Rae, my sister, knocked and came into the hospital room. I was tied to the portable stretcher and lying there with slimy fuck all over my face and yet happy as a clam. In just about two hours I'd become responsive to Lara's pee, and Sis's, and I'd come like an orangutan this last time; there had been gobs of it that Lara had fingered into her cunt, to mix with her juices and have me suck out.
Sister gave me a sweet smile, and said, "I hope you two have been having fun.... Lara, how is he coming?" And she winked. "Oh, he's a real piss hound, now" said Lara. "Watch." She dipped her fingers into a beaker of her finest and held them under my nose. Instant wood. Sister smiled; "Well, Bro, you're not the same man that walked in here, are you?"
To Lara, she said, "I brought the items from your fridge; I have the box and the large bottle." I could see she had a large bottle wrapped in a white plastic, grocery bag. "And the latest item?" said Lara. "Yes, it's here."
To my utter surprise, Sis pulled a small, clear, plastic bag from her purse; I could see a used condom in it. She opened the bag and pulled out the condom, half filled, neatly tied. "It's from Garth."
"Thanks," Lara said, "I had to put it in the fridge yesterday afternoon." She turned to me, "Your jaw is hanging open, Bro. What's the problem?"
"You have Garth's cum, there?" I asked. "Yes, indeed. It was easy. Yesterday afternoon, I simply called him up and asked him if he'd like to donate his seed to science. He was flattered. I said, 'I'll bring a condom, and you fill it, and I'll take it to the lab.' You know, the male ego."
Sis said, "If he's rewired, there should be no problem getting him to suck the cum out of this condom." "I agree," Lara said. "I don't," I protested. "This is disgusting."
"Bro, said Lara, "let me help you." She dropped her jeans, pulled down her panties, and picked up an empty beaker nearby. "Watch." She held it to her soggy pussy and peed loudly into it, half filling the container with amber liquid. "Sound good? ...Well, it smells even better." She dipped her fingers in it, smelled them and wiped them under my nose. It was so fresh; her unmistakable aroma. My cock froze hard; it had a mind of its own.
She took the condom from Sis, and said to me, "Open up." I hesitated. She offered to beaker to me, for a sip, and I had one. Still I couldn't bring myself to eat my friend's cum. Sister said, "I have an idea for this disobedient brother of mine. Since he likes your piss so well, let's let him drink down Garth's cum mixed in your piss. ...What do you think of that, Bro?"
"Well, it's better," I said. "Probably I won't even taste it." Lara squeezed the goo out of the condom, and into the beaker. I could see the strands of cum floating in the golden fluid. She held it to my lips, and there was the faint disagreeable odor of Garth's cum, but masked well by the tangy scent of her piss. I felt my opposition melting and my cock was jumping. "OK, I'll drink cum with your pee, Lara."
"But Lara, don't you think we should add a little something, to spike this brew?" said Sis. "My thought, exactly; you have the box there. Let's use its contents."
Sis opened the box; it looked sort of like a fisherman's box, and sure enough, inside were many compartments. In each compartment, neatly tied, was a condom, filled.
"Your frat brothers," said Sis, watching me closely. "How the...?"
Lara spoke up. "Rather simple. I just posted a note yesterday morning on the frat bulletin board saying "Wanted: semen samples from the real men of Sigma Chi. Call... if interested. A collection time, at the frat house, will be arranged." I got 20 calls in a hurry, and so I went there that afternoon--I'd told them all the same time.
"I announced, 'Guys, studs, I don't have much time, but if you'd fill these condoms quickly, you'd really 'make' my science project. I'm studying the properties of semen, in and out of its natural surroundings. Please sign here.' And I also asked three of them to participate in a further study. Well, in 10 mins I had 20 condoms filled, tied and stashed. The guys were ever so generous."
Sis chimed in, "Here's what we're going to do, Bro. We're going to empty all 20 of them into Lara's piss-- _then_ you will drink." Before I could say anything, the two of them began untying the condoms and emptying the goo into the newer beaker. In no time there was a mass of whitish fluid in with Lara's more liquid urine. Lara stirred it with her finger, looking at me. When she brought it under my nose, the scent of day-old cum was very strong, though her pee aroma was still there. I felt a little sick, but strangely thrilled at the depravity of it.
