First MFM

My friend and I had sex with a girl we both know, we had both made out and fingered her in HS. We had been out at a club all dancing together and once back to his apartment we just got naked and went at it.
There was a lot of contact between he and I during the acts, we were stoned so we just went with it. She started doing some things I had seen in porn, mainly first sucking on us which meant pressing our dicks together.
Of course we double penetrated her, him in her pussy “ cause his is so much thicker.” She was being nice since all I kept thinking while all this was going was his dick was longer and thicker than mine. We start and he’s on bottom as she cowgirls him, I work my way in as he’s already fucking her and she’s vocal already. My penetration didn’t have the effect on her as I thought it would. It was my first time and it was much tighter than pussy. As I was working in I touched him and for some reason I started playing with his balls. Then while fucking our balls were in constant contact. The sex was great I came so hard. After she had to leave and was coming back the next afternoon so we could go again.
She had been gone a while and I was going to leave when he confronted me about playing with his balls. He acted real serious at first and I was so scared, I thought he would tell everyone we knew, all the guys. Then he just reached out and ran his fingertips over my abdomen just above my underwear and said he liked how it felt and if I wanted to I could do it some more, then drops his shorts. I must have just stared right at his hanging junk for a good 30 seconds before reaching under his balls and caressing them. I felt my dick begin to stir as I watched his fill up and I started stroking up his shaft asking if this was okay. He was breathing really hard by then and told me to suck his dick. I did and in a minute he was pulling back suddenly and I stroked him as he ejaculated. I also sucked on him after he shot off all over my neck, chest and chin.
Again the fear ran through me but he started stroking and sucking me, I came right away and he never came off of my dick.
I really liked it and was so relieved when he told me he had wanted to do that to me since middle school. He had been with two guys in this way before, he started telling he how it came about and I was hard again. We do it again and 69ing was so cool. I got him in my throat a little the second time and he really responded vocally. I couldn’t believe I was getting harder listening to him enjoy my mouth and a little throat.
That was 6 months ago and we have been with each other at least once a week.
