Blaine could feel Kurts come starting to slide out of his ass and down to his balls before he felt something else. It was warm and wet and tracing patterns across his hole. He stiffened when realization hit him. That was Kurts tongue and he was gathering up his own come.

He heard the unmistakable sound of Kurt swallowing behind him and started to turn his head to look at him incredulously, but Kurt went right back to it, leaning down and licking at his balls before dragging his tongue up until he reached his gaping hole where more come was starting to slide out.

Theyd never done anything like this before and Blaine didnt know whether he liked it or not. It was a little weird, but at the same time it was unbelievably hot, Kurt eating his own come out of Blaines ass. He pushed his hips back towards Kurts face and spread his legs wider to make the angle better for Kurt to work with.

Hed never thought he could enjoy this. He would have expected to feel more than a little uncomfortable and surprised himself with how much he really didnt mind. In fact, he didnt want Kurt to ever stop what he was doing with his tongue and his cock seemed to agree wholeheartedly if the way it was twitching, doing its best to get hard once more was any indication.

Kurt moaned at the first taste of himself mixed with the unique but not bad taste of Blaine. He didnt know why he was doing this now, all he knew that hed fantasized about it for some time now and he made the decision on a whim. The sight of Blaines fucked out ass, his hole stretched out and red, a stark contrast to his own come was too good to pass up and before he could try and stop himself, hed leaned down and licked up the come that was starting to trail down Blaines ass.

He grasped at Blaines cheeks, another thing he loved about his boyfriend, and separated the two halves before diving in deeper, pushing his tongue as far in as it would go and swallowing his own load. He was spurred on by Blaines moans of pleasure and the way he was grinding back, trying to get his tongue in deeper and if that wasnt hot he didnt know what was. 

He reached around Blaine and took his regained erection in his hand and started stroking in time with the thrusts of his tongue and Blaines moans raised in volume and pitch, doing nothing to mask his desperation. 

His own cock had started to take notice as well and was standing proudly against his stomach and he quickly inserted a finger in Blaines ass alongside his tongue, then another and finally a third just to torture him a little and then grabbed the lube and coated his dick generously. 

With his dick in his hand, he shuffled around behind Blaine, whod arched his back to expose himself even more in obvious anticipation of what was to come, and after he got into position, he guided his cock to Blaines rim, tracing the stretched muscle and taking delight in the way Blaine started to whine and grind back against him to get his cock to slip in.

Giving his boyfriend what he needed, he pushed in slowly and moaned almost embarrassingly loudly when there was no resistance at all, Blaines body already adjusted to the thick girth of him and taking him with no problems. He started to move his hips slowly when he was all the way in and Blaines insides were still so wet with his come and spit, so warm and snug around him that Kurt just wanted to stay inside Blaines ass forever. He knew that wasnt possible, sadly, and he savored every second of it, starting out with slow and deep thrusts and then moved with increasing speed until he was back to slamming into Blaine, practically fucking the moans and groans out of him.

It didnt take long at all for Blaine to get close which was an ultimate boost to his ego, knowing that hed enjoyed the rimming so much that he could come again so soon. He just doubled his efforts and moved his hips faster, tightened his grip around Blaines weeping erection and did his best to stroke him in time with his thrusts.

Blaine started making little uh uh sounds, so desperate and unable to eloquently voice his pleasure, and Kurt changed the angle so he was hitting Blaines prostate with every shove inside. It barely took any time for Blaine to get there after that and he came so hard that he passed out. 

Kurt slipped his dick out so as to not hurt him due to oversensitivity and sat on his haunches behind Blaine, desperately tugging on his cock, squeezing his balls with his free hand and then reached around to massage his own hole. Thats what did it for him, his balls drawing up tight and his dick jerking in his hand. With a loud gasp, he came across Blaines ass cheeks and over his hole, the come catching on his rim and sliding inside and oh god, if that wasnt the hottest thing ever.

After he came down from his high, exhaustion came fast and he did a halfassed job at cleaning himself up in the bathroom before coming back and doing a very thorough job of cleaning Blaine. With his tongue, mind you.
