You make Bella choke on your cock

Bella: I can go far enough

Aiden: Prove it

Bella is done with making your cock wet, and starts sucking it like her life depends on it

Aiden; that's it whore keep sucking

Bella: Why does it feel so good when he degrades me

Aiden: but I know you can go deeper

Bella tries, but fails to go deeper

Aiden: are you listening whore, I said go deeper

Bella: I'm trying

Aiden: I'm disappointed in you Bella, I guess I need to show you how to properly suck my cock

You grab both of her ponytails and force her down your entire cock

Bella: MY THROAT

Aiden: stay like that

You let go of her and just as you ordered, Bella keeps her mouth all the way down your cock

Bella: I CAN FEEL HIS COCK ALL THE WAY DOWN MY THROAT

Aiden: That's it keep it all the way down

5 minutes later

Aiden: I think your throat is used to my size now, start sucking, and your not allowed to pull my cock from your mouth

Aiden: is that clear

Bella nods to you

Aiden: good, so keep sucking

Aiden: That's it, I knew you could do it

Bella: I'll show him that I can take it

Bella takes your entire cock down her throat, without help this time, and then winks at you

Aiden: goddamn, looks like you have mastered my cock

Bella: Yeah I have

Aiden: Then let's begin the next exercise

You take your cock out and start jerking it

Aiden: but I still have to do one thing before that

You cum all over Bella's face

Bella: OH GOD, SO MUCH

Aiden: That was nothing compared with what's coming next
