Different age from different cocks but who cares. We both love each other and our mutual interest in a happy sex life since we found out how lovely it feels to be good for each other and your own body. Some of it we found out ourselves, with or without help. Some we discovered together. Although we both admit some genius behind a by herself declared virtual screen pulled the strings to start all this?
I thought of that when I saw Conny with such a happy smile on her face in her hospital bed. At the same time I had to look at her ample breasts without a bra in her skimpy nighty of which I immediately thought not being the one the best appropriate for this visiting hour.
But the visitors of the other patients didn't observe Conny so when I got in and saw her happy smile I leaned over for a hug and kissed her on her mouth and kept our lips sealed for some moments. Conny giggled and so did I.
We kissed again and our hungry wet warm tongues danced with exchanging visits in our mouths till Conny pushed me away laughing in a whisper: "Do I have to remind my slut-sis this a hospital bedroom?" I just smiled and said: "Let us make this mattress smell like our secret mattress we use at home when we never have to worry about anything". Her answer was an agitated at the same time horny groan......... 
Nothing could stop me now, the glow of my love for Conny race through my entire body and made my knees weak, my nipples hard and my cunt in turmoil. Not to speak of my dirty mind.

"I so love you, Conny", I said and with the fist of my left hand in between my thighs pressed to my emotional cunt, I finally felt again the so familiar happiness over my right hand when my beloved Conny's cunt came convulsing and squirting her wetness over my hand, wrist and arm. Again her back was arching and a loud sigh was inevitable.
Oh my, the happiness to make my sister cum again, in public was so intense, I almost pissed my chair from happiness. Conny squeezed my hand with her cunt again and asked: "Don't stop. Never. As long as we live".
I stood up from my chair and kissed her on her mouth again with a lot of tongue and this time I didn't care about the others gathered ther for the other patients. We kissed and under the blanket my fingers kissed with the same emotional happiness and horniness her other lips. The sheets felt damp...
