Straight girl, except for my landlady

I am in college in the south USA. I have an elegant second floor apartment. I can't afford this area of town, it's full of rich people and I am not one of them. In looking for a place to live off campus last year I saw an online ad for this place. It was beautiful, super safe area, and way too nice. No price listed. In online chat, then video calls with the owner she seemed really nice. She was married, 53 years old, very attractive, she could have passed for her mid 30s quite easily. In seeing her in person I could see she was really toned, more so than me, about a dress size 4, very nice body and C cup boobs. She was very handsy in a way. Grabbing my hand in hers, to walk upstairs and show me around. She would constantly touch me. I'm a bit sluttish in my sex life, started having sex when I was 15 and by that time, at 18 I'd had 29 guys already and no holes or cleavage left untouched. She made mention that I could have other people over, even for the night should I want, just not move in permanently. I told her I wasn't seeing anymore at the moment and she remarked " A beautiful, young girl like you with that body? I don't think that will be too long before you have several young men after you, even older men" .

On my second trip she mentioned her husband who was 10 years older hadn't had an erection in 5 years and she was without, and hoped I was doing well in that department unlike her. We got to talking, actually smoked some herb, and she opened her blouse revealing her big boobs. Drooping down a bit like a teardrop they were flawless though, light brownish nipples and she told me that I wouldn't have to pay rent if I were living here. Even then I asked why, and she moved towards my chair. She put her chest within two inches of my mouth and I started sucking on one of her boobs. She was grabbing the back of my head, pulling me into her, "Bite it, bite me, please do it hard" she begged as I bit her nipple and areola and used my finger and thumb to pinch the other one so hard I couldn't believe a woman could take that much. Pulling away, I knew what was coming, she moved in to kiss me and I let her. I pulled away and asked "Is this what I have to do to live here?" she answered me "Yes, love, this and more".

So I made love my first time with a woman. It took a while to get used to it but actually I really like the taste of pussy now. Before when guy, for some reason especially older married men, would pull out of my pussy and put it in my mouth I always wiped as much of my juices off his cock as I could before taking it in my mouth. I love pussy now. I still love cocks and she likes when I have a guy over. When the guy leaves, I call her and she comes upstairs and cleans me out and makes me cum even better than I did getting fucked. Her husband knows, he's actually had to take their spare bedroom when she has be overnight in her bed with her.

I'm straight, but do eat her pussy and let her eat mine, we grind, trib, vibe play. I have lesbian sex with the bi woman and get free rent. My parents think that I somehow got this great deal on this fabulous place. I guess I did!
