Let him fuck you
From Create Your Own Story
"How will we do that master?" He says. "Fuck me then Threepio, In my ass." you say. "Yes, Master" He says. Threepio picks you up and puts you on your tooltable after clearing off the tools. He proceeds to strip you of your underwear. He then starts to enter you. Pain and pleasure mixed into one courses through you. You start playing with your penis. You scream in pain. "Should I stop, master?" Says Threepio concerned. "No, Keep going." You say gasping. Threepio keeps going. Over time the pain subsides to pleasure, Intense pleasure. You moan his name. "Threepio! Oh yes! Fuck me Threepio!" Threepio suddenly shoots a warm liquid into your ass, deep inside. He then pulls out of you. You remember about a anal toy you saw in the trash just outside.
