You empty your balls right down Isabella's throat

Isabella's eyes light up at the mention of you cumming.

Isabella wasn't sure if this blow job would be cut short at any moment so you could start fucking her, but as much as she wanted to be filled by you, she also wanted you to cum.

Isabella's views of blowjobs probably differ than most women - she felt like if the guy doesn't cum it like doesn't even count. All that work for nothing, more or less.

Similarly Isabella never understood how spitting could be an option... like how could a girl who spits out cum really expect a guy to eat her out. She likes a guy to spend like an hour with his face swimming in her pussy cum - taking a dude's load in her mouth and swallowing it seems like a much easier deal. It's not like all guys' cum tastes great - but some of it really did. It wasn't unheard of Isabella to have a craving - the same way she'd have a hankering for pizza or ice cream - for jizz.

I'm such a slut, Isabella, thinks as she finds herself salivating at the anticipation of your cum. "I'm going to fund out what John tastes like!" she thinks as she realizes it's been far too long since she tasted a new guy.

It's less surprising to Isabella that you're about to explode into her mouth than she was sexting dirty pictures back and forth with Emma. Isabella never really liked you - so she didn't expect to be in this position with you. But she's always known she was on the slutty side, so it's not like incomprehensible that she'd cheat on Jacob or even that she'd suck off a guy while his girlfriend watches.

Back in college she kissed a guy while his girlfriend watched. The girlfriend got cold feet though, so the threesome didn't happen. But Isabella was ready for it. A few weeks later she gave the guy a pity handjob, as if she could cure the blue balls he got retroactively. After he came in her hand she tasted his cum - she really always has been a cumslut.

Isabella hears you loudly moan out right before the first blast of cum splashes against the back of her mouth. She tightens her lips around your cock as she continues to stroke you with her hand. Isabella has to swallow the cum while you're still shooting more into her mouth. Maybe seven blasts of cream later the torrent stops, she swallows again, and Isabella loosens the hold her mouth has on your cock. She can breath again and tries to suck just a couple more drops out of you before she fully relaxes and looks up at your pleasured face with pride.

Not a drop has been spilled. Your cum has been carefully relocated from your balls right into Isabella's stomach through the process of one terrific blow job.
