Russian voice acting - Sperm fireworks for my stepsister and her friend

Ricky wants to go to a party with his stepsister and her friend to find a girl and have sex, but they don't want to take him with them. But he doesn't give up and offers to run out and get fireworks for the girls, just so they'll take him. Soon he brings them back in a box... along with his dick. His stepsister is shocked, but her friend is interested. The party seems like a second-rate idea when they can stay home and have a threesome.
