A stunning babe in her mid-40s, with long, luxurious chestnut locks flowing over her shoulders, leaned against a tree at dusk, eagerly waiting for her lover.Her skin was flawless, her face defined by high cheekbones, plump lips, and large, brown eyes that sparkled with desire.She wore a lacy red bra and a matching thong, and her nipples peeked through the lace.As the moon rose higher in the sky, she caught sight of the man approaching her, Michael Vegas, a ruggedly handsome hunk in his early 30s.He was dressed head-to-toe in black leather, looking every bit the bad boy she was lusting after.Keisha's sexy sister followed close behind, equally stunning in her own right.She was shorter than her sister, but just as curvaceous, with massive tits, luscious hips, and round, shapely ass.She too was dressed in revealing lingerie, a strapless black bra and black lace panties that accentuated every inch of her body.As they approached their lovers, the four couldn't help but feel a pang of excitement at the prospect of what was to come.Come on now, baby, Michael said as he gripped her waist, pulling her back against him so that she could see nothing but his hard length thrusting in and out of her sister's tight, wet pussy.The older sister moaned louder and louder with every stroke, her pleasure intensifying until she finally let out a guttural scream as she came all over her lover's cock.Michael pulled out and stroked off onto her slick, red-hot body, splattering hot cum all over her tits and face.Keisha's sister shook her head in disbelief, unable to comprehend how this could be happening to her.But as she felt Michael's lips brush against her neck and heard his low, sultry growl, she knew that there was nothing she could do to stop it.Michael thrust himself inside her again, his hands roaming all over her lithe form as he explored every inch of her body.What do you want? he snarled, his voice dripping with menace.Keisha felt her heart race as she realized that there was only one thing left to do if she wanted to avoid becoming Michael's next victim.She stepped forward, getting between the two lovers and planting herself squarely in front of her brother-in-law.Get away from my sister! she screamed, her voice echoing into the still night air.Michael lunged towards her, but she dodged effortlessly, her body moving with lightning reflexes as she turned and landed a powerful kick straight to his groin.He screamed in pain, writhing and grabbing at his crotch as the cum exploded from his cock, spraying all over his legs and feet.As her sister tried to catch her falling body, Keisha pushed her way past her, grabbing hold of Michael's arms and pulling him away from her.It's not your turn, asshole! she screamed, slamming him against a nearby tree trunk.The older brother looked up, stunned, as Keisha pulled out a small, sleek vibrator from her purse and pressed it against his forehead.Take this, she said, her voice cold and ruthless.And never mess with me again.With that, she turned and stormed off into the night, leaving the three of them alone to contemplate the events that had just transpired.It had been a wild and crazy night for Keisha, and she knew that she would never forget it - or the thrill that had come with being fucked in doggy style by her sister's boyfriend.
