This story is pure fantasy. All characters are at least 18 years old. Reading Part 1 is not necessary but recommended due to some specific details.
The next day after Kayla's party, Kayla contacted me asking me to come over. She said her parents weren't going to be home till the next day. I thought to myself, I have another opportunity to be with a very hot 18 year old girl that wants to have sex. I couldn't resist. I told her I needed to take care of a few things before meeting. She told me to come over at 12:00 noon, she said she'll be laying out by the pool and for me to meet her there.
After taking care of my errands, I took a shower and headed over to my friend's house to meet Kayla. I walked through the side gate to get to the backyard and the pool. I announced myself as I rounded the corner of the house, "Kayla, it's me Ken coming in."
Kayla responded, "I'm here, come on back."
As I turned the corner, to my surprise I saw Kayla laying out with one of her friend's. In a bit of shock, I thought to myself, I guess we're not having any sex today.
As I approached them, Kayla introduced us, "Ken, this is my friend Olivia, Olivia this is Ken, a friend of our family."
I said, "Hello Olivia, it is very nice to meet you." And shook her hand.
The two of them were wearing string bikinis that barely covered anything. Olivia got up and said she was going for dip into the pool to cool off. As she walked by me, she smiled, as I stared at her sexy body. She knew I was glued to her body as she strutted by. She slowly stepped into the pool looking back at us.
I asked Kayla, "Is she a classmate of yours?"
She answered, "Yes, we had a few classes together and we were both on the volleyball team."
Olivia was tall just like Kayla. She stood 5'10" tall, measuring 35B - 25 - 35? Weighing 130 lbs.? She had dark brown hair that covered her shoulders, blue eyes, a super cute face and a bit darker complexion than Kayla.
I discreetly asked Kayla, "I thought you invited me over so that we would have sex, did I totally mis-read you?"
Kayla whispered back, "Oh no, you were right on that assumption."
I said, "It'll be difficult with Olivia here." As I chuckled.
Kayla looked at me with a smile and said, "I'm going to tell you something that no one else knows."
I said, "Okay, go ahead."
She said, "Olivia and I have had sex with each other. We have played around for the last year or so. I told her about you and I and what happened yesterday."
I said, "Oh my god Kayla, that was supposed to be our deep secret that no one was to know about."
She said, "I know, I know, I hope you're not mad. Here's the thing, when I told Olivia about us, she got turned on and asked if she could be a part of it."
Very startled, I said, "Oh no, here go, this is crossing into extremely dangerous waters. I would be in very serious trouble if anyone found out, besides is Olivia 18 yet?"
Kayla said, "Yes, Olivia turned 18 last month. Why don't we talk about this with her and see if you can convince her otherwise."
Kayla waved at Olivia to get out of the pool and to come over. Olivia got out walked over, grabbed a towel and started drying herself.
Kayla said, "Olivia, Ken and I were discussing what we talked about earlier, you know, the 'arrangement' of our intimate relationship."
Olivia said, "Okay, so what do you think, Ken?"
I looked at the both of them and slowly shook my head. I said, "You girls are moving too fast, there are a lot of huge consequences that will happen if the word gets out about this."
Both of them chimed in together, "No one will find out, we promise not to say anything to anyone."
I said, "How can I be sure that this does not leak out. Do you really understand what the ramifications would be if anyone found out? Plus, this huge chance we would be taking is just for sex!"
Kayla said, "We know that this could be extremely horrible for us all if somebody found out, and yes it's just for sex, but I have so much fun with sex, I always want more."
Olivia said, "I know you don't even know me, but you can really trust me. I truly understand the big mess this would create if someone found out, and I too enjoy sex, even if it's only been with a couple of people."
I said, "I don't know girls, I'm really uncomfortable with this."
Kayla said, "Let's go inside and talk about this further."
