I worked nights in a rehab center to pay for college. It wasn't all bad. My only duty was to clean up if someone got sick or shit the bed and play security if someone got out of line.

"Porn? You're watching porn?" a voice said over my shoulder as a hand grabbed my crotch. There was no denying it. She'd caught me one-handing it during my break in the darkened rec room. "Shit, that's not how you give head," she scoffed.

Sheri was an ex-groupie who didn't sleep much. She used to follow bands across the country and would brag about all the band members that she's fucked over the years. She was in her late fifties to early sixties, and barring a few sags and wrinkles, she still looked good for her age. Sheri was here rehabbing from surgery and was about to be discharged.

"Here, let me show you," she grinned while spitting her teeth into her hand.

"What the fuck are you doing, Sheri?"

"Relax. No one can see us, and the camera doesn't pick up this side of the room, which is why you chose it to watch porn. Keep watch while I show you how it's done," Sheri said as she set her teeth on the counter and sank to her knees.

There was a counter that obscured her from view once she was on her knees. She fished my cock out of my scrubs. "You got a big one here, boy." Sheri cupped my balls as she took me into her mouth. While she sucked me, she massaged my taint, pressing on prostrate.

She certainly knew how to charm a trouser snake. Sheri would clamp down on my dick with her gums when she moved out to the tip and then swirl her tongue around the head of my cock before going back for more. I was mesmerized by her talents and was torn between blowing my wad or prolonging as long as I could. I don't know how long she sucked me.

"Damn, Sheri. That's incredible."

Sheri gazed up at me, "Why don't you sneak into my room, and I'll show you what my cunt can do."

I followed her like a puppy, expecting a treat. And what a treat I got. Sheri dropped her robe and pulled her nightie over her head, showing her store-bought titties. Tattoos of band names adorned her torso and thighs. Sheri pointed to the bed, saying, "We should hurry before they notice that you're gone."

My cock throbbed as it pointed at the ceiling, waiting for her to climb on. Sheri's cunt was surprisingly wet. Maybe there's something to staying sexually active after menopause. After getting my tip in her hole, she impaled herself on my cock. "Damn. Six weeks is too long without cock. I was close to doing Fred, but he's recovering from a stroke, and I didn't want to kill him." she said as her pussy clamped down on my cock.

"Jeez_us, Sheri. Careful, you don't rip it off."

Sheri placed her hands on my pecs to brace herself as she started to go to town. She pivoted at the hips, slinging her cunt on my cock, whispering, "Suck my titties, boy," as her breasts hung in my face. Sheri rode me hard while I sucked and tweaked her nips. I suddenly felt a warm gush on my cock. "That's it, college boy. Suck, um, hard! Oh, God. I'm cumming," she hissed. She kept hammering my cock with her twat. "I want to taste that college boy cream, so tell me when you're ready to cum."

"You keep that up, and it won't be long," I grunted. I could hear squishing noises every time Sheri thumped her pussy onto my cock. She slammed herself down on my cock, squeezing my cock tight as she climaxed. Hearing Sheri quietly squeal in ecstasy was enough to push me over the precipice of orgasm.

"Here it comes, Sheri! I'm gonna shoot."

She was in the midst of climax and didn't get off quickly enough, and the first couple of squirts blasted her insides. Her mouth clamped over the head of my cock to catch the remainder of my college boy spunk. Sheri squeezed my balls while she sucked my dick, trying to get every drop out of me.

There was a quick knock on the door before it flew open. "Sheri, are these your teeth?" asked the night nurse, holding Sheri's dentures. The nurse, a shrew of a woman that everyone called Nurse Ratched, stood there for a second before she realized what she was seeing.

Sheri gulped hard, nearly taking the head of my dick off. "Un Hun," with my dick still in her mouth. We watched as Ratched set the teeth on the counter by the door and quietly backed out of the room. At first, I thought she hadn't recognized me and that we'd gotten away with it. It wasn't until the end of my shift that the facility manager stopped me on the way out, telling me they no longer needed my services. They didn't want any bad publicity, so they didn't report me. Even though it cost me my job, Sheri's toothless blow job was totally worth it.
