She switches places with you

Your mind reels. You weren't exactly sure why you did that, and now the salty, thick taste of cum coats your throat. Sophia is smiling at your clear confusion. "Don't worry, baby," she coos. "We're just having fun, right? Don't you feel good?" You have to agree that this is the best you've felt as far as you can remember. "Yeah... I do feel good." She smirks at you, before looking up with pleading eyes. "Well, you've gotten to cum now, don't you think..."

"Uh, oh of course!" You start to reach for your phone. "Want me to-"

"No, baby. I think we've had enough play with that for now. I just want your tongue." She punctuates her sentence with a small moan. Despite having just cum, your dick twitches. "Of course, Sophia. Do you want to go to your bedroom or...?"

Sophia stands up and your breath is caught as you take in your friend's tight form in her lingerie. "No need. Why don't we just swap?" She points down at the ground where she was just kneeling. Something about the way she points rubs you the wrong way, but you slip off the couch to kneel on the floor. As soon as you do, a now-familiar warm feeling washes lightly over you. It was nice listening to Sophia. She makes a show of slowly peeling her panties off, revealing her beautiful pussy, and sits down on the cushion, swinging her foot over your head so you sit between her legs. She motions gently with her finger and you lean forward, starting with some soft kisses and tentative licks. She reacts immediately, head falling back as she moans. You revel in her pleasure, and double your efforts, starting to lick firmly and rhythmically.

"Unh, fuck..." she mumbles under her breath. You barely register her holding your phone again before turning to focus on her dripping cunt.
