Greg looked up, checking that those shivers and whimpers were not from fear. Satisfied, he tugged leaned and tugged another towel down, throwing it over Theo partially. His look was wolfish, hungry and he ran a hand across Theo and said, "Now to check if you are clean.."
Greg's hand found Theo's groin and this time he began to fondle him even as Greg bent down to lick Theo's hip, moving towards Theo's groin. His hand held Theo even as his mouth found the shaft,kissing the tip at first as he began to alternate between licking the length and then sucking on it. Greg's lips pursued around the growing hardness, encouraged by the reaction and he lift Theo so that he could mouth each tactical, sucking on each before moving back to Theo's partial erection.
Greg moaned with pleasure at the tongue bath he was giving Theo. All of it was definitely having an effect on himself, awakening his own want to fuck Theo silly.
