I slid my hand down and up under her skirt and felt her inner thigh and then rubbed her pussy through her knickers.She looked me in the eyes with such...an innocent expression on her face, her lips were parted as she sighed and was clearly enjoying my probing fingers between her legs. I moved my mouth to hers and started snogging her while my fingers explored her tiny little tight pussy inside her knickers.She started moaning into my mouth, I had only managed to get one finger inside her, so I. ‘Vince, I am really close. I am going to cum again.’ ‘Cum for me, Gabby I want you to cum for me,’ as said as he sped up and pushed harder and faster He fucked her as hard and fast as he could as she came and came and came. Her body shook uncontrollably as her pussy walls clamped around his cock and she dug her nails into his shoulders as he continued to fuck her hard. As she came down from her incredible high she could feel him began to tense up. ‘Oh here it is Gabby, I’m going to cum, oh yeah. Then something quite remarkable happened. Something that had a lasting impression on me. Elizabeth casually crossed her legs revealing an impressive expanse of thigh, stockings and a neat pair of white knickers. It only lasted for a second, but it was delicious. Elizabeth carried on talking, apparently oblivious to the little treat she had given me. I wanted to see her knickers again, but the chance did not come up. I kept wondering if it was an accident or whether Elizabeth had intended to. I’m the 28 year old brother of a beautiful 19 year old sandy blonde haired sister. My name is Mike and Michelle is my sexy little teenage sister. I'm about 5' 10", well built, light brown hair with blue-green eyes. Not to sound conceded or anything, but I've been called good looking by many women and some have said I look like Mel Gibson. Frankly, I don't see the resemblance but the compliment is appreciated. My sister Michelle came to stay with me for awhile after she broke up with her.
