I'm baby sitting my sisters cat and my sister is late. Finally, she walks in through the door and apologizes for not getting back sooner.

Although the apology is accepted, you mention that you did have things to do and she could have called. She gives you a look you have not seen before, not one of anger or one of "I said sorry".

Her eyes were almost pleading and her mouth was open ever so slightly. With a slight tremor in her voice she says, Hold on, I'll be a minute, and walks into her bedroom and shuts the door. Well, it was almost three minutes, (but that's what women do) before I heard her call out saying "Could you come here and help me with something please?" I was in a bit of a rush but what the heck, I'm here anyway and yeah, she is my sister.

I've never been in her bedroom before while she was in it. I've have snooped around when she wasn't home and checked out her lingerie in the dirty laundry hamper and yeah, I took more than a few good whiffs while yanking my meat. I've also cum on a few of her panties after smelling them, making sure to burry them deep in her hamper after. I've gone through her drawers and found a few sex toys, one of them still carrying the aroma of cunt juice. Hmmm, she must have used it just before I got to her place that time.

I must have been day dreaming because she called a second time saying "have you left already?" Nooo, I'm still here, I was distracted by the cat is all. (not so far from the truth really)

I walk up to her bedroom door, knock to make sure it's ok to enter and with a slightly nervous but anxious voice, she says "it's open, come in.

I gently push the door open (which wasn't completely closed anyway) and look around absent mindedly not knowing what she wanted done.

There, on her bed is my naked sister. She's laying on her side, knees bent into a loose fetal position, two of her fingers running ever so slowly between the lips of her obviously wet and glistening cunt.

Being her brother, I should have turned quickly around and walked out of her bedroom before saying ANYTHING, but I just stood there and stared, speechless, eyes bulging and mouth open.

Finally, with a voice that was clearly nervous, but also amused she said something to break the awkwardness. "Brother, no, Honey, I know you have been wanting this for a long time now". As she says that, her two fingers reach even deeper into her cunt and she gives out a slight aroused gasp.

Then she continues by saying, " I have also been needing this, I have been wanting us to do this since we were young kids and we experimented, but never continued. I regret that sooo much."

Saying that, she seductively roll onto her back, lifted and spreads her legs. With a smile that showed slight nervousness and complete and total arousal she says "What are you waiting for ........
