A experiment called "hourglass" (Game) 6 (Patreon)

Day 16

My goodness. It's true! Her growing is caused by stimulation. The video was an animation of a cowgirl milking and now her breast besides growing are milking. We asked her if she was pregnant. But the answer was that although she has "sex" with her boyfriend. He is too well endowed.

Girl: It's too big, you know?. He is afraid of hurting me but I guess I won't be a problem soon.

This time, we ask her to spend some time with him. "If you know what we mean. XD"
