The first cock I ever sucked was 9X6 inches, and to my surprise, soon I had all of it, with the head down my throat! My GF and I were having an MFM with a new guy who had first really large cock she ever had. We were all nude on the bed; after some foreplay I went down on her for a while to give her a climax while she stroked his cock; and they French kissed. After about 20 minutes my neck got tired. He took over the oral and went down on her for another 15 minutes to finish the job. After she climaxed his cock was soft, so she started sucking it to get it hard. My head was near hers. She pushed his cock over to my lips and asked me to suck it while she sucked his balls. I hesitated, and then decided to try it.
As his cock slid into my mouth I was surprised at how soft and rubbery the head was. Its girth made me hold my mouth very wide, but I was able to keep my lips over my teeth so they would not hurt him. As I went back and forth, lower and lower on his cock, the head started hitting the back of my throat. Then, instinctively, I rolled over so my head was all the way back and my throat was open to his cock. He started fucking my mouth with his cock, sliding it down my throat until his pelvis was tight against my nose. I could not breath! But, he quickly pulled his cock out far enough so I could take a breath, and then pushed his cock all the way in again.
After about a dozen deep strokes, his cock was really hard; and he said that he was ready for my GF. As he pulled his cock out, she said that she could not believe I took it all and that she was going to try to take all of it too. i rubbed the head of his cock up and down between her pussy lips and on her clit several times. Then, he said that he had it; I let go of his cock; and he started easing it into her pussy. He slowly got deeper and deeper, stroking his cock in and out. She moaned each time his cock went in. When he had about six inches in her pussy she said that was all she could take. He had good control and did not try to go deeper than six inches as they fucked for about 40 minutes until he came.
After a break, we had a similar session with him but this time she had her first anal. She found that she could take all of his cock in her ass, and loved it. During a third session, I deep throated him again to get him hard, and she rode him cowboy style. But his cock would not stay hard enough time to stay in her, so we finished him off by her and I sucking on his cock until he came a third time.
After he left, she and I had some great conversations about sucking and fucking his very large cock that evening and for the next week. She was amazed that I could deep throat him and she could not, and that she could take all 9 inches anally. That MFM remains one of our most memorable swing sessions.
