'Nina, my darling, we are three people with two appendages, willing and ready. What could that possibly give you that we can't?'
'Now, now, Lukey dear, this isn't for me.'
She winked and pointed at Ash's ass, which Luke had just slipped a finger into, massaging and relaxing it. She then held up the harness that went with the dildo and Luke smiled; now he understood.
Nina strapped the silicone appendage about herself, then sat on the bed on the other side of Ash, watching Luke's tender, expert ministrations to his asshole. She helped by pulling Ash's cheeks apart, and Luke dipped his head over the crack, running his tongue from top to bottom. Ash groaned again. Nina pulled a pillow closer, pushing it under Ash's middle so his butt was raised. Luke then had a better angle, and his tongue dipped and licked and suckled the softening ring.
Nina readied the dildo, covering it in lube and warming it up with her hand. When Luke finally pulled back from his expert rimming of Ash's anus, Nina moved between the slick cheeks, running the tip of the dildo up and down Ash's crack. Then she lodged the head in his softened ring, pushing gently to open it up, letting it gradually accept the shaft. Luke's face was only inches from where Nina was inserting her toy, watching closely as Ash's anus widened around the blue silicone, as Nina slowly pushed the length inside him, pausing to squirt more lube. She completed the insertion, her mound pressing against his crack under the harness, and she held there for several seconds, enjoying the feeling of penetrating instead of being penetrated. Luke shifted his hips, taking his cock in his hand and stroking it gently, waiting for her to continue.
She put her hands on Ash's hips, pulling backwards and withdrawing the toy halfway, watching closely as it slowly withdrew, the gummy ring pushing outward to expel the silicone. She dribbled some more lube on it, then slowly pushed it back in, stretching him out, enjoying the sight of it disappearing into his body. Then she withdrew again, more rapidly this time, then plunged it back into him. He convulsed, arching his back, and she moved faster, pounding the strap-on into his rear end, slamming her thighs against his in a steady rhythm.
'Luke, give me your cock!'
'Oh, it's not Luke's cock that's riding your ass,' growled Nina, slamming into him harder, 'it's mine.'
To her surprise, Ash laughed throatily. 'I know.'
'What?'
'You think I don't know what Luke's cock feels like in my ass? Come on, Nina.'
She looked annoyed, giving an especially hard thrust.
'Why'd you ask for his cock then?'
'Ungh, 'cos I want to suck on it.'
Luke gave one last tug of his dick before crawling up the bed. Ash, in between Nina's furious pumping into his asshole, got on his hands and knees. This gave her better access to his hole, and she resumed her rhythmic pounding. Luke knelt in font of Ash, presenting his cock for him to suck, and groaned as his whole length was sucked into Ash's hot mouth. Luke put his hands on Ash's shoulders, humping his hips forward, looking at the beautiful body speared between his crotch and Nina's. She was still jamming every inch of the dildo into Ash's ass, and was reaching around to grip his cock in her hand as well. She timed her pumping into his hole with her pumping of his dick, thrusting, squeezing, giving no respite as she felt his cock twitch and stiffen. She stopped her movements on his shaft, just gripping and holding it still as she slowed her movements in his rectum. He grunted, trying to move against her, relieve the pressure, but she kept her steady, slower rhythm, holding his cock tight and in place, prolonging the anticipation.
He let Luke's dick slip out of his mouth. 'Jesus, Nina, fuck me!'
'I am.'
'Stop fucking teasing and let me cum!'
She slowed down even further, withdrawing the dildo almost all the way, with only the tip still stretching his anal ring.
He sat up in a bid to push the dildo back inside himself, but Nina was ready and pulled back as well, just keeping the tip inserted, still holding his cock tight and steady. Luke moved closer on his knees, then stretched his legs on either side of them and lay back, so that Ash's cock was only inches from his own cock and balls.
