Es malo meterse con su cuñado?

I have two experiences to share with you about that, the first one starts on a day when my sister was leaving, her boyfriend came to drop her off at the bus terminal in our dad's truck, and when he returned from dropping her off, he went back home to leave the truck and knock on the door to hand over the keys. Luckily, I was alone at home (it's very rare for someone to stay alone since we're a big family), so I opened the door and received them, I got excited and was thinking about how to take advantage of the situation, and I told him he could wait in the living room and I went inside, left the keys in their place while thinking what else to say or how to approach it, all that came to mind was going to my room, where I took off my clothes and stayed half-naked, and from there I yelled at him if he could come help me with something my sister had left behind, which was big and heavy. He walked into the living room and outside of my room, telling me he would come in, at that moment my heart was racing, I told him yes, put myself in front of the door, took off my thong when he entered, then I just said my sister said you should help me putting something here jeje, he looked surprised and only asked what I was doing, so I closed the door and went on top of him, throwing him onto the bed and climbing on top of him, since I didn't know how much time we'd have alone, then I got down to take off his pants and play with his cock, starting to suck it, and later climbed back up on him, uff I still remember the sensations he gave me while he was holding me and playing with my tits, then he held me against the bed and let me go without any saliva, although I didn't need it since I was already so wet, at the end he just sat down and got on his knees in front of him for me to suck him off until I felt like he came in my throat. The second one happened in a similar situation... My sister and I are almost identical twins, quiet ones, and we live each other in different places, but then we reunite all at my mom's house when possible to visit her. On those occasions, I always arrive first because of the distance to my mom's house. Once, I had a setback and my sister arrived first with her boyfriend, I didn't know until she got there, and no one was home, I put away my things, arranged my luggage and all my clothes among other things, until I heard someone arriving, opened the door and entered, I kept arranging my clothes thinking it might be my mom, when someone entered where I was and heard someone say 'what are you doing, you've already arrived, you won't let me arrive', and gives me a slap, I turned around feeling off, he saw my clothes that were arranged and grabbed an underwear that was there and said 'hey love, is this yours? Is it new? I didn't know it, it looks good sexy and small jeje, let me model it for you' and grabs me by the back and starts to undress me slowly, feeling like he had a hard-on, and starts kissing and touching me slowly, I started to get hot until I was fully turned on, and all I did was let go jeje, he started undressing me slowly, then he takes off his clothes, takes my hair and says 'come here my slut' I know you love having it up to your throat, and starts choking me with his cock, gives me slaps and hits my face with his cock until I'm on my feet and leaning over where I was, grabbed my thong and put it in my mouth, pulls my hair and my tits to give it harder, and I'm just whimpering like a slut who hasn't been caught, turns around and carries me in his arms to keep going like that, until we get to a table and he keeps putting it in, doesn't take it out until he comes on my face and thong, he stays there lying down and I went to take a bath, then I got out onto the street, and I think no one ever knew that day my brother-in-law had me 😅
