She needs a signature

Brian pulls out of the comatose girl, as you ease her off, leaving her sprawled on the couch, seed oozing from her holes. You cover her with a rug and stroke her hair before taking her pulse.

"She's Ok, she just fainted," you smile. The two of you dress, chuckling softly, as you wait for Serena to return to her senses. It took ten minutes, but she finally lifts a woozy face and looks about her in confusion.

"Did I do good Daddy? Was I a good slut...?" she asked, her voice fuzzy and uncertain. "I did do good, right?"

"You did very good sweetheart," you reassure her, bending down to kiss her forehead. "You ok?"

"I never...never did anything...like that..." she murmured. "I thought I was going to die I felt so...so good."

"You were a champ, Serena," you laugh, rubbing her head. "Coach Watts says you need me to sign something?"

"Yes...yes...could you...sign, or make a mark...near my pussy...please sir...." she pauses, looking up at you with timid but excited eyes. "Please Daddy, please sign me."

She pulls herself up on the couch, sitting so that she could face the two of you. She looked at Brian for a moment as though seeking reassurance before turning to you and spreading her legs wide. Reaching down, she opened her folds, biting her lip at her own brazenness. "Its for a bet, right? So if you don't sign, I won't be able to prove it to the other girls..."

"My pleasure," you chuckle, uncapping a permanent marker and writing a cursive "D" beside the E-6 that was already there.

"D" for Daddy," you say, giving her a gentle kiss on the lips, then tapping her nose with one finger. "That's quite the fantasy you have there sweetheart."

"I... err yeah" Serena laughed nervously, flushing red. "Um, please don't tell my parents! I think I would actually die if they found out..."

"The chances of me telling your parents that I've been fucking their daughter while she works out her Electra fantasies is zero," you laugh. "On the other hand, if you want to pay another visit and work on them again, I'd be more than happy."

Serena blushed and giggled in embarrassment, hiding her face for a moment. She looked utterly cute and adorable, and from the lingering gaze she gives you, you have no doubt that she'll be back again to explore her Daddy fantasies. Your tired cock gives a twitch at the thought of exploring her young body again.

"I better get going," she says shyly, looking at both of you under her eyelashes as she stands on legs that seem to tremble slightly. "That is....I mean...if that's ok...I mean...with you..." she adds uncertainly, blushing again.
