It was summer, and the sweltering sun made them prefer the fresh air inside one of their houses, but right now the temperature was rising nonetheless.
They were at Kei's house, and while the two were playing a board game, Mrs. Tsukishima announced to the two teenagers that she would be going shopping for a few hours. The two said goodbye to the woman very naturally with a slow wave of their hands, staying near the living room window until they saw the car drive away and disappear around a corner. A few seconds of complicit silence passed before, with a movement of mutual understanding, they headed to the blond's room.
The room heated with their breathing, mingling on each other in desperate, hot kisses. Tadashi moved his mouth away from Kei's for a moment to plant wet kisses on his neck and occasionally bite his shoulders, making Kei gasp, holding onto the other's shirt as if his life depended on his boyfriend not letting go. In a swift movement, Tadashi threw them both onto the bed; he lay face up on it while Kei ended up sitting on his lap.
Kei leaned in eagerly, joining their lips again and savoring the aftertaste of his tongue, all while moving his hips in a circular motion that excited the other. He was hyperaware of how his sweat was making his shirt stick uncomfortably to his body. So when the other pulled away, needing air, he didn't need any more hesitation to quickly remove it. He leaned in close to Tadashi's ear and sighed, "Come on, sweetheart. Take 'em off," while continuing to make suggestive movements with his hips.
Tadashi complied, running his hands through his own shirt and then down his and Kei's pants. He ran his hands over his hips and slim waist, and licked his nipples. He licked his fingers and ran them over his ass, slowly opening it with a small cry. "Ahh! Tadashi!" Kei sighed.
It didn't take long, going from one to two and then three in less than two minutes, massaging his prostate, milking every second as he watched the precum drip from his erect cock. His back hunched back, his face turned to the ceiling, his eyes rolling back in his skull, and his tongue lolling slightly, saliva dripping down his chin. "Oh, God! Tadashi, hurry up and fuck me already!" He said, grabbing him by the shoulders.
"Calm down, Kei," he whispered as he pulled out his fingers. "Just breathe a little," and began to align his cock with his boyfriend's ass.
Patience went down the drain. Kei, as soon as he felt his boyfriend against his insides, lowered his hips with all his strength; he sighed in relief at finally feeling full. He lifted his hips and repeated the motion, whimpering as he brushed against his prostate in a pleasurable motion.
The sound of their wet bodies slapping against each other and their heavy breathing covered the sound of the front door or the footsteps in the hallway.
Desperation was tangible in their cyclical movements, making Kei see stars against his closed eyelids, enjoying the pressure of Tadashi's hands against his hips, helping him rise and fall.
The bedroom door opened. "Hey, Kei. Ma..."
"Oh, yes!! Oh my God, yes!! Tadashi, Tadashi, Tada...!!!" he screamed with a guttural sound as he came. His brain didn't process the other's words until moments after they were spoken. With a swift movement, he covered himself and Tadashi, simultaneously grabbing the pillow from under the other's head and throwing it in his brother's face. "Get out, idiot!"
Akiteru, feeling a mixture of shame, shock, disgust, and terror, slammed the door with far more force than necessary.
Their ragged, labored breathing was heavy in the air, their bodies going from heavenly to dirty, every drop their own fluids feeling gross. They sat there, ashamed and undignified, in silence until Kei spoke.
"...Do you want to make a suicide pact?"
"...Yes. Yes, that's fine with me."
