To say I was shocked was a major understatement. There I was laying on the bed my face between my sister's thighs while she ate out her best friend, Michelle's pussy as Michelle sucked my cock. That wasn't the part that shocked me, even though it would have 2 days ago. The thing that shocked me was that my parents were standing in the doorway looking at us enjoy each other on their bed. They were supposed to be on a week-long second honeymoon and it was only day two.
I quickly dove for the thin sheet and tried to cover myself up but had no success with the 2 teenage girls laying on them.
"Mom, Dad, what are you doing home," Ashley squealed.
Mom only laughed. She was apparently not angry at the situation in front of her.
"Well there is a bad storm in the Bahamas so we decided to come home and spend some time with our kids. But it looks like our kids are a little busy," she said.
Our parents were certainly dressed for vacation. I slowly took in the whole situation around me. Dad was wearing a t-shirt and a pair of khaki shorts but it was mom that took all my focus. There she was standing in the doorway with a big smile on her face in one of the smallest sundresses I had ever seen. Her long smooth legs were on full display as the dress fell to just mid-thigh. I found myself wondering how I couldn't see her panties. My eyes slowly moved up the floral print dress and fell on the deep v between her full breasts. She looked braless and a little larger than Ashley; I guessed a large C cup probably.
I took in mom's beautiful face that looked like it belonged to a 30 year old not a woman who was in her 40's. Her long blond hair was pulled back in a loose ponytail. I truly admired my mother for the first time until I felt Michelle move from beside me. I looked over and watched her walk completely naked up to my dad who was smiling at her.
"Welcome home, sir," she said.
Michelle didn't wait for a reply before sliding her arms around my dad's neck and kissing him passionately. Their tongues were quickly exploring one another's mouth. I watched my dad's hands reach around and cup Michelle's firm little ass; the same ass I had just been running my own hands over not 10 minutes earlier. I was in mental overload at this point and wondering what I didn't know. I wondered why mom wasn't yelling at them. Then I realized mom wasn't even standing next to dad anymore.
I then looked over to see my sister sitting on the edge of the bed her legs spread and mom standing between them kissing her daughter deeply. I was amazed as I watched her kiss our mom with a mouth that had just been cleaning out Michelle's pussy. Her lips must have been covered with my cum and Michelle's sweet juices. Their hands were roaming over each other as they kissed like long time lovers. It was the sexiest thing I had ever seen and my cock, which had grown soft, was quickly growing back to full strength. I must have had an extremely confused look on my face because when my mom looked at me she laughed playfully.
"Oh honey, you have some catching up to do," she said with a sexy grin.
I just sat there not knowing what to say but my mom seemed to know exactly what was going through my head. She smiled at me knowingly as she spoke to Ashley.
"Honey, why don't you and Michelle keep your dad busy while I get your brother up to speed."
Ashley giggled and kissed mom again before sliding off the bed. My eyes followed her body as she moved over to dad, kissing him just like Michele had. I then realized that Michelle was below Ashley and already had my dad's hard cock between her lips. I was in disbelief at this point as I felt mom put her hand on my cheek and turn my face to hers.
Mom had the sweetest most caring smile on her face and I couldn't help but smile back at her as she said, "How are you doing honey?"
I opened my mouth but no words came out. There was just too much going on in my head to put into words at this point. Mom once again seemed to understand and laughed sweetly.
"What I'm thinking is you've spent the last 2 days fucking your sexy sister and her sexy little friend. I'm sure you're doing great." This comment brought a little bigger smile to my face; amazed that mom wasn't going crazy right now.
Mom softly placed her hand on my bare thigh which sent shock waves through my cock making my cock tense up even more.
"Well I suppose it's time you found out about all of this," mom said watching my reaction.
