Today's lesson is female anatomy so Sailor starts by stripping off her top and explaining what the nipple and areola is. Sometimes breasts and nipples are sensitive and sometimes the areolas grow hair, it's all very natural. She lets him touch her breasts as she mentions part two of the lesson. Has her little brother Kyle heard of a blow job? It's when a girl puts a boys penis in her mouth and plays with it. Sailor sucks and licks his cock showing him a very thorough example of a blow job. She is a really helpful sister and breaks down all of the proper ways to suck a dick and how you can tell what kind of girl she is by if she swallows the cum or not. No surprise here but big sister sailor swallows and she is a very dirty girl.
