In the dim light of their shared quarters, the missionaries' breaths syncopate as one reaches out, tracing the other's chest, pausing at the belt. They undress each other slowly, reverently, like unwrapping a sacred gift. Their cocks spring free, hard and aching. They explore each other's bodies with tentative fingers, their touches becoming more urgent, more demanding. One missionary pushes the other onto the bed, spreading his legs, and buries his face in the other's crotch, licking and sucking until he's rewarded with a shuddering moan. They fuck each other, missionary-style, their hips moving in sync, their cries of pleasure echoing in the silent room. They cum together, their bodies shaking with the force of their release, their taboo lovemaking complete.
