Chapter 75: Kushina [4] (18+)

The warmth of his release still sat on her stomach in thick white streaks when Kael finally rolled to the side. Kushina reached for the drawer of the nightstand without sitting up fully, pulled out a small stack of tissues, and began to clean herself. She wiped the cum from her skin in slow, careful passes, folding each tissue once it was used and setting it aside. The red nightdress remained bunched around her waist. Her breasts were still bare from earlier, the nipples slightly tender where his mouth had been.

When she finished she glanced down and froze.

His cock was still hard. Fully erect, the head still shiny with oil and the last traces of his climax. She had felt how much he came. The amount alone should have been enough to soften any man. Minato had always needed time after a single release. This was different. The biology she knew did not match what she was seeing.

Kushina sat up a little more and looked at her son’s face. He was watching her with that same quiet intensity he had carried all evening. She did not know what to offer next. A handjob had already failed twice. She would not cross into actual sex. That line remained absolute in her mind. Yet the system of his body—whatever strange hunger drove it—clearly demanded more.

She was still turning the problem over when he moved.

Kael shifted behind her, the mattress dipping with his weight. A moment later she felt cool oil pour across the upper curve of her ass. His palm spread it in slow circles. Kushina’s back stiffened.

"Naruto, stop this. We can’t do this. Come here. I can help you with my hand."

His voice came low against the back of her shoulder. "It isn’t enough anymore, Mom."

He did not pull away. He stayed spooned against her back, one arm under her neck, the other hand still spreading oil over the soft rounds of her ass. When the skin shone he shifted lower, guided his cock between her closed thighs, and settled the hard length just beneath the folds of her pussy. The head rested against the soft skin where her thighs met. He began to rock.

The sensation was immediate and sharp. Her inner thighs were warm and slick from the oil and the leftover wetness of earlier. Every forward slide dragged the underside of his cock along that narrow channel. The head bumped gently against the lower edge of her pussy without entering. Kushina’s breath hitched.

"Ahh..."

Kael kept the rhythm steady and shallow at first. The wet schlick of his shaft moving between her thighs filled the quiet room. He reached around and squeezed one full cheek of her ass, fingers sinking into the soft flesh while he continued to thrust. Kushina’s hand came back and settled on his hip, not pushing him away but holding firmly, making certain the angle never rose high enough for him to slip inside.

"Naruto... this is... ahh..."

Her voice trembled. The protests were still there, but the volume had dropped. Each time the head of his cock rubbed along the sensitive skin just below her entrance a small sound escaped her. Kael pressed closer, chest against her back, and let his hips move in longer strokes. The oil made everything glide. Her thighs tightened around him instinctively, increasing the pressure.

He squeezed her ass again, harder this time, and felt her hips give a tiny answering roll. The wet sounds grew thicker. Pre-cum leaked from him and mixed with the oil, turning the channel between her legs even slicker. Kael’s breathing roughened.

"Ngh... Mom... feels so good like this..."

Kushina kept her hand on his hip, fingers digging in whenever the head of his cock came too close to slipping higher. She never told him to stop completely. The soft, broken moans that left her throat every few thrusts told him more than her words. He licked the side of her neck once, then settled into a deeper rhythm, fucking the tight space between her thighs with steady, wet strokes.

The minutes stretched. The bed creaked softly under them. Kushina’s breathing turned uneven. Her free hand clutched the sheet in front of her. Kael’s palm never left her ass, kneading and squeezing while his cock slid back and forth in the slick heat. Every forward thrust made the head nudge the soft lower lips of her pussy. Every backward pull left a shiny trail of oil and arousal on her skin.

"Ahh... Naruto... we shouldn’t... ahh..."

He did not answer with words. He simply kept moving, the wet pap-pap-pap of his hips against the backs of her thighs growing clearer. The pressure built slowly this time, heavier and more deliberate than before. Kushina’s thighs trembled around him. Her hand on his hip stayed locked in place, a silent reminder of the boundary she refused to cross.

When the climax finally rose he buried his face against the back of her shoulder and thrust harder between her legs. The wet sounds turned short and urgent. His cock pulsed. Thick ropes of cum spilled out across the upper curve of her ass and the small of her back, some of it sliding down into the cleft between her cheeks.

"Ahh... fuck... cumming... ngh..."

He kept rocking weakly through the last spurts until nothing more came. His cock remained half-hard against her, but the sharp edge of the need had eased for the moment.

"Mom are you ok?"

Kushina stayed still for several seconds. Then she turned in his arms. The movement pressed her bare breasts against his chest. She guided his head down and settled his face between them, one hand stroking the back of his hair the way she had when he was small.

"It’s okay, my boy. I’m okay. You just focus on yourself for now."

Her voice was soft and steady. Even after everything he had done to her body she still spoke to him like a mother first. Kael closed his eyes and breathed in the warm scent of her skin. The system window remained quiet. The quest was not finished, but the clause had been satisfied for the moment.

He stayed there, face nestled between her breasts, one arm around her waist, and let sleep take him while her fingers continued to move slowly through his hair.
