One night we were sitting watching TV and Mary became bored as I love the footy and she doesn’t, John isn’t really into footy as well so Mary sugg...sted that they watch a dvd ( dvd’s hadn’t been invented back then as we only had beta video’s so I’ve changed it to dvd’s so people won’t be confuced) in Johns room as it had a good telly in there and I could watch my footy on our big screen in the lounge room; I was okay with that as I hated the way she chatted during the footy show LOL. Mary. Allan rolled off of Bonnie and lay on his back beside his pretty sister."Now tell me, what's the deal with you not wearing panties?"Bonnie giggled and then she told Allan about the encounter with Steve and Tim in the girl's bathroom at school. He was astonished with his sister's account of the episode and he admired her risk taking. They chatted for several minutes and they made a pact that they would continue to have sex with each other whenever they were in the mood. Bonnie made Allan promise. .and play with them I did! After much stroking/teasing/sucking and nibbling..both nipples grew hard and she lay there with her eyes closed..but occasionally she'd murmer! Couldn't see much as we were in the dark..but she was deffinately 'enjoying it' now and when I felt between her legs..she was 'moist' again! "Slide up your nightie Joyce...I sooo want you now!" She did..and opened her legs..and pulling my erection out the front of my bottoms..a pushed my cock inside her!She now moaned. I was just lost for words. "I don't know where to start," Aunty Pam said looking me in the eye. "Your father and I have been holding these parties for the last three years. During those three years your father and I have had sex frequently - sometimes at these parties and sometimes in private. It's not a 'love thing' ... it's just that we both have sexual needs and desires, and this was a way we could both satisfy them. We do it for comfort and sexual relief rather than for love. There! Now.
