Yes, with a little extra muscle

“No problem Mom, would you rather your breasts only be half affected by gravity, or always have enough muscle to carry your weight?”

“I'd love to cancel my gym membership, I'll take the muscles,” she replies candidly.

This time, your mother looks down expectantly at herself to inspect the changes as they happen.

You ogle her breasts as they start to firm up and become much perkier than before. They're still the same obscene size, but are slowly rising to sit higher on her chest. Her nipples gradually rise from a downward angle, up to a proud horizontal position. Her magnificent tits are a perfect blend of both teardrop and spherical forms. Just below her impossibly huge and buoyant globes, you see a hint of abdominal muscles appear on her toned stomach. She runs her hands along the grooves of her washboard tummy and giggles with glee. The laughter sends her supple, renewed tits into a tantalizing bouncing fit. Unconsciously she straightens her back and her chest thrusts forward as her posture improves - you can only imagine as a result of newly acquired back muscles.

Luckily you don't have to imagine long as she twists around, giving you a great view of her developing back and giant ass. Her previously fat butt has toned up and gained an irresistable shapeliness that only thousands of heavy hip thrusts could hope to unlock. Your mother brings her arm to her side and extends her palm backwards to cup one of her enormous butt cheeks. Her fingers sink into the spongy flesh but are slowly pushed back outwards from the gradually increasing tightness. She looks at you inquisitively as she proceeds to wobble and bounce her magnificent ass for you.

She twists her torso around to allow you to see both her humungous ass and gigantic titties at the same time. She drapes her other arm across her chest below the nipples and uses it to squish her breasts against her frame. The massive melons bubble up and spill over her arm, her rock hard nipples just barely in view. Your mother continues to tease you, wobbling her newly toned breasts and butt and looking to you for a response. Your raging boner throbs with need against your leg.

The changes slow to stop and your mother turns to gather her chair.

“Thank you honey, that's so much better.”

She drags the chair around the edge of the table towards your seat, moving with ease thanks to her newfound strength. She plonks herself down next to you, resting her head on one elbow and turns to look at you with big innocent eyes.

“Now, about that fun you mentioned...”

Your mother's free hand snakes its way across the top of your leg and rests on your inner thigh, her fingertips dancing along the shaft of your hard cock.

“What did you have in mind dear?” She asks.
