My Home upgrade

I (33) inherited an old house, a wooden-frame house with a basement. I decided to upgrade it by raising it and building underneath. I raised the house and framed out the addition. While I was working on it one weekend, I was approached by a mature woman (51). She lived nearby in a boarding house; rentals were hard to find locally. I wasn't intending to rent out any part of my home; I just decided to enlarge it. But it got me thinking; I decided to enquire about rentals in the area. Finally decided to rent out the ground floor area and live in the upstairs part myself. But wanted the basement for my personal use only; a quick redesign followed. At the rear right of the ground floor area, I would install a small elevator and stairs to the basement from the upstairs, and access to the backyard via the ground floor. I framed in an access door to the ground floor for future installation, but sheeted over it while it was being rented. Getting close to finishing the whole build, the mature lady visited me again. I had seen her watching my progress during the construction. That time, she made me an offer that shocked me at first, but also interested me a great deal. Her offer was regular sex with her and another lady (54), who, like her, rented a room at the boarding house. The sex was in addition to a lower rental payment. I'm not the greatest looker and don't do all that well at dating. Both women were good-looking for their ages; I agreed I would think it over. I had already decided to accept but wanted to at least look like I was thinking it over. Two days later she was back, and I told her I was agreeable to the arrangement. I was now living upstairs full time. She offered to stay the night with me; I accepted. She left to get some things while I cleaned up from painting the last room on the ground floor. She returned forty minutes later with the other lady, and they brought dinner with them. They were both staying the night with me. I had always wanted a threesome, but hadn't succeeded until then. They moved in over the weekend, and I added an access door to the basement and upstairs. It hasn't been locked since its installation. The only other access was an exterior staircase. Both women are teachers, and their wages don't allow them to rent locally except at the boarding house. Sex is freely available from both, not just as a way to get lower rent, but for mutual satisfaction. Through them, I have met another younger teacher (30) who I have started dating. We have started a sexual relationship, which also includes the other two teachers. She, of course, now lives with me and enjoys group sex with the other two included. I really fell on my feet as they say.
