it happened on vacation (and continued at home) pt 4
 
You can only imagine the situation. Here is my little sister bent over with her freshly fucked cunt exposed, cum dripping off her ass, running down her leg and me kneeling behind her with my dick in my hand. I couldn’t have come up with a plausible story to cover this no matter how much time I had.
The instant I heard the voice behind us, a quick jolt of terror ripped through me, I FROZE, nothing registered in my mind other than WE’RE CAUGHT !. My sister had immediately dropped down on her side pulling her blanket for cover while issuing a typical high pitched girly scream.
The world suddenly came back to me and I slowly turned my head. Standing in the doorway with a smile on her face was a girl who looked to be my sisters age.
 
 My sister yelled out WHAT ARE YOU DOING HERE !. The girl was leaning against the door continuing to smile and said “Well, I didn’t see you outside this morning so………….. GET OUT yelled sister my cutting the girl off in mid-sentence.
All I could do was stay in my kneeling position with my head turned looking at this girl. Her and I were looking at each other then she glance down at my cock then back at me and with an approving nod said “nice”.
GET OUT my sister said again. OK I’m leaving, then looking at me with a smile and a wink she said “my brother is home today to”. Upon hearing that it was like ice cold water being poured over me and within microseconds it all came together.
 
Later !, the girl said glancing in my sisters direction, JUST GO said my sister. The girl looked at me and mouth a silent “BYE”.
 
Still kneeling I turned and looked at my sister while pointing in the direction where the girl was and asked “your friend with the brother, the one you had sex with ? “.
She had her head covered with the blanket now but I could tell she was nodding yes. I finally sat back dumbfounded looking down at the bed.
Are you mad ?, came her muffled voice from under the blanket.   
No not really, I said. Pulling her head from under the blanket she asked, your really not ?. I looked straight into her eyes and with a pleasant look on my face I lightly shook my head no.
She sprang up on her knees hugging me and said “I love you, I can explain everything” all the while planting kisses all over my face while I was moving my hands down her back and over her nice plump butt.
Her kisses slowed, our eyes met and she leaned in giving me a wet passionate kiss as I squeezed her ass with both hands pulling her into me. My cock was growing stiff, she broke our kiss and looked down then looked back at me and said ” I love you”.
I got up pulling her with me and said “lets go to my room, I don’t want anymore surprises.
 
As she headed to my room I went and locked the front door (which her friend had entered through) thinking we better be more careful from now on.
