Another update on me and my sister in law. So it’s fair to say after the last couple interactions, we have an attraction towards each other. After our cycle and seeing her tits once again after slipping out her jumper, I asked if she wanted to go wild swimming which she agreed to! A week later we ventured to a small secluded loch together, we set up our things and as I turned around she’s running into the loch completely naked with the most sexy juggling little bum. As she enters the water I’m still fully clothed and she shouts “what are you waiting for, come on!” So I look down and see her pile of clothes on the floor and started to undress myself down to my boxers ( while she’s watching me the whole time ) I go to walk towards the loch when she shouts “that’s not fair take all your clothing off it’s wild swimming after all!” So I take my boxers off while I have a semi from watching her bum juggle while she ran and seeing her underwear on the floor. She doesn’t take her eyes off me as I run towards the loch with my cock flapping around ( she looked some what impressed ) so we are both in the loch and swimming around nude for about 30 minutes and when we decide to get out. We get out at the same time, she’s in front of me and I’m expecting her to grab her towel and get dressed but she walks over to her chair and just sits down fully naked, so of course I stay naked and sit down next to her on my chair. We were chatting away and she complimented my body and I said I look good while she looks down at my cock, I chuckled and said “thank you, you have an amazing body also you look really nice” as I look her up and down. She smiled, tucked her hair behind one ear and leaned over and kissed me on the cheek and said “that’s so nice off you you’re so sweet” at this stage my dick is starting to grow harder and I turned and said “ your lips felt nice and warm for just being swimming, I know you’re my sister in law but we are sitting naked beside each other and you’ve jus kissed me on the cheek is it okay if I kiss you back” she didn’t say anything but just looked at me and we kissed. It lasted about 10 seconds and my dick was rock hard which she obviously seen and said “ wow look at that it’s doubled in size, sister is lucky!” After the kiss and her saying that it was a little bit awkward and said to each other to keep it between us. After that we both got dressed, and headed home and I invited her to dinner through the week and both agreed we should go for another cycle or swim soon. She obviously wants to see me again but doesn’t want to make it out we are spending a lot of time together. She turns me on a lot and now we’ve kissed and seen each other fully naked I think it’s only so much time until we end up fucking. I really hope she’s not teasing me. But this is major progress for me and I can’t wait for it to go further
