I was feeling a lot of pressure about Tammy. Mom and Billy both say to bring her in on our secret. But I am still not so sure about it. I am feeling like I can't trust her and that everyone will find out about our relationship.
As the week went by I kept getting text messages from her with little comments like "How is your boyfriend doing?" or "Do you think I am blind I seen the way you were looking at Billy." I just kept ignoring them and would delete them without a response. I finally broke down and went to Billy.
"Can we talk about this whole Tammy thing?" I asked him as I sat next to him on the couch.
"Sure, what's going on?" Billy replied as he swung his arm around me. I leaned my head on his shoulder and let out a deep sigh.
"I have been getting texts from Tammy all week but I have been ignoring them. But I know that I can't keep doing that." I told him.
Billy squeezed my shoulders before answering. "I've gotten some too and I also have been disregarding them."
I looked at Billy before I brought up my concerns. "I understand what you and mom are saying about bringing her into our circle. But I am just concerned that she will tell everyone she knows." I paused for a minute then looked at Billy in the eye to tell him. "Billy, I don't want to lose what we have I love you and want this to work for us. I feel that if we bring Tammy into this it won't be just ours anymore and I will lose you."
Billy wrapped both of his arms around me to hold me tight, "Sis, we are not going to rush into anything. Let's think about what we could do." He informed me and I sighed.
We didn't talk about it again for a couple of days but I could not stop thinking about it. I kept thinking why can't we bring her in but she never finds out about Billy and I. I approached Billy in the kitchen about this.
"Billy what would you think about inviting Tammy here to live with us but make it so she does not find out about us?" I questioned Billy and he drew his eyebrows together trying to figure out what I was saying.
"Listen we have the small office that is basically a closet but we could clean it out and put a twin bed in there for you and she can have the second bedroom. Your clothes could go into my room because I have the big closet, so you could get ready in there." I suggested to him. Billy kept looking at me with an odd look on his face.
Billy looked at me and then asked, "When are we going to make love?"
I smiled and replied, "That is the good part, she works and goes to school so when she is not here, and in the shower or the bathroom when you are supposed to be getting ready." Billy just looked at me then he got a huge smile on his face.
He wrapped his arms around me and responded, "You know sis it just might work." I smiled and kissed him.
Billy pulled me in closer to him and started kissing me deeply. Which I was returning the kiss just as passionately. Billy moved to my neck and was kissing me in the curve to my shoulder. He pulled my shirt to the side to be able to actually kiss my shoulder. I moved my head so that he could get better access. His hands went up under my shirt along my ribs to cup my breast and squeeze them.
Billy pulled his hands out from under my shirt to pull it off over my head and he then unfastened my bra and pulled it off so he is skin on skin with my tits. I sighed when he started pinching my nipples and squeezing my tits. He leaned in to suck on my nipples I held his head against me. I didn't want him to stop the sensations I was feeling.
Billy then moved his hands to my pants, he slides his hands down the back of my pants to squeeze my ass cheeks and pull me into him. I could feel his erection through both of our jeans when he ground against me. I put my arms around his shoulders to kiss him passionately while he was rubbing my ass. He reached around the front on me to unfasten my jeans and pull them done along with my panties. I stepped out of the pants standing in front of him completely naked.
Billy stepped back to just look at me, I started blushing with embarrassment and put my head down. "What's wrong? Why are you getting embarrassed?" Billy asked me and I just shrugged my shoulders. Billy lifted my chin and very seriously told me. "Missy don't ever feel embarrassed with me! You are beautiful and I could look at you naked for hours!" Then he leaned in to kiss me which gave me goosebumps.
I started pulling his shirt off him, laughing I informed him that one of us had too many clothes on. So, while I was pulling his shirt off he kicked off his shoes and unfastened his jeans and pulled them down and stepped out of them. Now both of us were completely naked.
I just stood there looking at him watching his cock getting harder. He was flexing his cock to bounce up and down. I was giggling at him, he laughed also and asked me, "So you like that do you?" I then wrapped my hands around his cock and squeezed it lightly.
I got down on my knees in front of Billy still squeezing his cock, I looked up at him with a smile and told him. "Your cock is mine and I do not wish to share it!" Then I wrapped my lips around the head to start sucking on his shaft.
Billy put his hands on the back of my head to give me more of his cock. I was so hungry for him, I stopped and let him face fuck me. He kept hitting the back of my throat making me gag when I was ready for a break I grabbed his hips to slow him down. I pulled off his cock but kept stroking it with my hand.
Billy looked down at me and grabbed my hand to help me to my feet and led me to the couch. He pushed me over the arm and entered me from behind. "Oh, god yes fuck me hard. Give me all of it, I want to feel you deep in my pussy!" I yelled at him. He started thrusting harder slapping my ass.
Billy started to get much more aggressive than normal. He slapped my ass again and then told me, "You are mine and no one will ever change that! Do you understand me?" We both started to cum together as I screamed "YES!"
Once we both came Billy pulled out of me and helped me stand. I had wobbly legs, I turned to him and we held each other as our breathing slowed down.
Once we were calmed down we looked at each other, I leaned in to give Billy a light kiss on the lips. "Thank you for that and we will make this work for everyone," I told him before I pulled away to go to the bathroom.
After we got cleaned up I text Tammy and asked her to come over to talk. She went a message back that she would be over in about an hour. I told Billy this and he laughed. "At least the room will be aired out by then." He made mention and I started laughing also agreeing with him.
I was nervous when the doorbell went off, I got up to answer the door. Tammy was standing there looking smug. I invited her inside, she walked past me with her nose in the air. She sat on the opposite end of the couch from Billy as she sat down they said hello to one another.
I sat in the chair across from them, Tammy sat there with her arms crossed. I looked at her and shook my head at her. Tammy got frustrated and asked me, "So why have you asked me to come over here?"
"Tammy, I want to know what you think you are doing? You have been texting us all week with accusations about something you think you saw last week?" I responded to her question. Billy sat there quietly knowing that I will take care of this.
Tammy smiled smugly at me and replied, "I know that I saw you and Billy flirting with each other. You both were acting too friendly for a brother and sister more like lovers."
I laughed at her and responded, "Tammy I was drunk so of course I was flirting with everyone there."
"No, you were not! I was watching you and then I see you in the parking lot hanging all over Billy!" Tammy's response was starting to get very agitated.
