I’d gotten away with it after all. A few minutes later Rachel came out of the bathroom and rejoined her sister looking like nothing had ever happene.... The next half hour went normally, making coffee drinks and milkshakes, doing dishes. When I checked in on Rachel and Claire, Rachel just said “Thanks again for the shirt Drew, it was really sweet.” and Claire seemed even quieter than normal curled up in the corner, but I noticed she was watching me closely with her big green eyes. They left. Her truly spectacular curves were squeezed into a dramatically snug, white dress that was tighter and much shorter than the one their mother was wearing. It exposed an awesome amount of breath taking cleavage, as well as her full, lush, very toned thighs. She, too, was wearing five inch heels that were showing off her thighs and jutting ass cheeks, to their fullest advantage. To complete the tantalizing sight, their aunts stunningly beautiful face, with its smoldering, sexy, crystal blue eyes,. My arms flew out to my sides as I tried to grip anything as I shuttered thru the first of many orgasms of the day. Suddenly the man in my pussy held his cock deep in me as he tensed. He filled my pussy with cum as he grunted loudly. That sent the other man in her mouth off as he pulled out and held the head of his dick my mouth as he came. My cheeks swelled out as white streams of sperm tricked out the corners of my lips. I swallowed a few times and he pulled out. The guy in my pussy released. Real cute"!There must have been 8 or 9 people there already and I mingled and shared pleasantries up until everyone had arrived which made for about 20 people at the party in addition to Martin, Elizabeth, Heidi and me. It was quite the experience and a real turn on to be standing there with everyone dressed in dinner jackets or cocktail dresses, except for Heidi who was standing there stark naked except for stockings and gloves which Martin and his friends referred to as her 'formal Nude.
