Gym.

"How about the gym?" you suggest.

"That sounds good to me." She gives you a reassuring smile. "You might want to wear shorts though. It's going to get hot in there. How about you meet up with my outside in just a few? I'll get changed, and we'll head right down! It'll be nice to be indoors. I'm sweating, even in this top."

Trying to shake any sexual imagery from your imagination, you make your way back to your room to throw on a pair of shorts. You then make your way to the front yard and wait. After a few minutes, she finally steps outside in a pair of small black shorts and a grey sports bra, which you thought at first would be better, but it only squeezes and pushes her massive breasts up. The straps of the top struggle to contain her cleavage, which jiggles every time she moves.

You both make your way a few blocks down to a small gym.

Inside, there's hardly another person to be seen. She takes a deep breath and sits at one of the machines. Her arms lift the weights up and down, causing her bosom to bounce with each thrust. You're left standing rather awkward (and tense), as you aren't entirely certain what to do yourself. So, you sit down at a machine across from her and begin to work your forearms.
