You're in your car, chilling, doing whatever you want. It's started to rain more and more. Then you saw a biker, obviously muscular. He's dressed in cargo pants and compression shirt, easy to notice his muscular form. But he's dampened by the rain, and riding a bike during rain is risky. You felt bad for him so you let him in your car during the rain.

He's sitting in the passenger seat, still wearing his helmet. He lift his compression shirt a bit, just showing his abs, as if it was to make his compression shirt dry faster. Maybe it's just to show you his abs?
