This is regarding something that happened when the restrictions were lifted from the lockdown. My girlfriend and I are both 28 and like most men I've always had a weird urge for her sleep with other men either in a threesome scenario or one on one with me watching. Weve often spoke about it during foreplay and its get us both excited especially the missus. It usually takes her a few minutes to orgasm once I enter her when talking dirty about wishing it was another man inside of her. Anyway back onto what happened, and why I massively regret it. We have been trying for a baby the last 5-6 months since the start march time. We both thought it would have happened especially both of us being furloughed and at home shagging most of the time. Like most people, our holiday was cancelled so instead as soon as the restrictions were lifted we booked a couple of nights away in Liverpool. The final night of our stay we got dressed up ready for a nice meal and few cocktails around the bars that were open. The missus looked a million dollars, short mid thigh blazer dress showing off a lot of cleavage. We decided to have a couple of drinks before the taxi came in our hotel. There was a group of 4 lads across from us who ranged from 19-21 as we found out. They were giving the missus a lot of attention and rightly so. This got me very excited and I think she secretly enjoyed the attention. A couple of drinks in and she went off to the toilet, I got talking to the group of lads and they invited me to sit with them which I obliged. They were complimentary of my missus and why wouldn't they be when she looked the way she did. She came back from the toilet and seemed surprised i joined the lads, she came over and sat down with us all anyway and we had a few more. I was loving how much attention she was getting but I dont think she did, I placed my hand on her thigh in the hope she would uncross her legs for them to have a better look up her dress but that was to no avail. Thankfully for her the taxi came and off we went to the restaurant. Over the meal I jokingly brought up would she have slept with any of them and she just laughed it off and said they were too young for her. But she did say she enjoyed the attention they were giving her. Anyway fast forward a few hours and we are in a nice cocktail bar were sat in the corner quite merry by this point when we notice the group of lads come in. They didn't notice us to start with and then one of them went to the toilet and saw us in the corner, when he came back he must have told the others cause they somehow ended up on the table next to us. We all got chatting a bit more and the drinks continued to flow and somehow shots of tequila and sambuca were going around. By this point the missus was starting to get quite drunk and when she gets like that she becomes very turned on. I began to test the water and placed my hand on her inner thigh again and in time she began to uncross her legs and open them a little. We were in the corner in a little a booth and she suspringly invited the group of lads to join us in our booth. Without any hesitation they joined up practically fighting to sit next to her. A few more drinks and she began to relax even more, her legs now were full apart. I began to move my hand up a bit further and she looked at me, smiled and bit her lip. I began to tease her by whispering in her hear, wouldn't you like to give these young lads a night to remember and asked her to take her thong off which I know she loves to do when she's been drinking. The lad who was lucky enough to sit next to her noticed and began to come in and sit a bit closer and closer every few minutes. By this point I was desperate for the toilet after a heavy afternoon and evening drinking so excused myself and the others moved out the way as I went. On my way back I noticed one of the other lads was now the other side of the missus so she was placed in the middle of 2 of them now along the back. On my way back to the table I got another round of drink and shots in. I knew she had enough but wanted to see how far she would go. I text her at the bar and said this round is for you to enjoy and our new friends with a wink. She replied, look under the table when youre back. I couldn't wait to get back and see, I pretended to drop my wallet when I came back and she had her legs apart and no thong on. I also noticed she had a hand on each inner thigh which was being stoked by the 2 lads. It was only then that I noticed the lad I was sat next to had her thong in his hand, they must have been passing it around, he noticed i saw it and smiled and winked at me the cheeky sod. Then he whispered to me that it smells heavenly and showed me a little wet patch in it. I was so turned on and jealous at the same time that she was letting these younger lads be all over her. I know I've pushed for something like this but it feels completely different when its happening. I noticed after a while that she had her eyes closed and was fidgeting around, I looked under the table again and both lads had their hands higher up and one of them was massaging her pushy lips. I was so angry but what could I do, I wanted something like this to happen. She eventually opened her eyes and looked me in the eyes and winked and smiled at me. I decided to call it a night and said we were leaving, she seemed a bit gutted but then to my surprise asked if they wanted to share a taxi back with us. The jumped at the chance. No doubt in the hope they'll get her in bed. Thankfully nothing happened in the taxi as I placed her to the window and me next to me, but she did keep her legs wide open for the lad opposite her in the 7 seater to get a full view of her pussy. When we got back to the hotel one of the lads, they cheeky fucker said your room or ours. Before I could say anything she said ours but not all of you. Just one or 2. Their faces dropped as did mine. Walking though the lobby I was ahead and they were all surrounding her like flies around shit. In the lift to our room they were all touching her and she began to moan, our floor was before there floor thank god, and she grabbed 2 of them by the hands and walked out and apologised to the other lads who looked as they were about to cry. The 2 she choose were absolutely buzzing as you could imagine, here was my beautiful girlfriend leading 2 young lads to our room. I was devastated. As soon as we got into the room the lights were barely on and one of them had he dress lifted up and slapped her bare arse. I was gutted at the thought of what was about to happen and went to the bathroom. I could hear a lot of giggle and when I came out she was already stripped and naked on the bed with the 2 lads either side of her kissing her all over but fully clothed thankfully. Well that didn't last long she sat up and leaned over to one of them and unzipped his jeans and slowly moved them down, the other lad just pulled is own down in anticipation. She got on all fours and started to play with one of their cocks, surprisingly she chose the youngest one of the group who wasn't the best looking and quite spotty to come back she took his cock first and asked the other one to eat her out from behind and he willing obliged. I was just stood there watching like a lemon. She then turned around to take the other cock in her hand but this time she took it in her mouth. Not long after she let out a groan the lad behind her was rimming her arse which she absolutely loves. The lad she had in her mouth had a lot of pre cum which I didn't realise until she said it tasted good. I was absolutely fuming now. She then proceeded to lay on her back and ask who was going to go inside her first. One of the lads had a condom that he put on and the other did and to my amazement she said it didn't matter. I was absolutely shocked, she's not been on the pill for several months as we were trying for a baby and he was already oozing pre cum into her mouth only 5 minutes earlier, I was absolutely raging as you could imagine. It weren't long until she had her first orgasm riding the cock of the lad with the condom on. Once she came she rolled over on her back with her head off the bed, she took the condom off his dick and got him to stand over her head as she began to take it in her mouth and deep throat him, the other lad then started to eat her pussy before putting his bareback dick inside her. He was gathering speed and the more he began to pound her moans became louder and louder as did her gagging as she was being thrust onto the other lads cock. The more she gagged the more he pushed his cock further down her throat. Then suddenly he announced he was about to cum. She held on to him and kept him in her mouth and then he suddenly stopped and grunted and emptied into her mouth. She carried on sucking making sure she fully emptied him before spitting it out over her chin and boobs. I'm not going to lie it was a beautiful seeing her being fucked by someone with cum all over her chin and boobs. The other lad then grabbed her legs and pushed them up near her head pushing down on her legs and began to plough her very deeply, he got his mate to rub her clit whilst he was gaining speed. The missus was moaning and shouting she can't take anymore then she let out the biggest moan I've ever heard and she orgasmed again. He juices were seeping out of her and was covering his dick in her beautiful girl cum. He was calling her his dirty slut and told her to taste her juices off him. Once she came down from her orgasm she was straight on her knees taking his cock in her mouth locking it clean. He then pulled her up by her hair and told her to bend over the bed and put her arse up before going back inside her pussy. He was spitting all over her covering her arse and then without any warning put 2 fingers into bed bum and then a 3rd finger whilst fucking her from behind. This must have been too much for him as he announced he was going to cum. I told him to pull out whilst she didn't say anything, he didn't listen and then suddenly groaned and collaped on the missus. He shout his bareback load into my missus who wasn't on the pill I felt sick. I dont think she realised what had just happened and smiled and kissed both of the lads quite passionately after it. She didn't even bother to run to the bathroom to try get it out she just laid on the bed with her head on one of their chests and stroking the others flaccid cock. I was absolutely raging and gutted she let one of the cum insider unprotected pussy. I felt physically sick. 15 or so minutes later then thanked her and kissed her goodbye and left to their room. I absolutely lost my head with her and asked how she could do that. All she could say was it was your fantasy aswell, which I couldn't argue with but I said but you let him cum inside. Her answer made me so angry and upset, she replied well you can't get me pregnant. I think it must have been the alcohol speaking as this was so out of character for her. Fast forward 2 and half months to now, and she's recently took a pregnancy test which has comeback positive. Weve been arguing a lot regarding this and ever since that night our relationship has not been the same. I dont think she even feels remotely guilty what happened and the fact she got pregnant and we don't know who the father is. I feel sick to think I could be bringing up the child of someone else, especially a young 19 years old baby.
