Two days after my meeting with Erica, I received a text message from my step-sister, Kim:
"The usual time Sunday?
Shall we bring anything?"
My immediate thought was that this was a sign that Erica had shared with Kim the discussion we had Wednesday night and that they both were onboard for a sexual 3-way encounter that would forever change the nature of our relationships. I wasn't sure whether they wanted to start earlier than our usual 5 PM to have more time for our new activities. Maybe I should suggest they bring their toothbrushes and spend the night. But I considered that would be getting ahead of things. Besides, this 3-some might be just a one-time deal to fulfill a fantasy that each of them had.
Our relationship was changing rapidly and I needed to continue walking a tight-rope of playing the role of older, responsible big-brother and substitute parent, and the new role of male lover for a couple of bi-sexual females. I had to keep reminding myself that Kim was not a biological sister, but only a step-sister without any blood relationship. If neither of us considered our interactions as incest, we should be fine. And no one else besides Erica would know. However, I had a while back discussed the evolving situation with my friend Joe, but he told me to go for it.
"What's the harm?"
he had said to me.
Our usual Sunday gatherings at my home were for dinner and conversation. We frequently began with drinks, either wine or margaritas. The whole thing from start to finish would last three to four hours, and then the girls would return to their campus dorm.
But this week would be different, very different. They had lured me into fulfilling their sexual fantasy of a FFM 3-way. As I had just recently learned, neither of the college juniors had ever had intercourse with a male. Now they both wanted to experience sex with a real male cock. They choose me to be part of their fantasy as I would be an emotionally safe choice. They felt that I wouldn't develop other emotional feelings for either woman, and neither of them would develop emotional feelings for me which might lead to complications in their own stable lesbian relationship.
I decided that my text reply would include another event, should they choose to accept.
"Come between 2 & 3.
Bring swim suits.
Frozen strawberry margaritas, dinner
and other activities to follow."
She quickly responded:
K ;-)"
This new relationship was initiated by Kim and Erica by their posting photos and videos on Kim's cloud account, knowing that I had her username and password to access that account, and then leaving hints that I
shouldn't
go there to view her naughty photos. This, of course, made me go look. Eventually I was regularly checking the 'Private / Don't Look' subfolder for newly posted material. And they were leaving photos and videos intentionally for me, even talking to me in some of the videos.
Now that they had me hooked by their scheme and we were scheduling our 3-way encounter, I wondered if it was necessary for me to check her cloud account again. I figured it wouldn't hurt, and I did enjoy viewing their naughty photos and videos.
On Friday night I logged in to my step-sister's cloud account. I was pleasantly surprised to find some new photos in her 'Private / Don't Look' folder. The photos were of Kim and Erica, scantily dressed in their new lacy underwear and holding up signs that read 'See you Sunday @2' and 'Can't wait'. I smiled while my cock throbbed. These girls knew how to get to me.

Sunday mornings were my usual time for doing laundry and putting out fresh linens. I made sure the hall and master bathrooms had fresh bath towels, hand towels, soap, shampoo, and hair conditioner. I put clean sheets on my bed while thinking about what may happen there later in the day. My cock stayed at about a 6 on the 1-10 hardness scale all morning long.
I put a brisket on low heat on the grill to be ready for dinner later that day. And I made a double batch of frozen strawberry margaritas and put those in the freezer. I knew these had plenty of tequila and would not freeze hard, but would stay smooth and servable all the day. The margaritas would also calm our nerves about our new encounter. Early in the afternoon I put on my swim trunks and a t-shirt.
Just after 2 PM my doorbell rang. Unusual I thought, they always just let themselves in. I walked towards the front door just as it opened and in flowed Erica and Kim. They were both dressed in Daisy Dukes cut-off jeans and crop-top t-shirts with exposed midriffs. Wow! They were smoking hot!
Erica walked right up to me, threw her arms around me in a big hug pressing her voluptuous breasts against me, and gave me a lip-lock kiss and her tongue thrust into my mouth. After a few moments we broke our kiss and I took a deep breath of air. Before I could say 'Wow', Kim gave me a similar tit-pressing hug and lip locking kiss with full tongue action. This was some serious heat. At the moment I was stunned by their actions and gave no thought to the fact that this was my step-sister kissing me this way.
"So glad to see you."
Was all I could fumble out of my mouth. Kim and Erica were very energetic and happy, almost giddy.
'I can see this is going to be a lot of fun.'
I thought to myself.
"Did you bring your swimsuits for the pool?"
I asked as we walked towards the back of the house.
"Right here!"
replied Kim while holding up a small bag. To me the bag appeared too small to contain two swim suits, but that just meant the suits were skimpy and wouldn't cover much. My cock twitched. I could see that I was going to have problems containing that in my trunks.
"Why don't both of you change while I pour us some drinks? You can change in either the guest room, or my room. And you won't need to take towels outside. I already have plenty of towels out by the pool."
Without replying the two girls bounced down the hallway, giggling along the way. I noticed they went to the end of the hall, where the door led to my bedroom. My cock twitched again while I thought of the two women changing clothes, and momentarily getting naked in my bedroom.
I took the first container of frozen strawberry margaritas out of the freezer and poured three drinks into large acrylic margarita glasses. These party glasses were safe to have out by the pool, they looked great, and they held a large amount of the slushy concoction. I placed these on a tray and took them out to the pool-side table. The table umbrella would shade the drinks so they wouldn't melt too quickly. I removed my own shirt and threw it over the back of a chair. Then I placed pool towels on three of the chaise loungers.
By this time the girls had changed and they walked outside to join me by the pool. They were both stunning in their skimpy bikinis. Kim, a redhead, wore a fire red suit while Erica, a blonde, wore a bright yellow suit. They were both practically busting out of the tops. They looked fabulous. I had seen both naked in photos and videos, but this was the first I had seen them wearing so little, live in person. I could feel my arousal rising, as was my cock in my trunks.
