“Say ‘bye bye’ cutie. This is the last time you’ll see him not spilling out of your tight little ass~” the pred would say while you watch your boyfriends fingers get sucked into his monstrous cock

Or the one I see the most often of like a magic doll that you fuck with ur normal sized dick and then the human that the doll is made to reflect gets fucked by a proportionally much larger invisible dick. LOVE that.
