Fir wo meri sister ke room me agaya. Meri sister apne cupboard se kuch nikal rhi thi to maine apne dost ko ishara kiya ki start kar jaldi or maine handycam on kar diya.Fir mera dost chupke se uske peeche khada ho gaya or achanak se uske boobs dabane laga. Meri sister ne usse chhudane ki koshish kari to mere dost ne use. Do you understand cunt?”“Yes, Ma’am,” cried Tracy.“And, if you lose count, you get it doubled later on,” said Christina.Then both girls said, “Are you ready little one?”“Yyyyyyeeeessssssss, Mistresses,” stuttered Tracy.The first blow hit her left cheek with a loud, SMACK! “One, thank you MistressChristina, may I have another,” cried Tracy.SMACK, came the next one to her right cheek. “One, thank you Mistress Linda, may I have another!” she cried again.Another loud SMACK to her left cheek! “Two,. ” I thought, and I quickly threw the g-string back into the drawer and closed it. I high-tailed it back to my room and closed the door. I grabbed my laptop and pretended to be working on homework. Then I remembered… I left the white cotton hip-huggers on her bed. “Shit,” I thought. Just as I was afraid of, I heard a knock on the door. “Come in.” I said, trying not to sound nervous. “Hey Alex,” she said as she stepped just into the doorway, “Welcome home.” “Thanks,” I said, and tried to act. That caused a shiver, and I helped her stand. I walked to her room with her and helped her to her bed, then kissed her on the forehead and said good night.After that day, Jeff continued to come over, but did nothing sexual with me. He flirted a little, but nothing that would have been out of place if we were both wearing clothes. But of course, I wasn't. I was still determined not to go as far as sex, but I took pains to brush up against him, present my tits in his face and wiggle my ass in his.
