This happened not too long ago, Im 24, my friends bro jimmy was 18 and he asked if him and his 18 yo gf could come over maybe have a couple drinks and sleep there. My friend let his bro drink so I said sure at least I'll have some company. everything was cool theyd both had a couple but were already tipsy around 1am he asked if I had any pporn, I started to laugh I said naw man I cant let u watch your bro would kill me for sure. He said his girl Tammy hadent seen any before. I let him and his girl watch some lesser hardcore stuff I had. All 3 of us were on the couch I looked over and they had begun making out so I just kinda watche figuring it woudnt go to far. I watched as his cock began to grow in his shorts, she meanwhile was lettting her skirt ride up. She was pretty small at 18 with hardly any tits but I couldnt help but watch and get turned on. She started rubbing his cock through his shorts and I wanted tem to stop in a way but I was getting hard. Jimmy said hey man do u mind if we do this a bit more we dont mind ya watchin just let us go further. I said I dunnowould be kinda weird. come on tammy will jack u off she just kinda nodded in agreement.
