Helping my little sister with her first anal experience

My sister's boyfriend Tyrone is a huge dick and HAS a huge dick. He wants anal. She is freaked the fuck out!!! What will she do? She doesn't want her gravy train to end with this sugar daddy mothafucka! Well, she comes to me and I can't believe it. I tell her that I will help. I grab my coconut oil and talk her into letting me finger her tight asshole. It turns me on so fucking MUCH!!! I can't help getting hard while her tiny feet graze against my throbbing cock. She gets turned on and lets me break her ass in for Tyrone. I LOVE FUCKING MY LITTLE SISTER AND HER TIGHT BUTTHOLE!!!! OMFG, I give her the biggest anal creampie EVER!!!!
