You have Emma ask Isabella for a photo in return

While Isabella calms down from her pleasurable full-body orgasm she continues to stare at the photo of her good friend Emma's mouth stretched and filled with your cock. She's practically drooling.

She decides to take all five fingers of her right hand and shove them into her mouth, trying to mimic the feeling of having a huge cock penetrating her oral hole.

She can taste her pussy juice on her fingers and the image this conjures is surprising to her: she imagines that you have just pulled your cock out of Emma's pussy and that it's Emma's fresh pussy juices she can taste on you. Isabella has eaten pussy before during college, but never Emma's. She finds herself wondering what Emma tastes like. She's heard that you love eating Emma's cunt - maybe Emma is particularly delicious.

Isabella almost gags on her own fingers when Emma's next text comes through. Isabella thought that the games were over for the night but you had other ideas.

The text read: "Well... show us your tits now."

"Us" Isabella thinks, "Emma and John that means." Somehow she's gotten herself into this - this sexting with the two of you. It's not just two girls chatting about boys - somehow you got involved and you're a part of it. She got off on a dick pic that you basically sent. Is this cheating on Jacob, she wonders. Jacob is probably asleep in their bed by now - she's been in the bathroom masturbating and texting for so long.

Isabella has already cum a couple times, normally her pussy would have dried up by now, but she reaches down and feels how wet she is. She spreads her lips and looks down to see the wet, pink, fleshy opening of her cunt. There's no denying that there's a part of her, a soaking wet part of her, that wants to keep pushing things forward.

Isabella looks down at her breasts that are covered in a thin white t-shirt. Her nipples are poking through the soft fabric. She wants you to cum thinking about her and her big boobs (so much bigger than Emma's! - but texting a photo of her tits to you - even through Emma would be the recipient of the text seems like too much of a violation of her relationship with Jacob.
