Blaine almost stumbles in his haste to get his pants off and quickly gets rid of his underwear, too. When he stands there in all his naked glory he glances at Kurt, a questioning expression on his face. The meaning is clear. He wants to see Kurt loose the rest of his clothes.

But Kurt just smiles teasingly, adding a wink for good measure, and walks over to their bed where he proceeds to push the covers off and then lies down, leaning back against the pillows.

He looks at Blaine coyly and traces one finger along the waistband of his sweatpants, the other one coming up to circle his sensitive nipple. He sucks on his finger to get it wet before he continues to play with himself, pretending that its Blaines skilled tongue thats licking around the hard nub and his teeth gently biting the flesh, not himself pinching his fingers. 

Blaine, who is now stood at the foot of the bed, watching closely as his husband continues to tease himself, can stand it no longer and grasps his cock which is standing up proudly, already dripping with pre-come, and gives it a few strokes to relieve some of the pressure.

The sweatpants Kurts wearing still havent been taken off and Blaine longs to see Kurt completely naked at last. He wants to appreciate every single inch of his body, from his defined chest down to his strong legs. They have time and he intents to get the most out of it. Its been far too long since they didnt have to worry about someone walking in on them.  

Blaine crawls up onto the bed and hovers over Kurt, the muscles in his arms bulging as he holds himself up. He catches Kurt looking at his upper arms appreciatively and smirks down at him smugly. He knows that Kurt has this thing, that he gets off hard on how strong Blaine is, so strong that he can hold Kurt up and fuck him against the wall, seemingly without breaking a sweat. If his husband begs nicely enough, Blaine might even indulge him. 

But first things first. He tugs at Kurts pants and the little tease finally gives in and lifts his hips off the mattress so Blaine can pull his sweatpants off. He slowly drags them down, revealing jutting hipbones and more of his soft, creamy skin. The absence of underwear makes Blaine even hotter, he knew that Kurt planned this, but he planned  it. Blaine just hopes that he hasnt taken the liberty to stretch himself out, thats something he would very much like to do himself.    

The pants are finally completely off and tossed somewhere out of sight, Blaine doesnt really give a fuck where they landed, and he lets his eyes trail down the length of Kurts lithe body. His lovely cock is already hard and twitching against his belly in anticipation, his balls drawn up tight and when Kurt spreads his legs far enough to show off his hole, Blaine sees the small entrance clenching, thankfully still tight and unstretched. 

He grabs the back of Kurts thighs and pushes his legs towards his chest, making him expose himself even more to Blaine, making him become even more vulnerable. And oh, the hickey he put on Kurts inner thigh some time ago is still there and Blaine groans deep in his throat. The mark is fading and hed have to renew it, but its there, marking Kurt only for the both of them to know.

Kurt slings his arms around the back of his knees to stay in position and Blaine quickly grabs their lube before uncapping the bottle and squeezing a generous amount into his hand. He warms it up quickly and then uses two fingers to massage Kurts hole, loosening it up a bit before pushing both digits inside until his knuckles meet Kurts ass.

Kurt gasps in pain, even though Blaine knows he likes the stretch, loves it, and he wiggles his fingers a little, quickly finding Kurts prostate and making his gasps turn into ones of pleasure. 

"Another, please!" Kurt writhes on Blaines fingers buried deep inside him, clenching around the stretch. But its not enough, and if he wants Blaine to fuck him, then he needs to be stretched with at least three fingers, if not four.

Blaine obliges happily and adds another one and now Kurt starts to really feel it. His muscles clamp down hard around Blaines fingers, making it almost impossible for him to move the around inside and Blaine groans. Kurt will be so tight when he finally fucks inside him, Blaine can barely wait.

He hurries through the rest of the preparations and doesnt bother with a fourth finger. But Kurt likes it rough, so he isnt concerned. He slicks his aching cock up with plenty of lube and then pushes inside slowly, keeping his pace deliberately gentle so Kurt can adjust to the size of him. When hes finally buried to the hilt, his balls pressing against Kurts ass cheeks, he stills and gives himself some time to get used to the almost unbearable tightness surrounding his dick. 

After a long minute, Kurt squeezes his muscles around him, prompting him to move. Blaine pulls almost all the way out before snapping his hips forward harshly, hitting Kurts prostate and making him cry out in pleasure. He keeps his pace slow but anything but gentle, repeatedly hitting his husbands prostate with his cock and making him scream.

His arms get tired after some time and he leans down over Kurt, pressing his legs further into his chest which in turn makes it possible for him to penetrate deeper. He loves how flexible his husband is, its a huge turn on for him, and he also loves to exploit in it.

They meet in a desperate kiss as Blaine begins to thrust faster into him as Kurts screams rise in volume and pitch.

Which is the exact reason why they dont hear the key jiggling in the lock downstairs, the door opening accompanied by the creak that it does when its opened about halfway, and the horrified and embarrassed gasp their daughter emits when she figures out what shes walked in on.
