“Of course,” her mom said. “When can you take care of it?”“Tomorrow, after work, say 6PM,” I said.“Ok,” Aimee said. “I’ll come ov...r to your place after practice.”We then went to dinner and all had a good time. I couldn’t help but to notice how cute Aimee was and so grown up now. It was like talking with an adult during the whole conversation and many times both her mom and dad reminded us all that she was now an adult and had to make her own decisions regarding many things. I never looked at. Vicky was told to wear the Naughty-Nurse outfit to school the next day, Friday, which was the last day of their pledge week. Vic was instructed to wear one last pair of his sister's panties under his jeans.That night, the twins did their assignments as usual. Vicky shaved her brother's balls etc. and give him a blow job. But this night they decided to practice their fucking technique too, they might need it in their community work on Friday. It was 2 a.m. before the twins got to sleep in each. Before you reach the point of no return I stop, I circle your head with my tongue getting it nice and wet before putting just my finger and thumb around your head. I gently rub it back and forth, watching you squirm in frustration as I deny your orgasm.You then demand I get on all fours, I quickly comply. You dive in and start lapping away at my ass hole. I try to wiggle from you but it is useless. Between the torturous lashes of your tongue you breathe “stop fighting and just enjoy it,” and. "BITCH.... I'M GONNA FUCK YOU UP...ANNIE...FUCCCCK... UNFASTEN ME...NOW...I SWEAR!" she screams.I jump up and dodge her kicks, giving her thigh an almighty slap, then another."HOW DARE YOU DO THAT TO THAT POOR GIRL!" I scream back, "YOU'VE NO RIGHT, THAT WAS JUST FUCKING NASTY!" dodging her kicking legs again, smacking where I can."ARRRR IT'S ALL YOUR FUCKING FAULT ANNIE, YOU WAS OUT WITH ME....ME....NOT THAT LITTLE FUCKING WHORE!" I am by her waist now, she is kicking up and high, trying to.
