A group of young devout Christians is gathered up at home for their chastity club to discuss the Bible and the importance of maintaining innocence until marriage. But the teen girls are a little more curious about sex. Instead of the Bible these two little sinners hold a guide for the best possible sex! As the women open up a sexual book that they’ve found, they look at all the different positions before excusing themselves and going upstairs to try some of them. The girls want to practice before getting married, but their stepbrothers quickly catch them. As they walk up, they see the girls trying out missionary as they jolt back and hide the book, but it’s too late. The girls beg not to be thrown out of the club, and the guys act as puritans while the teens masturbate their sins away. Both girls spread their legs and start rubbing their pussies in front of the boys. Instantly getting erections from seeing their sisters in such a state, the girls notice and point it out. They’ve thought of a plan to improve everything, including grinding them with their clothes on. With every graze of their bodies on their boners, they get harder. Feeling like it’s unfair that they’re the only ones naked, the girls demand they get stripped. With each moment passing, the naked girls can’t control their lust, and they eventually start sucking their cocks. They care about sins no more as they let them ride their cocks. Wanting more touching, two naked girls get on top of one another and start eating each other out while the boys ram them in doggy. Losing the rhythm, their dicks fall out, but their stepsisters are there to help with their mouths. Without hesitation, they switch partners and begin hammering their own stepsisters. Both naked girls moan and have their very first orgasm. The boys feel their shafts throb with each shove before pulling out and spraying their loads.
