You do

Now that you're so close to the main event, Allison seems to be getting a bit shy. You're too turned on to be shy. "I kinda thought," she whispers, "this way we could start out with something a bit more familiar, and..." She's talking too much. You know a good way to stop that.

This kiss isn't like the others you've shared. The passion, the emotion, the intimacy are all still there, but now stronger even than any of those is the raw, wild, animalistic need. You need her, you need her body like you need food, air, or water. You need to please her, to explore her, to possess her, to claim her. And you need her to do all of those things to you. You can tell that she needs you too, but not in quite the same way. Her need is softer, more subdued, yet just as real. She's unsure of herself, and she needs your help to understand the need she feels.

You reluctantly pull away. Your hands are cradling her head, and the fingers of your right hand have found their way back to her earlobe. Her eyes flutter open after a few breathless moments. "That wasn't exactly what I meant by something familiar," she says, smiling broadly. You reach out and take the strap-on - Allison lost her grip on it during the kiss, but it's still dangling by a strap caught on her wrist - and start to put it on. "Let me help you with that. I think I know how it works."

Allison drops to her knees to fiddle with the straps for a bit, and you can't help but notice how similar this looks to the first time she ever sucked you off. You lean back, enjoying the memory. As she finishes securing the device, she looks up at you mischievously, and you can tell she's thinking the same thing. You're still surprised, though, when she leans forward and starts to lick the toy on all different sides. You realize she's doing it for lubrication, and she isn't actually stimulating your body, but still... the visual image of her smiling up at you as she licks your fake cock, framed by your taut, perky nipples and your long, supple legs is... incredibly erotic.

You can't wait any more. You spring to your feet, lift your girlfriend up and throw her onto the bed. At least, that's what the male part of you wants to do. You can't actually lift Allison any more, as you learned earlier, but she yields to your gentle touches as you guide her onto the bed anyway, so it's just as well. Soon enough she's on her back, with her legs up and her feet resting on your shoulder. You push the toy cock into her gently, just like you would have started out with your real one. Allison is a bit tense at first, but she relaxes quickly enough. Finally, after about a minute of slow thrusting, she reminds you: "the switch to turn it on is at the base."

You had forgotten it was a vibrator. After a quick inspection you find the switch and push on it. The switch seems to stop halfway, but the toy does start to vibrate. Allison lets out a long moan of satisfaction - you hadn't pulled out all the way - before answering your unspoken question: "It has two settings." For a moment you think she's going to explain more, but she gives up on talking as soon as you start thrusting again. Oh well.

You thought that you were satisfied with pleasuring her first and waiting for your turn, but now that the plastic base of the harness is vibrating against your outer lips, this is a lot more enjoyable than you anticipated. You quicken your thrusts. Her feet fall from your shoulders, but rest comfortably around your hips. She curls one foot around your leg to pull you against her. Her breasts jiggle hypnotically beneath you, and you find your hands irresistibly drawn to them. You roll the flesh gently between your fingers. Allison moans again, this time short and higher pitched, almost like a cute little squeak. Then you feel her hands on your own smaller breasts, reciprocating your attentions from a moment before. Your hands drop down towards her hips, gripping her so you can thrust harder, deeper.

Allison reaches up to wrap her arms around your neck pulling herself up and you down towards her. You meet in a kiss, but you can't hold it while thrusting so insistently. Instead you nibble her lips as she squeals in pleasure. Before long, her squeals pick up in frequency and volume, until her whole body shudders in climax. Looking down at the blissful expression on her face, you cum too, though not as hard or as long. You pull out of her as you both come down, but then your legs give out from exhaustion and you collapse onto the bed.

You lie there beside of her for a long time as your breathing slows back to normal. Then she sits up and reaches to start undoing the buckles on your hips. You're disappointed for a moment before she turns to you and smiles, and with just two words makes your pussy flood all over again:
