Kristina turned over and smiled, no hint of mischief in her dark brown eyes as Cherie began rubbing Sunblock on her front. She started at Kristina’s...feet and worked up her thighs, wanting to be bold and daring, but not daring to risk it with Terry and the kids nearby. She slid Kristina’s barely-there bikini down a bit to get a bit on her hips, but not off. Her hands traveled up the smooth, flat plane of the blonde’s stomach and was nearing her tits, those yummy, lickable, round, perfect, bouncy. ”David could not, of course, make any comment. Nor wouldhe even were she to remove the gag. But calling himslave, he thought, was going too far. Although, she wasclearly treating him like one and perhaps it was lessderogatory than ‘Wanker’.He glanced to his left as Karin dismounted, to see herstepping into a pair of ‘dildo pants’. The sight of herin black boots, stockings, basque and now sporting asix inch powerful erection was both worrying anderotic. Still gagged. He began to lick her ass again. In no time her ass began to gape again. As he licked he applied lube to his cock. He quickly stood and placed the head against her gaping ass. He looked her deep into her eyes and she nodded her head yes. ****He rammed it in as deep as he could go and held it until she relaxed. She squealed and her ass squeezed tight around his cock. He waited for a few minutes then asked are you ready again. She nodded yes. He began to slide his cock in and out and applying lube. His face appeared to be covered in female juices, and he looked utterly exhausted."Are you okay, mate?" Yes, that was amazing, but I'm absolutely knackered. They insisted on a threesome, with one on my face and one on my cock, and they kept swapping places! I'm going to have to have a kip before I can be of any use to these two." It's okay, Twin, it'll just be Sian. When you've recovered, I want you to give our cousin the most amazing orgasm of her life. Make love to her like you do to me,.
