The serum affects the male's package in a great way, growing the size of their cocks and balls, along with the cum production. As both of them cum inside me, they haven't stopped. They are growling and grunting, as I can feel both of their cocks pulsing, shooting their loads inside me even more and more. My stomach starts to inflate as the cum keeps pushed inside me. More cum spills out from my rear, pooling on the floor.
I can feel they both still cumming, and they still don't stop X.X
