Surprising my sister with a blindfold and a big dick on her birthday

Surprising my brunette sister on her birthday, I blindfolded her and revealed a big cock. She eagerly sucked it, then bent over for a hardcore pounding, culminating in a messy cumshot on her boobs.

Rolled up to my sister's crib to celebrate her birthday, and she's all gussied up in a little black dress. I surprised her with a blindfold, and before she could even process what was happening, her boobs were out and I was stuffing them with my throbbing cock. She's a total vixen, taking it like a champ and even deepthroating me while blindfolded. But the real show starts when she bends over and I take her from behind. Her sweet little ass gets pounded hard and fast, and I can't hold back any longer. I unload all over her back, leaving her blindfolded and covered in my hot load. This is a classic birthday surprise that's sure to be remembered.
