Imagine you are the guy in the charis stroking your little dick while your girl humiliates you. She can't understand why you want her to fuck another guy. She just knows he is so much better than you and she can't help but to cum on his dick over and over again.
Give me a edge while you picture the guy touching what is yours and making her grind on his dick. It must feel so good inside that wet tight pussy. You wouldn't know though because you just have to stroke and watch.
Once you have edged let it go limp and continue.
