My Hot Horny Step-Cousin 4

As far back as you can remember, you have always been close with your step-cousin. Many nights over at your step-aunt's house, where you and she would stay up all night innocently play wrestling under the fort you built from her bed sheets. Well, you are now both grown (18+), and your cousin is now hot and horny. She still wants to wrestle under the covers of her bed sheets with you, but not in an innocent way. Do you stop her once her clothes start to come off, or do you succumb to your primal urges and feel how wet and tight her slit is for you? Fuck it. She is technically not even directly related to you.
