Check on Kate

You head towards your sister’s room and you stop short just before her door as you see that you can see her naked in the mirror. She is toweling off her wet body, and your cock grows instantly rigid as you watch your hot big sister get ready for school. Her tits are huge, way bigger than your moms, probably almost a D-cup. You jack off thinking about your sister’s body all of the time, and now you get your first full view of naked. The hard pink nipples are small, and centered in perfectly round, small areole. She lifts her big tits and dries underneath them and then stops and looks at her body in the mirror. She teases her small, pink nipples with her fingers as she looks at her big tits, flat stomach and slim, hard ass. She knows she is prefect looking and you wish this moment would go on forever. You are rubbing your hard cock though your pants, and realize that you will cum quickly you are so excited. Then she looks in the mirror just right and sees that you are watching her.

“Jake,” she says in a surprised voice, “What are you doing?”

You feel your embarrassment rising and you head down the hall, your hard cock tenting out the front of your pants. You hear her call after you, “Wait Jake.”

You reach your room and shut the door. Your cock is pounding and stiff in your pants and you whip it out and start to jack off. You think about your sisters tits, and how tight her pussy must be and you quickly bring yourself quickly to the boiling point. Her breast looked really firm they had almost no droop to them and her small, taut nipples pointed upwards. Most of the tits you had seen in magazines hung pretty far when they were that big, not that you cared or anything. You have your eyes closed and you are picturing your sister in all kinds of sexual positions, fucking her from behind, tit fucking her, her on top riding you. You are getting so close to cumming, you can feel the tingle in your balls of the coming explosion.

Then your bedroom door flies open and your sister is standing there. She slipped some panties on, but she has just a towel in front of her big tits. She has the towel pressed against her tits, and her breasts are pushed up and form perfect half globes on her chest. You had already reached the point of no return, and you look at your sister as you begin to ejaculate. Your cup your ball sack as your cock sprays your load of cum all over the carpet of your room, and you sister watches in silence as you look at her body while cumming. The two of you stand staring at each other as you finish your orgasm until your mom’s voice yelling up the stairs breaks the silence. “You two are going to be late if you don’t get moving.”

Your sister heads quickly back to her room and you hear the door shut. You move to your dresser and get yourself dressed and head down the stairs to where your mom is fixing breakfast.
