His hands shook a little as he unbuttoned Isaac’s pants, tugging them down over his hips. He didn’t know why; that part was familiar. He didn’t even know why he’d /asked/. Isaac wasn’t different. Summer closed his eyes, groping, wrapping his palm around Isaac’s cock. He tugged gently, and it was like he flashed back to the transformation, as magic probed within him, pulling, with every stroke drawing his cock longer, thicker, literally out of his body, reshaping his flesh.
He groaned, knees trembling, feeling the way his blood pulsed as Isaac caressed him. The sensitivity was incredible. He could watch as he swelled in Isaac’s hands, as pre-cum beaded at the tip, and his hand spasmed around Isaac’s length.
He keened the instant skin met skin, his hips jerking forward with increasing patience as his own grip tightened around Summer’s cock. He trembled and arched up, free hand gripping at the boy’s much shorter hair, the fiery locks sliding through his fingers, breath hitching as the arousal increased in the air.
“N-now you know exactly how I feel — not many girls can say that, huh?” He attempted to interject some humour into the conversation, but he could barely focus on anything other than their bodies rutting against each other’s hand, the friction truly delicious.
“Some of it, anyway,” Summer gasped. “Y-you going to teach me all of it?” He wrapped his fingers more tightly around Isaac’s tip, smearing the clear liquid around. Abruptly, he knew he wasn’t going to be able to last the way he could when he was she. “Isaac, I — ” And he came hard, shuddering in Isaac’s grip.
