She shifted, and thrust one thigh between his legs, and lifted it up, pressing into him. He groaned again, a low sensual sound. She felt it all the wa... down inside. Her strong hands kneaded his firm ass while her thigh continued to push against his cock. He opened his eyes, and looked down into her face. ‘God, she was beautiful,’ he thought. Her cheeks were flushed tan, her mouth open slightly, her chest rising and falling gently. Looking up at him, she began to unbutton her silk blouse,. “It’s testosterone,” I corrected. “i’ll remember that.” My sister began to giggle. “My big brother is helping me with my sex homework.” “Better me than another boy.”You sure are jealous, aren’t you? “With a sister as beautiful as you I need to be jealous, and vigilant.”“No you don’t, but thanks anyway,” my beautiful sister said while affectionately squeezing and pulling on my now “squishy” penis. Then she rubbed my stomach. “You have such a nice washboard stomach. Every boy has genitals, but. Report to me in your bedroom. And Gail, be naked and have your cock sized dildo in your ass. I want an easy entry to your bottom after I give you a severe whipping with my belt." I detected a faint smile on Gail's face as she left the kitchen to comply with my instructions.When she returned she was in compliance with my orders. Her shiny nude body had two inches of a large rubber cock like appliance sticking out from her stretched brown hole. I was naked also with my erection standing out. I seen my mom is laying on bed with her both legs wide apart having a candle in one hand her panty was removed and laying on bed her one hand on her own boobs I was got stunned by seeing that all she also noticed my presence suddenly and covered herself I turned back and came in hall.sat on sofa all picture was moving in my mind whole flat was moving around me cause my mom is very strict she don’t like dirtiness vulgarity I started to think what is this I was total blank in that time after some.
