My room mate and I had been out on a pub crawl with a bunch of friends when we realized well after midnight that we were the only ones left standing, so we jumped in a cab and went home.
When we opened the door we were hit with a wall of heat! The A/C had quit again. As we both knew what to do, I went to the fridge stripping off my shirt to get some cold ones.
When I got to the couch he was down to his underwear and rolling a fat joint. Handing him a cold one, I stripped down to my shorts too.
As we passed the joint we reviewed the evening and both wondered why we ended up home alone as there were so many hot women along for at least some of the crawl.
We compared the women we must have driven away by our excesses when I reached over the couch arm to find the lighter.
As I was saying that they just couldn't keep up with us I felt him slide his hand under the waist band of my underwear to cup my balls and say: "I guess we are the only ones that can handle each other!"
I was drunk and high enough that I didn't immediately react to the fact that another guy was caressing my sack and rolling my balls around while he pressed his thumb on my taint. My immediate reaction was to moan.
"I don't know what the fuck you think you are doing but don't stop now that feels to fucking great." I said spreading my legs to give him better access.
As he tried to push my shorts down with his free hand he said: "Neither do I but your balls hanging down looked so good I just had to see what they felt like." He replied as I felt him press his crotch against my thigh. He was as hard as a rock and felt huge. We had always been casual about dress or undress around the apartment and had seen each other going back and forth to the bath to piss or shower, but I had never seen his cock hard. It felt hot against my leg and not just by temperature.
I have had fantasies of making it with another guy but always as part of a threesome, never as a purely gay experience, but if this was going to happen I was going to make the most of it.
