Ty found he could only look at that big hard dark cock for a little longer before the urge to suck on it became unbearable. He quickly hit on a way to rationalise it- sure, he'd always considered himself to be straight, but just as long he'd considered himself to be attracted to Eileen. So even though she was a man now, naturally he'd still feel attracted to him.
Eileen's eyes widened as Ty moved to his cock and encircled it with his mouth. "Ty, wh-aaahhnn..." he groaned deeply as the teenage boy started to suck on his shaft. Even if the nerves felt more spread out than her clit's had, it felt just as good if not moreso to Eileen to have his cock sucked as it had to have her pussy eaten. The unfamiliar hormones made it more intense too- it felt so weird for his body to be trying to release something rather than receive it, so to speak. Even more striking was how strong he felt- like he could just force his cock against Ty's throat with primal, animal force, and while his motions were restrained, there was a forcefulness to them that was nothing like he'd been able to feel as a woman.
Meanwhile, Ty was surprised how enjoyable sucking a penis felt. The strong musky scent and taste was intoxicating, as was how big and firm it felt in his mouth, particularly with Eileen thrusting at him. Occasionally a salty-tasting liquid would leak onto Ty's tongue, and it spurred him to continue, Ty surprising himself with how much he liked it.
At last, Eileen couldn't hold back, and he moaned deeply as he ejaculated for the first time, his warm load shooting down Ty's throat as he held the boy close and simply came in his mouth. Ty swallowed most of it breathlessly, but enough remained that it rested upon Eileen's shaft as Ty took his mouth away. The two of them looked at each other in amazement at the intensely pleasurable homosexual behaviour they'd just partaken in.
Ty moved up to Eileen and smiled. "Lemme just fix something," he grinned, and wished for Eileen to be ready to fuck again. The Brazilian man smiled as he felt his arousal returning and kissed Ty passionately, and as they made out they wondered what to do next...
