He started stroking his cock with slow, long strokes. He pictured bending her over the kitchen counter, shoving her jeans down, and sliding into her from behind. He imagined his hands reaching inside her sweater to squeeze her big tits.
The rhythmic squish, squish of his palm sliding back and forth over his cock sped up. As he came hard, lost in his fantasy, he groaned, “Oh, Mom.” His hips jerked as thick ropes of cum hit the shower wall.
He stood there with the water still pouring over him and feeling the bliss of the physical release. He also experienced the wave of mental clarity that follows orgasm. His mother was in the house, and she could knock at the door any minute.

While Mark was getting in the shower, Linda stood looking at her bedroom closet. She didn’t have a single pair of her husband’s old pants and not even a forgotten T-shirt. She had finally cleared everything out months ago. It felt good at the time. Now, it felt like bad planning.
Her eyes landed on a silky little blue robe she sometimes wore in summer. It was short, mid-thigh, satin. She smiled before she could stop herself, picturing Mark in it, the fabric barely closing across his big chest, the hem riding high on his thighs. She felt butterflies in her belly at the thought. God, she thought, I wouldn’t mind seeing that at all.
She caught herself. Stop it, Linda. Good Lord, you are too horny these days.
She grabbed the only sensible choice, which was a thick white terry-cloth robe. That would have to do.
She carried it down the hall, scooped Mark’s pile of dirty clothes from the floor, and balanced the bundle against her hip. The shower was running. She meant to just crack the door, toss the robe on the vanity, and leave.
But when the door opened a few inches, the big vanity mirror gave her a perfect, unobstructed profile view of Mark straight through the clear glass shower doors. She froze.
He stood under the spray, his head leaning against the tile. He was six feet of solid muscle. Water was streaming down his back, over his broad shoulders. His ass was round, firm, flexing every time he shifted his weight.
His cock was in his hand. It was fully erect and bigger than she remembered his father ever being. He stroked himself slowly at first, then faster. She watched the muscles in his back tighten, watched his fist move, and watched him come. In a low groan that carried faintly over the running water, he said “oh, Mom.”
Linda’s breath stopped. Her nipples stiffened against the inside of her bra. He pussy tingled. She couldn’t move and couldn’t look away, not until the last shudder left his body and he leaned there catching his breath. Only then did she ease the door shut. Her heart was pounding so hard she was sure he’d hear it through the wall.
She stood in the hallway a moment and pressed the robe to her chest.
Then she knocked twice, light and innocent. “Honey? All I could find was a robe.”
Mark’s voice came back, a little hoarse. “That’s fine. Just… leave it outside, I’ll be done in a minute.”
