Young girlfriend masters deepthroating skills with help from step sister

When the young guy's girlfriend first came over, he was eager to show off his skills. Unfortunately, she wasn't impressed with his junk and decided it was a bit too small for her taste. The guy, being the resourceful lad that he is, enlisted his step sister to give his girl some professional deepthroating lessons. The step sister, a voluptuous Latina with a big ass and perky tits, was more than happy to help out. She took the young girl's head in her hands and showed her how it's done, teaching her the finer points of deepthroating. The young girl, initially hesitant, soon got the hang of it and was able to impress her boyfriend with her newfound skills. The step sister, satisfied with her tutelage, left the two lovebirds alone to enjoy their newfound passion. The girl, now fully satisfied with her boyfriend's package, vowed never to complain about size again.
