Not me but my best friend; I was sleeping over his house because his older bro was sleeping over HIS friend's house. I was in his bro's bed as they shared a room with twin beds.
Room was lit from street lights, and I was woken up by voices of his brother. I peeked a look because thankfully I was already facing towards my friends bed. His bro insisted he "needed it". I pretended to sleep but I heard movement, and peeked to see friend's older brother pull his head over to far side of bed; brother standing there facing me.
I literally didn't figure out what was happening for minutes. Then the bro's hips start pumping and it dawned on me he was mouth fucking my friend. I heard my friend resist at first, but didn't understand until now.
This went on for what felt like 15 minutes. I felt bad for my friend, but watching his bro just use his little brothers mouth without any apparent concern for him got me hard. I never wanted a little bro more than then, but I didn't have one.
I realized my face was shadowed by window behind me, so I just watched without peeking after that. I was so hard watching this. Then the brother held his head with both hands and was obviously cumming. He then pulls hard on his head as he finished cumming. I realized he's cumming down this throat, OMG.
I touched my hard dick and realized my dick was poking out of my shorts, and I had a puddle of precum in the sheets. As the bro was cumming my friend sounded like he was trying to quietly argue or complain, but he was probably holding back because he didn't want to wake me up. The brother whispered 'clean it up' twice and stood there as my friend apparently must have since his head was still there.
his bro then thanks him with a sarcastic voice and turns and leaves just like that. He closes the door, not as quietly as he could have, and I pretended to wake up. I sat up, and whispered if my friend was there. He didn't respond, so I got up and went to bathroom.
I was so hard still walking to bathroom and when just about there my dick pops out of fly and I leave it. I go into bathroom and jerk off immediately. I wondered what my friend's mouth felt like and after only pumping a couple times at the sink, shot one of my hugest loads ever probably in my life. I meant to shoot into the sink but I over shot at the backsplash, and soaked everything on the sink. toothbrushes for whole family prob (5), razor, hair scrunchies, etc. ever cum so hard it hurts?
Once I came out of cum cloud, I said Fuck to myself because of the mess I made. Back then I hated how much I came normally, but get a kick out of it now. Luckily there was a laundry hamper in there, and full, so I used a dirty towel to wipe up the puddles of my cum. then used a couple of shirts and shorts to wipe off the rest, including my own dick. I clean up what showed, and left toothbrushes and the hair brush with my cum in them still probably.
I went back to room after I flushed and got into bed. my friend had moved but still played asleep. So I just laid down, my dick still throbbing. I pulled it out so it could leak my cum on the sheets instead of my shorts and fell asleep. Never talked about this with friend.
