I really had no idea. Alyssa popped her head in my room, said, "Wait," then disappeared downstairs. A few minutes later she was back in my room. "Mom's busy with laundry," she said as she stripped down naked, then lay upon my bed. "Come over here and eat my pussy," she said to me. Her legs were wide apart. She was freshly shaved except for her landing strip. She pulled her clitoral hood back so I could see just how erect her clit was.
My eyes were closed as my mind went on a journey through the cosmos. That is how I always viewed going down on her. It was such a fantastic thing to experience. I slowly ran my tongue around her clit in a clockwise fashion. Three minutes in and her breathing began to become labored. She was softly moaning as I continued to service her. She finally held my head in place as she screamed, "Oh, Yes, Greg. Eat that pussy good," and then she rewarded me with a mouthful of her warm, sweet, sticky juices. I took my time lapping them up. She never tired of me doing so.
I removed my shorts and lay back. Alyssa crawled between my legs and took my balls into her mouth. My scrotum was already tight, so her tongue felt extra nice as she bathed it with her saliva. She kissed her way up my cock, then took the head in her mouth. She was exceptionally aggressive. I knew she wanted my semen. I concentrated on giving her all she could stand. Five minutes in and I moaned into my pillow as I shot stream after stream of cum into her mouth. She swallowed every bit of it, giving a satisfied, "Ahhhh," when she was done.
Alyssa hopped up and grabbed her clothes and dressed while I did the same. "So," I said as I pulled my shorts on. "Any ideas for me yet?"
"I was thinking of a guy and his granny" Alyssa said. "He sees her naked one day and decides he wants to fuck her so he makes these outrageous bets with her, like if she wins then he'll kiss her ass, or he'll suck her toes for thirty minutes, and then he'll give her a full body massage, and then on the last one he says, 'Name it,' and when she wins she tells him he has to go down on her. Something like that?"
"Hmmmm," I said as I took this in. "It sounds pretty good. I think I could work with that."
"You can thank me tonight when the folks go to sleep," she said with a smile and a wink. For the record, I did. About three months into our relationship, Alyssa announced that she had been stretching her anal tissue and she was ready for anal sex. This had opened a whole new dynamic to our relationship, one we both happily accepted. This is what I gave her on this night after Mom and Dad went to sleep.
I ate her ass for the better part of thirty minutes before lubing my cock with her cum, then I eased myself into her. It was ecstasy, pure and simple, and I was so worked up that I gave her a double feature, spending all of about forty-five minutes in her ass, which she didn't mind at all. Afterwards, I ate her pussy good for her until she had one final orgasm, then we drifted off to sleep in each other's arms. She posed the question of someone walking in on us, and while I was not a staunch supporter of that scenario, she and I did very little in way of ensuring it never happened. It hadn't, though. In fact, even after six months our parents still didn't suspect a thing.
The following day I was writing the story and it was coming along just fine. As big a block as I had mere days ago, I was now typing at the speed of light as I fleshed out my sister's suggestion. I was really hammering the keys hard when I heard, "Greeeeeg?" I turned to see Alyssa enter my room. She lifted her skirt to show she had on no underwear, then lay on my bed and opened her legs to me. "Just five minutes, Greg. Please? I just need to have an orgasm right now."
I laughed as I slid from my chair and onto the floor. "Like you even have to ask." I crawled to her and began eating her sweet, soft pussy. I heard a creak. Mom was coming up the stairs.
I attempted to pull back, but Alyssa held my head firmly in place as she whispered, "I'm almost there." No more creaks, but Mom's footsteps could be heard. I panicked, but Alyssa continued to hold me. "Just a little bit longer," she whispered, I savaged her clit with my tongue. She locked her ankles around my neck and began to thrust just as Mom's footsteps got fainter. She was no doubt heading to her room.
A few moment's silence, then Mom shouted, "Alyssa?"
"I-I'm cumming!!" Alyssa shouted out her reply. She ground my face into her pussy as she spasmed, allowed me about fifteen seconds of licking her sweet insides, then she was trotting down the hall. "Yes, Ma'am."
I washed up, popped a couple of Tic-Tacs in my mouth, then settled in at the computer once again. You know, just in case Mom should pop in afterwards? Didn't want her smelling our sex. I got a couple of paragraphs in when Mom knocked and entered. "Greg, your father and I need to have a word with you and your sister when he gets home from work."
There was no lilt in her voice with which to foretell good news. Then again, there was no hint that we were in trouble, either. Even still, my immediate thought was that she knew about Alyssa and me, which prompted me to ask, "About what?"
"When your father gets home," she reiterated, then left.
Alyssa entered my room about fifteen seconds later, once Mom had returned downstairs. My chair was still facing my open door. "Any idea what that's about?"
"I don't know," she answered. "Guess we'll just have to wait."
"Do you think she knows?" I asked.
"I don't know," Alyssa answered.
"That's what you wanted, isn't it? To get caught?"
Alyssa said nothing. She stood there for all of fifteen seconds, then she returned to her room.
Mom timed her activities to where she had returned to her room for a shower about fifteen minutes before Dad got home. After a hello to me and Alyssa, he entered the bedroom as well and closed the door. Alyssa came to my room and sat on my bed. She was wearing shorts and a Hello Kitty T-shirt. I guess the thought of actually being found out was not as exciting as she had originally imagined. We sat there, me in my computer chair and she on my bed, until Mom and Dad entered just long enough to say, "Come on, you two. Let's go downstairs."
Mom was dressed in a black evening gown and Dad was freshly shaved and wearing one of his better suits. Their intermingling colognes complemented the other. We were led to the living room. Mom and Dad took the love seat while Alyssa and I took separate ends of the sofa. They both looked at us curiously, then at each other. "Are you sure?" Dad asked Mom.
"It needs to be addressed," Mom responded. "If not now, then when?"
Dad eyed us again, then said, "You two are adults now. We have coddled you in the past simply because you are our children, but you are our adult children, which means that your mother and I must extend to you more trust and respect. There are two things we are going to tell you this evening, and it is with the hope that you have the maturity about yourselves to fully understand and accept what we have to say that we do so."
"Oh, God!" Alyssa broke in. "You're getting a divorce."
"Alyssa ... No," Mom said. "I love your father very much. We're not getting a divorce."
"Is one of you dying?" I quickly asked.
Dad laughed. "No, son. Your mother and I are both healthy and strong and in love with each other even more today than we were when we first met."
"Well, if you're not divorcing and you're not dying then I can accept anything else you have to say," Alyssa told them.
"Let's hope so," Dad said, then he took a deep breath, then he said, "Your mother and I have agreed to an open relationship."
"What?" Alyssa and I asked in unison.
"I thought you said you loved him," Alyssa said to Mom.
"She does, and I love her," Dad replied. "It's just ... Okay, here's the deal: After Greg turned one, your mother and I began swinging. Sometimes we would swap partners, and sometimes we would have threesomes. Regardless, it provided a spark that our relationship needed. For over eighteen years we have been happy with this lifestyle, but lately we both have been wanting something else, something more intimate. We discussed it, and this is the road it has led us down. It's not about love or lust, kids, but more about just sharing ourselves with other like-minded people."
"We want you to know this because there may be times when one of us doesn't come home of a night," Mom added. "Now when we call to inform you of this, you'll know why."
Alyssa and I both just stared. I finally asked, "What's the second thing?"
Mom and Dad smiled simultaneously. Mom answered with, "I don't know if this will be harder or easier to accept, but it's all part of the same deal. You know, us and our sexuality? Anyway ... Your father and I are both ... bi-sexual."
I stood and hugged Mom, then Dad. "If this is what you need in your lives right now, far be it for me to say you are wrong. So long as you guys are happy, I'm happy."
