Bra and extra-weight

"I'll also give you some extra weight, so you can experience what breasts weight like." Stephanie said with a wicked smile. "I'm currently a D-cup. So I think about 600cc, each." She tossed the bra at you and stood up. "And make it for the rest of the week. That'll be a good lesson." She left for the kitchen.

Dumbfounded you looked at her leaving, followed by hearing the sound of water running. You knew that when she would come back, she would somehow make you get the bra on, so getting it on yourself would be the least embarrassing option. You took off your shirt and put your arms through the the loops. You pulled the strings up and tried to hook the bra behind your back.

"Let me help you." Stephanie said as she came back. She placed two bags filled with water on the table and stepped behind you. In just a few seconds she had the bra hooked up. Then she took the bags and placed them into the empty cups. The weight from them pulled on your shoulders. You were quite surprised by how much it was. "Quite a weight, isn't it?"

After a little while getting used to the weight, you put your shirt back on. You looked down and saw that you now had quite the big bosom, way more than a normal boy should have. And you had to spent the rest of the week at work with it.
