I held mum by the wrist and walked her to her bed, kissing her deeply I ran my hand over bra and she shuddered kissing me back and snaking her tongue ...ver mine. I unhooked her bra and latched on to a nipple with my mouth, she moaned deeply her fingers running through my hair. I caressed the other nipple pinching and twisting it, she moaned humping my thigh with her panty clad pussy, she was in ecstasy now ad I could feel her wetness through the panty “eat my pussy baby, work that magic tongue. One slim hand undid the belt of his trousers while the otherpulled down the zipper. She reached inside the boxers underneath andpulled out his throbbing, 6 inch member. She smiled hungrily and placeda gentle kiss on its tip and followed it with a row of kisses all theway down to the base of it. Then she slowly ran her tongue up the shaft.At the end of the stroke, without taking her tongue off, she locked herlips around the thick head and then slowly slid it in. She stoppedhalfway to the base. "Please... my sister," she panted, feeling her resistance breaking down even before it had a chance to establish itself."Fuck her," he whispered, bending his head down and kissing the sides of her neck."Ohhhhh..."The room was swimming around her. Tilting her head back, Linda sucked in air. She found herself standing on tiptoes as he pulled her lithe body against him. Her trim ass was moving gently back and forth in a soft, fucking motion, a hint of something much more intense about to come.. I looked around to see him get on his knees behind me, working his erect penis to its fully engorged eight inches. He was clearly aroused by the sight of my creamy white buttocks framed by black sheer stockings and suspender straps.He took a bottle of lubricant from the box and applied a good amount to my exposed bottom and his penis. He then took a small brown glass bottle and put a tissue in a little polythene bag, pouring some of the liquid on the tissue. He told me the liquid was poppers.
