There's not much privacy in the missionary quarters. Elder Rim and Call share a bedroom together, sleeping in twin beds and showering in a small bathroom. While Elder Rim is in the shower, Elder Call pretends to brush his teeth at the sink. But he's really curious as to whether his Mormon brother has a bigger cock than he does.
Elder Call moves in and the lads compare. The bespectacled lad definitely has the bigger piece of meat. But Elder Rim doesn't care, he bends his fellow Mormon over the sink and demonstrates why he's garnered a reputation with a few of the other missionaries.
