"Hey, sis, the parents are out. Do you want to do what we did last time? You know, take our clothes off? C'mon, they'll be gone for hours and I know you like showing off. Uh-huh, you can keep your bra on but take off your blouse. Do you want me to take of my shirt, as well? I can see your hard nipples poking through your bra! Don't be shy, really, they look great. Oh go on, please take off your bra... there isn't that more comfortable? What? Yes, my cock is getting a little hard - do you want to see it? OK, but only if you pull down your panties - you wouldn't do that last time. Go on, oh yes, that looks so great. Ok, I am going to take of my underpants. Hmmm, my dick is sorta getting in the way... there done it. Will you open your legs for me? Please? I so want to see your sweet little pussy... look how hard my cock is getting! What's that? Have I ever put a finger inside a girl? No, not really. What? You want me to... well ok... hmmm... you are a little bit tight... there you go... does that feel good... oh, god, my cock is really feeling stiff. Why are you breathing so hard... gee you are really getting carried... away... do you want me to stop fingering you? Ok, ok, I won't stop. Oh god you feel so wet and I am worried that I might shoot some spunk if I do finger you any longer... oh, no, I can't stop myself... oh... oh... oh... oh.. ohhhhhh. That was great but I think we should get dressed again quickly in case the parents return. OK, yes we can do it again some time.. thanks sis!"
