As my wife pulled the bikini bottom up she was struggling to get the straps right, so I thought that I'd better save the day and I quickly got up and ...went to see how she was doing. Stacey pulled the curtain wide open and showed me the suit. I complimented her on how well it showed off her sexy little body, but she thought the fit was wrong.She pulled the curtain closed again and turned her back to me in order to try on the last one a white bikini. This time she didn't even get the curtain shut. “Me,” she said with a grin and turned to walk to her room.Once Donna and Todd were in her room, he started to close her door.“Leave it open,” she told him. “It will make it easier for us to hear anyone in the house.”“Right,” he answered and left the door fully open. Turning to face his step-sister, Todd asked, “How do we start?”Dropping down on her bed, Donna answered, “I think we have to get naked and do some examination of each other’s bodies. I doubt that you know any more about a female. I moved back in right away. I bent down even further and basked in the odor."My god Bev," I murmured, "you smell so-o good" I looked at her puffy lips from the front. The glistening of the inner line spread out in a fan. "You make me dizzy," is about the last thing I remember saying for awhile.I somehow got her backed up to the bed, and then she toppled down on her back. Her knees stayed high and waving far apart. In an instant I was on me knees, my mouth wide and glued to her cunt spreading it. While kissing her neck n licking her ear lobe i went down a lil n put her soft, tender, supple boob in my mouth n sucked on it softly to which she moaned ‘unnnnnnmmmmm saarooooo mood ochesindi saarooooo-am totally turned on and into the mood now sir’ and i said ‘manchide kadaa darling-its good for us darling’While sucking on both her nipples i opened the string of her pyjama n slipped my hand straight to her pussy n started rubbing it over her panties to which she immediately took off her.
