Summary: Cass asks GoGo to take her on a joyride to feel young again, but she doesn't suspect that the younger woman has other plans.

When Cass asked GoGo to take her out on a joyride to feel young again, she thought it'd just be a ride on her motorcycle through San Fransokyo. Maybe take a few scenic routes, stop by a food truck for a bite to eat, you know, normal joyride stuff. She hadn't expected GoGo to come decked out in the hottest biker gear she'd ever seen. And she definitely didn't expect to be so turned on by it.

It was just a black tank top, showing off a delicious bit of cleavage and her midriff, her belly button piercing clearly in view. Her black jeans clung to her in all the right places and Cass would have let GoGo step on her in those boots. A studded leather jacket was slung over her shoulder, and Cass couldn't look away as GoGo shrugged it on. It shouldn't have had such an effect on her, and yet she suddenly felt warm. And massively underdressed.

"Bet you've never had a ride like this before." GoGo patted the handlebar of her bike, the corner of her lip turned slightly upwards.

"Yeah, no," Cass replied, eying the vehicle with caution. "Not in decades. And my old bike wasn't nearly this sleek."

"Nervous?"

She did a cute scrunch of her nose. "Just about falling off."

GoGo smiled—or did she smirk?—and Cass felt her heart jolt. "I'll be behind you," she assured her. "You'll be fine."

Cass tried not to let her mind get swept away by thoughts of the last time GoGo was 'behind her'. It had just been a one time thing. A sinful, shameful, incredible one time thing they'd never repeated. Not any of the times GoGo had been over since, not when they ran into each other at college events. One and done. Well, technically they had gone for way more than just one round, but that's beside the point.

"Ready to go?"

She swallowed, trying to return some moisture to her mouth. Was it just her, or was GoGo looking at her… differently? "Yup."

GoGo patted the seat. "Hop on."

Cass was just in a t-shirt and shorts, and the latter rode up slightly when she mounted the vehicle, showing off more of her thighs. Heat rushed to her cheeks once again, especially when she could sense GoGo's eyes on her. This woman would be the death of her.

GoGo climbed on behind her, and Cass found herself trapped. Their legs brushed against each other and GoGo's chest was completely flushed against her back as she started the bike. When the engine revved, Cass jolted in shock and nervous energy. The whole thing vibrated, and she would feel it in her bones, in her core, between her legs.

Maybe this was a bad idea.

GoGo's fingers dug into the area between her hips and waist, and Cass willed herself to calm down. This was normal. This was how two people ride motorcycles. There was nothing more to it than that.

"Do you remember how to do this?" GoGo asked. She was close enough to be heard over the thrum of the engine. She didn't even have to raise her voice.

"I think so." The last time Cass had ridden a motorcycle was when she was in college, but she hoped it was like riding a bike, in that you never really forgot.

"Only one way to find out." Cass could hear the smirk in her voice.

The older woman took a deep breath, which unintentionally pressed her back harder against GoGo's chest, before gripping the handlebars and setting off. Excitement coursed through her as she felt that first rush, the start of a drive. It had been too long. She missed it.

Cass tried to focus on the scenery around her, taking the route GoGo had programmed into the GPS system, but she couldn't help but notice GoGo's fingers digging into the material of her shirt, or her breath hot against her ear. Her heart raced. She convinced herself it was the adrenaline from the ride.

"This is fun," GoGo commented when they were stopped at a red light. She'd somehow moved closer. Their bodies were practically flush. "I like hanging with you, Cass."

"It is," Cass agreed slightly shakily. "It's been a while." Since she rode a motorcycle, and since the two of them have hung out one-on-one.

"And… the last time we did was fun too."

Cass gulped. "It… was."

GoGo chuckled. "We should do this more often."

Cass inhaled sharply, shutting her eyes. She swore GoGo had shifted her hips slightly forward. She could definitely feel something more. That and the feeling of the bike purring under her… God…

"Light's green," GoGo said evenly, pulling back slightly.

She held a white-knuckled grip on the handlebars, propelling them forward once again. Get a grip, Hamada, she thought to herself. She'd just wanted to go for a youthful joyride. It didn't matter that GoGo was making her feel young again… in other ways.

The wind rushed through their short hair while they were still in the city centre. Cass couldn't wipe the smile off her face, especially when GoGo held onto her a little tighter every time she took a harder turn. Slowly, the GPS led them to smaller backroads, sparsely populated. "You can slow down here," GoGo instructed, a hint of laughter in her voice. Cass obeyed immediately.

"What exactly is this route you're taking me on?" she asked. She couldn't see that GoGo was grinning behind her.

"Oh, you know…" Her hands drifted lower, resting against the swell of her hips. "Somewhere for a bit of privacy."

The bike stuttered to a stop, along with Cass' breath. So much for a one time thing.

Was this really happening? They were out in the open. She glanced around, noting that the area they were in seemed fairly deserted. There wasn't another person in sight. Still, they were in public. What did GoGo even plan to do?

"GoGo…" She whimpered when GoGo cranked up one of the gears on the bike. Even though they weren't moving, it just made the engine vibrate with even more intensity. Cass raised herself off the seat slightly to alleviate some of the pressure while she worked everything out.

"Is there a problem, Cass?"

God, she just said her name, but Cass loved how GoGo said her name. "Are we really doing this?"

"Depends what you mean by… this…" Her fingers ghosted over her ass. Cass wished she'd just grab it outright.

"You know what I mean," she replied sternly.

GoGo's laugh was a low, guttural sound, sending goosebumps up and down Cass' arms. "All I know is that I've been thinking about fucking you on this bike for so long." Cass gasped when GoGo grabbed her hips once more, fingertips brushing her thighs. "But for now, I think I'll just make you cum on it."

"You'll—oh!"

Cass was guided until her centre was pressed right up against the bike seat. The engine roared underneath them, sending the most delicious jolts of pleasure through the older woman's core. Even though she was still fully clothed, she could feel the vibrations right where she needed them most.

"F-fuck," she choked out, hips bucking against the seat. "Are you sure this is a good idea?"

"Do you want me to stop?" GoGo asked, loosening her grip before Cass firmly protested.

"God, no."

The younger woman smirked, leaning forward to kiss the back of Cass' neck coming round to the side of her jaw. "No one ever comes round these roads," she whispered. "So don't hold back. I love how loud you can get." Her hands traced Cass' body, slipping underneath her top. She was still fully covered, but anyone who saw them would have no doubts about what they were doing. GoGo let out a satisfied sound of surprise when she was immediately met with bare skin. "No bra?"

"I find them… constrictive…" Cass tried to say, voice broken up by lustful moans when GoGo began toying with her nipples.

"Hm. I'm definitely not complaining." Cass' boobs were perfect. They were full and round and felt like clouds in her palms. She still had wet dreams about the time her cock was pillowed between them, the perfect tit fuck ending with her cumming loads all over them. "I love your tits, Cass."

"Yes, keep touching me like that, baby." Her voice was wound tight with pleasure. GoGo's legs intertwined with hers, their ankles crossed, pinning her down firmly on the seat. Not that Cass was trying to get away. The feeling between her legs was too damn good.

"I wonder if this is what you used to do when you rode," she teased. "Putting your bike into high gear. Not even going anywhere, just sitting in your garage while you rub your clit up against the seat. You'd be in private so you wouldn't even need to worry about pants. Leather seats are waterproof, after all. And I'm sure you'd be soaking."

Cass couldn't even deny it. There was definitely a wet spot on her panties, if it wasn't showing on her shorts already. The tremors were incredible, but she needed more. More to push her over the edge. "Please…"

"Please what?" GoGo liked to make her beg for it.

"Touch me."

"I am." She pinched her nipple for emphasis.

"GoGo." Cass tried to put on her firm aunt voice, but her voice wavered and betrayed me. "I'm so wet. I'm so close. Please, I need more."

GoGo considered keeping the older woman on her toes. Making her wait for it. Maybe even turn off the engine so the edge of her orgasm faded. But she sounded so desperate, and as much as GoGo enjoyed teasing her, she had a soft spot for Cass. "Okay, okay," she chuckled, using one hand to unbutton Cass' shorts while the other continued to play with her tits, Cass spread her legs wider on instinct and GoGo pressed her hand up against her warm centre. "Jesus," she groaned.

"You picked me up looking like that then teased me for what felt like ages. That's on you," Cass jibbed, trying to hump up against GoGo's fingers already. The younger woman didn't keep her waiting any longer, much to her relief. She slipped two fingers into Cass' waiting heat, curling them in search for that perfect sweet spot within. Cass let out a loud moan of pleasure, and even though they were far away from the rest of civilisation, GoGo wondered whether her steadily growing volume would eventually draw some attention when given enough time.

"You sound so hot, Aunt Cass. Keep moaning for me." Neither of them even noticed the slip, or they did but didn't feel the need to address it. GoGo's aunt kink had been discovered the last time they were together, and neither had a problem with it. If anything, it just turned them on even more.

"I'm gonna cum, GoGo!" Cass cried out when GoGo's fingers found that perfect place that sent her spiralling. She could still feel the rumbling of the engine, GoGo's hands toying with her breasts, her lips on the spot on her neck where her pulse raced beneath her skin. Cass reached behind her, grabbing helplessly at GoGo's jacket while her breathing stuttered and she came messily in her shorts. Her mind was blank with pleasure, and even though they were alone, she almost wished someone had seen them. She needed the whole world to know how good GoGo was making her feel. She almost felt like the performance was wasted on empty roads.

GoGo continued to caress her body in all the right places as she rode through her orgasm, whispering words of praise and encouragement that Cass couldn't even focus enough to register. Eventually, she stopped, giving Cass a moment of respite. She brought her fingers to her own mouth and waited until Cass turned back to look at her before diligently sucking the older woman's juices off each one. Before Cass could say anything, she was pulled into a steamy kiss, lips locking, tasting herself on GoGo's tongue.

"Feeling younger yet?" GoGo asked teasingly when they got a break.

Cass' nose crinkled in the cutest way when she laughed. "With you? Always."
