We did get some sleep that night, though the number of hours we were having sex and the number of hours we were sleeping were probably pretty close to equal. When I did sleep, it was solidly and I was still pretty well out when she slipped under the covers early in the morning and wrapped her lips around my cock but it didn't take much of her skillful cocksucking before I was fully awake. It was still too dark to see her even if I'd thrown back the covers so I just lay there enjoying the pleasure provided by her mouth.
The way she had crawled under the covers, her ass was nearby so I reached over to caress it as her mouth moved up and down my stiff cock. I probably could have caressed her pussy, which I assumed was dripping wet, but decided to just focus on the pleasure I was feeling then she could do the same once she was done with me. Because she was such a talented cocksucker, it wasn't going to be long before we were switching roles, though I anticipated thoroughly enjoying eating her pussy again. For the moment, though, I just caressed her ass while savoring the feeling of her hot mouth sliding up and down my rigid tool. I didn't try to hold back my orgasm and it didn't appear that she was trying to draw things out either; we did still have to get to work that morning, after all.
The closer I got to cumming, the more my cock was swelling but that didn't impact her cocksucking and she just continued to inhale my tool. She was gently pumping the base while sliding her lips down as far as she could manage, which had my orgasm building with a high level of pleasure. It was silent in that hotel room aside from my occasional moan and a random slurping until I started spewing into her mouth with a prolonged groan. She continued to suck me off while swallowing my load as I repeatedly spurted into her mouth. Only once I was fully spent did she let my cock fall from her mouth and crawl back out from under the covers.
"Whew!" she exclaimed, "It was getting warm under there."
"Well let me reward your efforts," I suggested, reaching for her.
"We're going to be late for work if we don't get moving," she replied, getting off of the bed, "so you'll have to join me in the shower if you want to continue."
I dragged my ass out of bed and followed her to the bathroom where she got the water going then stepped into the shower and wet herself down first. It was a big, glass-walled shower with no tub so I watched her for a moment through the glass before I stepped in and took my turn while she got the body wash. While I thoroughly washed her tits, she managed to raise my cock from flaccid to half-mast. Since we had to go to work, we actually needed to make sure we were thoroughly clean, not just our favorite of each other's parts. When I was working on getting her legs clean and her trim, dark blond bush was right there in front of my face, I couldn't resist cleaning her slit with my tongue. She didn't try to stop me, instead holding onto my head and pressing her pussy toward my face. I slurped at her slit and her clit but didn't slip a finger into her since my hands were full of soapy lather. Instead, I was lathering up her ass cheeks while eating her pussy, eventually also lathering up her ass crack.
She was moaning continuously, the sound echoing through the bathroom, so she was obviously building toward another orgasm. When my soapy finger between her ass cheeks passed over her asshole, she seemed to moan a little louder but definitely didn't give any indication that I should stop. I didn't give it much thought, really, and just ended up slipping my soapy finger into her ass without any difficulty. Just a moment later, she cried out and her body started shaking as she suddenly started cumming. I continued to lick and suck her clit while sliding my finger in and out of her asshole a few times since she didn't seem to object. It appeared to be another of her typically long and intensely pleasurable orgasms so I kept up what I was doing until she went still and silent. After slipping my finger gently out of her asshole, I stood and she immediately grabbed me and jammed her tongue in my mouth, obviously even more fired up now.
"I want to feel this in my ass now," she said, gripping my now rigid cock after we'd made out for a moment.
"As you wish," I replied, genuinely caught by surprise despite the fact that my finger had just been embedded in her ass. She grabbed the body wash and, after she thoroughly lathered up my cock again, she turned so that I could thoroughly lather her ass crack. Once she was ready, she braced herself against the shower wall as I lined up my cockhead with her asshole. With a slight push, I slid easily into her as she let out a moan. Holding her waist, I slowly slid my cock in and out of her ass, relishing the pleasure I was feeling as I did so. I didn't have to wonder whether it was also pleasurable for her because it probably wasn't two minutes after my cock slipped into her ass before she cried out and started shaking. She made no indication for me to stop so I continued to fuck her ass while I slipped my hands up to cup her tits. I hadn't even considered, despite all of the highly satisfying sexual activity that had already occurred, that I might be fucking her ass at some point. I was pretty psyched not only about the opportunity but also that she was so into it. When she had another orgasm not long after the first, it was becoming pretty clear why she was so into it.
