How would you feel ?

So I was making out with my bf in the car, he cummed, we proceeded to continue and we're getting ready for sex , so he was trying to get hard again ( forgot to mention it was night time ) he gets on his phone (trying to be slick ..turns his phone away ) while I'm taking off the remaining of my clothes and from the reflection of the window I see him go on Instagram looking at a picture of another women who's wearing a red bra while he's jacking off to it . Like WTF ?? You don't see me masturbing to a picture of Dylan O Brien or some other person while you are next to me !? 🙄
