Hours had passed and it was completely dark by then. Our love making filled the night with sensual sounds and even the night critters had fallen silen.... Hands held hands as I bounced up and down while he pushed his cock in and out of my gripping pussy. I loved the way he was calling out my name, I loved hearing his moans and groans, it only made me want to give him more. I started to hump on his cock faster, feeling the tip of his dick touching my pelvis. It was hard and the veins were pushing. As she lay under him now he drove his cock into her like a piston in a car. Slam, slam, slam, slam, slam, slam, again and again and again he drove it into her pussy with all the fullness and length his dick had.Each time he slammed it into her the carpet they were laying on moved 2 or 3 inches. She had her legs around his body humping and humping into him as she screamed: “Harder! FUCK ME HARDER!” Like a****ls they continued to fuck each other as hard and as fast as they could make their bodies. Rebecca then proceeded to quite expertly slurp on Cyn's pussy alternating between sliding her tongue right along her slit and arsehole with little nips on her pussy lips and suckling on her clit. It didn't take long before Cyn was going bananas. She was moaning constantly and then started to gasp:"Oh fuck. Rebecca. You're going to make me cum. I can't stand this. I'm not a les. Please stop this. Oh, fuck."With that Cyn started to shake violently, dropped her legs down and clamped my sister's. There are three patents I file that day. The first, I plan on giving to the university. It is for a lithium-ion battery. Lithium-ion batteries were invented in the 1970s. The problem with them is they aren’t efficient, and they are non-rechargeable. By 1988 they are rechargeable, but they only hold a small charge, and the battery only lasts a few months before it can’t hold a charge. They are barely good enough for Compaq to sell the first laptop. The computer is OK, but the battery sucks. It.
