We are not fighting or pinching each other. They might be thinking that we are now acting like grownups. Once while having dinner my sis started press...ing her right foot over mine and started moving it upwards, it was tickling but I liked it. We started playing mischief things in front of parents but being very careful. Once while eating I asked my Sis to give me her panty. She slowly removed it while eating and my parents were in front of us chatting while eating. She did not handed over to me. So we moved quickly to were there was a small room. It was a small stand . It was were they put the water storage at but under it was a small room. There wasnt a door on it but there was cardboard and a wooden pallet. So then my cousin jesus told us "this is it go in then." Diana went in first and then i was going to go in but my cousin stopped me and handed me a condom. Then i went in. We put the wooden pallet and the card board were the hole for the door was. It wasnt even a big room u had to. Thirty seconds or so and ‘Bill’ groaned and said “I’m coming” as she pulled him and then I saw some white liquid shoot out of his penis and half landed in mum’s mouth and the rest on her tits. ‘so, men come too’ I thought.‘Bill’ stood up and got dressed as mum licked up and down on Terry’s penis as Dave fucked her and nibbled her nipples. Another few minutes went by when Dave said “Terry you ready” then a few more seconds and he pulled out and they changed places.Terry pushed into mum, it was. She was running her hand in his hair as his were soon on her 44DD tits.As her unfastened her dress and pulled it down her tits dropped forward as she wasn’t wearing a bra, her nipples already erect he bent down and licked them, she sighed. As he fondled one then the other licking and sucking in turn, she laid back moaning. His left hand had now moved from her tit and onto her leg, moving slowly up the inside of her thigh, she parted her legs as he reached the top. She put her hand on his face.
