Riko
"Well it's not really a sleepover we go in his room all the time." Ako explained to me. I slipped off my shirt and bra, tossing them into a pile on the ground. "I know, I know, it's just much more polite than "breaking into his room in the middle of the night, climbing under the covers and sleeping with our little brother" plus that's a mouthful." Ako put on her pajama tops and bottoms "I bet other things are gonna be a mouthful." We were both very excited. Tonight was the night we were finally going to force Keita to make love to us. But Ako was ignorant to my plan. We both waltzed into the hall, but quickly began to tiptoe as we realized Keita's light was on. Everything was going according to plan for me. You see the morning before I had given him a sex tape I made of myself, and he quickly rejected it so I left it on the counter. But today it was gone. I had expected that much. We crouched and quickly batman maneuvered to his door over to his door. I told my sister I would check it out, so I went in first and quickly locked the door. And boy was she not happy about that.
Keita
I jumped up terrified from my studying, as my sister burst into the room. Riko waltzed right over to me as her twin was banging on the door behind her. She tried climbing onto my lap but I quickly pushed her off. "WHAT!?" . "Hello, Keita-chan." She said seductively, getting up on her knees and puckering her lips to kiss me. Her lips meet mine, and before I could stop her, she slips her tongue and forcibly explores every inch of my mouth. I refuse to kiss back and try to push her away, but she has an iron grip. Instead of reaching for my dick, she grabs my arm and forces it up her shirt. I grab her left breast and tweak her nipple releasing small moans from her. "Oh Keita-san." She moaned. Riko grabs my throbbing member and rubs it with great force. "Riko no we-" "No tonight I'm not holding back, we're going all the way." She pushes me back onto my bed, and pulls my shorts down. "What are you doing?" "Shut up." She said as she wraps her warm lips around my head and bobs up and down lusciously, her mouth contorting quite sexily . It felt so good I almost couldn't bear it. "Where did you learn to suck cock like that?" "I practice it on you while you sleep." She said. "WHAT?!" I screamed. "Calm down Keita." She continued sucking.
Riko
I had began touching myself halfway through the blowjob and near the end, I was on the verge of tears. I need him, now. I cried out and rolled over on my back. His eyes opened slowly. "Huh?" he said sleepily. I stared at him in awe "Were you asleep?" "No" he said embarrassed. I cried out again. He looked at me for a second "What?" he asked. His eyes widened "Sorry sis I'm not going to do you any good tonight" he gestured down to his now limp Keita Jr. "Shit" I said. "Damn, and I was looking forward to telling my classmates how tight you were" he said jokingly. They both got into bed and snuggled close to each other. "Good night, Keita." "Good night, Riko."
