I (m28) was meeting a few friends at the beach but there wasn't any room for three of us. 5 went in the car and 3 in a coach which would arrive 2 hours after the rest of them. Me, my girl (f29) and Kay (f29) went on the coach. It was quite exciting at first but after the first hour, we all fell asleep. We woke up when the coach stopped. We found out we were just having a short break. I was sitting alone while my girl and Kay sat together. They told me that they are going to the restroom but I just stayed in the coach. That nap made me feel more tired. I closed my eyes again but after about a couple of minutes, my phone rang.

It was my girl who told me to come out because there's a big queue for the toilets so they wanted to go round the back. They wanted me to keep a look out. I met them outside and we went around the back where there were no cars or people around. There was a drain by the wall which they decided to use. I stood close to the corner of wall so I would not attract any attention but also facing away from the girls. I told them that they are in the clear and my girl start to go first.

She pulled her jeans down and squatted over the drain and start peeing. I quickly turned to her as the sound made me look but I instantly turned away and kept my eye on the coach. Kay laughed as she saw me look and said, "did you like what you saw."

I apologised and tried to not make it worse. My girl, on the other hand, made it worse. She said, "he gets a boner whenever I go and he's in the bathroom."

That was private information. Why did she just say that? I said, "babe, not in front of Kay. Please." While I said that, I accidentally looked at her again which started to excite me. I looked away again and Kay giggled again.

Kay asked my girl, "do you go when he's in the shower?"

As she said that, my girl farted and let out a stream of pee which made me really uncomfortable as my erection was getting too tight in my jeans.

My girl replied, "yeah, but mostly when he's brushing his teeth or shaving or something. I go in deliberately because I love getting him hard. That fart definitely gave him a boner."

I moved my leg around to shift my erection around and Kay started giggling more, "yup, you've definitely given him a hard one. It's showing through his jeans."

"Babe, not now. Please. It's not funny." I pleaded.

My girl took out some tissue from her bag and wiped herself then told Kay she can go. I kept my eyes focused on the coach and tried to control my erection as best as I could. My girl leaned on the wall looking at Kay take her jeans down. My girl then reached for my hand and pulled me closer to her. I couldn't see the coach anymore and was face to face with my girl. She stroked my erection which made it harder. I pulled back and whispered, "what are you doing? Not in front of kay."

My girl replied, "I'm horny as fxxx. Come on. Kay won't mind." She reached for me again and pulled me closer to her. Kay giggled again then squatted down. My girl told me to look at her as she stroked my erection.

I looked over at Kay while my girl looked at me, Kay started to wee and I immediately got aroused even more. Kay moaned as she looked at both of us, "that's so hot."

My girl looked at her and noticed something, she said, "he likes when I don't shave for a while too, he would go to town with your hairy pxxxx."

Kay moaned again as I was finding it too difficult to hold it. I said, "babe, don't tell her those things."

My girl said, "it's only Kay. But now I know why you like it so much. Her bush and pee is turning me on so much."

Kay said, "you're both turning me on like sxxx. I'm going to squirt just looking at both of you."

My girl replied, "I want you to fxxxing squirt, Kay. I want to see that hairy pxxxx squirt for me." My girl then undone my belt while I resisted but she didn't allow me to stop her. I was turned on and embarrassed all at the same time. She pulled my jeans down to my knees and my boner tented in my boxers. She then stroked it in my boxers and said, "Kay, this is my treat every night. Any hole I want it."

Kay's mouth dropped and also paused her peeing as she looked at it, "you lucky girl. That's much bigger than my vibrator. Oh, xxxxxxxx (my girls name), please show me it."

My girl pulled my boxers down without hesitation as my cxxx sprung out for all to see. I closed my eyes as I was too embarrassed. My girl grabbed on to it and started stroking it up and down. The head of my cxxx was throbbing and the shaft was pulsating. Kay started to pee again but this time, also start rubbing herself.

My girl pulled me closer to Kay and told me, "look at her, don't you just want to fxxx her too tonight."

I gulped as Kay answered, "shall I join you both tonight. I'm gonna be stuck with Laura anyway. I wouldn't mind having a three way with you tonight."

My girl stood straight and pulled her jeans down again and start fingering herself while stroking me again. I didn't know what was going on. I was close to cumming so many times.

Kay finished peeing and wiped herself then came closer to us. My girl squatted down and took my cxxx in her mouth and start sucking it. Kay knelt down besides us. My girl took my cxxx out and kissed Kay on her lips. Kay licked her lips after, smiling. This made me uncontrollably say, "ah, I just want to fxxx you both."

They both smiled at each other. Kay then looked at me and said, "what hole do you want?" My girl said, "he loves fxxxing my axxhole. Show him yours and watch him shoot."

My girl took my cxxx in her mouth again and start sucking on it hard as Kay stood up and turned around then bent over, opening her legs slightly. Then with one hand spread her axx cheek. She exposed her anus to me while fingering her pxxxx with her other hand. She had a cute circle of pubic hair around her anus which made me hold on my girl's head to go deeper in her mouth.

My girl moved back to take a look too then told me, "finger her axxhole."

I reached for her butt and started rubbing her anus with my finger then slowly inserted it in. I slid it in and out while Kay moaned.

Kay start fingering her pxxxx faster while I went deeper. Her butt clenched onto my finger making it really tight. So I pushed in harder. It was turning me the hell on. My girl felt me get harder in her mouth.

After about a minute of fingering her butthole, Kay took my finger out as she let out a fart and that was it. That was the trigger that made me shoot my load in my girl's mouth. Kay put my finger back into her anus but I was already having the most amazing orgasm ever. While I was shooting, I fxxxed my girl's mouth harder and finger banged the hell out of Kay's anus. My girl grabbed on my butt as she let her cum drip on the floor. She moaned with my cxxx still in her mouth.

Kay said, "oh sxxx. I'm going to cum. Fxxx my axxhole hard, xxx (my name)" and that was her trigger. Her hairy pxxxx squirt a few times splashing on the floor. Her whole body shook while my finger was still in her. She took my finger out and farted again while her pxxxx let out another squirt of cum then Kay put my finger in her mouth and sucked on it then took it out and told me to sniff it.

I didn't because I thought that was too much but my girl took my cxxx out her mouth, spit out my cum then took my hand and sniffed my finger. She said, "ah, that's so fxxxing hot, Kay."

Kay leaned back on the wall while pulling up her jeans saying, "don't tell anyone we did this."

I got a tissue from my girl and wiped myself clean then went onto the coach again. They came about 2 minutes after.

Then we set off after about 15 minutes. As I was already relieved, I wasn't in the mood for anything kinky so just enjoyed the rest of the day at the beach with the friends and by the evening, we hit a few clubs and went to our hotel. Kay ended up not coming to our room. She said she couldn't be slack to Laura because she'd be alone otherwise. My girl was also swamped out, we didn't even have sex that night. We were too tired. We woke up with mad headaches from the clubs. Nothing else happened the next day. We checked out and went back. The coach ride back was also different as the girls wanted to fool around again in the break but we all ended up sleeping throughout the whole ride back. Pretty boring really.

Kay visits us at home but nothings ever mentioned about that trip. Maybe they talk about it but nothing in front of me. Kay is too normal in front of me like nothing ever happened.

My girl has said her name a few times during sex when she wants me to fxxx her harder which does make me go on a wild one with her. But I'm too afraid to mention it because even though she was cool as hell that day, my girl snaps at me if I ogle at a random girl. Like for instance, whenever there's a sex scene in game of thrones and I'm just enjoying the scene, she'll snap and start throwing sxxx at me. So, yeah, I don't ever mention it. I do fantasise about Kay joining us in bed though, but damn it, it hasn't happened again like that.
