Sakshi while riding Gaurav was still jerking Vipin, & I could see the fluids coming out of Vipin’s cock. Vipin got up & positioned himself behind my...sister & it was in that instant that it hit me that they were going to do my sister, I wondered as to how long have they been doing this. Vipin held her still & entered her butt slowly, when he entered her from back, her body jerked & she was gasping from the pain. He slowly got into his rhythm & so did Gaurav & they stayed in that position for 6-7. I decided to wander over as she was finishing up. She stumbled a little as one of her heels sank into the ground and I smiled to myself thinking of the hazards of high heels. She looked up as I arrived, an inquiring expression on her face, but she didn't say anything."Nice outfit," I said. "That dress looks really good on you, and it fits you very well."She seemed a little surprised, either at the compliment, or that a man would know anything about women's clothing. "Thank you. I liked it as. "Maybe I should join the men's track and field team." Freddie wondered out loud.Sam laughed. "You know I love you, but you would get killed." She stopped chewing at she realized at what she had just said."What did you say?" Freddie asked."Uh, I said you would get killed." No before that." I didn't say anything before that." She avoided."Yes you did, you said you loved me." No I didn't." Yes you did." Freddie smiled."Okay I did. But if you tell a soul, I will kill you." I love you too, Princess. But my sister wanted a comparison and told me to show her or she’d make me eat my moms pubes.She said she’d show me her pussy and that she wanted to try the lube out anyway so she lay back on the bed and pulled her pants down and pulled her knees up. Her thong covered pussy was facing me and I could see she had some hair too.She told me to pull my cock out and compare it to my moms dildo.I pulled down my fly and my cock hung out as my sister looked on. She told me to stand fully naked and hold.
