Eric might not have been good at English but he knew what to say to make anyone moan, especially someone who seemed relatively inexperienced. And it worked, and, even better, it gave Gabe some more freedom and a new experience. Eric wasn't going to gag, wasn't going to choke, wasn't going to need to breathe, so Gabe could do whatever he wanted to his mouth and Eric wouldn't complain. Rather, he would enjoy the ride, working to synchronize his movements with Gabe's, chasing the tension he could feel starting to build within his human friend.
His movements grew more intense, heated, and he gripped Gabe's hips, trying to urge him up harder and deeper into his mouth. And, when, finally, he felt Gabe's release hit the back of his throat, Eric groaned around him as he swallowed, carrying him through the aftershocks of his orgasm before lifting his head.
Sliding up Gabe's body, he remembered that humans sometimes liked modesty and reached for the blanket, pulling it over both of them as he fit himself against Gabe's side. Nuzzling against his cheek, Eric trilled happily against Gabe's neck, the only inhuman sound Gabe had heard him make, and one that wasn't as ugly as Deep Ocean Mermish. "Is good?" He asked in a quiet murmur against Gabe's skin, staying close, holding him close.
