Collaborative sex stories let us write the plot together

(Her Secret Fantasy, continued by Anon...)

The next few days are a little confusing. The first night Rachel comes into the bedroom wearing her dressing gown as usual but as she takes it off and slips into bed you see she is wearing the lacy bra and panties she wore the first night you fucked.

She rolls toward you and runs her hand down your chest and stomach. Eventually it comes to rest at your crotch and circles your swelling member. As you push your hips up and let out a groan, your girlfriend shushes you.

“Steady on Ross, I want you to save it all up for me. Remember, I want your biggest load for this. You’re going to need it if you want me to have your baby.”

With that she releases your dick and rolls away.

You spend the rest of the night tossing and turning, resisting the urge to either slip off to the bathroom for a crafty wank or simply jump Rachel’s bones. The next night is a carbon copy. Finally the weekend arrives.

At breakfast Rachel sits opposite you and casually loosens the tie on her robe. She is still wearing the underwear from last night. You can’t help but stare at your girlfriend’s creAmy boobs barely encased in the lacy bra. Rachel notices and smiles as she stands up. The robe slips even further open, giving you an even better view, and your eyes roam down your girlfriend’s curvy body, lingering on her smooth luscious legs as she approaches the front door.

“You know Ross, I was reading an article about how when a man senses competition for his mate his sperm count increases. I think I’ll go and check the mailbox. I know it’s Saturday, but what’s-his-name from next door is usually watering the lawn about now. His wife is a little on the plain side. Do you think he’d want to knock me up?”

With that Rachel walks out the door. You race to the window and watch your girlfriend walk down the drive. Your neighbor does a double take and tries not to be too obvious as he stares at Rachel and gives her a little wave.

Rachel waves back and walks over to him. You watch as they spend several minutes chatting. He is clearly ogling your girlfriend’s body because she has done nothing to secure the robe. At one point the wind starts to gust and Rachel even turns toward it, causing her robe to billow wide open. You can’t believe that your girlfriend is so obviously allowing your neighbor to view her near naked body. Your dick is so hard it’s almost painful.

Apparently deciding that she has given him a good enough look, Rachel waves goodbye and walks back up the drive.

“Well, turns out that whats-his-name is actually Paul. He seems nice. Apparently he has two kids from a previous marriage, both of which were accidents, so clearly his sperm count is pretty good! Your swimmers will really have their work cut out beating those bad boys!”

In total confusion, you blurt out “What? Bad boys??” As you follow Rachel into the bedroom.

As she finishes putting on her yoga pants and sports bra, she pauses, laughs and points at your crotch. “Don’t worry Ross, from the looks of it you’re working on a sizable load yourself! Anyway, I’m off to yoga. I bet Dan is pretty potent too. He’s pretty commanding when he instructs his girls! I bet his boys would take some beating as well!” Rachel kisses you in the cheek and walks out the door.

Your mind spins. What does Rachel mean? Is she just stirring you up? Or is it what it sounds like — does she really mean she wants you to compete with other guys to impregnate her?
