Younger Sister Anna

Your eyes wander up the legs at your door until they take note of a very conservative skirt, followed by a very loose sweatshirt, and finally to the face of your younger sister, Anna. While Paige was known to be bitchy and hormonal, and you considered yourself cold and rational, your mother's other daughter tended to be emotional and artsy. Her sensitivity to the world was what lead you to giving her a way to open your door, even when you had locked it; a decision you were majorly regretting at the moment.

"Uh, Anna I can expl-" you barely manage to **** those words out between pants before Anna had walked across the room and begun handling your quickly re-hardening erection. You cursed your supernatural libido before once again trying to communicate with your sister.

"Anna, what are-" And again she surprises the words out of your mouth by hiking up her long skirt, slipping her panties to the side, and dropping all the way down to the seat of the chair. As you must have, she immediate starts to bounce up and down on the chair, rolling it every which way due to the wheels. The feeling of a warm pussy on your cock passes over you for the second time in your life, and you do your best to hold off as long as possible.

From your angle on the ground, you can see Anna's face as she moves her hips. From the added friction you didn't experience when you were fucking yourself, and the tears running down her cheeks, you don't think she's having as much fun as you had. When you make eye contact, she shoots you a look of such disdain and hatred that you are stunned out of all other feelings. For all your lives Anna had looked up to you as her cool older sister, and that one look cut more deeply than any knife ever could.

You need to come to your sense now; not for yourself, but for her sake. You reach down and try to tug the ring off, and struggle a bit from the fluids on the ring and the base of your cock. You managed to start sliding the accursed thing off just as you felt your climax approaching again. You had gotten the ring to just underneath your head when you started to blow. Rushing to pull it all the way off, the ring caught on your head, as your fingers slipped off of it. Gravity brought the ring all the way back down, and all the way into Anna's cunt as you released nearly everything you had left.

Out of the corner of your eye, you saw Anna fall all the way back down onto the chair, and squirm as she felt your hot load enter her. Spurt after spurt leaves your exhausted body to join with your sister's. It takes much less time than either of your earlier orgasms to find yourself out of gas. Before you can even comprehend what is going on anymore, Anna has left the room, slamming the door on her way out, and you find yourself alone, in a mixed puddle of juices.
