I was made to cum by someone other than my husband - I just wanted to be beautiful for you!

"It feels so good to be loved...I can't resist..."
Sakura, a married woman who is about to have her wedding, decides to join a gym because of her plump figure!
At the gym, she has a balance ball pushed against her buttocks while she is doing leg spreading exercises on her back, and she also has to support a heavy barbell while being stimulated in her private parts!
Even during the fitting at the wedding venue and while her husband was holding her, Sakura couldn't help but remember that day at the gym. But her body can't forget the pleasure she once felt...
-Her erotic body can't resist being desired by a man other than her husband!
