Rihanna joins the harem

"OH, YES Master! I obey gladly!" - Rihanna chanted and assumed the position Michael told her to. She looked very sexy and seductive.

Michael approached Rihanna. He stuck his fingers into her folds, making her moan loudly. The flesh of his palm was pressed against Rihanna's swollen clit, and her pussy was on fire from the feeling of her Master's fingers inside. She rocked her hips against his hand and his fingers slid fully in and out with no resistance.

Her legs were trembling and she moaned long and low, occasionally yelling out things like "OH YES...MASTER...FINGER YOUR DIRTY KINKY SLUT...". Michael took his fingers out, then suddenly stuck them in again; the sensation sent a shock up Rihanna's spine and she gasped like she'd been pierced with an arrow. Michael began thrusting harder and harder.

The pleasure built and built, her pussy felt hotter and hotter with every rub of Michael's fingers on that sensitive flesh inside. Rihanna's legs were stiff, she gritted her teeth, her hips stuttered before faltering in exhaustion as a wave of orgasm struck. She fell back, panting. They both needed more.

Michael suddenly remembered his watching wives. "Girls, you do remember the rest of the slaves are yours to use freely?"

"Oh! Yeah, of course!" - Emma said, snapping back to reality. Chloë nodded. They each went off to find a **** to fuck.

Michael, however, went back to focus on Rihanna. He grabbed her thighs, running his finger over her inner thigh before positioning his cock at the entrance to Rihanna's pussy. He rubbed his head against her slit, moisture gathering. He parted her lips and slid his cock in. A loud moan came from Rihanna's mouth as she felt her Master's dick penetrate her.

"Do you like that?" Michael growled. "YES!!! YES MASTER!!! I LOVE IT!!!" - she moaned.

Rihanna continued to moan in ecstasy as the pleasure began mounting. With a patronizing slowness, Michael started to slide his huge dick in and out of Rihanna's pussy. As his full length filled her again and again, she squeezed the walls of her pussy. Rihanna latched onto Michael's torso with her legs, and he began to pump his cock in and out of her pussy faster and faster, seemingly driving it deeper and deeper with each stroke. Rihanna moaned and grabbed onto the couch beneath her, her breasts shaking more and more. He took his arms off her thighs and began fondling her tits, causing her to moan even louder.

Grabbing her thighs once again, Michael pounded harder than ever, grunting as he invaded Rihanna's body with his massive cock. With her ass positioned just above the surface she was lying on, Rihanna began to thrust herself towards Michael's powerful lunges. Grabbing her own bouncing boobs this time, she screamed, "YES MASTER! THAT FEELS SOO GOOD MASTER, FUCK ME HARDER, POUND YOUR OBEDIENT SEX **** MASTER!" Duly obliging, Michael slammed his dick into her hole, feeling the cum begin to build up inside of him. His balls slapping Rihanna's ass with his frantic motions, she let out a long yelp and began to orgasm wildly, her pussy squeezing onto Michael's cock, which sent him over; he began to cum as well. Just as her orgasm began to die down, Michael shoved his fingers back into Rihanna's pussy, pumping them quickly, sending her right back into another wave of orgasm.

"Thank you...Master..." - she heaved and panted, - "Thank you...for initiating...your little slut...into your harem...Master..."

"You're welcome, slut!" - Michael said, "Now go join the others - the alphas will provide you with **** attire and tell you about your household duties. Oh, and call your mistresses to the Master bedroom on my behalf."

"Of course, Master! I obey!" - Rihanna chirped eagerly and ran off, round ass bouncing behind her.
