Work Text:
Ever since Aoba Johsai lost nationals, Oikawa started starving himself. Iwaizumi quickly found out and immediately got him help. After exiting the mental hospital he was in, Iwaizumi promised he would help him get back to the way he used to be so he could achieve his dream and play in the Arginatian volleyball team. Oikawa was in a rough spot, he would do really good, then spiral a little bit, but not far, as Iwaizumi was there to catch him if he went too far. He could only eat one full meal a day. Iwaizumi had a wild idea one day on their bed cuddling. “Hey, Oikawa you trust me right. I have a weird idea that might help you.” Iwaizumi said, breaking the comfortable silence. “Sure, but I doubt it will work, I have been in this slump for so long, just going back and forth.” Oikawa mumbled. “What do you need me to do?” Oikawa questioned, sitting up, facing Iwaizumi. Iwaizumi got off the bed dragging Oikawa off with him. Stripping both their clothes off. Oikawa just looked at him with his eyebrow raised, questioning him. Iwaizumi manhandled Oikawa so he was straddling Iwaizumi’s waist with his back facing him. Iwaizumi pushed Oikawa’s lower back down, making him face his cock. “Suck” was all he said before licking a stripe on Oikawa’s entrance. Oikawa was quick to go to work licking the tip, making Iwaizumi groan. Iwaizumi shoved his head down, making Oikawa gag a little, but he got used to it very quickly. Oikawa hallowed his cheeks making more room for Iwaizumi. Iwaizumi’s tongue pierced Oikawa’s entrance making him moan on his cock, sending vibratiors up it. Oikawa quickly bobbed his head, the more Iwaizumi thrust his tongue in him. Oikawa started to rock back on Iwaizumi’s tongue, also creating friction on his cock trapped in between his abdomen and Iwaizumi’s chest. Iwaizumi also started thrusted his hips making his cock hit Oikawa’s throat. Iwaizumi, too distracted with how Oikawa is deepthroating his cock stops moving his tongue, which is right on Oikawa’s prostate. The constant pressure on his prostate makes Oikawa bob his head faster, gagging, but still going. Iwaizumi can tell how close Oikawa is with how he is clenching around his tongue. Iwaizumi is close but not as close as Oikawa, so when he can tell Oikawa is on the edge, Iwaizumi snakes his hand under Oikawa, effectively stopping him from coming. Oikawa all but whines, making Iwaizumi groan. Iwaizuimi is back to moving his tongue slowly as he can tell he is still a little sensitive from his denied orgasm. Oikawa starts to bob his head slowly but deep and when he goes up he makes sure to pay extra attention to the tip knowing Iwaizumi is sensitive there. He can tell Oikawa is close again and so is he, so he slips a finger along with his tongue, hitting his prostate with both. Oikawa comes as Iwaizumi puts a second finger in. His moans make Iwaizumi follow shortly after. As Iwaizumi is too far down Oikawa’s throat he is forced to swallow of Iwaizumi. After both rode out their high, Iwaizumi gently detaches himself from Oikawa, setting him on the bed to recover from his orgasm as he technically had two. He gets something out of their “toy” box, in the closet. He quickly returns to Oikawa, sticking three fingers in him, using his leftover saliva as lube. Once he makes sure Oikawa is stretched out enough he places the vibrator he got inside of him, turning it on to the lowest level. “Knees,” Iwaizumi orders, Oikawa following immediately. Oikawa quickly took Iwaizumi back into his mouth, this time he bobbed short and fast trying to match his thrust to the vibrator. Without slipping out of OIkawa’s mouth, Iwaizumi moves them so he can lean against the headboard, also using it as leverage to thrust up in Oikawa’s mouth, hitting the back of his throat. Oikawa’s gag reflex is usually not existent unless it has been awhile since they did anything. Oikawa was nice and warm around his cock. He turned up the viberator, Oikawa wasn’t even moving his head anymore as Iwaizumi was thrusting in his mouth faster then Oikawa could even move his head probably. He could tell Oikawa was close with the moans coming out of him. He was so close too, how could he not be, the sinful image of Oikawa on his knees, just for him, plus the sounds he was making and how they made his cock twitch. He spilled in his mouth the same Oikawa did on the sheets, not even having the chance to touch himself. Iwaizumi turned down the vibration letting Oikawa ride his high the whole way as he deserved it as the past months have been very hard on him. He turned it off completely when his moans turned into whines of oversensitivity. He fell asleep as soon as his high was done. He took out as gently as possible knowing how sensitive Oikawa must be. He laid him down wiping his stomach, he would wash the sheets later, right now he wanted to cuddle Oikawa. His plan was to do this as often as necessary as Oikawa needed the extra calories, he also planned to do most of the work so Oikawa wouldn’t lose his precious energy doing it. He was overly proud of his boyfriend. He quickly settled down next to his boyfriend so they could cuddle.
