Another incident recently happened yesterday. It's been 2 weeks since I had sex with my trainer. I was feeling sexually frustrated, but I felt too guilty to have sex with him again without my boyfriend knowing and accepting it. My boyfriend got a membership at the same gym and he wanted to come along with me while I go. I thought this would be good because I'd be less tempted to cheat on him if he's with me.
My gym trainer saw me and I hesitantly introduced him to my boyfriend. I was blushing a lot when he came over and he could tell. As I was working out, he told me he'd help me stretch. I was hesitant at first, but I thought "It's stretching not sex. It'll be fine." We went into a corner and as he helped me stretch, I started become really wet. He was being more handsy then necessary, rubbing my thigh and love handles. I was getting super horny and at some point, a wet spot emerge on my yoga pants. When he noticed this, he didn't stop to slowly rub my pussy. I let out a soft moan.
"Do you want to fuck again, babe?", he said. "I..umm.." I hesitated. I felt like I was betraying my boyfriend again, but I wanted sex again so bad. I thought to myself, "one more time, it's just one more time and I'll be done."
We went into an empty room that they use for yoga. My trainer didn't hesitate. He ripped my yoga pants and pulled my panties to the side. Those were my favorite yoga pants but I was so horny that I didn't care. He rubbed my pussy up and down and I thought I was gonna orgasm right there. He pulled his penis out and hovered it right over my pussy. Why wasn't he sticking it in?
"Tell me you want this dick," he said. I didn't want to say anything because I felt too guilty, but he wouldn't stick it in if I didn't say it. "I want this dick," I said shyly. "What about your boyfriend," he said. "Please don't make me say it. Please don't," I pleaded to my trainer. He just rubbed my pussy more and told me to say it. "My boyfriend has a tiny dick" I said. I felt terrible degrading my boyfriend infront of him, but I wanted his dick so badly. Say it louder. "My boyfriend has a tiny dick!" I yelled, this time on the verge of tears from my guilt. He finally stuck it in and I orgasmed from the first pump.
He fucked me for a solid hour in that room. I got a call from my boyfriend during sex. I told my trainer to stop pounding me when I talked so it wouldn't sound suspicious, but he started fucking me harder when I was on the phone. I had to tell my boyfriend I was running to explain my panting and my moaning. When he was done, my ass and pussy were covered in cum and I felt so damn good. When I went back downstairs to leave with my boyfriend I had to wear a towel around myself because my yoga pants were ripped from the back and my panties stretched. As I was leaving with my boyfriend, my trainer winked and I blushed, feeling guilty but knowing how good it felt.
I tried watching interracial porn to my boyfriend to start cuckolding, and I brought up the size of the men. However, he just brushed it off and said that size doesn't matter. I didn't say anything.
I hope I can convince my boyfriend to let me sleep with other men, but I don't think he'll budge.
