You walk over to the mirror to see yourself change, noticing that Jared’s Dad must work as a swimming coach, judging from the Speedo-branded t-shirt and shorts and the name badge from a high school listing him as leader of the swim team. Obviously, the uniform is way too big for Jared’s body, but that changes as you feel yourself start to grow.
Your legs and torso stretch upwards, legs packing on muscle as well to support your heavier frame. Your calves and thighs swell up, becoming those of a frequent swimmer, thick and muscular. You lift up the shirt to watch your abdomen contract into a lean six-pack, and your pecs push out to form huge slabs of muscle. Your shoulder and back muscles bulge out and reshape too, and your biceps thicken, helping fill out the previously loose t-shirt. You can see your face become vaguely similar to Jared and his brother, but much more mature and attractive, with sharp angular features.
You look at yourself in the mirror once more, now a hot swim coach in his early thirties.
