Your relationship with Allison gets closer

Once Allison's gone, Fiona claps you on the back with a laugh. "She's a keeper for sure! Let me know once she starts asking for another dicking and I'll help you out." Making it sound like she's doing you a favor, Fiona strolls out, leaving you with a room reeking of sex and a lot to think about.

By the time you're ready to go to bed for the night, you still haven't sorted out how you feel about everything, and you aren't sure what you'll say next time you see Allison. You want to sleep on it, but it isn't easy nodding off...

Your bed is soaked in places with your girlfriend's juices, and the scent of Fiona's cum lingers in the air - perhaps in part due to the condom left behind in your trash. The mingling scents make you recall the intense scene of Allison getting fucked, and your cock throbs to life as you imagine pounding Allison's pussy the way Fiona did.

Unable to sleep, you grab some tissues and masturbate furiously to the mental image of Allison thrashing in delight as a huge cock nails her. Your imagination slips back and forth between the fantasy of you fucking Allison and the memory of your sister doing it, and before long, you cum explosively...

When you run into Allison at school the next day, you're nervous enough to consider running away, but her friendly smile helps put you at ease. The two of you chat normally, not bringing up the previous night while still in public. Oddly enough, you don't feel anywhere near as awkward around her as you'd have expected after the previous night.

And to your surprise, Allison seems more willing to show of your relationship in public though, practically gluing herself to your side for half the day in a way that has your male classmates staring enviously.

As classes end, Allison pulls you along into an empty room and ushers you into a chair. "Allison...?" Not sure what she's up to, hesitantly sit down, only for your girlfriend to drop to her knees in front of you. Reaching up, she starts fiddling with your pants seductively, showing signs of removing them.

You swallow back your questions...is Allison really planning on blowing you in an empty classroom? The place is a bit out of the way, and there's no reason in particular for anyone to come in...but there's no 100% guarantee that no one will either.

"I wanted to thank you for yesterday...it must have taken a lot of courage to commit to that." She smirks teasingly. "To letting your friend fuck me with his huuuge cock...most guys would be too insecure to explore their cuckold fetish." As she speaks, she gradually tugs your pants and underwear down, leaving your cock exposed. The mix of talking about last night - and the seemingly impending blowjob - has you already partially erect by the time your cock is free.

"Since you've been so eager to experiment....I thought I'd try being a little adventurous too..." Leaning forwards, Allison kisses the tip of your cock playfully, then gives it a few tentative licks. You muffle a gasp of pleasure, going from semi to rock hard in moments. The thought that someone could come in worries you, but the added tension in the air adds an extra spice to everything.

Allison laughs softly, giving your cock a few more experimental licks. You bite your lip to keep from making any noise, but still let out a muffled groan as your girlfriend opens her mouth wide and starts slowly but surely sliding her lips down the shaft of your cock.

Your body tenses in raw pleasure as Allison gradually manages to **** the entire length of your cock past her lips, the tip even reaching her throat.

She's never done this to you before, and the relative ease with which she deepthroats your cock surprises you. Even if you're tiny compared to Fiona, taking six inches of cock without gagging can't be all that easy.

You groan again as Allison begins bobbing her head up and down, slowly at first, but with increasing speed. Her eyes are fixed on yours, making the blowjob all the more intimate.

In just a couple minutes, you feel yourself reaching your limit, and you let out a hurried warning. "C-cumming!"

Allison shows no signs off backing off as you buck your hips and begin to cum with what feels like the **** of a firehose.

Allison seems to gag briefly, but recovers quickly, gulping down your load as it comes.

You can't hold back a gasp as she sucks the leftover cum from your urethra, then releases your cock with a pop.

You sag back in your chair, feeling drained in more ways than one. Allison wipes her mouth, then grins up at you.

"Well?"

After catching your breath a little, you manage a smile of your own. "... That was... Amazing."

Allison's grin widens. "Thanks, I thought I'd put some extra effort in. Just because your hung mystery friend owns my pussy now doesn't mean we can't enjoy yourselves together. Actually, your size is a lot better for sucking I bet... Easy to fit it all in."

Allison stands up and you have a moment to decide if you'll let the encounter end like this or try to reciprocate somehow.
