Post blowjob relaxing

I sit there with my eyes closed, just enjoying the moment, then I realise Sara has sat down next to me on the love seat and is casually looking at her Instagram page. I look at her for a little bit, thinking wov, she just sucked my cock and swallowed my cum and now she is sitting here next to me like nothing just happened. Am not sure I like this for some reason, even though it should be every man's dream to get a girl to blow them and not even want to cuddle afterwards.

"So, that was nice..." I say and look at her.

"Glad you enjoyed it." Sara replies without looking up from her phone.

"Well, wow, it was very nice." I continue trying to make a bit more conversation.

"Matt, it was just a blowjob, you helped me out with something and seem nice so I wanted to give you a treat." Sara answers, again without looking up from her phone.

Am not sure what to do or say, so I decide to try to act cool and pretend like nothing, so I just say:

"Okay, cool."

Then take out my phone and play with it as well. We sit for a while in silence, then Sara's phone beeps. She looks at the message and says:

"Matt, I got to go inside for a while, you can wait here if you want to."

More a statement than a question, so I nod to show that I will do that. I try to give her a kiss as she gets up, but she turns her head away, avoiding the kiss, instead she reaches for a notepad which she hands to me while saying:

"Matt, I want you to read something I've written, I'd be curious for your thoughts."

I smile and look down at the notepad, but am not feeling very enthusiastic inside, but as she climbs out of the tree house I open it and look at the first page, where it says, in big decorative letters:

"Sara's Story"
