She recovers quickly

"Wow, Stephen!" Sandra is still breathing hard as her body twitches on your lap. "It felt so good when you touched me, but when said that thing about Earthmen coming to Venus and knocking up me and all my friends, it was so wicked."

"I know," you stammer uncertainly, "I shouldn't have -" before you can even finish the thought you are cut off by the excited Library Science major still panting on your lap.

"Of course you should!" Sandra interrupts you with a fierceness you aren't expecting. "That's the fantasy, right? An unending supply of innocent virgins to claim with your manhood?" To your surprise she readjusts her legs, so she is straddling your waist with her arms resting on your shoulders and her face is just inches from yours. In this position her breasts are so close to your chin that you can smell the lingering scent of her bodywash and feel the warmth of her breath on your ear.

"I wish I could make you feel as good as you just made me feel..." she bites her lip nervously and then makes a shy offer. "Maybe I could try and give you a hand-job?" Sandra's naked body squirming against you is the most amazing lap dance you can imagine; it seems like a letdown to have her get you off with her hands that way. You keep her on your lap, kissing her and caressing her naked flesh for several minutes. As much as you'd like to bury your face in her tits again and kneed the soft flesh with your hands you keep away from her breasts and concentrate on making the kissing gentle and caring. After the weirdness of the roleplaying, it is important that Sandra knows that you care for her, and not just some space maiden from a sci-fi movie from the 50's.

Sandra, however, refuses to drop the idea. In between kisses she murmurs softly in your ear about how the countless women of Venus needed the Earthmen to repopulate their planet. "You could have anyone you felt like, maybe even lay that sweet princess on her back and spread her legs. You could sire the next generation of Venusian queens?" She seems even more excited by this stupid fantasy of yours than you are. Most of all though, she seems guilty about not 'putting out'.

"Are you sure you don't want me to use my hands, Stephen?" Her fingers slide between the two bodies and experimentally brush the head of your cock where it is tenting the sweatpants.

"I've never tried anything like this before," Sandra confirms what Vivian told you about her roommate's lack of experience, "but most of the ripe young maidens sent to your chambers haven't ever even seen a man until she is given to you, so that's about right."

"I've got an idea we can try." You tell her, as you lift her chin gently so you can plant a gentle kiss on her trembling lips. "If you trust me."
