Hide, command, and observe.

You bring the ring up to your mouth and whisper your command, "Voice your thoughts by talking to yourself." You tip-toe around behind your mother before rolling your eyes and bringing the ring up again, "You don't see or hear me until I say hello to you." You slip the ring on and feel it vibrate.

Your mother immediately starts talking to the tv, "Why do they always cast this guy, he can't act worth a damn, and he always gets put with such good actress, that's a ridiculous double standard, I wonder what I'm going to make for dinner-"

You snicker, slipping onto the other end of the couch carefully. As your mom continues rapid fire voicing as many of her thoughts as she can and still draw breath, you concentrate on the coffee table in front of her. Your hard cock pops out of the table like whack-a-mole and your mother squeaks, lifting her legs, "Omigod! It's back! You're back! What the hell are you?! I must be hallucinating, why am I hallucinating, I must have eaten somethin-"

You roll your eyes and squeeze the ring, "speak normally, summarize your thoughts as though you were having a normal conversation." It vibrates and your mom takes a moment to get her breath back before continuing more normally, eyes fixated on your cock.

"I just can't stop looking at you... why are you so... attractive? So hot... it's just a cock, why am I getting so worked up over a disembodied cock? I have one of those in my dresser." You snort, trying not to shake the couch with your mirth. Your mother doesn't notice, slipping off the couch to kneel on the carpet, still alternating between talking to herself and addressing your junk, "You're such a nicely shaped cock, not even circumcised." You cough self consciously, slightly weirded out by her directness, nominally surprised she counted that as a positive.

"Just like John..." You gawk at your mother, hard cock pulsing in front of her. She shivers, "God that's so wrong, I'm so sick. I shouldn't be thinking about John when I'm looking at a delicious looking cock... I shouldn't even be looking at this cock. Why are you here? Why do I feel so... drawn to you?" Her hand slipped up, seemingly of its own accord, to wrap around the middle of your length. She moaned, "Mmm God, you're so hot... so soft and dry..." Her hand squeezes and begins to rise and fall, jerking your length slowly. Her head dips in closer and her lips part lustfully, "Poor baby, let me help you with that." She sticks her tongue out, straining to touch your tip but not moving closer. You watch, entranced, as a long string of drool collects on her tongue and begins dripping onto the head of your cock. You shudder as it rapidly cools, sliding down to meet her gently moving hand.

"Let me taste you baby, I need to taste you..." You're not doing anything to stop her, she's teasing herself more than you would have. She sinks down till her eyes are level with your relaxed scrotum, laid out on the edge of the table, "Please, I need it... you smell so good..." Her mouth opens and closes fitfully, her massaging grip tightens, and she quivers just an inch from your balls. God, at this rate you'd blow your load before her lips even touched you! Fuck woman! You would have grabbed her head and thrust your cock in if it wasn't disembodied right now. On some level you're thankful: paradoxically this was too hot to ruin with lust.

Whatever forces were fighting each other for control over your mother finally resolve their issues and she closes the distance, planting a wet kiss at the base of your cock between your balls. Your nails dig into your thighs, trying to distract you from how close you were from just watching your mother admire your dick. She groans loudly, her whole body shivering as your previous compulsion to be aroused by your taste kicks into effect. The kiss goes on and her tongue slips out, playing with the semi-loose skin above your testicles. Her lips form a seal and her cheeks hollow out, pulling in the wrinkled skin and tightening the remainder over your over-sensitive balls. You moan together as her tongue goes to town on your sack, the suction increasing until first one then the second nut slipped into her mouth.

You were in heaven. Your mother suckled on your balls so passionately you wonder if this is her fetish. Either that or the ring came with some kind of blowjob-skill magnifier. At this point you wouldn't be surprised. After a long session of tonguing, your mother finally pulls back, your sack stretching as her lips refused to relinquish their hold. You grit your teeth and fight the sensation of your balls literally being wrung for their sperm. This was it: the deciding moment. You'd either blow your load all over your mothers face before she even touched your shaft or you'd move your dick. There were no alternatives.
