Right then she grabbed my head and moaned "Stop!" I stopped both my hand and tongue, but left my finger in her pussy. She jerked a few more times, the... started to relax."Was that you cumming?" I asked."Yep . . . that was really good . . . with a little training, you could become a master pussy licker!" She dropped her legs to the floor, and relaxed with a big sigh. I sat back and looked at my sister, bare naked, legs spread, moist pussy staring at me. "Can I look closer?" I asked her. "Sure, if. Ahem, sir? Go ahead and take a deep sniff of your daughter’s panties for the next part of the demonstration.Okay, so you can see him sniffing his daughter’s panties now. He is about to be hit with an overwhelming dose of her pussy pheromones and we’ll now observe the effect it has on him.Ah, here we go, he instinctively goes to check that they are her panties by looking up her skirt.So now he’s seen she isn’t wearing any panties and therefore can deduce that the panties he was sniffing do. We had dinner together and came there, after dinner I asked her to wear dress which is more accessible for me, she said oyy. And smiled and went to change her dress, she came back with red jacket (as it was winter season so lot of dew, and it was very cold) and black legging. We sat there and were chatting for some time. Now we again started to smooch. She said she wanted to sit on my lap, she sat and we were kissing for some time. What a lovely moment it was. I just bent her on my lap, now I. Yes, yes, your hand and mine together can do it. Ah, yes, roll this way, baby. Spread those beautiful legs. I love the way you kiss, your tongue polishing my teeth. That's it, baby, it goes right in to your cunt.Plunge, plunge, plunge, fuck, fuck, fuck, oh shit, it's gone. Shit, shit, shit."I'm sorry, baby, I just can't help it. This fucking cock has become my enemy." That's all right, Stephen. Please let me have my vibrator."Damn. This morning, I had refused to get it for her and we both went.
