She's hesitant

"Oh!" Her exclamation of fear and surprise makes you pause. Her shoulders hunch and she covers herself nervously. "Please, Sir, I've never been with a man. I don't know what you want." The fact that Sandra calls you 'Sir' instead of Stephen is the only indication that she is still playing the role of the beautiful maiden of Venus.

"What do you think I want?" Sandra clearly had been filling in many of the gaps left by the plot of the movie, because there is no hesitation as she speaks again.

"We learnt all about males in school." Her head remains bowed, but she is speaking clearly enough that you can hear her without difficulty. "I know that men are driven by their carnal lusts and primitive biological need to spread their genes." The way she is crouching timidly at your feet wearing nothing but her cotton briefs, makes it difficult to refute her statement. If you were one of those stranded Earthmen on Venus, you would definitely want to do exactly that, but that's not all sex is about.

"What about feeling good?" You ask softly, "don't you think that sex could be pleasurable?"

"For the man, I guess." For the first time since taking her knees, Sandra looks up at you, brushing her hair back behind an ear with the hand not wrapped around her bosom. "For woman sex is a painful, degrading experience. Our teachers were very clear about that, Sir." When she sees the look on your face, Sandra continues with this alternative, man-hating reality with earnest determination. "That's why males are so much bigger and stronger than females, so the female cannot twist away while her breeds her." You cannot hide your smile when it becomes clear in your mind what you are going to do with this lovely virgin.

"No, my Dear, you have it all wrong." Taking her hand in yours you lift her gently to your lap. "It's true that the first time there can be a little pain, but I'm going to make you feel amazing too." As you speak, you position her on your thighs, so she is facing away from you and your arms are free to explore her soft body. Her legs press tightly together, and she is still trying to protect her modesty as best she can; she is clearly not ready to meekly surrender even when she starts to respond to your caresses.

"What?!" Sandra squirms on your lap as your hands stroke her bare flesh. "No, stop it. Only a woman should touch me like this." Her hands protectively cover her most private parts, but that still leaves a lot of territory to explore. One hand strokes her thigh while the other tilts her head to allow your lips to brush lightly against the soft warm skin just under her ear. Sandra's protests weaken into soft gasps and whimpers, but as you nuzzle the sensitive spot just under her ear her back arches and her knees start to spread.

"Let me show you what you girls have been missing out on all these years." Turning her head, you are able to reach the corner of her mouth and soon she twists a little more, so your mouth is fully on her full lips and the kiss deepens. You never could have imagined that your first kiss with this buxom beauty would come after she's been stripped of her clothes and you've had a chance to feel her up, but it is a good first kiss all the same. It is not a demanding, instead you let her take the lead. It is a good choice because it is not long before her lips open in an unmistakable invitation and your tongues are dancing inside her mouth.

"Stephen, this is amazing!" Sandra's voice is low and breathy, "if I were one of those frightened young women sent to your rooms, I'd have to let you kiss me like this." Her face reddens a little more, "I'd have to do anything you wanted, wouldn't I?"

Well, that pretty much is your fantasy, isn't it? To have a bevy of innocent young women waiting for you to fuck them; beautiful and powerless maidens who have to do everything you ask.

"Spread your legs." You pause a beat and then add in a much firmer tone, "now."
