Go for it

She must have seen a look flash across David's face. "Hah! These sluts don't even give you anal? I do have something to teach them after all." She looked around the harem, "got any lube?" She looked at David, "I could go dry, but guys usually think the slip-n-slide feels better."

There was a bottle of lube in the original collection Maria and Julia had brought to the apartment, but all of the girls were so naturally juicy, it had been unused. Maria fetched it.

As Cynthia got on all fours, a glob of cum dripped from her face. She looked back at David, "well? Go for it."

David pressed his cock against Cynthia's eager ass. When he hesitated, Cynthia demanded, "come on. I'm not one of these prissy girls you usually fuck. Use my ass to get yourself off."

He wasn't happy hearing unkind words about his girls. He thrust his cock against her, pushing deep into her asshole. She grunted in approval.

David loved the feeling of her tight hole gripping his cock. He did exactly what Cynthia had asked: he pumped his cock hard and deep into her asshole, using it to make himself cum.

The other girls were all carefully watching the display Cynthia was putting on for them. Hands gripped tits and explored pussies as they did.

Just as he was about to cum, David pulled his cock almost all the way out of her before quickly slamming his full length back inside. She grunted, "oh fuck yes" when he did. He held himself deep inside her, enjoying the feeling of her ass gripping the base of his shaft as he pumped her full of cum.

When he was finally done with her, he pulled out and took a good look at her stretched, lube-covered ass.

Without getting off her hands and knees, she turned to the other girls, face still covered in cum and said smugly "see? That's how you do anal." She turned to David, "I think you should keep me around. These girls need some lessons."

He threw a cloth at her face and scoffed. "You think that's going to get you captured? That's not the way things work around here." She had turned to sit on the bed and had started wiping his cum off her face.

He saw the smug look on her face flicker and continued, "My girls are very good to me, and I expect them to be good to each other. How about this? If you can do a good enough job getting them off, then maybe I'll consider capturing you. Maybe."

Despite herself, Cynthia's eyes lit up momentarily.

David continued, "but if just one of these girls tells me you're less than 100% dedicated to making them cum, you're out."

Cynthia smiled, just barely. David concluded, "I'll give you a day. You'd better prove how much you want it."

Cynthia's eyes left David. The first girl her eyes landed on was Julia, who she tackled. Cynthia's fingers were being pushed inside her before they even came to rest on the mattress.

That night, David fell asleep to the sounds of Cynthia feverishly licking Sarah. When he woke up, he opened his eyes to see her fingering Maria while sucking her tits.

When the verdict was in, the girls decided that Cynthia definitely had more to learn about pussy licking. Cynthia scowled at the appraisal. They unanimously suggested Julia as a tutor. Julia blushed.

Cynthia was captured.

The girls had mixed opinions about anal.

Chloe had a new way to get herself and David off, and was thrilled.

After a few experiments, Sarah's summary was "but it feels so good in my pussy."

Julia could take it or leave it, but found her new favorite thing in the world: being on the bottom of a 69 with Maria and watching from just inches away as David's cock filled her girlfriends ass. Every thrust of David's cock would push Maria's pussy into her mouth, and she loved it. Both David and Maria were happy to help.

When Julia was particularly lucky, David would pull his cock out of Maria's ass and shoot his load all over her pussy and Julia's face. Julia was extremely enthusiastic about the cleanup process after he did.
