Carla took some time to enjoy the sight the strap-on moving in and out of Annabel's mouth. She always had fun making a girl suck cock, and her stepmother was no different.
Thrusting her hips forward until almost the whole shaft disappeared, Carla savored the wide-eyed and somewhat frantic look on Annabel's face. The older woman was clearly overmatched but eager to please, and struggled to take down as much of the girthy pole as she could. She gagged a little and Carla backed off, but Annabel quickly and gamely resumed the effort.
Finally Carla decided it was time for the main event. She pulled out and positioned herself between Annabel's legs, letting the tip of the strap-on rest gently against her stepmother's pussy lips.
Carla loved this part -- in this position she had all the power. Annabel instinctively arched her back to try and get the dildo inside her, and Carla let it start to slide in; she was so wet that there was no resistance whatsoever. A guttural "Unnnnh" echoed from Annabel's throat as the thick head of the strap-on penetrated her.
Again Annabel arched her back, greedy for more, but Carla shifted her weight back and the tip of the dildo slid out with an audible pop. For a long moment it was quiet in the room as Carla stood impassive and Annabel whimpered pathetically, looking up with pleading eyes. Then Carla spoke up in a commanding voice. "What?" she said. "What do you want?"
For a few seconds Annabel was completely lost. She needed it, desperately, right now; but she had no idea what she was supposed to say. And then, all at once, she knew exactly what Carla wanted to hear.
"Fuck me," she said. "Please. Fuck me fuck me fuck me."
"That's better," said Carla, and in one motion drove the strap-on all the way in. Annabel gasped. She had never had anything this big inside her before. For a little while it hurt, but then she started to get used to it, and then it started to feel good. Really, really good. Carla slowly pulled almost all the way out, then abruptly slammed home again in one forceful motion. She grinned as she watched Annabel's eyes roll back in her head.
"Oh, Jesus," barked Annabel.
"What does he have to do with this?" said Carla. She thought that was pretty funny, but Annabel was way too preoccupied to laugh. Parts of her deep inside were being explored, parts that had never been touched before. She felt like every last cubic millimeter in there was being filled up, like the tip of the dildo was pressing up into her stomach. She gritted her teeth and clenched her eyes shut as Carla began to assume a steady in-and-out rhythm.
At this point Carla decided it was time to mix things up a little bit. Taking the chain that connected the nipple clamps in her teeth, she jerked her head back.
Annabel's whole body stiffened as the jolt of pain spread through her. With her eyes closed, she had been taken completely by surprise, and for a second it looked like she was going to cry. Carla almost felt bad, but she knew that Annabel needed a little toughening up if she was going to truly experience the kind of pleasure Carla was capable of giving her.
