13. The waiter showed us the table where one cpl was sitting .we can see them from the back side, so we started walking towards table when we reach ne...r them they got up & turned towards us. We got shocked because they are my sister & brother in law. We just smile & went back. I & geetadid not discuss this issue. Next day when I came back from office, Geeta told me that she chatted with my brother in law & they discussed about swapping .they feel that if we are doing with others than why not. Such a hot cock! Average length even while being slightly swallowed by his chubby fat pad and thick as hell.I wrapped my hand around the base of his cock as a tear of pre cum came rolling over the round head and down the shaft. Oh my god, this is incredible! I caught the pre cum with my tongue and followed the trail up to the tip of his cock. He let out a soft moan between his snores. It tasted musky and sweet. I started slowly jerking his fat cock. He was cut but had enough loose skin to. His tongue kept swiping over her mouth, trying to pry inside. Every time Eve tried to talk, his tongue got in. He was so fast, she couldn't believe it. She'd no sooner open her mouth in protest when her mouth would fill with tongue. Every protest got cut off this way. She literally could not get a word in edgewise.Karen saw this oral tongue fucking and found it amusing, because having her mouth fucked by a dog's tongue so disgusted Eve and she couldn't wipe her mouth or block him while sitting. I was going at uncles prick like a train piston and with a loud shout he ejaculated and spunk splashed my face and body as he emptied himself. As he gasped and panted he told uncle Bob to get his clothes off so that I could suck him too and the man was soon naked for the first time. It was a good job I was still coming down from my last pleasure trip and was in a languid mood as I giggled naughtily at the first sight of his cock, fully erect yes but it was so small. I covered any show of mirth.
