Keeps up the act.

Slowly, she reaches out for your cock, and flinches away realistically when it twitches in anticipation. "Just grab it! It's not gonna bite!" Charlie snorts, trying to hold back her laughter.

"Shut up!" Selas snaps, a blush coming over her cheeks. "It's my first time seeing one okay! Geez..." Your face is blank and neutral during that quick exchange before scattered electricity makes it twitch. Your eyes close and a small moan comes out of you as you feel Selas' fingers start to slowly slide along your cock, applying different pressure with every stroke. "Wow... Its so... hard, but kind of spongy too. Does, does it feel good?" she whispers, looking up at you.

She knows it does. But unlike all the other times, she now has an audience, and you can feel in your mind what she wants your answer to be. "Yeah. Yeah, it feels great," you groan, swallowing loudly from her handjob. That groan turns into a silent wince as, hidden from Charlie's view, Selas' thumbnail digs into your cock. Seems like she wants you to play it up more. Clearing your throat softly, you groan again. "It feels so much better than when Charlie used her mouth."

The annoyed tongue-click and scoff off to the side, along with the immediate removal of pain, tells you that that was the correct response. Selas giggles, and brimming with confidence, takes your cockhead into her mouth. You groan louder this time, so much more than with Charlie, as she performs a perfect recreation of an eager if inexperienced blowjob. Your hand falls on her head and your own rolls back. Exhaling through her nose, Selas takes you in a hair too deep and pretends to gag. She pops off your cock, sputtering loudly. Your knees give out and you fall backwards into your sofa, panting heavily.

Wiping spit and pre-cum off her chin, Selas looks from you to Charlie. "How'm my doing, coach?"

Charlie narrows her eyes and replies flatly, as if brushing her off. "Not bad... for your first time. But you should be asking him." She squints at you with judgemental eyes. "So how does it feel? To have your cousin blow you?" Selas gives you the side eye as well.

Boxed in from either side, you disguise your defeated sigh as a tired exhale. "Really, really good," you cough, trying not to meet Charlie's gaze. "Great, great teacher."

She raises an eyebrow at that. "Right... and the fact that she's your cousin isn't doing anything for you?"

You would answer, but all that comes out is another pathetic groan as you feel Selas' cheeks squeeze around your shaft and her fingers jiggle your balls. "Fuck, I don't know, maybe... ah fuck..." Charlie just shakes her head and rolls her eyes at the pair of you, watching with an aloof interest at this borderline incestuous scene. Before long, you feel your orgasm start climbing up again. Grabbing onto Selas' head, you moan out your release loudly.

With believable panic, Selas starts to mock freak out, looking to Charlie for help, while you fill her mouth up with your cum. Surprisingly, you don't cum very long this time, but her mouth is still filled to the brim when you finally let go. Charlie is unfazed when Selas turns to her, with her cheeks bulging out. "Spit or swallow, Sara. Those are your choices right now."
