He advances the relationship

John goes up to his mom. And hugs her from behind. " Hi sweetheart you having fun hugging your mom?" John shakes his head. " Maybe you can help mommy with something else?" She turns around and kisses him on the mouth. And whisper to him. " Make me feel good." They go back to kissing all of a sudden his cock begins to grow longer. Eventually it goes out of the crotch hole. "Oh my." She grabs it "Do you want some mouth resuscitation?" He shakes his head. "Alright." Gets down on her knees and begins to lick his shaft. "Mmmmmm it's tasty baby." He then says "Mommy please blow into it." She looks at him confused, but obliged. She puts it in her mouth and begins blowing.
