My hips undulated as the pleurae built faster and faster inside of me. I groaned about his cock as my throat stretched open. I could barely breathe. I... was so exciting. My vision fuzzed as my pussy clenched on my fingers. I swallowed, massaging his dick with my throat as the heel of my hand ground on my clit. I massaged his balls, the pleasure mounting inside of me. My lips brushed his curly pubic hair. Every time I breathed in through my nose, I smelled his manly musk. Fuck, she did it,. Hey, it sounded good to me.

He went on to say that he had great difficulty 'lasting' more than a few moments before he came, and that he also had a rather small cock; and that both of these things had become a point of contention between Carol and himself over the years.I just listened.

I couldn't help but wonder. She was with a couple of women I didn’t know so I just waved at her and went straight to the bar. Damn, she was looking as fine as ever! She had her hair down and was wearing a little sparkly tank top that really showed off those huge 38DD’s, even from across the room. Hiding the beginnings of the hard-on that the sight of my sister-in-law always inspired, I climbed onto a bar stool and ordered a beer. After a little while, I sensed movement out of the corner of my eye and looked up in time.
