Like a woman possessed.

I drew out my cock and let it rest on her pelvis, nestling amongst her pubic hairs that covered the entrance to her slit. With my self-boosted fertility, I was already dripping precum, and it was clearly turning her on. She bucked her hips as her breathing grew shallow, **** for me to slide it inside her. She looked up at me, then reached down and held her pussy lips wide, inviting me to fill her up. "Please, Master. Fuck this slutty pussy of mine."

I leaned down, my mouth beside her ear as my cock now sat just outside her entrance, a drop of cum dripping off and landing on her inner lips. "Are you sure? You're awfully fertile right now thanks to my magic. Hell, I think if I were to just smear around that drop that's already landed on you, that would be enough to knock you up. Combine that with how fertile I am, if this cock goes in you, you'll certainly get pregnant. Might even end up with twins."

She gasped, at first pushing herself away, then lowering herself back towards it, until her hymen was pressed against the head, smearing precum all over her entrance. She tried to push herself down onto it, and winced in pain. "It... it hurts."

I nodded gently. "Sometimes it can hurt the first time if you don't stretch it out. I've got you, all right?" I slid a finger into her, slowly rotating it around to stretch the hymenal tissue. She gasped and clenched around me as I did, thighs quivering in pleasure. I inserted a second finger, making the same motion as before, gently widening her entrance so that my cock wouldn't hurt when I slid it into her. Finally, once I felt that she was relaxed enough, I began rubbing her inside wall in a repetitive "come here" motion, pressing against her G-spot again and again, driving her closer and closer to orgasm as I began sucking on one of her breasts. At last, she came, pussy clenching and unclenching around my fingers over and over as she cried out from the experience, squirting all over my chest in the process. Once again, I slid up towards her face, whispering in her ear as my cock rested outside her pussy, ready to fill her up.

"Do you want it, little slut? Do you want me to fuck you? Do you want me to get you pregnant?"

Her eyes were unfocused, but she managed to compose herself long enough to gasp out, "Breed me, Master."

As I slid into her for the first time, I could feel her insides clench around my cock at the experience, desperately trying to milk me for my cum already as I easily entered her and pressed against her cervix. She let out a choked moan, and I saw her eyes roll up in an unbelievably cute ahegao face.

"Hey there, little slut. How are you doing?"

She looked at me, struggling to stay focused on my voice as the newfound feelings of a cock in her pussy threatened to take away her attention. "I'm... doiNG..." she gasped as I pulsed my cock inside her, "great.....". Collapsing onto her back and wrapping her legs around me, I caught her murmur "breed me, masterrrrr." as she succumbed to the pleasure.

Well, with an invitation like that...

I pulled my cock out and slammed it back into her, slapping against her cervix with each thrust, enjoying the sensation of her spasming around my cock as she came again and again, my magically enhanced stamina allowing me to enjoy fucking her into she was laying in a puddle of her own cum, unable to speak. As I began to get close, I considered pulling out and letting her take her chances, but as I began to pull out, she tensed her legs and pulled me in further, making sure as much of my seed as possible went into her as possible as I came inside her.

Straightening, I looked down at her lying there, cum now dripping out of her, with her own juices splattering the insides of her thighs, and soaking into the towel that I'd placed on the bed. I began cleaning her up as she began to recover from the experience, and grabbed my water bottle so that she'd have something to drink afterwards. She'd lost a lot of fluids after all.

Oh my. What fun we are going to have. And to think, in time you'll be one of several beauties just like this.
