Caught in the act: A hardcore 4some with stepdaughters

The scene opens with two stepdaughters, both in their early teens, lounging on the couch with their stepfather. Things quickly heat up when their stepfather's father in law walks in and joins the fun. The girls are clearly excited to have another man in the room, and they start flirting with him immediately. The stepfather, who is clearly uncomfortable with the situation, tries to intervene, but it's too late - the girls have already caught the father in law's eye. He's instantly turned on by their innocent looks and beguiling smiles, and he can't resist their charms. The girls start to undress, revealing their tight bodies and perky breasts, and the father in place is more than happy to join in. The foursome starts with some passionate kissing and caressing, before the girls take turns pleasuring each other and the father in law. The scene ends with the father in law shooting his load on top of the girls, who are clearly thrilled to have been caught in the act.
