He does

It looks like he's not used to someone returning the favour. His breathing gets more erratic as minutes pass, and often you feel him breathe heavily against your pussy lips, his tongue unmoving as he basks in the pleasure you give him with your mouth. His salty precum tastes like victory to you as he starts to hump your mouth, trying to get even more pleasure, his tongue work forgotten for now. You don't stop sucking and licking, making exaggerated slurping sounds and moans, doing your best to make him lose control.

As his breathing gets even more laboured, you hear him say "Miss...I'm....getting...close" You rejoice internally as you keep bobbing your head up and down his cock, readying yourself for his imminent orgasm. With a low growl of pleasure, he finally erupts in your mouth, a thick stream of cum fills you as he tenses. You do your best to keep sucking, trying to milk his dick to the last drop with your lips. When you think that you won't be able to keep everything in your mouth anymore, the flow finally stops as his dick starts to deflate and escape from your mouth. You see him look down at you, face flushed and eyes a bit clouded. You open your mouth a little, showing him the load that he deposited inside before closing it again and swallowing audibly, the bittersweet taste of his cum clinging to your tastebuds.

You then push yourself upright again, sitting back properly on the seat. As nice as it was to return the favour, you'd like to finish as well. You spread your legs and look at him, raising an eyebrow, silently challenging him to stop here. Without a word, he kneels in between your legs and resumes licking you.

Something changed in his attitude though, whereas he was confident and teasing earlier, he now feels completely different. Meeker and more Submissive you just realise. By making him cum first, you won this "sexfight" of yours and he's now paying the winner, you, her dues. You feel a rush of arousal fills you as you realise the new power balance at play here. This time, you're the one in charge, and it feels really good. "Good boy" You say as you pat his head, surprising yourself with how naturally it seems to come to you. He doesn't answer but you feel his tongue press harder against your clit, making you moan in pleasure.

As you finally cum hard on his tongue, holding his head against your pussy with both of your hands, the last thought in your mind before succumbing to pleasure is "I could definitely get used to this"
