Trio with My Stepsister and the Building Engineer on Their First Day of Work

The new engineer was just getting to know the work, but he ended up knowing much more. My roommate and I invited him to "have a drink" and he fell straight into our hot trap. Between daring looks, clothes that fall off by themselves and a desire impossible to hide, we end up in an intense threesome where the rookie showed that he came prepared for anything. Pure Latin fever without control.
