room? BTW, she was naked, and the bed was in a wild state.
She explained that she had gone to our room and, after closing the door, noticed that the lock was broken. She didn't think anything of it since she thought that I would come to bed shortly. She got undressed and climbed into bed. After a few minutes, the door opened, and thinking it was me, she didn't look. The guy went to the bathroom, and Rita still thought it was me and said, come to bed already. She heard him undressing, and he climbed into the bed. She had her back to him and snuggled up to him as he made himself comfortable next to her. After a few minutes of him feeling Rita's big tits and probing her pussy, she started to realize that something was different. She thought I was more energetic than usual but turned her on, and she turned on her back and spread her legs. Since it was dark, she still didn't see that it wasn't me. She was really getting turned on and spreading her legs further. She told him to fuck her already, and he climbed on top of her and put his cock in her dripping pussy. Then she realized that it wasn't me since he was much larger than me, so that she really could feel the difference in her pussy. But she was really horny, and even though she knew that it was wrong, she didn't want him to stop, and she just continued to fuck him. And fuck him she did, she told me that he was rock hard and pumped her like a rabbit. After she came once, Rita normally needs a pause, and if I don't cum with her, she asks me to hurry up. With him, she couldn't tell him to stop or hurry up, so she decided to fuck him harder to get him to cum. This must-have turned him on more because he grabbed Rita and flipped her on her stomach, and started to fuck her doggy style, grabbing her hips and pulling her onto his long-hard cock.
