[MF] Sexual tension with my Sister in Law

Sexual tension with my sister in law.

My sister in law had moved in with us for a period of time after her boyfriend broke up with her. While she was living with us we kinda started flirting a little bit more like being overly friendly because she was my sister in law. One night she was talking about how her butt was flat and I said it wasn’t and gave it a firm squeeze. She had a surprised “oh” come out. From then on she didn’t really care if I touched her. We used to work at the same place and she showed me pictures of her ass on her phone and she had her nipples pierced and I flicked on because she kept messing with me and it hurt her and she was checking her nipple out to see if it was okay and she didn’t mind me looking. One night we were going out to the bars and she didn’t like how I had my converse laced up so she sat in front of me and re did them. She said “I’m surprised your not messing with my boobs” so I stuck my hand in her shirt and massaged them and punched her nipples and pulled them out. She pulled them out more and let me take a picture of them. Then she was done with my laces so I told her to pull her pants down and at first she said no but then she started pulling her zipper down and pulled her pants down around her knees and put her elbows on the counter in her kitchen. I got down and started rubbing and squeezing her butt cheeks and took a picture of that as well. She would also willingly show me pictures of her pierced tits if I asked. I enjoyed that stuff but once she got pregnant by her ex boyfriend they got back together and she moved back in with them and I haven’t really tried since. I would like to but don’t really know how to start doing it again.
