... cum first. That's an important part that helps a woman to get pregnant. The wetness gives the sperm cells liquid to swim around in, so that more of them stay alive in the vagina long enough to actually make it up into the uterus."

"Okay, so what do you want me to do, miss smarty-pants?"

"I want you to pull out of me for a few minutes, so that I can flip over onto my back and masturbate while I'm looking at your dick and balls. I'm pretty sure that's the fastest way I can make myself cum."

I begrudgingly eased my dick out of Lacey's awesome-feeling vagina, and sat back on my haunches, as I watched her quickly flip over onto her back on top of the bed, and then skillfully manipulate her clitoris until she finally gave herself what looked like a fairly decent orgasm.

Just for the record, Lacey had kept her eyes laser-focus on my package the whole time that she was masturbating in front of me.

Lacey finally got back into her previous doggie-style, down-on-all-fours body position--this time, remembering to place a pillow under the front part of her hips and pubic area to assist her in maintaining her butt-up-in-the-air, doggie-style pose--and she said to me, "Fuck me now, God damn it!"

Lacey kept clamping down then loosening up her strong vaginal sphincter muscles while I tried to keep thrusting my dick in and out of her vagina as best as I could. But it was a losing battle.

So I pulled out until I had only the head of my dick inserted up into her vaginal entrance, and I just stayed in that position without moving my dick around, while I was letting Lacey's strong vaginal muscles work their milking magic on my frenulum, just behind the head of my dick.

And it didn't take long for the orgasmic feelings to overwhelm me, at which point I shoved my dick up into my sister's vagina--all the way up to the hilt--and squirted my whole wad deep inside my little sister's baby-making hole.

Afterwards, when Lacey felt me starting to pull out of her, I felt her vaginal muscles clamp down tightly around the ...
