Mmmmmmm. I feel your semi-erect penis reach its full hardness again inside me. Ummmm... you feel so good inside me! I've waited all day for this! I sw...y my hips gently side to side, savoring the feeling of every part of you touching every part of me, then whisper in your ear... You've got some catching up to do.I nuzzle your neck and nudge your shoulder softly with mine. You roll us over staying deep inside me and now I'm on top straddling your hips. 'Now it's your turn.'I rock my hips in slow. I caressed her head while she nursed at my breast. I could not help but moan out-loud. I glanced over to see that Robert and Gary were mesmerized by the sexy scene that was unfolding. Their erections were standing straight up, as large and rigid as ever. This scene definitely aroused them. Elizabeth removed my nipple from her mouth, and gently pushed on to my back. She kissed me again, kissed and sucked on my neck, biting it slightly. She worked her way back down to my breasts, as I massaged. Then it was Cathy's turn, I kissed her soaking wet mouth as I took her panties off and then lay down with my mouth under her pretty little cunt as she presented her bottom to Derek. I envied my brother because I would have loved to be there where he was whilst I worshipped both her holes. I settled for her beautiful, wet pussy though and arched upwards to meet her mouth as she delved again into mine. Derek's heavy balls were on my face as he eased into Cathy's bottom and he growled softly when. ‘– the way you bust open mine!’ ‘Feels so good, too,’ mom chirped in from above, overhearing. ‘his big one in there, huh Amy? Now I pulled away and let my s****r take over as we went back and forth, taking our time tonguing mom’s bottom in turn. Then I slid a finger inside. ‘That’s it, stick it in deep!’ my s****r urged. ‘Stick one of yours in there alongside mine,’ I said, as my s****r slipped one of her own fingers up mom’s ass. We looked into each other’s eyes and smiled, our two fingers.
