"Hold on Mark, lets try this one." You pick out a condom thats big
enough for both of you. "Here let's try this one." You walk over to your
brother and stick you cock in.
You and Mark rap your arms around each other so there is enough room for
both of your cocks. Then you start masturbating, causing cum to flow
from both of you cocks. You both moan in pleasure as you orgasm. Your
both so caught up in pleasure that you don't realized the condom has
started bringing the two you even closer...
