The stranger stayed the night. The next morning, all three of us were in the shower room together. I enjoyed watching the stranger's petite body next to Adele's bigger, more shapely frame. The stranger's almost flat chest really made Adele's lovely, cone-shaped small breasts stand out. I could see countless interesting details in both of their bodies, details that were best visible in a comparison like this. Their bodies really complemented each other. It was time to bring the two closer again, in a humiliating yet arousing way.
"Get on the floor, legs spread, ass up," I commanded Adele, who then got down obediently. I took my hands to her buttocks, spread them forcefully and continued, looking at the stranger,
"Just look at this sweet asshole Adele has. It's like a small star, now all clean and shaven. And it feels wonderful around my cock, too. Now, tell me, have you ever licked anyone's ass or had yours licked?"
The stranger looked baffled, bit her lip and mumbled "What? No."
"Now's a good time to try something new, then. Get your face between Adele's buttocks and give her some tongue."
"But, I don't... I'm not sure I can," the stranger stuttered.
"Get over here now, or get out. It's not that hard. You're only going to get punished by hesitating like that."
The stranger looked puzzled and didn't seem to have the willpower to make a choice quick enough, so I decided to help her out. I lightly grabbed her by the hair, led her behind Adele and shoved her face between Adele's buttocks. That was actually the first time I had touched her.
"Now lick, with proper enthusiasm, or we'll go on from were we left off yesterday. That is, were going to tie you up and try a number of sharp, stinging instruments on your pussy, covering every centimeter from your clit, all the way down to your asshole, with deep red welts," I threatened.
This did the trick. Hesitantly, the stranger closed her eyes, pushed out her tongue and slowly brought it on Adele's beautiful anus. To make sure she really understood what I meant, I removed my belt from my pants and reminded,
"Lick her properly, show Adele how you love her hole, or else we'll start your punishment with this belt, right now."
The stranger seemed to get over her initial disgust pretty well. She tongued Adele's asshole much like she had licked her pussy the previous day, working it intensely. Adele seemed to be enjoying this and shortly she asked, panting, "May I touch myself?"
"Yes, go ahead," I answered. "The both of you should have your fingers work your clit while doing something like this."
The stranger, too, took her hand between her legs, still licking moaning Adele's anus obediently. I let her go on for a good while, making sure her tongue got a decent workout. I then fetched a small bottle of lube, handed it to the stranger, and said:
"That's enough licking for now, but I'm sure you'll get the opportunity to bury your tongue in Adele's ass again. Her ass can really take a lot and I want you to try it out for yourself. Lube her nice and well and see, how many fingers you can get inside her."
The stranger started by coating her index finger with a bit of lube and slowly inserting it. Adele didn't react openly, but she soon started masturbating again, obviously not very opposed to all this - yet.
"Stop playing around! Put some more lube and push more fingers in. Her ass can easily fit your whole hand. You can, actually, try that too. Use force if you need to, she's used to that," I insisted.
Adele gave me a nasty look, but soon turned her head back down. The stranger had three fingers in, and it seemed her movements already caused Adele occasional discomfort. Adele yelped loudly when a fourth finger was added.
"That's it. Push them in, don't be too gentle," I commented.
The stranger seemed to get excited over this. She was now pushing with all her five fingers, trying different angles and finger positions, adding more lube to get past Adele's tight sphincter. Adele yelped and even shouted, whenever the stranger added more force to her endeavor.
"Aaagh, please, not so rough! Oww."
I went to the pile of clothes on the adjacent bench and pulled out a pair of the stranger's panties. They were small and white, showing a good dried up patch of her juices in the center. I handed them to the stranger and said: "Gag Adele with these, she's making unwanted noise."
Adele looked disgusted but obediently opened her mouth when the stranger proceeded to shove her dirty panties inside.
"Now, go on stretching her ass."
The stranger brought her fingers back to Adele's much-dilated hole and was soon trying to fit all five of them in her, showing very little hesitation or concern over Adele's muffled shouts. This anal abuse went on for some time, and at best she managed to get just about past her knuckles, to which Adele responded by screaming really loudly. It was time to change the roles again.
"Great, that's enough for now," I commented to the stranger. "It's time to give your ass something, too. Tell me, have you ever been assfucked?"
The stranger suddenly looked scared and answered, "No... For me, it's, you know, very sensitive. Even a finger's bad." She must have realized the irony of the situation.
"Would you let us punish your ass, or teach you to love getting your sensitive hole pounded?"
"I, well... . Please, be gentle, if you have to... do that," she answered pleadingly.
"Good. Get down on the floor, just like Adele is. Adele, get up and go get the enema bag - and take those panties from your mouth."
Adele, looking somewhat hurt and angry from the previous abuse, left to get the equipment. The stranger got down on her knees, bent over and now her beautiful, wrinkly anus was nicely displayed above her white-haired, perfect pussy. Adele soon came back with the enema gear and I filled the bag with warmish water.
"Adele, give her the enema. Just put the nozzle in, hang up the bag and let the water out with full pressure."
Adele, still looking angry, quickly hung the bag and shoved the small, plastic nozzle in forcefully, which made the stranger yelp. Adele opened the nozzle and soon the stranger was squirming and moaning, apparently not enjoying the sensation. I waited until the bag was empty and then said:
"Stand up, facing us, and don't even think of letting a single drop escape. If you do, you'll get another enema, twice the size, and we'll cane your asshole the whole time you're holding it in."
I then continued: "Let's get to know you better. Now, you've never been fucked in the ass. Have you ever had sex with multiple partners at the same time, or sex with a woman?"
"No, not before this."
"Have you ever been sexually punished before?"
"No."
"Have you ever been pissed on?"
"What? No, never."
She looked a bit distressed upon hearing this question, but I couldn't tell whether it was just caused by the enema she was clearly having trouble holding in.
"Have you ever been sexually controlled or humiliated?"
