The next morning I stayed in my room to catch up on homework that I needed to finish before heading back to State. I heard the girls get up just before 11 AM. I knew that they had stayed up late talking. I was not sure how they, especially Annie, would be feeling about me. In fact, I was a little nervous about the whole thing, so I thought it best to stay out of their way. It sounded like they were having fun cooking up a big breakfast, which I took was a good sign.
About 1 PM or so, Kathy knocked and asked, "Are you decent?"
I said, "Sure, Sis, come on in."
She entered alone and said, "Annies' Mom needed her at home, so she picked her up a few minutes ago. I'll see her later at our cheer practice this afternoon. That's why I have my uniform on."
"Oh, I'm sorry I missed her. I just had to get caught up on this school work."
"Are you almost done, Jimmy? I mean, if you're busy, I can leave you alone?"
"No, Kathy, sit down. I'm all caught up on schoolwork. I thought it was best for me to stay out of your hair this morning, I felt like it might get a little awkward if I were to be around, so I just stayed in my room and found some extra things to work on."
As Kathy walked over to sit next to me, she said, "I guess I do understand how you feel, Jimmy, but I think Annie had a good time, and I know she enjoyed meeting you."
"I suppose she did a little more than meet me, eh Kathy?"
"Well, (with a little chuckle and smile) I guess that is true. She did a little more than meet you. That's why I wanted to make sure and see you as soon as Annie left. I was kind of worried about you. I thought you might have some second thoughts about all that happened. But I know that Annie really likes you. We were up late talking about you. More than anything else, she was excited to tell me how lucky I am to have such a cool brother."
"Wow, that's nice to hear sis, I was a little nervous about what you might say, so that's a huge relief."
Kathy seemed a little serious, and I asked her if everything was alright. I even thought I noticed a tear or two as she wiped her eyes and sniffled a little bit.
"Jimmy, we had such a good time yesterday, but then I remembered what happened on Friday night. Do you still need to spank me before you leave for school?"
"Oh Kathy, I'm sorry that is upsetting you."
I gave her a nice hug and told her that I agreed on how much fun it was yesterday. I even said that she deserves the credit for making it a great day. "I was amazed and am so thankful that you actually asked Annie or almost told her to show me her tits. Once you said that, I knew Annie would not be able to refuse your request. I did not believe that you could read my mind as I had been thinking about her tits ever since she came over. It was fascinating to see how rock-hard her nipples were once she removed her bra. They were better than I had imagined. So thank you for that."
Kathy smiled just a little through her tears and said, "It was really fun. I'm glad you and Annie got to know each other."
I put my arm around her shoulder and whispered, "Kathy, you are such a wonderful step-sister. I really do know how lucky I am."
She sniffled a little looked into my eyes, and said, "I know that I am the lucky one, Jimmy."
Kathy then began to lean forward toward my lap slowly. I only had to give her a little guidance to get her into a perfect position. I told her how proud I was of her for understanding that it is still important for us to finish her spanking from Friday.
"Yes, I do know that, Jimmy. You do need to spank me now."
Kathy's short uniform skirt did not cover very much once she was across my lap. I just needed to lift it a few inches to reveal her red uniform panties. I patted her bottom on top of this garment and told her that I was surprised she had them on.
"I know," Kathy replied, "But when you pull them down, you will see that I am not wearing any of my own panties underneath."
I inserted my index fingers into the red garment and took them down to her knees. She lifted just enough for me to remove them. Once again, I had the fortune of looking at and gently stroking a beautifully soft, very white teenage bottom. I began Kathy's spanking with several quick and firm strikes to each cheek. These were quite a bit harder than those I had given her on Friday, and it surprised Kathy a good bit as she let out a loud, "Wow, wow, wow, Oh my goodness. Oh wow, oh wow." At the same time, kicking her legs and wiggling uncontrollably on my lap. I knew I wanted this spanking to be more aggressive, so I held Kathy securely as I spanked and slapped her perfect little bottom. After a minute, I took a break to see if I may have overdone it.
