My sister, who is now at that age and conscious of her figure, started exercising at home for a diet! She keeps trying to restrict her meals and exercise, but the sudden dieting has caused her to accumulate stress, making her irritable every day. However, her outfit during her diet is focused on ease of movement and is quite sexy! I never noticed before, but my sister unexpectedly has large breasts that bounce around a lot! Plus, if you look closely, her nipples are see-through from the sweat! Seeing her like this made me get an erection, and she noticed, but to relieve stress, she grabbed my dick!
