Mexicanas are ideal for anal and I have slept with many. I'd love to be with this couple and when he pulls out of her asshole, take his cock into my mouth so I can taste and smell her ass on it. Then, once he's cleaned up, suck his cum out of her asshole. I've eaten creampies (my own and other men's) from female assholes and I love how semen tastes when mixed with the female ass. Truth be told, I've sampled my own cum from a guy's ass and must admit I enjoyed that taste/smell too!
That is REAL. Nice. I would have kept my dick in her after cumming, to make sure my cum went nice and deep into her pussy, and to make sure it didn't leak out.
