We have been swinging with David and Jane a couple of times and met with them again last Saturday. David and Jane are in their early 60s whilst my wife Emma and I are in our early 40s. We chose David and Jane as Emma was bicurious and wanted a more experienced bisexual woman to show her the ropes and Jane was very buxom which Emma found attractive. Anyway, they are fantastic company and we have enjoyed having sex with them. We do the usual stuff, the men watch the woman having sex and then we join in. However, on Saturday, Jane introduced her strap-on and she looked absolutely stunning wearing it, the 7-inch cock standing proud and her large breasts swinging freely. Jane proceeded to fuck Emma and it was clear Emma enjoyed this immensely. She told me the feeling of her breasts against Jane's breasts whilst she fucked her felt fantastic. When Emma was being fucked by Jane in doggy position David and I took it in turns to lie underneath and lick Emma’s clit, she returned the favour and sucked our cocks. We played for a while and Jane was talking to Emma saying do you think I would like to be fucked by the strap on. Emma said she would love to see that. I agreed it might be fun to try. Emma and Jane both went to work by licking my balls, cock and arse, Jane spent a while rimming me and her fingers went into my anus. It felt great and if I hadn’t already just had an orgasm I would have definitely come again. Emma rolled a condom on Jane’s strap-on and she lubed it. I got on all fours and Jane positioned herself behind me. I edged my arse onto the strap-on and felt it slide into me. Jane started to very slowly move her hips rhythmically and the sensations going through my body were pulsating. Emma opened her legs before me and started to finger herself. My mouth lowered onto her pussy, David put his cock in Emma’s mouth and watching him come in her mouth gave me my own orgasm, which happened through the sensations of being fucked. It was a powerful orgasm. We thanked David and Jane and Emma now has her own strap-on. She has promised to fuck David next time and that should be a great watch. Jane said she wants the men next to each other on all fours being fucked by the women. Emma and Jane also said, even better perhaps they could fuck each other, who knows what will happen?
