Cynthia tells Mark about Vanessa's visit

Before Mark gets home that night, Cynthia opens the iCock app to apply the Cuck setting only to find that the app is temporarily down for maintenance.
Dammit, she thinks to herself, Well, I'm not going to hide what Van and I did from him, so I guess I'll just have to tell him without using the app and hope for the best. She wonders how he'll react without the app influencing him.

Mark arrives home right on time, greeting her infuriatingly casually considering he'd cheated on her earlier that day.
"There's something I need to tell you about," she informs him, her tone serious, "Vanessa came over today." Cynthia thinks she sees a flicker of panic cross Mark's face before he responds, his tone as nonchalant as he can make it.
"Oh? How's she doing? " he asks.
"Well, you know how at the party, she begged me to make her cum because the guy she's been sleeping with couldn't get her off?" she says, "They're still having issues, and today she showed up with a strap-on and asked me to wear it."
"What?" Mark is clearly surprised.
"Yeah... and since you didn't have a problem last time, and since she seemed so ****..."
"You actually did it?" he asks incredulously. Cynthia nods.
"Please don't be mad," she says quickly.
"I'm not mad," he assures her, "I'm just surprised. It's hard to imagine you wearing a strap-on."
"Do you want to see it?" she asks, "Vanessa left it here. She told me to keep it."
"Sure," he says, sounding a little more eager than he probably intended. Glancing at his crotch, she notices that he's hard.

Cynthia goes into the bedroom and puts on the strap-on, wearing it with a t-shirt the way she had with Vanessa.
"Okay, come on in," she calls out.
Mark's eyes widen as he enters the room and takes in the sight of Cynthia wearing the dildo. He sits down on the bed, and Cynthia sits beside him.
"It's weird, right? At first, I didn't know what to do with it. I was so nervous, I couldn't bring myself to fuck her, so I just lay beside her and fingered her," she recounts, placing her hand on Mark's bulge, "I got into it, way more than I did last time... I even sucked her nipples. I got so carried away that I ended up getting her off with my hands before I even stuck it in her. It reminded me of you, the way you've been lately... cumming just as things are beginning." Mark blushes at the mention of his poor performance and begins to mumble an apology, but Cynthia shushes him.
"It's okay, I know you don't mean to," she says, "Anyway, with Vanessa, it wasn't a problem. She could go again, and she still wanted me to fuck her, so that's what I did." She moves so that she's facing Mark on the bed, the strap-on grinding against his bulge.
"If you think the idea of me and Vanessa making out in college is hot, you would've loved this. She wanted it so badly. She begged as I fucked her, telling me how her boyfriend's cock couldn't please her like I could," she watches Mark's face as he struggles not to react to the insult, "To be honest, I think I needed to get off almost as much as she did. I was fucking her like I'd just gotten out of prison."

She grinds harder against him, and Mark lets out a small grunt, trying to act macho through this. Cynthia squeezes his hard cock through the fabric of his pants.
"You think that's hot, huh?" she says, "Maybe I should get the lube, and I can make you cum the same way I did Vanessa."
