So I hooked up with my 18yo "step"-niece at Christmas-time and New Year's. We had fun, we've been flirting a lot and talking and sending dirty stuff back and forth since. We decided the be FWB (family with benefits,) and S wanted to be my free use niece. I need to say right now that a lot of people ask me to share photos and the like, I cannot share those as they are not mine and she and I have an agreement about fair use, she gets to decide who she shares with.

Okay on to this last weekend.

S sent me a text on Friday, she had a really bad week with lots of personal stuff going wrong and she needed a distraction. Her words where "Fuck me until I can't remember who I am or my name." Now I am concerned about her well being, we do care about one another, BUT she gets me fucking horny as hell when she gets all vulnerable and like this and she knows it.

I picked her up when I was done with work and once we got to my car she immediately was in my laps riding me and marking out. She barely got my pants open before she was pushing me inside of her. It was so fucking hot, and she wouldn't let up even after she'd made me cum. I didn't want her to either. We were there fucking in this very well lit parking space for maybe an hour, before she going into her seat and I caught my breath enough to drive to my place.

We drove in almost silence, S didn't want to talk, and anything I asked she told me to shut up and would stroke my cock and tell me that was all she cared about. When we pulled into my place she had sat very quietly, I parked she just sat there. So I got out and opened her door, picked her up and carried her inside (my cock out but under my coat).

When we got inside she striped down to just her stalkings and I started the fire and made her a drink. I asked if she was hungry, she told me she didn't want to talk or anything, but that I should just fuck her and make her scream. She needed to fill me, and she told me not to use any more condoms. I've had a surgery so I'm not worried about not using condoms.

She did EVERYTHING I told her without question for the next two days, she ate what I fed her and we drank and played. Eventually, Sunday night we were panting and sweating after a lot of rough activities, she snuggled into me and told me why she'd needed this weekend. I ended up holding her until she fell asleep.

This morning I didn't wake her up for her train, and I figure I'll let her stay a few more days if she needs, I am sure she won't complain too much about staying longer.
