Cynthia goes to see Vanessa in the guest room

Mark acts casual when he reunites with Cynthia by the fire pit, giving her an easy peck on the cheek as though he didn't just humiliate himself sexually while trying to cheat on her. He tells Darren and Jade the tale of how Vanessa was feeling a bit sick and took a nap in one of the guest rooms and woke up projectile vomiting onto the bed.
"I got her into the shower, and the stuff she was wearing is in the laundry along with the bedding," Mark lies, "I think she's just had a bit too much booze and sun."
"Classic Vanessa. I guess she'll be staying over tonight. I'll bring her some sheets and clean clothes," Jade makes a face, "and maybe a bucket."
"I'd better go and see her too," Cynthia says. It's in character - Vanessa loves being the center of attention when she's sick, injured, or sad. Jade's not wrong, having some sort of crisis which demands everyone's attention and drags people away from the fun IS classic Vanessa. It just so happens that, at least this one time, it's a total lie.

Vanessa's sitting naked on the floor by the toilet when Jade and Cynthia enter the bedroom with the supplies. Along with the things Jade mentioned, Cynthia brings a glass of cool water.
"At least nothing got onto the mattress," notes Jade, "Wanna check on Vanessa while I make the bed?"
Cynthia nods and enters the ensuite, closing the door behind her. She takes off her cardigan and wraps it around Vanessa's shoulders.
"Heyyy," she says softly, comfortingly, "How are we going?"
"Oh, you know," replies Vanessa, grimacing theatrically, "feeling shitty."
"Yeah, I know baby," Cynthia says, rubbing Vanessa's back. You should feel shitty, she thinks, you're a shitty friend.
"I think I'm done throwing up, at least," Vanessa says, "Is everyone mad at me for ruining the party?" This is another classic Vanessa line. Cynthia had better play the same part she always does and reassure her.
"Noooo, Van, no," Cynthia assures her in a fawning tone, "Nobody's mad at you, they just want you to be okay."
Vanessa rests her head on Cynthia's shoulder and they stay that way for a while, until Jade softly knocks on the door to tell them that the bed is ready. Cynthia helps Vanessa up and supports her as she makes her way over to the bed, knowing all the while that the whole thing is an act. Vanessa clambers into the bed and holds the covers back for Cynthia to get in after her.
"Stay with me? Just for a bit?" Vanessa begs.
"Okay, just for a bit," Cynthia replies, slipping in beside her so-called friend.
"Can you turn out the lamp? It's hurting my head," Vanessa frowns, so Cynthia complies.

For a few minutes they just cuddle together under the covers, Vanessa's naked body pressing against Cynthia's swimsuit-clad one. After a while, Vanessa speaks.
"I think I need some advice," she says.
"Sure, baby, what is it?" Cynthia replies, as expected. There's a long pause.
"I've been seeing this guy," starts Vanessa. No way! thinks Cynthia, Is she seriously about to ask me for advice about her relationship with my husband?
"Okay..." she prompts Vanessa to continue.
"So, I've known him for a while. There's always been chemistry there, and we've come pretty close before, but it wasn't until a few months ago that we started actually sleeping together, right? And we fit together so perfectly, it's like we were made for each other. It's not just sex either, I really like him," Vanessa says.
"He sounds great. Would I know him?" Cynthia asks.
"Nah, totally different circles," Vanessa replies quickly, "And yeah, he IS great. And the sex is great, or at least it was..."
"Was?" Cynthia asks, hiding her disbelief at Vanessa's audacity.
"Yeah..." Vanessa pauses, as though she's looking for the right words, "Recently, though, he's been... having trouble... well, you know. Getting hard."
"How much trouble? Like, it takes longer than usual?"
"No, like he can't get hard at all. I've tried everything. I've put his limp dick in my mouth and sucked until my jaw hurt, but eventually I have to give up and it feels like we've both failed," Vanessa complains, "And then, the other day, he finally got hard, right? And then the moment he got it inside me he went soft again AND THEN immediately came."
"If you're trying really hard to turn him on, maybe it's just... stage fright? Like, he's so nervous that he's not going to be able to get hard for you that it actually keeps him from getting hard?" Cynthia suggests, "That would explain the premature ejaculation, too. Maybe you need to just... take it easy, and try not to draw attention to it?"
"Yeah, I guess," Vanessa sighs, "It sucks though, because I have a pretty high sex drive, and he's always been able to satisfy me before, but right now it seems like his dick is kind of out of commission and he's never interested in getting me off any other way. Plus, it feels so rude to ask him to go down on me when he's all embarrassed. It's like I'm trying to rub it in his face or something."
"Literally," jokes Cynthia. Vanessa giggles.
"Seriously, though," Vanessa says, cuddling up closer to Cynthia's body, "I'm so sexually frustrated. I've tried to masturbate, but I can never get myself to cum."
Cynthia feels Vanessa's hot breath on her chest as she speaks, and goosebumps spread across Cynthia's body. It dawns on her where Vanessa's heading.
"I feel like if I don't have an orgasm soon, I'm going to go insane," her best friend/nemesis says suggestively.
