She stared, fascinated, as Mindy’s motions became more and more urgent. She could actually see her sister getting more and more turned on! It was so...wild! Mindy gripped Ben’s shoulders and her hips kept moving faster and faster. Things were happening inside her. Wonderful things! ‘Ohhhh!!! I’m gonnna come!!! I’m gonna come!!!’ she yowled, ‘Oh, yesss!!! Oh, yessss!!! I’m comminnngg!!! Mr. Sanders, Sarah, I’m…I’m commmmmminnnnnggggggg!!!!! I’m…Ahhhhhh!!!…comminnnnggggg!!!!!’ Ben enjoyed the view. Then holding Liz's panties to the side, Dee Dee spread Liz's lips wide as I drank her sweet nectar, lapping every drop as it formed in her. Dee Dee slapped Liz's ass hard a couple of times, then spread her ass cheeks and began to tongue fuck her tight rose bud heartily. Liz was bucking wildly as she sucked at my cock. Her hand pumped at me as she begged me to cum in her mouth. My fingers pounded Dee Dee's pussy from behind as she brought Liz towards another body shaking orgasm. Dee Dee's loud. Kyle watched it all and felt jealous of Melissa for the first time in his life. He missed having sex so much and here was his sister having a very vocal orgasm right before him. He wondered if he would enjoy sex that much when he got to be her age. He felt his flat chest and wondered if his breasts would be as big as hers and would he have a boyfriend like Billy to satisfy him.Before Kyle had a chance to run back out to the hallway, Melissa opened her eyes and spotted her brother at the door.. Watching her hard nipples through her tank top was to much to resist and I massaged her breasts lightly as she stood over me. I whispered to her how sexy she was and suggested having a beer.She really seemed to listen to my advice and seemed to gain some confidence. I tossed on my tank top and boxers and walked into the living room.We sat on the couch and she turned on her gas fireplace to take the chill out the air. The flames lite the room with a warm flickering glow. As she began to massage.
