Cynthia waits for the day when she and Roussard will set up the tech

The night before Roussard is planned to come over, Cynthia sets the wheels in motion, complaining to Mark that she feels sick. He doesn't seem particularly concerned, and still tries to initiate sex with her, despite his arousal not even being significantly elevated by the app. It really pisses Cynthia off, and she goes to bed early and without eating, both to help sell the idea that she's sick and because she'd rather sleep than spend her evening with Mark. She wakes up hungry in the middle of the night. Mark still isn't in their bed. She treads softly out to the kitchen, at first assuming that Mark has fallen asleep on the couch, but as she approaches the kitchen-lounge area, she hears Mark's voice.
"Ooooh, fuck yeah, spread that pussy. You're so gorgeous." Cynthia tiptoes forward, and another voice, clearly being emitted from phone speakers, becomes audible.
"I'm so wet. Jerk that cock for me." It's Vanessa. As Cynthia moves silently closer, she sees Mark on the couch, engrossed in whatever's happening on his phone screen as he jerks his soft cock with rapid strokes. Clearly, he's horny enough that lacking an erection won't stop him from attempting to get off. Joke's on him, Cynthia thinks, smiling to herself, his cockblocks are still on. He's not going to be able to cum, no matter how hard he tries.

She carefully turns and tiptoes back to bed. She's still struggling to get back to sleep when, over half an hour later, Mark comes in and gets ready for bed. She pretends to be asleep as he settles in by her side and drifts off to sleep. As he snores beside her, Cynthia has an idea. You want to get off, huh? she thinks to herself, Oh well, I'm awake anyway... She picks up her phone from her nightstand and opens iCock. Her heart racing, she taps the cum button and quickly but carefully places her phone back on the nightstand. The listens as Mark lets out a moan which turns into a surprised grunt as he awakens to the feeling of his soft cock spewing cum into his flannel pajama pants.
"Fuck," he hisses to himself, sitting up and snatching back the duvet.
"Hhm?" Cynthia pretends as though he's just woken her up, "What's wrong?"
"Nothing," Mark says quickly, his voice rushed and breathy as he squeezes his still-oozing cock. Cynthia sits up, turning on her bedside lamp, and sees Mark getting up from the bed. There's a huge wet spot on the front of his pajama pants, even darkening the bottom of his shirt, and Cynthia notices that quite a lot of cum has gotten on the bed, too. He must have built up quite a load jerking off with Vanessa.
"What happened?" she asks in a disoriented, just-woken-up voice.
"Don't worry about it, it's nothing," he says as he awkwardly strips off his cum-soaked clothes. Globs of cum which weren't caught by the fabric linger on his thighs.
"Did you jerk off? Right beside me?" she asks. He shakes his head, looking embarrassed.
"I had a wet dream," he admits. Cynthia lets out a laugh.
"Really?" she asks incredulously. He sighs.
"Yep."
"Huh. Are you good to clean everything up?" she asks, "I think I'm gonna sleep on the couch."
"Yeah, I'll clean up," he tells her as she rises from the bed, grabbing her pillow and her phone. She smiles to herself as she picks up a blanket from the linen closet and settles down on the bed.
