He grabs the back of Caleb's head, fingers tight in his hair as his mouth covers a firm nipple and sucks hard. The scrape of teeth makes slick walls squeeze tight around the cock driving into him; it makes his back arch like he's trying to present himself more.

"Caleb--" Yussa's voice is tight and thighs and arms tense as he tries to meet every hard thrust, tries to keep pace with Caleb's renewed urgency. He isn't particularly strong but that doesn't stop him from holding on to his lover. His hand drops away from the rock in favor of pushing between them so he can stroke his fingers over and around his clit. Breathless praise falls from his lips - little of it actually in a language they have in common - but surely his meaning is clear.

He bows his head, lips grazing Caleb's temple. Yussa has never invited Caleb to leave marks on him before - nothing that wouldn't fade within an hour or so, anyway. But now he finds himself wanting the harder sucks and drag of his teeth, rough counterpoints to his mounting pleasure.

Yussa blunt nails drag against the back of Caleb's neck as he tries to--assist in Caleb's efforts. Tension rolls through him as that familiar, urgent feeling builds. He'll come again, certain he has it in him if Caleb keeps fucking him like that.
