Latina girlfriend enjoys deepthroating and anal sex with neighbor

My Latina girlfriend has been hanging out a lot with her neighbor lately. Apparently, he's got a big cock and she can't resist the urge to deepthroat it every time they're alone. She's such a slut for it, and the taste of his pre-cum just makes her hornier. Recently, she decided to invite him over when I wasn't home. I walked in on them and was shocked to see her getting her tight ass pounded by his big cock. It turns out, she's into anal sex too. I couldn't help but get turned on and joined in. We all had a wild time together.
