"Will you be alright tonight?"
"I'll be fine. I going to watch some more TV to give you two some space. I'll see you both in the morning."
Erica replied calmly.
I followed Kim to the bedroom, to discover that she was already in bed, under the covers, and likely naked. She watched as I stripped off my clothes. This would be the first time that it would be just Kim and me together in bed. Kim, my step sister, and me having sex alone.
Sex with Kim and Erica had become a natural thing the past few months. I seldom thought about the incestuous nature of fucking my sister. But this night, it did come to mind. I had to remind myself that we were step-siblings, and not related by blood. This allowed me to ignore any thoughts that what we were doing was really incest, and therefore by society's standards the wrong thing to do.
I slipped under the covers and embraced my sister. We kissed gently and cuddled, feeling the love and warmth of the other.
"Last night was really hot sex, wasn't it?"
Kim asked me.
"Yea, it really was."
I agreed.
"But I really like this new plan to spend time in one-on-one situations, even if one of us is left out."
Kim and I kissed some more, our hands now caressing the other's body. I could sense the arousal rising for both of us. Just as I ran my fingers over her slit, I felt her hand around my cock. I knew that soon enough I would be pumping my cock between her hot wet fleshy folds.
"How about an appetizer before the main course?"
Kim asked, using our code phrase for oral sex. Without waiting for my answer, she rose up, swung her leg over my body, and lowered herself into a '69' position. Her mouth inhaled my cock at the same moment my tongue parted her puffy, wet labia.
"Hmmmm."
I moaned at sensations from the dual pleasure points of my cock and my tongue. I focused my attention on pleasuring my sister, licking her labia, tongue fucking her vagina, and then sucking on her clit. Obviously she enjoyed all of this as she was doing a great job sucking my cock to a very hard erection. We were both moaning as the heat rose between us, our bodies beginning to sweat. My tongue could feel her labia as they swelled larger, and her fluids flowed even more, coating my tongue, lips, and face. Giving oral was such a sensory pleasure for me.
And suddenly Kim stopped and rose up off my body. Knowing that she loved sex in the doggy position, I was preparing for getting up and into that position. But Kim wasn't having that tonight. She switched direction from a '69' to a forward cowgirl, took my shaft in her hand, pointed my head at her entrance, and lowered herself fully down upon me. Then she paused there, my cock throbbing inside her, her walls clenching around me.
"I usually make you do all the work. Tonight, dear Charlie, I want to take control."
Kim spoke with a steady voice. She smiled as she looked down upon me. She leaned forward a bit, placing her hands on my chest, her tits hanging in front of me.
"I want to see your face as I tell you one of my secrets."
She began to raise her hips up and lower them back down as she slowly fucked me while she spoke.
"I know that Erica told you, before our first sexual encounter, that we both had a crush on you, even when we were just young teens. What you don't know is that even while I was falling in love with Erica, I have always had a burning desire to feel your cock inside me. Yes, I considered myself a lesbian, but with a fetish for your cock. For years I made love only with Erica. But when we started using toys, particularly the strap-on, I always imagined it was your cock penetrating my pussy. And finally we made it happen."
As she told me this story she had a look of hunger in her eyes, as if she was about to devour me. Her hips continued to rise and fall, her inner walls squeezing my cock, which produced waves of pleasure in my body. I could see and hear her breathing becoming deeper and focused as she slowly moved towards an orgasm.
Her story took me by surprise, but I supposed it shouldn't have. Just as I had been blind to the fact that she was a lesbian, and that Erica was her lover, I was also totally unaware of her long desire for my cock. I was very happy that the girls had reached out to me and we now enjoyed a fabulous life of 3-way love and sex. I was, like they were, very pleasantly surprised by the powerful emotional love we felt from our 3-way relationship. And these one-on-one times would only expand our feelings.
I didn't know if my sexual interactions with Kim and Erica had converted them from lesbians to being bi-sexual. I didn't know if experiencing one male cock qualified as becoming bi-sexual. But then again, they were lesbians while having only one female lover. Not that these labels really mattered.
"I love you Charlie."
Kim said just before leaning forward and kissing me. As our tongues met, I could feel her body begin to tremble, her cunt clenching my cock as a 'silent' orgasm rolled through her body. In response, my cock pulsed inside her and began to pump my cum deep inside her.
"I love you too, Kim."
I moaned into her mouth, our lips still locked on one another. I wrapped my arms around her as she lay on top of me. We could feel our own orgasm, and the body trembles of the other's orgasm, in addition to the clenches of her vaginal walls tightly wrapped around my pulsating cock. It was a magical moment we shared.
We held our embrace and continued sharing gentle kisses for many minutes as our orgasms slowly subsided. Eventually Kim rolled off my body and she laid on her side. I wrapped an arm around her as I spooned her from behind. And in this loving embrace, we fell asleep.
Later that night I awoke and could see Kim looking at me. Without a word ever being spoken, we made love again and it was a powerful emotional experience, in addition to another fabulous orgasm we shared.
+++++
Tuesday morning I awoke after a great night's sleep. I felt totally refreshed. I thought back to the previous night's love making sessions with Kim and a smile crossed my lips. It was a delightful experience, one that I hoped we could repeat. And I hoped that my Friday one-on-one with Erica would be similar.
Before leaving for work I made a point to catch Erica and check how she was doing. She told me that it felt different sleeping alone in bed, but she fully supported what we were doing with our relationships. She would be just fine.
Tuesday night was another of our 3-some nights in bed. Similar to Sunday night, it was a very physical, emotional event, as if we hadn't been together in a long time. The love and sex was fabulous and exhausting. I fell asleep sometime after midnight.
Wednesday night was a one-on-one for the girls. Early in the evening they retired to the master bedroom while I stayed up and watched TV by myself, something I hadn't done in a couple of months. Before midnight I went to sleep in the guest bedroom. I was grateful we had replaced the furniture in that room, as it now had a very comfortable bed. I fell asleep thinking about what my two lovers were doing with each other and I slept very well that night.
The next morning I caught both girls before leaving for work. They both appeared radiant, as if completely rejuvenated. They both thanked me profusely for allowing them to have a night alone. It was special for them to have one-on-one time, to rekindle that special love they had developed for each other, and to fall asleep in each other's arms. I was very happy for them.
So far it appeared that our new sleeping arrangements were producing positive results for all of us, individually and collectively. We all appeared to be even more in love with both of our partners. And it showed in our group sex that night. The sex was even hotter and more passionate. Somehow I managed to have sex twice with each girl. And we all participated somehow in all the sexual interactions. I don't think I had ever been as satiated sexually, and physically exhausted as I was that night. Friday morning I overslept and was late for work.
I wondered whether we were attempting to compress the same amount of group sex into fewer nights. I was concerned that oversleeping might happen more often. This was not an intended result of our schedule change. And I felt somewhat sensitive to this issue.
+++++
Friday night was scheduled to be my night with Erica, one-on-one. I really looked forward to this night, so much so that I felt embarrassed about wanting to be with Erica possibly more than with Kim. I so wanted to be fair to both, and our rule was I had to do the same for each of them. As it approached bed time, it was also obvious that Kim was not pleased about being alone that night. That had me concerned.
Erica and I retired to the master bedroom before 10 PM. I felt very comfortable with Erica, as she did with me. When we first got in bed we hugged and kissed and talked for a long time about our journey together the past several months. It had obviously been, for both of us, a very new and different experience in our lives. All three of us loved the 3-way experiences, and now would also be enjoying our one-on-one time.
Erica indicated that she wanted me to make slow, gentle love to her in the missionary position. Nothing wild or exotic. Just straight, simple sex, where we could hug, and kiss, and fully experience the pleasure of sex between two loving people.
Our foreplay consisted of a considerable amount of hugging, kissing, and caressing of each other. I considered going down on Erica, as I love oral as a part of foreplay, but she gently pulled me back from that. We just touched and stoked each other. Eventually we were both ready and eager and I slipped my cock into her vagina. Making love to her that evening felt like a whole new experience. We didn't speak, and our kisses were simple and gentle, lips only. Slowly our pace increased, but never became frenzied or overly physical. It was always gentle, and extremely pleasurable. Our shared orgasm was powerful, but quiet. While our breathing was heavy, neither of us cried out aloud. The sensuality of the experience was incredible.
