Your {If Anal Girth>10}gaping ass{endif}{If Anal girth<10}loose ass{endif} yearns for a dick to fill it. Rather than leave like she usually does, Anna hesitates.

“Like what you see?” You giggle slightly as she turns back. You see her cock looks positively engorged.

{If Anal Girth> 9}You know your ass is gaping? This should go right in…”{endif}{if Anal Girth<10} This might be a bit of a stretch…{endif}

You watch her cock, doubled in thickness, hang heavily between her legs. Your body gets warm as she nears. This is going to be different.

The penetration this time is more satisfying. Your {If Breasts=1}A cup{endif}{If Breasts=2}B cup{endif}{If Breasts=3}C cup{endif}{If Breasts=4}D cup{endif}{If Breasts=5}DD cup{endif}{If Breasts=6}DDD cup{endif}{If Breasts=7}E cup{endif}{If Breasts=8}EE cup{endif}{If Breasts=9}EE cup{endif}{If Breasts=10}F cup{endif} breasts tingle as Anna bottoms out. She pushes her breasts against yours this time. You hook your legs around her to keep her from pulling out too far.

“This feels different,” you moan. “I want whatever you are going to give me.”

“You are going to get pregnant for real this time. Your body is ready because of all the chemicals in the cum you’ve taken. Ready?”

“I don’t know if it’s the hormones talking, but I don’t mind that. It’s what a body like mine is for, right?”

“Right. And I’ll keep visiting you as many times as you need and I’ll knock you up again after if you want, too!”

Anna cums a load appropriate for her balls. You grow so big your belly outgrows your torso and doesn’t stop until she is drained.

Like usual, nothing is wasted once she pulls out. Your see her balls have shrunken to a mere tennis ball size once she sits behind your head on the sofa.

“I got it all this time?”

“Every drop. I’m going to hear about it back at the office,” she sighs.

“Don’t forget to massage your breasts so the milk production gets simulated.” Anna squeezes your tits to demonstrate.
