My current girlfriend said that she dated Shroud from the way back, she said that he has a fat cock. I broke up with her, because I can't fill that "hole", I cannot carryout the thought that my dick has to go through such underground chamber, the size is comparable to the Hang Son Doong, (the largest cave in the world) but bigger...
Word on the street that shroud has a fat cock. Rain drop. Drop top. Shrouds fat cock.
