Eventually she built up a steady pace. She used her tongue to lick the underside as she slurped up and down on her boy's beautiful member. Sometimes she'd stick her tongue out and lick his pendulous nuts. Precum seeped from her son's cock and she savored the flavor. Kierston unbuttoned her jeans. The heady masculine taste of her own son was driving her crazy. She couldn't help herself. As she continued slurping down as much of her son's length as she could manage, she jammed her hand into her panties. Her underwear were a soaking mess. Her clitoris was stiff and engorged and she rolled it gently between her fingers. Pleasure shot through her body. She let out a moan. The vibrations ran through the length of Kain's cock and he moaned in turn.
