Adventure with my husband's brother. Part 1

We've been married to my husband for 5 years, we always had good sex but after several years we started wanting to experiment with new things. We started having sex in the car while parked on a quiet street at night or during the day, we even did it on the beach, on the stairs of our building where we live, and that's when our thing started taking a morbid turn. A few months ago, while my husband was having sex with me, he started putting his fingers in my mouth for me to suck them and asked if I wanted two nipples, which he would like to see me have sex with another man at the same time as him, at first I was very shy about the idea but deep down it excited me and he didn't know it but I had been thinking and fantasizing about a foreign cock for a while, my husband's cousin's. Last summer we went on vacation with my husband, my daughter, his cousin and his girlfriend, and I. The house had two bedrooms upstairs, one with an attic where we slept, my kid and me, and downstairs there was the living room, dining room, and kitchen. A couple of times from our bedroom you could hear them having sex... like that young lady was screaming her head off, so we had to tell them to keep it down for the sake of my daughter. The guy is 21 years old, tall, dark-haired, with a great physique. One night I was awake and horny, my husband hadn't had sex with me because he was worried about waking up the kid, then he fell asleep. I couldn't sleep so I decided to go downstairs to get something and smoke a joint. I went out to the patio to smoke with a glass of coca, Fernet, and ice. When I came back in, I saw his cousin arriving at the kitchen, all sweaty, wearing boxers that showed off his cock, which was barely fitting into those boxers. I couldn't help but give him a once-over with my eyes and stay there with my mouth open looking at his cock. When he saw me, he said: Sorry, cuz, I thought everyone was asleep and came down to get something, I'm leaving. And I replied: No problem, it doesn't bother me at all, besides you look like you're hot, don't you want some Fernet? (Always a slut without fear) (to success) He accepted, came closer, passed my glass and started drinking. My head, my pussy were in ecstasy, it was a situation like a porn movie. We started talking about random things, had been 5 minutes and I asked him + but don't you have to go back now? Your girlfriend must be waiting for you... -No, she took everything from me, including water, and then fell asleep, that's why I left. + Sorry, I don't want to be forward, but yes, if what they hear is fuck and the girl moans, it must leave her exhausted jaja He laughed and timidly told me - It could be, but it wasn't that much, in your case you left the guy tired and asleep? Jaja At that moment a thousand things went through my head, but looking at his cock won me over... I said + Nothing of that, today I didn't get touched at all, that's why I'm here awake.. I'd need a reconciliatory fuck like you gave your girlfriend.. jaja I laughed, and inside I felt a touch of guilt but my heat won out. - Uhh how bad, he must be tired, but who knows if he wakes up in the middle of the night and helps me sleep jaja I was already feeling bad for throwing myself at him like that, but when I looked at his boxer his cock was getting hard and it was impossible to hide it, he liked what I was saying. And I thought about going all or nothing, if he hadn't liked it he wouldn't have accepted the Fernet nor would his cock have started getting hard.. I came closer a bit more and said + I don't think she'll wake up, and you seem to have experience in helping people sleep... I came closer, almost putting my mouth against his, it was inevitable, we started kissing, with his hands he started squeezing my ass, kissing my tits, I started touching his cock, he turned me around while kissing my neck, rubbing his enormous cock on my fat ass, both of us were in heat. I felt like the sluttiest one, I couldn't believe what I was doing and it didn't matter to me. I got down on my knees in front of him, took off his boxer and automatically... In love with his cock, it wasn't just long, it was very wide and veiny. I started rubbing it against my face, passing my tongue over it and eating it on both sides until I reached the head. When it was already hard, I looked at him in the eyes, held it with both hands to put it all the way down my throat if possible. But then he stopped me, came. He apologized, told me he wouldn't tell anyone but that he couldn't help it, would feel too guilty, since his wife and I were raised together. Of course, after he had fingered my ass and let me start sucking his cock... but well... what's done is done... After that situation, I went straight to the room where my husband was sleeping and started sucking his cock and fucking him thinking about his cousin. Time passed, the relationship with his cousin remained the same, everything stayed in that night, without witnesses and pretending it didn't happen. Returning to the present, when my husband told me about the threesome, I already had in mind what he wanted but couldn't say... Or at least so it seemed!
