Jamal's erection began to pulse and swell as his mother's mass was relocated into it. Before he could process what he had done, his cock grew to 4 feet long, and a foot across, and his balls swelled up to the size of volleyballs, and beyond.
He doubled over, the sensation of his enormous dickhead suddenly grinding into Dechair's tits more than his mind could handle.
As he lay on the floor, panting and trying not to spray precum all over his room, he heard a terse, female voice.
"Child, you're all pent up! You need to relieve yourself! Didn't I raise you better than this?!"
Confused but subconsciously compelled to obey, Jamal began to rub himself slowly, sensations still very difficult to tolerate.
"Good, now do it faster."
He complied, his hand speeding up to satisfy this unseen director.
"Faster! Use both hands!"
Jamal placed each of his still-gloved hands onto his monsterous mother meat, the stroking finally overwhelming him. He blew his load all over Dechair's cushion-tits, making gobs of white goop rebound and fly all over the room.
