Pump that cock

"Who am I to argue with a medical authority?" I replied, moving a hand down to the shaft of my penis.

I started moving my hand up and down the length, letting out a sigh at finally being able to deal with my insistent erection. Sarah made appreciative noises in my ear and began kissing the back of my neck. Her hands curled around my waist and down the front of my bare thighs. I continued rubbing my cock as I clasped my other hand to hers. The initial shock of embarrassment combined with the horniness from jerking off in a strange environment made the rising feeling of an impending orgasm build quickly. I guided her hand to the spot right between my legs. Understanding instantly what I wanted, she ghosted her fingers back and forth; I was unable to hold back from orgasming right then and there. Sarah made cooing noises and said:

"My, my. The treatment seems to have been highly effective. Though a relapse is entirely possible. Here. Let me help you clean that up."

She stepped away from me and pulled a towel out from the cabinet in the corner of the room, handing it to me before leaning against the counter, watching me as I carefully cleaned semen off of my still erect cock.

"I feel a bit bad that you're the only one disrobed. Would you prefer to have some company?" Sarah asked.
