About a week after getting my first facial from my uncle (40), I (18) got a call from him to ask if I could come over and help him move stuff around in the garage cause they were going to have a yard sale. I said sure, obviously. I threw on a tank top and basketball shorts and headed over. When I got there, the garage was already open and he had started moving smaller stuff around. We got to work moving cabinets, desks and the old couches. The whole time I kept seeing his cock swinging under his shorts. I finally found a good time to tell him I could see him swinging around under there and joked about him needing new boxers cause his aren't doing a good job holding that monster still. He laughed and said what boxers? And pulled the front down quickly to flash his cock at me. Again, my eyes got wide and mouth dropped but laughed and he says how about we use the couch before it goes for sale. I say okay and he closes the garage door and takes off his clothes. I follow his lead and get naked too and sit on the couch. He walks up to me already semi hard and asks "are you ready?" and grabs the back of my head and pulls me in and slides into my mouth about halfway and starts slowly stroking in and out of my mouth. I could feel his 8in getting harder and longer with each stroke til he is finally hitting the back of my throat again and pushing that barrier to the side. Now I'm thinking this is gonna be like last time but he pulls out after a nice thrust all the way to his balls and holds me there for a few seconds. Me, with tears coming out and semi runny nose, he says aww I think your throat needs a rest and laughs. I'm like well yea, look at what is taking down. He pulls me up and leads me to the edge of the couch and asks if I'd ever been taken from the back and I told him yes but not with a big one like that. He says he'll only go as deep as I can take and he won't hurt me. So I agree, I kinda wanted it to hurt lol so I bend over the arm of the couch and bury my face in the cushions. I feel him spread my cheeks apart and start licking my hole which was a surprise to me but it felt great. After about a minute or two he asks if I'm ready and I nod yes. He stands up and somehow his cock feels harder than ever, and he begins to push into me. His head was nice and thick but he pushed in gently, grabbed me by my waist and started to slowly push deeper with each stroke. I could feel him throb inside of me and push deeper til I finally fully submitted and I felt his balls touch mine. I was like oh fuck he's all the way in! He started speeding up slightly with his rhythm and moaning louder. I couldn't help it so I started moaning with him, and asking him to cum inside me. He gripped my waist harder and starts to thrust harder and harder then says oh shit and I can feel his cock throb and pulse. He pulls out and tells me not to move. I stay there, feeling his load slowly drip out of my hole. He grabs an old digital camera he had tucked away and asks if he can take a Pic of his work. I laugh and say of course. He takes his pics in multiple angles and I ask him if he wants one with his cock in my mouth and he agrees. So I get down on my knees and put his cock in my mouth and he snaps a few more pics. When we get all cleaned up he says that he could've moved the garage by himself but he was hoping this would happen. I just laughed and said yea me too and that I'll help whenever he needs it. Favorite uncle for sure lol
