The three of us were in the kitchen, getting food ready, the way you do, but with Stella and I naked, and Kate not. It really didn't dawn on me until Stella started to rub my back as we chatted away to her daughter, and my cock began to twitch and swell. I have no idea what we were talking about, as Stella started to touch my ass. All I could think of was that I was getting an erection in front of Stella's daughter (something that really doesn't happen at nude parties).
I gasped for two reasons, Stella's hand was cool when it grabbed my stiff cock and, at the same time, she slipped a finger up my asshole. Kate was watching her mother wank me in front of her, and I was loving every second of it. There I was, standing naked in the kitchen, being wanked by a beautiful nude woman, who was also fingering my anus, as her pretty 19yo daughter watched her mother milk my cock.What could be better? Stella pumped my penis faster, as Kate watched closely, as my asshole was being probed deeply, and I knew I couldn't hold out for much longer. Kate could tell that I was about to cum at her mothers hands, and as I started to moan as I was being milked and probed, Kate reached for a plate, and held it in front of my throbbing dick. With Stella thrusting her finger deep inside my bum, and jerking back painfully on my shaft, I shot my load, shooting my sperm over the plate Kate was holding, and spunking half way up her arm, with a great cry of relief.
As Stella pulled her finger out of my bumhole, I kissed her and thanked her, then I kissed Kate, saying it was a great relief, who said she could see that.
