Straight guy who just wanted a straight bud to j/o with (Part2)

Ok, so this is third time J and I have hung out. The second time was pretty much as the first. We haven't gotten together since this because of work and school. He text me asking if I had time to hang out. I actually did. He came over about 15 minutes later. We chatted and bullshit for a bit while I got everything set up in the bedroom. I went to get some towels in the cabinet. When I returned he was already naked and half hard. Watching some straight porn that he choose online. He was stroking and getting hard by the second. I got naked too and sat next to him. He asked  for some lube. I grabbed my bottle and was gonna handed to him but decided to be a bit bold. I opened it and poured it on his cock. He just looked at me and really didn't give me any type of expression. I told him that I always wanted a threesome with my "girl" and another dude. He laughed and thought that was awesome. I told him it had to be someone I felt comfortable with. Someone I could be relaxed with. J asked if I wanted just another dude to be there for her or for us both. I told him it was...whatever. He laughed and said he would volunteer. I asked if he was serious. J said he was. I asked if he would be comfortable with me "touching" him because I was curious about how it was like. He said he would ease into it. They entire time we're talking about this we're stroking our cocks. We were both rock hard. I know I was because I was looking at this hot guy stroking his cock. I don't know if he was turned on by the idea of a threesome or by the porno. I sat up and looked at him stroking his cock, look at the porno for a bit and back at him. He asked me when did I want to set this up. I told him I wasn't sure. It was just an idea. But before I could I wanted us both to be completely comfortable with each other. I didn't want something to happen and one of us freak out. He agreed with me. He's watching the porn the entire time and won't look at me. He seemed a little nervous. "I just don't want you to freak out if I grab your cock or touch you." I said while I watched him stroke his cock and he looked straight at the porn. "I wouldn't freak out with you." J said. I leaned over and grabbed the lube. I squeezed some on my hand. I leaned over and slowly reached for his cock. Looking at his face the entire time. I touched the head of it and he moved his hand. I slowly started stroking his cock with my right hand. He didn't flinch once or move his gaze from the tv. I stroked his cock slowly. He continued to watch the porn. Not looking at me once. I really wanted to lean over and start sucking his cock. But I could tell it might be too soon. I squeezed his cock from the base to the tip. A little precum came out. I use my thumb to rub it all over the head. He leaned his head back and closed his eyes. I grabbed his balls and tugged them gently with one hand while I continued stroking his cock. J just moaned and slowly started pumping my hand. I kept my hand still and let him fuck it. I grabbed some lube with the other hand I opened it. Poured a little on my hand while he kept sliding his cock in and out. He moaned some more and started fucking my hand faster. I started stroking his cock while he did. I could tell he was close. He started moaning and breathing heavily. After a few minutes he started moaning and cuming in my hand. He shot a nice load. I had his cum all over my hand. He kept his eyes closed while he laid there. I reached over to get him a towel. I put the towel next to him. I walked into the bathroom to wash my hands. But when I walked in I licked the cum from my hand and fingers first before washing them. J got dressed while I was in the bathroom.I put on some boxers while we talked a bit. We didn't talk about what I did and I thought he was freaked out. He said he would text me later while he left. After J left I put on some porn and jerked off. Which didn't last very long because I was so turned on. LOL! Actually, J did text me the next day. he asked if I had asked my "girlfriend" about the threesome. I told him I hadn't
