Riley grinned wider, that wicked sparkle in his eyes as he looked down at Kota pinned beneath him. "Good boy, Kota. Stay right there. We're not done with you yet." He glanced over at Dennis, who was still kneeling beside them, glossy lips shiny with leftover cum and eyes hungry.
"Dennis, you heard me. Be extra good for our stud. Take those jeans off and show him how bad you want it. Big bro's gonna coach you the whole way."
Dennis nodded fast, cheeks flushed under all that heavy makeup, fingers already fumbling with the button on his tan and blue booty jeans. He shoved them down his thighs in one eager motion, kicking them off along with his underwear until he was naked from the waist down, pink crop top still riding high on his slim torso. His ass bounced free, just as massive and heart-shaped as Riley's, cheeks jiggling with the movement. Dennis climbed up, straddling Kota's hips in cowgirl position, hands braced on Kota's chest as he lined himself up.
Riley clicked his tongue immediately, shaking his head. "Wrong way, little bro. Turn around. Reverse cowgirl. We wanna see that nice ass of yours clap while you ride. Kota deserves the view."
Dennis blushed deeper but obeyed, spinning around so his back faced Kota. That monumental ass hovered right above Kota's cock, cheeks spreading slightly as he reached back to guide the tip. He tried to sink down, but the moment the head pressed against his hole it was way too tight and dry. Dennis winced hard, a sharp hiss escaping his glossy lips. "Ow… it hurts… too big…"
Riley was already moving, grabbing a big bottle of lube from under the bed like he had it ready for exactly this. "Hold on, baby. Big bro's got you." He squeezed out a huge amount, lathering it all over Dennis's ass and Kota's cock until everything glistened. Then he knelt behind his brother, two fingers sliding in easy at first, then three, pumping deep and stretching him open. Dennis started moaning in a mix of pain and pleasure, hips rocking back onto Riley's hand. "Ahh… Riley… it burns but… feels good too…"
Riley worked him open carefully, scissoring and curling until Dennis was whimpering steadily. He added a fourth finger for just a few seconds, pushing deep, and Dennis screamed, body tensing. "Too much! Too much, Riley!"
Riley pulled his fingers out gently, patting Dennis's jiggling cheek. "Shhh, you did so good. Such a brave boy. Big bro's proud. Breathe for me. You're all nice and open now. Kota's gonna feel perfect." He cheered him up with soft kisses on Dennis's shoulder and a quick squeeze of his hip. "Go on. Sit on it slow. You got this."
Dennis nodded, still breathing hard, and lowered himself again. This time the lubed head slipped right in, stretching him wide. He sank down inch by inch until he was fully seated, ass flush against Kota's hips. The second he bottomed out Dennis came immediately, untouched, his small cock spurting across Kota's chest in thick white ropes. "Oh god… I'm cumming…"
Riley scolded him lightly, voice teasing but firm. "Quickshot already? Bad boy. We just started." He scooped up the warm cum from Kota's chest with two fingers and brought them to Dennis's mouth. "Eat it like a good boy. All of it. Show Kota how grateful you are."
Dennis flushed bright red, super flustered, but opened his mouth and sucked Riley's fingers clean, swallowing with a shy little moan. Riley grinned and gave his brother's ass a playful smack. "That's it. Now bounce."
Dennis started moving, lifting up and dropping back down. The first bounce made him cum again, prostate hammered perfectly by Kota's thick length, another spurt hitting Kota's shirt. By the second bounce he was moaning loud, body shaking, ass clapping wetly against Kota's thighs. The third bounce had him gasping, hands gripping Kota's legs for support as another orgasm ripped through him. On the fourth bounce his hips stuttered, thighs trembling so hard he could barely move.
"I.. cant keep going"
