Innocently beginning with a playful tickle fight, Seth finds himself increasingly aroused by his friend's lithe body. At my request, he turns around, revealing his pert, smooth ass. I can't resist running my hands over his cheeks, feeling him tense and then relax into my touch. His breath hitches as I slip a finger between his cheeks, teasing his tight hole. Seth's voice is barely above a whisper, "I've never done this before," but his body betrays his inexperience, pressing back against my exploring digit.
