Back in the late 70s when I Was 20 and in the Navy, my new wife Tori (she was 19 and we had been married only about a year) and I were living in an apartment off base but very close to the base. There were lots of Navy people living in the complex so it was pretty casual and family like.
I had a good buddy Pat (21) that used to come over to our house a lot. He and I worked in the same shop and we both worked the 3 to 11 shift so after work, he would come home with me and we'd sit around and watch late night tv and drink beer. Most times, my wife would already have gone to bed (with earplugs) so it'd just be me and him. It happened so much that he started just spending the night and sleeping on the couch. Many nights it wound down to he and I sitting on the couch in our underwear, drinking beer, and watching tv. We'd sometimes have a little weed to smoke too (this was before piss testing). My wife hated that so if she was up when we lit up, she left and went to bed.
As I said, she was a 19yr. old little thing, barely 5'4 and only weighted about 100lbs. No boobs to speak of. She was a nearly B I think her bra tags said. Really great tight little ass and a tasty ginger covered pussy. I would go down on her for as long as she would let me. She usually had me stop after a few orgasms cause she was ready to fuck! She had a wet sloppy little pussy and was a virgin when we met so she didn't have a lot of other experience. She was a nice little church girl growing up and didn't really have much imagination when it came to sex. I exposed her to fucking in different positions.
"Why?" she'd ask.
"Just come on." I'd say.
She reluctantly went along unless she got to liking it. It was this way she found out she loved reverse cowgirl...I taught her to rub herself while riding my dick and she'd cum like mad!
So anyway, Pat and I would get home, get out of our uniforms, and sit on the couch with a beer and a joint and she'd go to bed. She worked days so she had to get up. More than once, after smoking, we'd be sitting there talking and absentmindedly rubbing our cocks. Once, I asked him to show me his. He didn't even blink, just pulled open his underwear and out popped his cock. Average size and thickness, like me, and hard as a nail. I just leaned up, reached over and grabbed it like it was my own.
He looked at me and said, "Go ahead, jerk it if you want."
I did and it wasn't 10 pumps later and he was cumming all over my hand and his belly.
"You want me to do yours?" he asked.
I just leaned back and pulled my boxers down and let my dick stick up. He reached over and started pumping me and not long after I came too, covering his hand and my stomach. I got up and got some paper towels and got each of us another beer. We cleaned up and drank a little more before I headed off to bed and he crashed on the couch. It was like nothing weird had happened, just a jerk off session.
As you can imagine, that started a trend. We continued to do that almost every night for the next few weeks. One evening Pat told me he had passed out on the couch and forgot to pull his underwear back up or clean the cum off. He said Tori walked thru on her way to the kitchen getting ready for work the next morning and stopped and stared at him. He heard her but didn't open his eyes so as not to embarrass her or himself and make her mad. She look for a bit then got her coffee and came back a looked some more. When he realized she was staring at him, he started to get hard. Once that happened he heard her gasp and then leave to go get ready for work.
As he was telling me this, I started to get hard thinking about her seeing another man's cock. He noticed this too (we were having our nightly couch session while having a beer). I asked him if he jerked off about it. He said he had to to get back to sleep.
"Damn dude that makes me horny." I told him.
I started jerking my cock. He said he was too and started jerking his. I pushed his hand away and took over.
"Tell me what you were thinking when jerking off after showing your cock to my wife." I told him.
He hemmed and hawed a bit and didn't really answer.
"Let's see if this helps." I said.
I leaned over and took his cock in my mouth. I had always wanted to suck him as I had sucked a cock before and wasn't sure how to approach him. He jerked upright but didn't push me away.
"Shit man!" he said, "I didn't know you'd do that!"
I lifted off his cock, slowly letting it slip past my lips, one of those spit strings still attached between my mouth and his cock.
"There's a lot you don't know about me. Now tell me about jerking off to my wife." I said.
With that I lowered my mouth back onto his cock and started sucking and running my tongue along the underside while pushing it up toward the roof of my mouth. He moaned then started to tell me about how he was thinking how hot it would have been for her to come over and start touching his cock. I asked him if he wanted her to suck him like I was.
"Hell yeah!" He said.
Then I told him she wasn't very good and I was way better! We laughed a bit at that.
"Yeah but she has a pussy. Is it tight?" He asked.
