Within a few minutes, my little sister, Alison, had recovered from the colossal finger diddling I gave her deep inside her panties. After making sure she'd be able to stand on her own two feet after her thunderous orgasm, I relaxed my hug and leaned back to look at her. I had to chuckle to myself at the way she thrashed and then went limp in my arms as she came. I was impressed at the massiveness of what she experienced, and apparently, Alison was impressed, too, judging by the look of complete exhaustion on her face.
"I'm going to want those panties." I said to my little sister, pointing down to the thong she was wearing. "That's going to be one of our hard and fast rules from now on." I added. "I'll collect your panties periodically and you might end up going through three or four pairs a day, but, don't worry - I'll make sure you have enough clean ones."
Alison giggled and then blushed as she pushed her thumbs into the elastic band of her underwear as if she was going to skim them down her legs and give them to me, but, I stopped her.
"Hold on." I said quickly. "I'll want to take them off myself...... that's part of the fun for me, but, I want to save that until we have time for me to really enjoy them the way those panties deserve to be enjoyed. We have something more important to do right now."
I reached my hand out to Alison and waited until she took it in hers. Then, without further explanation, I led her out of my room, down the hall and directly into her own room. I pulled her in front of her computer desk and told her she needed to email her friend Brent and break their date. Alison started to pull out her chair to sit down, but, I told her I had something else in mind.
Pulling the chair completely away from her desk, I put my hands on her hips and positioned her right in front of her keyboard and then pulled her back towards me two steps. Then, reaching down and tapping the inside of her knees, I told her to spread her feet apart. Immediately, she did so, and once she was settled, I put my hand on her shoulders and applied a little downward pressure.
"Bend over at the waist." I instructed.
I pressed on her back until she was bent over with her butt stuck out in a very unlady like position. I continued to push her down until she could rest her forearms on the desk and easily reach the keyboard. Then, I told her she was going to send a short, but clear email to Brent telling him something had come up and she'd be completely indisposed all weekend. I also told her to tell him she'd catch up with him at school after the weekend to explain.
"That's all I want you to say." I told her. "Short and sweet, and that's it."
"There's no school on Monday." Alison informed me. "It's a planning day for the teachers."
"Good." I replied. "Then we can spend the day together while Mom and Dad are at work. Go ahead and send him the email and we'll worry about what to tell him later."
Alison didn't question my direction at all. In fact, I think she felt relieved to break her rendezvous with Brent after hearing what I was offering her. And for the time being, this was the first step in getting Brent out of the picture.
So, as Alison bent over to get her email started and begin working on the note, I busied myself by bending down behind her and staring in between her legs from the back. Now, I've always enjoyed looking at a female from behind, and even more so if she's standing right in front of me wearing panties. But, this was the first time a beautiful girl was bent over in front of me with her legs spread who would, for a lack of better terms, let me do anything I wanted to her. This would be an opportunity for me to enjoy the view of my little sister in her panties, and, to begin indoctrinating Alison into the finer points of my panty fetish.
Carefully, I reached up and put my hands on her butt cheeks, touching her briefly with just my fingertips and then resting each of my hands on the soft cheeks of her ass. I massaged her butt for a bit, and then slowly began to pull her cheeks apart. Almost immediately, I could see the back of her thong as it traveled up and down her crack, and as I spread her open some more, I could finally see the crinkled rim of her anus and the very bottom portion of her pussy lips.
The position she was in was perfect for rear-end viewing. He legs were spread just enough so I could see the full width of her mound between her legs, as well as her panty as it covered her pussy lips.
Her panties were indeed soaked. Even if I hadn't felt their wetness while I was masturbating her earlier, I could now actually see that they were sopping wet. These panties would be a treasure to have once I took them off her, and for a few seconds, I wondered how she would react when she saw me sniffing and sucking the juices out of the gusset of her thong. My hopes would be that she would get aroused seeing me enjoying her panties, but, whether she did or didn't would deter me from doing it. If she was going to be my submissive, she'd have to get used to the idea that her panties were going to play a big part in my pleasure, and if she was smart, she'd understand the importance of playing along.
It wasn't the right time to tell her, but, I made a mental note of the fact that this might be the last time she ever wore a thong -- at least in the foreseeable future. I much preferred full back bikini panties or boy shorts, and that would be one of our rules. But, for now, I was enjoying the view too much to worry about any of that. What an amazing sight it was -- and as I kneeled behind her while she was bent over and spread apart, all I wanted to do was impale my nose against that tiny triangle of fabric that snugly covered the entrance to my little sister's eighteen year old virgin pussy.
I swear, I would have loved to lick her as she stood bent over like that. I probably could have spent a good hour just licking up and down her beautiful crack, tonguing her and nibbling at her panties, but I knew I needed to take her training slowly -- one step at a time. But, soon, the time would come when I would thrust my face into her crotch from behind and take my pleasure.
I wasn't hearing any clicking of the keys on the keyboard, so I peered around from behind her beautiful butt to see what she was doing. I suppose I shouldn't have been surprised to see Alison leaning down on her computer desk with a dreamlike look on her face and her eyes closed. Quickly, I reached up and smacked her right butt cheek smartly with the open palm of my hand -- not very hard, but hopefully enough to give her a little tingle.
"Ooohhh!" She exclaimed, rising up and reaching back to sooth her stinging cheek.
"Alison!" I said sternly, standing up next to her. "What were you supposed to be doing?"
In the matter of an instant, she realized she was supposed to be sending the email to Brent, and not daydreaming or thinking about what I was doing to her bottom.
"I'm sorry." She said, continuing to rub her butt. "I know..... I was supposed to be sending the email."
I placed my hand on her shoulders and pressed her forward and down. In turn, she bent at the waist again and pulled the keyboard to where she needed it and began typing. Rather than bend down behind her again, I dropped my hand to the cheeks of her ass and I started to gently rub where I'd spanked her. Then, I let my hand wander to the crack of her ass and slowly pushed my fingers down into her crack.
Obviously distracted by where my fingers were going, my little sister's typing stopped. I immediately pulled my hand out of her crack and slapped her ass again, exactly where I'd spanked her before.
