Why take even a small chance? You want food, not to be food. So sneak up on the feeding brunette. She is too busy eating the blond to notice your approach and as the blond's rack is being engulfed, she is leaving her own feet open for your attack, which you swiftly do.

Each hand grabs a foot and the pair is quickly crammed into your maw. Feet can have good flavor, but you know in advance she was going to kick like this, and so you have to have a good hold on her. Well, there is plenty more that will delight your tastebuds.
You have to say you are a bit impressed. Despite all the effort she is putting into getting out of you, she is still making good progress on the blond, who seems resigned now to being lunch. Maybe you were wise not to risk a direct confrontation.
But her efforts to get free are not working. In fact you are using them to drive her deeper into you. You dodge her downkicks and then get your throat on top of her upkicks. Each kick pulls her scrumcious legs another inch towards your belly.
For a moment she stops you by locking her knees, but you know the way around that. Just arch your back and the legs bend, and a quick swallow forces them to keep bending.

You pause at her hole. This will be the poor girl's last time and you want to make sure it is a good one. Only fair when you think of how happy the food is making you. Besides, a lass tastes a lot better just after she has had an orgasm, and the better she likes it, the better you will like her.
The brunette is clearly no stranger to sex with other ladies. She welcomes your tongue eagerly, and your probings would likely cause her to set a record for loudest come if the last of the blond wasn't muffling her.
She is too exhausted to fight any more, but you slip in her hands in front of her so she can continue to pleasure herself. Then in goes her shapely rump and extended belly, still filling with the unlucky blond. Her massive mammalares take a little work, and it's your good deed of the day to give them a good licking on the way down.
Once her shoulders are out of the way, you find she is done with the blond, and she cuts in with pleas to let her go. Unlike your earlier victims, she tries to insist you and she can be great friends and she can do you a lot of favors if you don't finish gobbling her. With your mouth full of her lovely throat, you really can't answer. Easier to just finish eating and then see if she can convince you not to digest her.

Her easing into your stomach sets off a wave of pleasure that makes you at least consider the idea of releasing her so you can eat her again. But you realize something more immediate has to be dealt with 1st.
There is now another woman behind your back, and you have left yourself as vulnerable as the brunette was.
