When you picked out the t-shirt from an out-of-town second-handed store, you didn't imagine the message on the front would become accurate so quickly.
You intentionally chose one that would hang off your lanky body like a blanket to eventually fit into, a goal to aim toward for your workout. The words "FIT TOPS" written on the front give it an extra boost to your motivation. When you try it on later for a Before picture though, the your body quickly grow to fit the clothe. Muscle grew and strengthen, pecs inflated, shoulder broaden, none of your body parts were left out of the growth.
You soon after rushed to try out your new body in the gym. Your performance didn't disappoint you.
The constant horniness after the studification is becoming increasingly distracting though. And new desire to fill up the other gym-goers with your baby batter and dominate them surprised and driven you. It seems "FIT TOPS" on your now tight-fitting shirt has double meanings.
Not that you mind, you are loving this new confidence and sexual readiness, and the satisfied bottoms you bred love it too.
