I don't want to ruin my chances of being able to orgasm. You move down my stomach and to my pussy, I hear you chuckle. "My, what a needy little slut y...u are."I moan and fight hard to keep still while your fingers move around my wetness. Trying hard not to squirm, I plead with you. "Please, I need to cum!" But you ignore me and continue playing within my wetness. "PLEASE!" I practically scream."If you want to come, you need to ask properly." You say firmly."Please Sir. I need to cum! Please!". I then moved ontop of her and entered my cock into her wet cunt and started fucking her. I drove my cock deep and hard in and out of her puss making her moan loudly from the pleasure as she woke up. After a few minutes I pulled out and laid on my back. Jes climbed on top of me and lowered herself down onto my hard cock. She sat upright on my cock and started riding me back and forth, fucking me with passion as she moaned. Her cunt tightened around my cock as she reached climax and orgasmed.. Just the thought of touching her drove me mad. As she lay next to me under the blanket I pulled out my cock and started to jack off. I was not sure why I did this, but I figured she already saw me doing this once, what would be the difference if she caught me again. I made sure to shake the bed and made light moaning sounds to be sure she knew what I was doing. I moaned her name a few seconds after I started and that was when I saw a crack in the blanket rise. Knowing my little sister was right. Outside it was a little foggy and it was quite chilly but inside the temperatures were rising very fast. By now, she had put both her legs up on the Dash board and opened her legs to the maximum and her pussy was wide open. Anybody passing by would have seen her wide open and shaven cunt and my hard thick cock sticking out of my zipper. Can you imagine the sight ? While all this was going on, she had abandoned herself completely to the sexual passions but I could not concentrate 100% as I was.
