Michael can’t find his Biology textbook anywhere, and he has an important exam coming up! He walks into his stepbrother’s room and asks if the little guy has seen his book, but the kid adamantly denies it. Michael senses there’s something fishy afoot, so he searches the bedroom until he discovers the book under his little brother’s pillow, open to the chapter on the male reproductive system! It can be hard for a little guy to learn what’s going on with his adolescent body. Michael offers to teach him a few things. He names each part of the kid’s cock as he touches it – from his massive head, to his long shaft, to his fuzzy balls. Then to provide an even more in depth understanding, Michael bends him over and teaches him about his prostate, teasing a big load from the boy before burying his seed deep in his gut.
