Amy approached Rosa's apartment, pausing before she knocked, nervous about what was to come. She had been given very strict instructions about what she should wear: jeans, T-shirt, and boxers. No girly knickers or bras allowed. Feeling slightly self-conscious, she adjusted herself, almost jumping as Rosa opened the door.

"Come in."

"Thanks."

Amy stepped in and looked around. Despite having seen Rosa's previous apartments, she was still shocked by how light, spacious, and welcoming it was; in her head Rosa was still the terrifying, black-leather-wearing character she had met when she first transferred to the nine-nine. The bedroom was visible through the hallway, a perfectly made bed in a red and black theme. I guess Rosa was a little bit dark and scary.

Taking Amy's head in her hands, Rosa kissed her, pressing her back against the door. Taken by surprise, Amy dropped her bag and whimpered gently, her cheeks flushing. Caught completely off-guard by the intensity of Rosa's advances, she struggled for breath, pawing at her partner's body, until she was released a few moments later. Feeling her T-shirt being pulled upwards, she lifted her arms and allowed her breasts to bounce free, continuing to snog Rosa as she undid her jeans and pushed them down over her butt. Rosa removed her own top and jeans, exposing a black lace set of underwear and bra.

"You said I wasn't allowed those!"

"My rules. You got a problem?"

"…no…"

"Good. Now here's what's going to happen. You're going to go and get into bed, make yourself comfy, and you're going to call me "momma". Got it?"

"Mm-hmm"

"What?"

"Yes, momma."

"Off you go." Rosa slapped her butt hard as she walked towards the bedroom, and smirked. This was going to be fun!

Amy tip-toed over to the bed and did as she was told. Rosa slid under the covers on top of her, pressing her body as flat down as she could, kissing Amy. Reaching down with one hand, she felt Amy's cock through her boxers, rubbing along its massive length down to her balls, cupping them gently. Rubbing up and down, up and down, she felt Amy's cock get bigger and harder until it wouldn't fit into her undies anymore and Rosa was forced to remove them. Pulling her boxers down, she took Amy's member in one hand and began slowly massaging it from tip to balls – eliciting an "oh, momma!" from Amy. Lowering her face to Amy's hips, she opened her mouth and gorged herself on her partner, taking as much in one gulp as possible, and masturbating the bits she couldn't reach. Flicking her tongue over the tip, sucking as hard as she could drove Amy crazy, arching her back and screaming out, thrusting into Rosa and holding her head in place and she was forced closer and closer with each lick. Feeling her lover rub her sack sent Amy straight over the edge, clenching her balls and pressing as hard into Rosa as she could, she sent thick ribbons of cum shooting out of her, only to be immediately swallowed. Suckling for as a long she possibly could, Rosa felt herself almost edging from the arousal. Her mouth overflowing, cum streaming down her chin, she squeezed out one last drop of spunk and felt Amy collapse – her nuts completely drained.

Rosa crawled back up the bed and wrapped an arm around her boytoy, and Amy rolled onto her side and snuggled tight, resting her now-flaccid dripping cock on Rosa's panties.

"And what do you say?"

"Thank you, momma."

"Good girl. Now rest, that is not the last load I'm rubbing out of you tonight. Momma's horny."

30-40 Minutes Later

Amy stretched out, arching her back and rubbing her cock against Rosa.

"How you feelin' down there?"

"I think I'm ready…"

Rosa twisted around so she was straddling Amy and reached down, gently grabbing Amy's semi-erect shaft – feeling it twitch.

"Can I touch you?"

"Excuse me?"

"May I touch you?"

"…"

"Momma?"

"That's better. You may."

Amy lifted a hand, clumsily fingering the gap between Rosa's legs.

"You've never done this before, have you?"

"No, momma. I've only ever been with people like me."

"In that case, I know what to do with you. Have you ever been penetrated?"

She shook her head.

"You wanna try it?"

"I… I guess…"

"Get on your hands and knees."

Rosa climbed off her and reached into the bottom drawer of the nightstand as Amy did as she was told. Out of the drawer she pulled a strap-on, a butt plug and a bottle of lube. Lubing up the butt plug and reaching down her panties, she gasped in pleasure as it slipped into place. Tying the short, thin dildo around her waist, she lubed that up too, and positioned herself behind Amy.

"You ready? This is probably gonna hurt."

"Yes, momma."

She pressed her latex dick against Amy's opening, gently but firmly pushing inside, careful not to go too far. Once the tip was in, Rosa started ever so slowly thrusting the end in and out.

"What do you think?"

"It's weird. It's kinda uncomfortable, but also… kinda nice…?"

"You want me to keep going?"

"Ah-huh."

"Excuse me?"

"Yes, momma."

She slowly but surely thrust all the way to the hilt.

"Aaahhh…"

"Kneel up."

Rosa began thrusting faster and more aggressively.

"You like it?"

"Aah… yeah… aaaaaahhhhh"

She reached around and took Amy's cock in one hand, wanking in time with her thrusts.

"Tell me you like it."

"Fuck my ass, momma!"

"You're a good little slut."

Faster and faster she wanked, keeping a regular rhythm pounding Amy's ring. Her legs started shaking, and her breathing got more rapid and shallow. She cried out in pleasure-

"I want to cum, momma!"

"Not until I say."

"Pleeaaase…!"

"No."

"I'm desperate… I can't hold it…!"

Rosa stopped suddenly, releasing Amy's shaft, and stripping her of the rubber cock. She fell forward back onto her hands; her legs couldn't support her, and she slid down onto her tummy.

"Please, momma, let me cum…" she groaned. This earned her a hard spank.

"Not until I say. Now," she got off the bed, removed the strap-on, and reached again into the drawer. "Your turn to make momma cum." She handed a back massager to Amy, who rolled onto her back in time for Rosa to straddle her again. "Massage my clit." Amy switched the vibrator to the lowest setting and pressed it gently against the black lace panties. "That's a good little girl…" she whispered, laying her head next to Amy's, nibbling her ear.

"Why don't you take your panties off for me, momma?"

"I will when I cum. You have to earn it. I'm already making a mess in my panties, be a good whore and turn it up…"

Feeling the vibrations increase, Rosa arched her back in bliss and moaned into Amy's ear. She turned the vibrations up again, causing Rosa to thrust down against the vibrator, wetting in her panties.

"Are you close, momma?"

"Uh… huhhhh…"

"Cum for me."

Rosa came hard, screaming to Amy's ear, thrusting her hips hard against the vibrator, ejaculate dripping from her panties. Several seconds went by, a seemingly endless shower of screams and cum, until Rosa finally collapsed, falling on top of a now very wet Amy.

"I've never seen a girl cum like that before, making a mess."

"I always have messy orgasms; I wish I didn't."

"I think it's hot."

"Shut up and take my panties off."

Delighted, Amy ran her hands up Rosa's back, and unclasped her bra, throwing it aside. Grabbing her panties by the hips, she pulled gently down, freeing Rosa's pussy, a long, thin strand of cum trickling down.

"I think you've been a good enough little slut to earn your own butt plug."

"Yes please, momma! I love having things in my butt!"

Rosa reaching into the drawer and lubed up another, bigger, butt plug and eased it into Amy's ass – eliciting a squeal of surprise and joy.

"Now you have to fill me up with your cum. Can you do that?"

"Ohhhh momma!"

Taking this as an affirmative, Rosa grabbed the huge cock and carefully impaled herself on it, squeezing precum out of Amy and oozing her own spunk. Thrusting her hips up and down, she took Amy's full size, both of them exhaling forcibly.

"Please fuck me harder, momma!"

Rosa obliged, pushing down harder and faster on Amy's throbbing cock. Several minutes passed, the two lovers getting closer to orgasm with each thrust.

"Touch my clit…"

"I'm getting close, momma. I'm going to fill you up…"

"I said touch my clit, slut!"

"Yes, momma!"

The magic touch did it, Rosa screamed out in pleasure, thrusting faster and erratically as she neared orgasm.

"Cum now, I want your cum in me!"

"I'm close… really close… right… there…!"

For the second time, Amy felt her balls tighten and her cock twitch uncontrollably as thick ribbons of cum shot out into her partner. Rosa felt the hot, sticky treacle shoot deep inside her, and she came instantly, her clit sending wave after wave of pleasure to her brain, her pussy spasming and contracting down on Amy's beautiful, engorged cock. Both of them moaning and shuddering in ecstasy, they rode out their shared orgasm until it hurt, finally stopping so that Rosa could roll off and collapse next to Amy.

"Well that was amazing."

"It was… thank you, momma."

And so, the two lovers lay, recovering from their evening of debauchery. Cum poured out of Rosa's pussy, onto the bed. Amy's cock softened and dribbled onto her tummy, both thoroughly used and exhausted.
