Unprotected sex

Naruko licked her lips this might be no she needed this dick of Sasuke in her life. She began stroking Sasuke's cock feeling it harden in her hands. "Your prize is raw sex no condoms at all. Now fuc-!"

She didn't even get to finish as Sasuke shoved his bitch breaker cock into Naruko's pussy causing her to moan as most of her one night partner's preferred anal she even stopped using birth control entirely figuring most would pull out or do it there. But the look on Sasuke's face screamed he was going to make sure his mother had grandbabies with how hard he was fucking her and Naruto he was fapping away watching his sister being fucked by his rival.

Naruko's generous bust was groped firmly by Sasuke's firm hands as an indent from his cock could be seen in Naruko's belly with each thrust as it began to twitch signalling the end as Naruko hit her first mind numbing climax drooling more as she barely got out "N-not inside!!" She got out before her brother Naruto said. "Come on Sasuke don't back out now. Or well I guess I'll win by just cumming once in Hinata."

He smirked as Sasuke growled and Naruko paled as he pinned her to the ground slamming into her one last time cumming directly into her womb.. and once her womb was filled with the Uchiha sperm a seal appeared on Naruko's belly causing a few more eggs to be pumped in to her womb to be fertilized.. likely by being pumped full by such a strong Shinobi.

It was Kushina's handy work to make sure she got plenty of grand babies when Naruko finally got off birth control. "Damn it mom." She cursed before biting her thumb and drawing a seal on Sasuke's belly smirking. "And with this your mine." Sasuke looked at Naruto who was running now.

Naruko huffed. "Since you cummed in me you'll be taking responsibility and becoming my play toy." She smirked licking her lips. "What to do with you so many things I can even gift myself your pair and make you a girl. Maybe I should make you a femboy or other things maybe I'll make you a girl to suck Naruto's cock? Or I can fuck your mom with this mighty cock."
