Pull out and have her swallow it

Assuming you've read her right, you're pretty sure Zoe is the type of girl that will do a little ass-to-mouth and you're still a little torn about having her stop that blowjob earlier. As you start to move to your feet, letting your cock slip from her ass, you decide to see if she'll, indeed, go for it. "I want to feel your lips around me one more time, Zoe. Suck me off. Make me cum with your mouth." you say, not quite asking, but not quite demanding either.

Zoe doesn't even bat an eye, hopping off the bed and dropping to her knees in front of you. Grabbing hold of the base of your cock, she begins jerking your cock, fast enough to keep you near the brink, but not so fast as to push you over it. Staring at your cock head she starts back up with her dirty talk. "Mmmm, you want me to blow you some more David? You want me to suck your big, hard cock until you cum in my mouth?"

"Oh fuck yes! You know you want it too Zoe! Now stop fucking with me and show me what a good little cock sucker you are!" you reply, knowing full well that she's going to do it. Without missing a beat, she does just what you demanded; opening wide and slipping your dick back into her mouth while continuing to stroke your shaft, sending shivers down your spine.

"Oh yeah stud, I can tell your close." she says, keeping your cock head pointed at her mouth while she picks up the pace of her stroking. "You're so right! I can't wait to taste you! I want to swallow every last drop of your hot spunk! Cum for me, David! Cum for me!" With that, she takes you back into her mouth and begins deep throating you for the second time today.

You were already close before, so it takes only a few moments of Zoe taking you down her throat for you to feel your balls tightening, signaling your eminent release. "Oh fuck Zoe, here it is!" you warn her.

With that warning, she takes you out of her mouth, leaving it open wide while sticking out her tongue, and begins rapidly stroking your cock, aiming it straight at her face. In mere seconds and with a loud groan, you release the first blast of your cum, splashing your load onto her tongue and hitting her chin. She continues working your shaft like a woman possessed, laughing out loud in glee, as you ejaculate into her mouth. She continues on like that, giggling and squealing like a school girl until she milks the last of your cum from your balls and deposits it on her tongue, then looks up at you and shows you your load in her mouth before closing it and swallowing down.

When she finally releases your member, you flop down onto the bed, exhausted, and try to catch your breath. Your cock feels beaten and bruised, and on any other day you'd probably call it a night, satisfied that you'd managed to fuck four girls in one day. Today is not that day though; knowing that you're two girls away from accomplishing what no other man has accomplished before, your mind starts thinking about the last of the friends you have yet to fuck. As your mind wanders to thoughts of other women, the one that you're in the room with gets to her feet and walks towards a mirror hanging on the wall. She apparently sees a drop of cum on her chin, because she wipes it off with her finger before sticking that in her mouth to suck it clean.

Glancing over her shoulder at you after she finishes, she laughs at your collapsed form. "Awww, did I wear someone out?" she asks you, teasing you with the tone in her voice. "Well, I've got to hand it to you, I didn't think you'd have that much left in you after being with those other three today, but it looks like we may have found your limit, hunh?"

Not even close to willing to admit defeat, you climb to your feet, standing in front of her in all your naked glory, and point down to your member. Though not fully erect, you're far from completely flaccid and you know you've got at least one more round in you. "Oh, I don't know if I'd say that yet Zoe. I'm not one to give up and there's still two more of your friends that I haven't fucked yet. Someone mentioned to me a record that needs to be broken tonight."

She smiles at your bravado as she begins gathering her bikini and slipping it back on. It doesn't take her long to put her suit back on, and she doesn't bother waiting for you when she's finished, instead making her way towards the door. Pulling it open, she turns back to you before leaving, wishing you good luck with the rest of your night and blowing you a kiss before leaving the room and closing the door behind her.

You can't help but smile at her casual attitude and are relieved she didn't want to stick around and talk or cuddle for a bit. As you start to gather your own clothes, you see there's an attached bathroom to this room and decide to take advantage of it and clean yourself up. Moving to the sink, you let the water warm up then lather up your dick, balls, and pubic region with soap and water, cleaning off the remains of bodily fluids that coated you. A nearby hand towel dries off your nether regions and you quickly dress yourself in your clothes before leaving the room.
