The clinic's dim lights cast an erotic glow as the twink, cheeks flushed, lies back, his slender frame trembling with anticipation. The granny, a wicked grin on her face, lubes up her fingers, teasing his tight, virgin hole, making him gasp. She leans in, her breath hot on his ear, "Ready for your first gay fuck, darling?" He nods, his cock throbbing, as she slips on a strap-on, ready to initiate him into the world of gay pleasure, one thrust at a time.
