Alexander was flushed and trembling as he watched them, his hand between his legs and his eyes locked onto Isabelle's every move, entranced.
Although he seemed still too conflicted to get close, the water splashed audibly with how quickly and...eagerly he stroked himself watching her.
She turned to look at him, her eyes half-lidded with lust as she crooked a finger at him, inviting him to join. "Alexander...come to me."
The redhead bit his lip and hesitantly slid over to her, his erection jutting proudly from between his legs. "...I'm here..." He whispered breathlessly, his gaze fixed hungrily on her tits as he waited for permission.
She smirked at him, loving the way his eyes flickered with barely suppressed need. "It's alright, sweetheart..." She purred. "Go ahead. Have a taste."
Alex shivered at the word and gently cupped her breast in one hand, his thumb circling slowly over her hardened nipple. "Yes...of course, Isabelle." He breathed.
