Dr. FrankenFuck's Fist Lab

Dr. FrankenFuck's assistant, Scotty Taylor, is enjoying eating out the asshole of his master's monter creation (Pierce Paris) in the laboratory but when the Doctor (Hugh Hunter) enters, he's upset to find his assistant disobeying his orders. As punishment, the Doctor bends Scotty over the table next to the creature and decides to give both of them the same treatment. The Doctor takes a massive rubber dong and drives it into Scotty's hole but when he realizes he's not giving the creature the attention he deserves, he grabs another massive dildo and slides it into the creature's tight ass. The Doctor doesn't discriminate and goes back and forth between the two hunks to stretch their asses and make room for his fists. When the Doctor can see that both hungry holes are ready for more, he dips his gloved hands into his vat of grease and starts in on fisting the monster, then Scotty. The studs moan out as the Doctor fucks each of them with his fists at the same time. The guys jack their big cocks as the Doctor keeps up his relentless destruction of their assholes. The treatment is working and the monster is the first to let loose a gusher of cum. Scotty can no longer hold back and as the Doctor slides his hand in his ass one last time, Scotty sprays his own chest with ropes of cream. The Doctor is satisfied with this round of treatment and leaves Scotty alone with the monster to clean up the mess.
