Daddy heads into his boy's bedroom and finds studying some biology homework. Dave doesn't think the penis diagram is very realistic, and Josh a better point of reference to work from: his own daddy dick! After Dave whips his uncut cock out, Josh accepts the offer of a hands on inspection and grabs hold of the growing boner. Josh sucks and slurps on that stiff daddy dick, making sure to inspect every inch of it with his tongue. They move to the bed, and Josh continues to blow his daddy before pulling out his own hard twink cock for Dave to suck in return.

Josh then bends over on the edge of the bed and Dave rims the boy, getting that twink hole nice and wet and ready to be penetrated. Dave slides his bareback dick inside and pounds Josh from behind, then gets the boy to ride him for a while before laying Josh on his back for a missionary drilling. As he takes that daddy dick, Josh strokes his own cock and shoots his load all up himself. Daddy Dave pulls out and blasts his load over the boy too, proving that his dick is much better to learn from than a basic diagram.
