I pushed down into her until she hissed lightly and pressed on my stomach urging me back out. She rubbed the end of my erection up and down her body ...lit, smearing our body oils together then rolled her hips and pulled me back. I thrust into my sister several times going deeper each time until my groin bumped hers then stopped moving. She pulled her hand from between us and whispered “Hold still, let me get used to this.”My blood was beginning to boil, I was getting hot, I was shaking like a. She giggled while he looked right at me with a smirk. Later on that morning, I was sitting in the living room watching TV while mom was upstairs taking a shower in preparation for work. Ryan came over and sat right next to me in his underwear. He said, “Holy shit, your mom wore me out last night.” I just sat there watching TV and sarcastically responded with, “That’s great.” He replied, “I mean it. Your mom is one the best. Nice ass, amazing tits, tight body…” I then cut him off and said,. He responded with a brief and muffled, “Hey.” The sun was shining in my eyes so I kept them closed. His hand began to slowly move down my shoulder.All my senses now shifted from listening to being focused on his touch. I felt every inch of movement as his fingers touched my skin. Now my heart was really pounding fast. What have I gotten myself into? He slowly slid his hand across my shoulder, brushing my neck, and ever so slowly down between my breasts until he gently cupped one of my breasts.. "I can't knock you up, Elsa," he said. "I've had one of those operations." Well, let's do it!" she breathed.He stared at her very hard, his eyes flared, he slid his left arm across her shoulders and the other hand went to her bulging jersey."I could get ten years for this," he muttered. "If you ever tell--" Oh, I won't, honest!" she cried, trembling. "Not my own favorite brother!"She felt him shudder, he cupped a breast and she held her mouth up for a kiss. He took her lips the way no one ever.
