Your Sister's Vibrator

Thinking back on the toy you pilfered from your sister's room, you think that now might be the perfect opportunity to put it to good use. You shut your door and search your covers for the dildo. You take a closer look at it and see that it is covered in ridges and bumps; they must be there to help stimulate its user. You search it for some kind of on-off switch, and finally discover that the ring near the base rotates, controlling vibrations with a few different settings: off, soft, hard, and pulsing.

Deciding to start with soft for now, you lay down on your bed -- still naked -- and place the tip at your entrance. Slipping it inside, you notice that you're much wetter and slicker than you were before. Rather than having it catch at your opening like Alex's cock had, it slid in deep with one push. You hold it inside, letting the vibrations tickle your clitoris. You try turning up the speed to hard, and it sends waves of pleasure through your little nub. You pull the toy halfway out of yourself, then push it back in slowly. You revel in the sensations as you start to plunge it into yourself slightly faster; you feel every bump and every ridge as it brushes past your inner walls.

You feel your orgasm approaching, and you speed up until your hand can't move any faster. You fuck yourself roughly with the dildo in your hand, allowing yourself to melt into the sensations. As your body begins to tense, you shove the shaft in deep and hold it in place, grinding your hips as it vibrates your very core. You hear the front door open and shut right as you go over the edge, forcing you to stifle back the moan that is fighting to escape you. Your body is wracked with your orgasm as you hear the footfalls climbing the stairs. You're still deep in the throes of your orgasm as whoever it is gets to the top of the stairs.
