Only a week

I was feeling worried. Me any my girlfriend Hannah had started dating not that long ago, but just when we had planned a romantic week of summer she got her mandatory service.

That is, a futa can select a girl she knows to serve her. Normally this is for life, unless the selected girl has a girlfriend or another futa they want to serve instead.

If she had a boyfriend it was normally an entire month until she was free. But if she chose another futa and said she had a boyfriend then it would only be a week with that new futa.

I tried to wrack my brain for who could have asked for her initially. But we only knew one futa that I could think of. She was a classmate of ours, very open about the people she's sleeping with. I shook my head clearing the image of the proper looking student president showing up one day looking sloppy and cum streaming between her legs.

I had to **** my erection down remembering that sight. The culprit of that image was Emily, a student the same age as us. It wasn't a guess who the parent was as all the girls in her class had ended up pregnant within the first year... Including the teacher.

Hannah looked at me grimly. "Don't worry I took care of things. I know we had this whole thing planned but we can put it off for a week." It made me wonder who this other futa she chose was.

She smiled weakly. "Don't worry. It's only a week."

She buried her head in my chest as we hugged. I felt like she was crying inside so I spoke up trying to comfort her.

"It's fine, I know it's a mandatory thing after all." I tried not to think about about the countless porn videos that had been produced by futas, or more accurately how large their cocks were. Generally larger than any male could get, not to mention that a cock that size was going to be attended by my girlfriend.

I failed to hide my erection when I imagined my girlfriend's fit body pressing up to a large cock. I blushed when she looked up at me with an accusatory eyes.

"Hey! I can't help it... I watch a lot of porn... Just thinking about you in those positions-" I stopped myself I could tell my position was plummeting quickly in her eyes.

She broke away from me with a huff. "Well, I managed to convince them to start tomorrow rather than tonight so we can still have our dinner."

She turned to me with a teasing smile. "I might even perform some of those positions for you after we're done." She turned away as she continued. "Mom had already prepared something for our getaway week anyways."

With that she left my house.

I tried to refrain, but before I knew it my imagination was feeding me images of Hannah, modest breasts swinging wildly as she was on all fours in front of a futa with massive breasts. I blew my load into a sock before I decided to tell my mom I wasn't going to be here tonight.

I 100% blame my mother for these fantasies. Further confirmed when after sending her that text message. "Oh! That's great that means I can bring my friend's home tonight."

Those friends of hers? They were porn stars. Yes I had watched my mom's porn online. I even sat with a few of the futa that regularly fucked her like everything was normal. It was a bit confusing at first seeing my mother's face like that, almost unrecognizable. Then the next morning finding the same two people acting normally for breakfast. At least mom managed to hide what happened incredibly well.

I had only found out because I saw her smiling face in a thumbnail. From then on I knew what to look for, if I woke up one morning and saw a friend of hers there would be a new video for me to watch.

I made myself presentable. I was meeting Hannah's mom after all. So with a nice shirt and pants I stepped out of my house to head to my girlfriend's house.
