By: Philip Schaff

Religion and Christian Theology Collection

Excerpt: The genius of Lactantius suffers a sad transformation when unclothed of vernacular and stripped of the idiomatic graces of his style.

Jarek

By: Rigby Taylor

He’d only agreed because he wanted to seem tough, and hoped if he felt her up in the water and fucked her afterwards her mates would stop spreading rumours he was queer. The cars screeched to a halt at the boat ramp. Everyone piled out and headed for the small beach until Bob’s girlfriend reckoned there’d be eels and leeches in the river, so she refused to go down. Then the ...
