He's not.

Dex's expression suddenly becomes very anxious. “I uh... I think I need to practice more,” he seems to expect you'll be upset. “But I wanna suck you,” he reaches for your cock, bringing it back to his mouth.

This is really not what you were expecting from someone trying to make up for the worst date you've ever had... but it's what you're going to get. You might as well enjoy it. You sigh and say, “Yeah, that's fine...”

You hold the back of Dex's head, again, but a bit more firmly as you thrust back into his mouth. He gags a little at the ****, then quickly figures out that he can control your cock a bit by using his hand to stroke you in time with his sucking.

Dex uses his free hand to start jerking himself in sync with you moving the vibrator inside him. At least it's a good view, watching his defined abs expand and contract as he rolls his hips back and forth between thrusting into his hand and pushing himself back onto the dildo.

You don't expect Dex will last long, so you let yourself give into the feeling deep in your stomach and moving towards your cock. Dex has started using his tongue, stroking it along the underside of your shaft, and his hand at the base of your cock is doing pretty well. It isn't too long before you start to feel your ogasm start to build. Dex is apparently ahead of you, as his hips are moving more frantically. When you feel his ass open up more as his orgasm begins, and you thrust the vibrator in and out of his hole as fast as you can. He winces and gasps, losing suction around your cock.

You quickly replace Dex's hand with yours, and luckily your cock is still wet enough with his saliva for some fast stroking. Dex starts loudly groaning just before the first spurt of cum shoots out of his the head of his penis and lands on his cheek and chin. His cumming expression and the splatter of white semen on his face is enough to set you off, and you let your orgasm burn up from the base of your cock and out. Dex continues to ejaculate, creating a trale of white cum from his face, down over his chest, and forming a pool on his lower abs. The first of yours shoots right into his open mouth, like he was waiting for it. You purposely make sure to unload some around his mouth as he swallows the first couple of spurts that landed on his tongue.

You orgasm is fading, but you still want to paint him more with your semen. You shift and make sure to deposit the last couple small spurts on his chest, mixing it with his own cum. Dex makes a good smutty canvas, with his and your cum spattering his dark skin from his face down the length of his body to his spent cock.

He opens his eyes and smiles a tired smile up at you. “You missed some,” you smile back and use your still-hard shaft to push some of his and your cum from his cheek and lips into his mouth. Dex accepts the gift, licking the mix off of the head of your dick. He looks adorably bashful as he swallows.

He lifts his head and looks down his body. “Wow, I'm a mess...”

“Nah, you're a Pollack painting,” you joke and grab some tissues from his bedside table and drop them on his stomach for him to wipe himself off with. You turn your attention to the vibrator still in his ass. “Coming out...” he braces, and you slide the toy out of his ass. He winces a little, but you rub his loose hole lightly with two fingers. “There, y'go... you seemed to like that. You should keep practicing, and show me how well you're doing, soon.” You grab a new tissue and wipe off his cheek as a token sign of affection.

“We'll see, Mister,” he replies with a coy grin.

Without ceremony, you climb into bed next to Dex. He insists on a long deep kiss, then he lets you roll him to his side so you can big spoon him. Your penis is still half hard, and you make sure to fit it between his butt cheeks. “He likes it there.” you murmur into Dex's ear who giggles quietly.

You really wish you'd gotten to fuck him, tonight. There's still a chance, but you should probably work on being more affectionate if you see him again. You drift off to sleep, occasionally stirring to hump Dex's backside.
