You agree

"Fine," you say with a knowing smile. "I wont knock you up if you become my personal fuck toy, my sex ****." Her eyes go wide and you can see her brain slowly, due to her pleasure, process the idea of being fucked like this whenever you want. Not being in control of her body ever again. You grunt, emphasizing the nearness of your orgasm. "Hurry up or you wont get to choose." She whimpers, nodding her consent, but you are feeling agressive and powerful so you growl out, "You have to say it and you better hurry up." A few tears streak dowm her cheeks, but her cunt tightens, increassing the squishing sounds going on between you. "I'm your personal fuck toy, your sex ****, your bitch. You own me." You smile, victorious. You pull out of her pussy, but shove into her ass without warning. She yelps, looking completely strikin. "I agreed not to knock you up, for now, and I'm not. However i did not say that I wouldn't cum inside you." You flood her asshole with a torrent of your hot seed and she moans loudly as she feels you let loss in her tight ruined asshole.
