Autofellation

"You shouldn't use your hands to jerk off." Dr. Valentine said stopping John from normal masturbation. "You should rather take advantage of your posture and do some autofellation."

"Autofell-what?" John asked not knowing the word.

"Autofellation." The therapist said stressing every syllable. "I'll show you, so stay relaxed and let me guide you." She stood behind John, giving him a good view from below her breasts. "First you take your legs and pull them further back with your hips rising some more." She pulled on John's legs. "Then you raise your head and curve your back." She pushed his head up after John was holding his legs, causing his face to nearly touch his erection. "And finally you wrap your lips around your cock and suck it off until you cum."
