With gusto!

Melissa dives onto your cock. The first few strokes are clumsy and awkward. Teeth scrape over your glans, and she has some difficulty getting her lips around much more than the head of your cock. Beast isn't really helping her situation. The infection is growing in her, and you can smell a musky aroma coming from her pussy as she grows wet with arousal. The improved lubrication has its downside for her purpose though. Beast finds it easier to slide his long cock into her pussy.

Melissa moans around your cock as Beast drives deep into her. She shudders in an orgasm. With the infection firmly taking hold, Melissa pushes Beast into a sitting position behind her while holding you firmly by the hips and pulling you toward her. The infection has eliminated her gag reflex and Melissa eases your cock into her throat.

After a few moments of her licking at you balls, she pulls back and gasps for air. You can see Beast's cock swelling Melissa's stomach as he drives deeper into that she could ever imagine. She pulls beasts paws upward, urging him to caress her tits, then she flicks her tongue along the base of your helmet, holding you balls in her hand, one finger dips lower to tease your taint.

Melissa is quite skilled, and you feel your balls begin to burn.

"I'm almost there, bitch," you say, "Make me cum. Make Me Cum. MAKE ME CUM."

At the same time Beast is growling and whimpering. Melissa can't stop gyrating her hips around his swollen cock.

He growls, and you grunt. It's clear that your both about to cum, and at this point, you can't tell which one of you will claim her.

You roar as your cock begins to throb. Beast roars in time with you.
