Her sounds and moaning and the "oh yeah" are dick hardening, and she is an awesome stocking and heels model. You are lucky to get to blow loads into her often, and well probably for the rest of your life since you all are so "close" and you know you like banging each other.
It’s so hot going out with her to a friends place with everyone knowing she’s my sister but not knowing what’s going to happen at the end of the night!
love it, sexy as fuck. People make the oddest things taboo, if your sister is hot and loves to model her hose and fuck..and you get hard, its just natural. My sister is not hot however. LOL
