I'm supposed to be the responsible one! I'm supposed to be the one setting the good example for my younger sister and helping her out in times of need... At 28 I really should have my shit together by now, but it's no real surprise that she's the more successful of us. Amber is only 25 but she's very career focused, so much so that she hasn't given much time to finding a long-term relationship or starting a family.It could be worse of course. All things considered I'm still very lucky to have. I placed Claire on her back on the sofa and then lifted her left leg up onto the back of the sofa, then placed her right leg on the floor thereby opening up her panty crotch to my curious camera. Claire was giving me mixed signals with her facial expressions. Sometimes, a silly little smile, sometimes bedroom eyes as she voluntarily opened her legs a bit further. I then moved her to a kneeling position on the carpet with her chest on the sofa cushions. She looked back at me very much aware. Taking hold of a firm nipple I tweak it before I slowly slide my hand down to my dick and straighten my snake again. With both hands now resting on her hips, just at the top of the string to her thong. I think, ‘do I try my luck’? Seconds later a finger and thumb from each hand pulls the tiny bows releasing her thong. Joanne, feeling the release slips her hips forward and the material falls way exposing her sex. Kneeling before her I look into her eyes, “May I?” Smiling she opens her legs wider. John was in the corner against the wall next to Barbara then me on her right and then Emma on the end. We had some more beer and wine and another joint during the movie.We had turned the lights out to watch the movie and when the movie finished, we turned off the TV and it was very dark even though the curtains were open for ventilation. There was no moon that night and only the hint of light from a distant streetlight. I could just make out the silhouette of Barbara removing her singlet top.
