So far so very good, judging by the noises Helix was making and so Aidan gained a little more confidence in the act, pressing his tongue firmly against the other and rocking into him with his mouth. He licked and lavished, experimenting with the angle and intensity while keeping a close ear on Helix's reactions. From time to time he eased off, lightly tracing his tongue up and around, lapping at the others balls before sinking right back down to hungrily lavish him with his mouth and tongue.
After a while he felt safe enough in knowing how the dam work to push things a little further, moving back momentarily to take a new approach. He moved one hand over to press against the thin latex sheet on both sides of the others entrance, fingers spreading him out like he would a woman. He gave a few experimental licks to make sure it would stay in place before shifting up his free hand to the others hip, edging towards Helix's neglected erection and brushing his fingers up against it. With that he pressed against the other once more, licking him hard and pushing his tongue into him best he could - he didn't get very far but it'd no doubt feel pretty good either way.
Meanwhile he wrapped his fingers loosely around the others length, gently stroking it to add another sensation to the mix. He wasn't trying to get him off, right now he was just curious to see how far he had to go before Helix started asking for more and if he by some miracle managed to push him to climax with just this..? Well, all the better really.
