As Jeff the dick sat in his after glow, he heard the door click.
“Jeff? You in here?” A voice said
Before Jeff could think of anything he heard his sister gasp
“A dick? And jizz?” She said and gently picked up Jeff
Jeff involuntarily quivered at her touch and spurred out more cum.
“Ah! It’s a alive!. Wait... Jeff?” She asked and Jeff quivered at his name
“Jeff how did this happen? Does anyone else know?” She asked and Jeff rolled side to side.
“This is weird. Wait, you came when your sister touched you you pervert! And you’re getting hard again. I know what to do”. She left Jeff on the bed and left the room when she returned she was holding a chastity cage
“A pervert like you doesn’t deserve pleasure. Guess I have to get you small again so you’ll fit”. At this she put Jeff in her mouth and started sucking. She licked him up and down, almost swallowing him before Jeff spasmed and came straight down her throat
“Gross, in the cage you go” Jeff’s sister said as she adjusted the chastity cage to the disembodied cock.
She left Jeff on her bed as he was desperate to orgasm again but now being unable to even jerk off
