I opened the door and looked down the hallway. The coast was clear and I stepped next door back into Abby's room. As I left Catie's room and her in bed it felt, well,...I've never been able to describe it. It was as if I were a book out on loan from a library or a videogame or movie out on loan from a video store to provide short-term sexual gratification for the people I was being loaned to.

I stretched out on Abby's bed, waiting for her to come back. She sure seemed to be taking a long time in the bathroom. I thought about going downstairs to empty my bladder but waited instead. At long last Abby arrived back in her room and she was carrying two closed-top combination enema bags that looked somewhat larger than the ones that Catie and I had. What was different, besides the volume, was they both were equipped with bulbous head curved nozzles. I got up to close the door while she laid them on the bed.

"The two coat trees are in my closet. Will you get them?" Abby asked. I opened one of the closet doors and sure enough, there they were. She asked me to take them around on the far side of the bed and stand them next to each other, which I did. I watched her hang the bags up. They sure seemed larger. I told Abby that I'd be right back, that I was going to the bathroom. Once again, a quick look down the hallway and then down the hall, naked.

Seeing Abby carrying those bags already made me hard again and when I got to the bathroom, I had to relax a bit and tilt my pelvis so that I could empty my bladder. Clearly, enemas were on the menu tonight and an empty bladder was going to be a necessity (this was before the days where I would add salt or baking soda to reduce water uptake). After I was done and flushed the toilet, another look down the hallway and then a quick and quiet walk to Abby's room. I slipped through the doorway to her room and closed the door quietly.

"Lingerie on or off?" Abby asked.

"You look really good with it on, but I like the feeling of skin on skin. So, let's take it off."

"Stockings, too?"

"Yes, stockings, too."

I came over to help remove her bodysuit and her stockings. I put them beside the bed and looked to see what was next.

"Sis says you both like fucking while taking and holding enemas?" It was a question more than a statement. I told her yes.

"She says she likes to feel you inside her while she gets filled and then to feel you cum inside her once she's filled with warm water."

"She does like that. So do I. There's something about her being on top of me while we're both filled that feels so different and so good. Just don't fill too fast."

"I want to try it," Abby said.

I was on my back and spread my legs. She pushed the nozzle up inside me. She leaned over my torso and took my cock into her mouth and gave me about two minutes of intense sucking before climbing onto the bed and straddling me.

She handed me the other nozzle, placed my cock at her still dripping vaginal opening and let me insert her nozzle into her. As soon as I pressed the nozzle in, she sank my cock back inside her.

It was still tight being inside her though she was extremely well lubricated. She started riding up and down on me and commented on how strange and how good it felt to have the nozzle inside her, to feel it move around inside her as she moved up and down on my cock.

"Wait until you start feeling the enema fill you," I said.

The curvature of these nozzles and their bulbous tips made it easier for the nozzles to remain in place during our sexual activity. Abby told me that it was quite the sight in her closet mirrors to see our bags hanging behind us as she was on top of me. I tried to bend around to look at our reflection in the mirror. I couldn't get as clear a view and we were a bit constrained by the length of the hoses.

After five minutes of penetration and stroking I had Abby stop for a moment. She reached behind her and released the clamp on my enema bag. I released hers and we both set them at one "click" from wide open. It took about 12 minutes for each bag to empty and flatten. My bag emptied and flattened before hers. Nonetheless, we were both reasonably "full" at 10 minutes.

Abby had continual orgasms once her bag was about half emptied into her. Of course, I helped her along as much as I could by sucking her breasts and playing with her nipples. She seemed to find the correct angle to keep the orgasmic stimulation going. It also felt good to me. I always thought that with these enemas, that it felt warmer inside Catie when I was sliding in and out of her vagina. I felt the same sensation with Abby. It was just warmer inside her this way.

"Are you doing okay?" was my check-in with Abby and her taking and holding of her enema.

Catie and I were experienced at this kind of sex, but this was new for Abby. Twenty one minutes after Abby had begun sliding down my cock I told Abby that I was getting close to cumming. Three minutes later I was spurting my cum inside of Abby once again. She laid down on me (gently to keep a certain amount of pressure off our stomachs), her head tucked in above my shoulder at my neck.

Abby finally raised her head and she began kissing me with these little kisses until she reached my mouth when the kiss(es) turned into tongue-probing kisses. When we had our fill of these kisses, Abby asked me if Catie and I ever had enema sex when I was on top. Of course, Catie wasn't my only enema sex partner and Abby knew that. But she was asking about Catie and I.

"Oh, yes. But it's easier with her on top than it is with me on top."

Abby was ready to get up and release her enema. I had closed the clamp on her hose and bag and pulled the nozzle out of her rectum. I had already slipped out of Abby's vagina and there was a pool of my cum forming on my abdomen from what was dripping out of her. She carefully got up from the bed, briefly took my cock in her mouth with a little sucking action, and then she left to go down the hall to the bathroom.

I was doing okay holding my enema. I wanted to release, too, but I was managing to hold this enema in. I was thankful that I wasn't trying to hold two bags inside of me. Abby returned in a little over five minutes and she pulled the nozzle out of me and sent me down the hall to expel my enema. It came out in long continual streams and I released most of it in the first couple of minutes. A couple of toilet flushes and clean up and I was reasonably empty. When I returned to the bedroom, she had moved the coat trees and the enema bags to the other side of the bed up near the headboard. The pillows and towels were rearranged so that we would be laying along the long axis of the bed rather than across it as we had been thus far.

Abby got up and briefly left the room to go back to the bathroom. I assumed that it was to release a little more of her enema. I found out later that it was to release what was left and to perform a quick rinse of her rectum with a bulb.

I was laying on my back in her bed waiting for her to come back. I wasn't covered. She finally returned, crawled up the bed to me and told me that I wasn't done yet. Now that she was all cleaned out she wanted me to cum in her ass (again). She thought the anal sex we experienced in the previous month was interesting. She wanted ME to clean her first, though. And so we started the next round with me licking my cum out of her pussy.

It didn't take her long before she was arching her back in response to my tongue. Not only my tongue. While my tongue was sliding in and among the folds of her vaginal lips and slipping in and out of the opening where my cock had been just a little while earlier, I was also reaching up to her breasts and manipulating them, too. At one point she drew a pillow over her face as she arched her back to keep the sounds emanating from her throat muffled and quiet. My tongue, lips, hands, and fingers were relentless. After one particularly intense orgasm, she was breathing heavily as I let her recover.

"God, you've got to do that to Stephanie, Ann, and Delaney. They don't know what they're missing," Abby said. I knew who they were and had met Stephanie previously. The other women I knew to be Abby's sexually active friends in high school. Apparently, they referred to themselves as the SAADists, creating an acronym from their first names. Abby added an extra "A" to their group name.

"I'm not sure that's a great idea," I said. It was already risky enough to be here in Abby's bedroom in the very early morning on Thanksgiving (even with Catie's blessing). It was completely different to expand that to Abby's friends. Abby didn't press me any further on this in the moment.

I told Abby to turn over on her belly. I knew she had a tube of lubricant in her nightstand and I took it out so that I could begin the lubrication process. I squeezed out a large dollop onto my middle and index finger, put the tube down, and with my left hand spread her ass cheeks apart to insert my fingers to spread the lubricant around. She reached back with both hands and spread her cheeks even wider.

My fingers slipped in relatively easily and I twisted them back and forth to lubricate the inside and the outside of her anus and lower rectum. By feel, she was quite clean inside. I squeezed out a second dollop onto my fingers and this time inserted three fingers beyond the middle joints. It stretched her nicely as my fingers curved around and stimulated the inner muscle ring. Satisfied that she was well lubricated, I pulled my fingers out of her and rubbed whatever 'excess lubricant' was on my fingers onto my cock.

She had her face turned to the right so that she could watch all of this in the mirrors of her closet doors. She watched as I came up from behind her spread legs and slid the tip of my cock towards her lubricated anus. Even though she was watching, the first contact of my penis with her anus caused her to 'jump.' But with slow steady pressure and then pulling back a bit every half-inch or so, I worked my cock into her rectum. Eventually, my lower abdomen and hips made contact with her buttocks. I gradually increased the pace of sliding in and out of her and the length of the strokes.

I could see Abby grabbed the bed at times when I pressed deeper and occasionally when place her face in the pillow before turning back to watch herself and me. After about 10 minutes of this, I gently grasped her hips to pull them up in the air into a doggy style position. She kept her head down for a few minutes watching in the mirror before finally pushing herself up on her knees and hands. I was getting pretty deep into her with her in the ass-up position. But when she came up on all-fours, she interlocked her fingers and hands with mine and started to rock back to meet each stroke. And with each impact of my hips, there were little ripple effects visible to me.

It kept getting more vigorous as time went on. Abby was losing a bit of control and I had to remind her to keep quiet as the pounding got more intense. Finally, I came up on my knees, my hands on her hips to help guide her back as I thrust my cock into her rectum about twice per second. I watched the ripple effect of each impact and now there was the audible "slap, slap, slap" of each stroke as my hips met her buttocks. This was much more vigorous than I had envisioned her taking.

She asked me if I was going to cum.

"Not yet!"

"Well, I am!"

With that her face dropped to the pillow, she reached back with her right hand and brought it to her clitoris. She started shaking in addition to moving with each thrust I was giving her. I reached down with my right hand and brought it to cover hers and press against her pubic area while maintaining the rhythmic strokes. Her eyes were barely open as she/we watched this ass fucking in the mirror. In short, breathless phrases she was saying that she wanted me in her. I reminded her that I already was.

"No, in my pussy, too. I want you in both places at once."

Well, that wasn't possible. But I remembered, in the moment, a conversation about multiple sex partners and gangbangs....

She finally let her legs drop back to the mattress so she was on her belly. I 'followed' her down.

"I need to rest for a couple of minutes," she said. I placed my legs outside her so that my hips rested on her buttocks and otherwise I wasn't compressing her. Her breathing slowed down and I asked if she was okay. She acknowledged that she was and that it was the intensity that had her feeling breathless. It was in this moment of rest that I asked her if she was still the only one in her group of friends that had had anal sex. She told me that Stephanie had recently tried it with a boyfriend and that, as far as she knew, her other two friends had not.

"You were getting pretty intense," I told her and that I hadn't expected her to be that vigorous and even willing to be that vigorous.

"It just started to feel so good!" she told me.

I was still hard and inside her rectum. I asked if she was ready to explore some other anal positions and she indicated she was. I told her I was going to try to stay in her while we rolled to her left side. I did so successfully and we ended up in the anal spoons position.

"This is a nice position for a morning wakeup or if you want to go to sleep with a cock in your ass," I told her. We pulled our legs up a bit and I showed her the very shallow and gentle strokes that were possible.

"I'd love to fall asleep with you in my ass like this and find you that way when I woke up in the morning," she cooed. She was looking at us in the mirror as she said that, with what I thought was a twinkle in her eyes..

"All the other positions have you on top. They are all variants of the same sexual positions for vaginal sex. Are you ready to try them?" She said she would try them.

"Okay. I'm going to pull out of you and get on my back."

I did and rolled towards the center of the bed. I grabbed the tube of lubricant and added more to my cock before proceeding. The first position we tried was the reverse cowgirl but with me lined up to slide into her ass instead.

"It's going to feel a little weird for both you and me because of the angle. The head of my cock is going to rubbing the back surface of your rectum."

She slipped me in with no problem particularly sitting straight up. But as she leaned forward, it bent me in an unusual angle for when I was hard and erect. She told me that it would take some getting accustomed to.

"There's a great variant of this position that allows you to control the depth and pace of stroking that's a more natural angle. It can be tiring but you can always sit and rest in this position and then continue when you're ready. I had her unfold her legs from beside me so that she was in a crab-walk type position. She knew right away that she liked it. It was a better alignment and she could stroke me to various depths including a balls deep. She took to this position like a natural, just like her sister did.

I pointed to the mirrors to watch how her body bounced and responded with each stroke. She was getting intense rectal stimulation from this position like she had before. I propped up on my elbows behind Abby and told her that if her sister was here, I'd have her bring her lips to her pussy and clitoris. At that moment, I reached over her left leg and and brought my hand to her pubic area. My fingers found their mark and Abby was off to another orgasmic couple of minutes.

She recovered pretty quickly but I was getting much closer to cumming.

"The other variants are in the cowgirl position, normal and crab-walk position." Abby moved into position and slid down my cock in the cowgirl position. "Good angle, good depth and intensity control this way." I don't think Abby was paying any attention to what I was saying and was just bouncing up and down on me taking in the sensations.

"I like this position for the same reason I like it vaginally. I can see your body and facial expressions and we can see each other cum."

"You're getting ready to, aren't you?" she asked.

"Yes. I'm getting close."

I suggested that she unfold her legs into the crab-walk position. This bent me slight the wrong way but allowed the tip of my cock to rub along the inner facing wall of her rectum towards her bladder, vagina, and uterus. Although tight, her rectum didn't have the same "grip" as her vagina.

"What I love in this position is from here I can watch my cock slide in and out of your ass. I can watch you and touch you (reaching up and gently grabbing her right breast)." I was right on the edge of cumming and couple of more deep strokes would be all it would take to push me over the edge.

"And we can watch each other cumming just like this..."

I remember changing my pelvis angle and thrusting upward as my left hand slid down her right thigh and my thumb found he clitoris and and penetrated he vaginal opening. That sent her over her own edge as we shuddered to our mutual orgasms. Once she regained control, she folded her legs back to a more natural position and laid down on top of me, my cock still in her ass.

"Are you going to spend the rest of the night with me and sleep with me?" Abby asked.

"Yes, I am."

"That'll be nice," she said as she snuggled down on me.

A few minutes later, my cock slid out of her ass and my bladder was asking for relief. She was already asleep in my arms on top of me. I gently awakened her and told her that I needed to go to the bathroom. She let me up and, once again, I checked the hallway before walking down it to the bathroom. After emptying my bladder (it was pretty full from the enema), I took soap and water and washed my cock off. Although I might end up doing more anal sex with Abby, I wanted to be prepared if we went vaginal. No sense in causing a bacterial infection if it could be avoided.

Back down the hall I went to Abby's room. She was already dozing off again. I turned off all but one light in the room and that one had a dimmer which I turned down to low. I crawled into bed behind her and snuggled into the spoons position with her. It had been nearly four hours since we had started this sexual interlude and it was approaching 3 AM. I drifted off to sleep pressed lightly against her back, my arm draped over her.
