"Yes baby," he replied.
She saw how hard her dirty talk was making him, and thought this must be a CNC type fantasy for men - that he really liked. "By the way, now that I have peed on you, you are mine forever."
When she was done relieving herself, Sara got the shower head and rinsed Blake off, then started washing her butthole in front of him.
"There is one more thing I want you to do, I'm am going to bend over and I want you to lick my butthole, and let me rub it on you while I pleasure myself." She went to grab her vibrator before they started, then she bent over in his face and he started enthusiastically kissing her butt and licking her right between her cheeks. "I didn't know you were going to kiss me there too, even better!" She giggled. First, she just used her fingers to play with her clit, then when that wasn't enough, she used her favorite setting on the shower head and directed it to her pussy to pleasure herself. As she got more excited, she started grinding her butthole on his face as she promised.
"I wish you could feel how wet this was making me, but you are only allowed to touch my butt" she teased. When she was ready to come she picked up her vibrator. She held it against her clit and started breathing more quickly and softly moaning. She came from the stimulation she was receiving all at once, and when she did, she relaxed and let his tongue a little deeper into her butt, which felt like heaven as she was climaxing.
When they were done cleaning up and getting ready for bed Sara teased Blake "you were a good little slut tonight" She kneed softly between his the legs one more time and wiggled her butt at him. "Since you did so well, you can do whatever you want to me tomorrow, so save your cum for then. It will be cute to have you horny for me all day tomorrow at our wedding." And with that, Blake fell asleep to thinking about all the dirty things he would do to her the next day.
