Yokoshima sensei approached a chair-bound and handcuffed Takatoshi. His cock was hanging out semi-limp, recovering from a footjob courtesy of his teacher's soft feet. ''Well, we definitely know that you love feet now. How about something more unconvetional?'' She said with a grin, as she raised the stump of her below elbow amputated right arm. She slid the scarred tip of her stump along his cock causing him to flinch in ecstacy. Her grin growing wider she grabbed his once again erect member in the crease of her elbow. ''I'll treat you first, but you you'll have to clean my stumpy up afterwards.''
