Senku woke up to a uncomfortable feeling, he was hot, sweating, and he felt an unpleasent feeling between his legs. He was horny. And he needed relief. Fast. He looked to his side and saw Gen sleeping peacfully, Senku bit his bottom lip thinking if it was right to wake Gen up just so he can pound Senku's ass. Senku sighed and looked at the clock, it was way past midnight, so Gen won't wake up soon. The scientist decided to wait, he layed on his back and closed his eyes, hoping to drift back to sleep. Unfortunately, his erection didn't go down at all, he looked at Gen again, his sleeping face was beautiful, and Senku felt bad for what was he about to do. He sat up on the bed and turned his whole body to Gen, his eyes wandered to Gen's leg that was close to Senku. Senku exhaled and bit his lip, he quietly crawled over, and gently sat on Gen's thigh, the scientist was nervous but he needed it, he gulped and gave a hesitant thrust to test the waters, Gen didn't wake up. Senku gulped again, and began humping Gen's tigh, his shorts were rubbing him just right, Senku let out a tiny breathy moan as his thrusts quicken. After what felt like hours Senku came with a moan, it felt amazing, but not enough, he wanted more, but he couldn't wake up Gen. Senku was catching his breath and he looked at Gen, to his horror Gen was waking up, Senku froze, his body not moving. Gen finally opened his eyes and saw Senku, out of breath, on his thigh. Gen sighed and yawned, then smirked.
-"Couldn't get enough of me love~?"- Gen teased in his low voice. God Senku could get off to Gen's voice when he wakes up.
Senku nodded and bit his lip again.
-"G-Gen...I...Need you...now...please...."-Senku begged, his hips lightly grinding Gen's leg.
Gen sighed and rolled on his side, making Senku lose his balance on Gen's thigh making him fall side ways. Senku looked confused and he crawled closer to Gen, poking his shoulder with a pout, wanting an answer.
-"I'm tired Senku. We'll do it in the morning alright?"-Gen said not looking at Senku. It was not entirely true. Gen could get up and fuck Senku. He just wanted to see how long the genius can wait.
Senku grumbled under his breath, but layed down trying to sleep.
______In the morning______
Gen slowly stirred, and he felt a weight on his stomach. He opened his eyes, and to his suprise Senku was sitting on him, looking at him with those beautifull ruby eyes. Senku tillted his head, a small pout on his lips as his hips started moving slightly.
-"Now?"- He asked sweetly, clearly impatient
Gen chuckled to himself. Well. Guess his morning will be good after all.
