Of course you are

Without even realising it, you grab a handful of her hair and pull it back out of desire. Your other hand continues to drive her down by her ass but she suddenly fights against you as she shudders hard.

"FUCK! YES! Pull my hair!" She slurs as words seem difficult for her while she comes.

It's too hot for you and you simply start to thrust up against her even while she's riding her orgasm.

"WAIT! AHHH" she screams even louder, your thrusts driving her crazy. Her sensitivity seemly through the roof, but it can't stop you. It won't stop you.

The parasite starts to creep into your mind. The desire to mate. To fill her up. With a growl and a swift moment you roll her over. Your new muscles flexing without issue and she's suddenly pinned under you.

Her eyes come back into focus and look up at you with a mixture of fear and arousal. "Phew.. that was inTENNNSEEE" she goes from gasping to shouting again as you start to drive your thick cock back into her.

Nails dig into the skin of your forearms as Olive winces with the thrusts, squirming as her pussy absolutely soaks your cock. You can hear your heartbeat in your ears as your cock swells ready to come.

A deep growling reverberates in your chest as you get closer. She's yours. You're going to claim her and flood her womb with your cum. Do it.

Looking deep into Olive's eyes, you see tears roll down her cheeks just as the flood gates open.
