The giggling even included Babcock's fan block."A witty reply, Ms. Darling," Babcock smiled evilly. "Perhaps you will enlighten us with the answer to ...y question?" The difference between U-test and t-test, Sir, or the one about my last name?" This is statistics, Miss Darling." Oh, okay." Deirdre started, still speaking in a low voice. "The fundamental difference is that the U-test compares ranking, not numerical values. This makes it more robust against outlier data pairs but sensitive against. So we rented a room in a posh locality. Then things started like once we entered the room she said she wants to be fully satisfied tonight and asked me to fuck her till she is half dead and she was in black T shirt and blue jeans. I locked the door and hugged her from behind and started picking her neck and sucking it while my hands were busy crushing and shaking her busty boobs and my cock was hard n it was rubbing her ass over the clothes. She was moaning like aaaaahhhh come on dear fuck me. She was actually sucking the dildo that I just had had inside Cait and she could get it so deep and she was gagging and slurping and she grabbed my ass as she sucked it and she made it as wet and slippery as she could and then she stood up and took her pants off and she didn't have any panties on and she climbed on the bed so she was standing on all fours with her face over Cait's ass and Cait said “No, mom” again but she didn't sound very convincing anymore like she had given up and her mom. She loved being his slutty slave but of course around other people they treated each other with respect.By the time Kasey was done playing with her nipples she was horny for her master’s cock all over again but she would wait and have a little free time because she knew she would be fucked soon anyway.At bedtime Kasey’s pussy would be sorely used but she would still go read her 30 minutes of sex stories and shove the vibrator back in her sore pussy. It would feel so good seeing as how sensitive.
