BEEP! BEEP! BEEP! It was only 5:30, but I had already been awake for some time. I got out of bed and into the shower. If I leave by 8 then I should have plenty of time to get there. Classes didn't start for a few days, but obviously they wanted Freshman there a bit earlier to get used to campus. I was making the drive alone, I didn't want my family going with me, I knew that they'd get too emotional. 

After I get out of the shower, I make sure to polish my chest spike, then go triple check to make sure I've packed everything. I won't be able to come back home until at least Thanksgiving, so anything I could feasibly use for the next 3 months went in my suitcase. 

After all that, eating breakfast, and making sure my room was clean before I left, it was already 730. I went out to the kitchen to say goodbye to my parents. After some tearful farewells, I went to my sisters room, and knocked on the door.

"Come in" she responded

"Hey Eve." I said in a seductive tone. "I've got a big surprise for you before I leave" 

Eve is my twin sister, and she's staying local for college, so she can just stay at home. 

"Now you've got my interest Julian" she responds also seductively.

"Well I figured" I explain while pulling down my pants "it's the first semester of freshman year, so I'll be too busy for a girlfriend or boyfriend"

"And where do I come in?" she asks

"And you could be too. But you'll need some relief" I say, My erect cock now on full display.

I reach down, grab my knot, and effortlessly pull my penis right off.

"Basically, you'll need this more than I will." I say, handing her my throbbing shaft. "You can keep it until I come home. If I need one before then, there's a mod shop on campus. You have complete and utter free reign of my cock.

"Thanks Julian, I'll be sure to take good care of it." She responds. "A few questions though"

"Ask away" I say

"Can I let my friends borrow it" 

"Its your cock not mine the second I step out the door. Do whatever you feel is right. Use it as a dildo, attach it to yourself, eat it, whatever."

"Ok. Also, what do you mean by 'until I come home'?"

"Basically, I might take it back after thanksgiving. If not though, it's yours to keep."

"If it survives until then" she says coyly "final question, is there any time where you don't want me to use it"

"Try not to when I'd be in class, but again, it's yours until thanksgiving.

"Cool. Well I'll be seeing you"

"See ya" I say, leaving her room.

--------------------------------------------------------------------

I arrive at campus a few hours later. The whole way up, I felt occasionally pokes to my glans and balls, and even strokes to my shaft. She knows how long the trip takes, and it's probably only a matter of time before she goes to town on my -her- penis. I get to the information table, get my dorm key, and race up. 12:30. 

"You have 20 minutes." I text her. "Go ham".

Within a few seconds I begin to feel my tip teasing her labia and clit, before being plunged deep in her. My former cock being no more than a living dildo as she vigorously thrusts it in and out of her cunt. Her movements grow quicker as I feel her get wetter. After a few minutes, she slams her toy in to the knot as it cums. The orgasm is like none I'd ever had before.

She didn't take it out for a while. I could feel it trapped in her vagina as I went through all the orientations of the day. That night, I return to my dorm, my former penis still clenched tightly into her pussy. As I'm sitting there scrolling the web I feel it finally pulled out of her. I breathe a sigh of relief, before immediately feeling my tip assaulted by her tongue. This is going to be one long semester
