Harold sat on the edge of his bed in the cheap motel room, his seventy-year-old hands shaking as he pulled off his shirt. His cock was already half-hard just from the messages they'd exchanged. Mike was forty-six, thick build, and blunt as hell in every text. "Gonna stretch that virgin ass and fill it," he'd written. Harold had never done anything with a man before. Sixty years of marriage to his wife, then five years alone, and now this.
Mike walked in without knocking. "Strip," he said, voice low and direct. Harold stood and dropped his pants. His cock bobbed free, thick and veined, the head already leaking. Mike grinned and shoved his own jeans down. His dick was longer, heavier, already stiff and pointing up. "On the bed, old man. Face down."
Harold climbed on, ass up like Mike told him. He felt exposed, the air cool on his hole. Mike's rough palm spread his cheeks. "Look at that tight pink ring. Never been fucked, huh?" A finger pressed against it, dry at first, then Mike spat and rubbed the spit in. Harold grunted when the finger pushed inside. It burned, but his cock twitched against the sheets.
"Relax," Mike said, working the finger deeper, twisting it. "Gonna need more than that." He pulled out, squeezed lube straight onto Harold's hole, and pushed two fingers in. Harold hissed at the stretch. Mike pumped them slow, scissoring, getting him open. "Your ass is gripping me already. Bet you been thinking about this for years."
Harold nodded into the pillow. "Yeah. Never told anyone."
Mike added a third finger. Harold's hole clenched, then gave. The burn turned into a full feeling that made his balls tighten. Mike finger-fucked him steady, knuckles bumping his rim each time. Harold's cock leaked a steady string onto the mattress. "Fuck, that feels good," he muttered.
"Wait till you get the real thing." Mike pulled his fingers out. Harold heard the rip of a condom wrapper, the wet sound of lube being stroked over Mike's cock. Then the blunt head pressed against his hole. "Push back on it. Let me in."
Harold took a breath and did it. The head popped past his ring and he groaned loud. It was thicker than the fingers, stretching him wide. Mike held still, letting him adjust. "Breathe. That's it. Halfway already."
Inch by inch Mike sank deeper. Harold felt every ridge, the way his ass walls had to open around the shaft. When Mike's balls finally pressed against him, Harold was panting. Full. Stuffed. His own cock throbbed untouched.
Mike started moving. Short thrusts at first, then longer ones. Each slide out dragged against Harold's prostate and made his toes curl. "Fuck, you're tight," Mike growled. He grabbed Harold's hips and picked up speed. Skin slapped. The bed creaked. Harold pushed back to meet every thrust, grunting every time Mike bottomed out.
"Harder," Harold said, surprising himself. Mike obliged, pounding now, the headboard knocking the wall. Harold's hole burned in the best way, stretched and used. Pre-cum dripped from his cock in long strands. Mike reached under and gave it a couple rough strokes.

"Gonna come with my dick in your ass, old man?"
Harold nodded, words gone. Mike angled his hips and nailed that spot inside him over and over. Harold's orgasm hit sudden and hard. His cock jerked, shooting thick ropes across the sheets while his ass clamped down on Mike's shaft. Mike fucked him through it, then slammed in deep and came with a low growl, pulsing inside the condom.
They stayed locked together a minute, breathing hard. Mike eased out slow. Harold felt the empty ache right away, his hole twitching and loose. Mike peeled off the condom and wiped him down with a towel. "You took it like you were made for it."
Harold rolled onto his back, legs still spread. His cock was softening but interested again. "Again," he said. "Want it again."
Mike laughed, already stroking himself back to hardness. "Old man wants more cock. Good." He rolled Harold onto his side this time, lifted one leg, and pushed back inside with one smooth thrust. Harold moaned at the fresh stretch. Mike fucked him steady and deep, one hand on Harold's chest, the other jerking his cock in time with the thrusts.
Harold came again, smaller but just as intense, ass milking Mike's dick until Mike filled the second condom. Afterward they lay there, sweat cooling. Harold's hole felt sore and open, cum and lube leaking out when he moved. He liked the feeling.
Mike lit a cigarette. "Same time next week?"
Harold nodded. "Yeah. Next week." He already knew he'd be counting the days until he could get that thick cock back inside him. First time was done. He wanted every time after.
