Giving Tracy a treat Mia craves

You and Tracy spend nearly an hour fucking in every which position in front of Mia until finally you have Tracy back on her knees in front of Mia's cage. Mia is almost as much of a hot sweaty mess as Tracy is just from watching. She's like a cock addict suffering from withdrawal symptoms.

Whilst you jerk your cock preparing to spray your cum on Tracy's face, Mia presses her face against the cage with her mouth agape, desperately hoping you'll miss and a little bit of cum will reach her mouth instead of her sister's face. Of course, you've had more than enough practice and so when you do release your load, it all perfectly paints Tracy's face with strands of glistening white cream.

As you look down and see your girlfriend's face covered in your seed, you look to the side to see her sister with a face of despair as she realises she won't be receiving this tasty treat. In this moment you feel pity for her and decide to show mercy.

"Slut, why don't you let your sister lick the cum from your face. It's the least we can do for her after she had to watch all that."

Tracy looks a little disappointed but eventually does as you tell her and brings her face close to the cage. Mia being the cum hungry slut that she is, sticks her tongue through the gaps in the cage and eagerly licks up every drop of cum from her sisters face.

With your first fuck of the evening through, you lead Tracy upstairs to the bedroom and leave Mia to her own devices. She's suffered enough tonight.
