Ezio groaned and tilted his head back onto the bed. Leonardo was hitting that perfect spot inside of him, the one that sent pleasure arcing through his body. He pulled the artist down for a kiss, wrapping his arms around Leonardo's head and holding him close. Leonardo's hands were clenched tight on his hips, pulling him to meet each brutal thrust.

"Nngh, there, Leonardo... haah..."

Ezio yelped as Leonardo's mouth clamped down on a nipple, back arching as he started to suck. He was falling apart, mind turning into mush under his lover's skilled ministrations. His hands clung desperately to Leonardo's back, nails digging into the skin. Ezio closed his eyes, relishing in the feeling of Leonardo's cock splitting him open, stretching him beyond his limits. There was a glorious ache in his backside and his cock was drooling over his stomach.

Leonardo pulled off the nipple with a gasp. "Ezio! I can use a helical crank!"

Ezio slapped his hand over his face. "Not- hn- now, Leonardo." He wrapped his legs around Leonardo's waist, pulling him in closer and pushing up into his cock. The heat in his gut was growing larger, and he was so close- Ezio let out a growl of frustration when Leonardo stopped.

"Just imagine, I could set the gears perpendicular to each other, then-" Leonardo started pulling out, still muttering.

The assassin flipped them over, slamming his hips back down onto Leonardo's with a moan. "You can go back to breaking the laws of science later, amore, but right now you're supposed to be breaking me." Ezio grabbed Leonardo's hands and pinned them above his head, leaning over him with a hungry grin. "Come on, fuck me, Leonardo."

Leonardo gave his lover an indulgent smile, planting his feet on the bed and thrusting up. "You're insatiable."

Ezio gave a noncommittal hum, leaning back and pinching his nipple again. It was still slick with Leonardo's spit, and he whined when Leonardo sat up and pulled the other into his mouth. His cock shifted inside Ezio, sending shivers up his spine and making him clench down. Leonardo grabbed Ezio's hips once again, lifting him up then dropping him.

The orgasm washed over Ezio like a tidal wave, the man shuddering and sighing at the wet warmth filling him as Leonardo also let go. He dropped onto his side on the bed, groaning at the feeling of Leonardo's cum dripping down his thighs. Leonardo climbed out of the bed, muttering to himself about this or that invention, and Ezio sighed, letting himself drift to sleep.
