Mmm, sorry?” she said, turning to look at her, seeing her eyes stuck on the chair where Alex and Izzy were sitting. She looked, curious, not able to... see very well, but by the way her sister was now playing with her nipple through her pajamas, she was certain that she was probably also playing with herself, right there on Alex’s lap! He had to be horny too, she’d seen him before ... she assumed Izzy knew that, or could feel that. Pinching herself, she felt her nipples send twin tingles of energy. About 1 am she came by the ward was quiet, the light were dimmed for rest of the patients, she had taken off her outer shirt and was just in her t-shirt, I noticed her nipples were prominently poking at her T shirt and surmised correctly she did not wear a bra. She left as she had to check on the other patients in the ward but said she would be back "in a little while", I dozed off and was pleasantly awakened by the feel of light caress's on my cock which was standing proud and erect, I opened. While she was clearly denying that she wanted it, in the back of my mind I wanted to please her. Make this fantasy of her, Come true. I made her feel more and more comfortable and told her I shall not change even If we do it.After a few weeks she tells me, if I would ever do such a thing it would be on her birthday. We continue having sex and I do not discuss about it at all. Two months pass by and there is not a single time that I mention about the threesome to her. It is her birthday next. Hum uski dukan ke peeche wale kamre mein aaram se baith kar jee bhar pyar ki baatein karenge,” usne aage kaha.“nahin nahin! Mujhe dar lagta hai,” main phir boli.“are jaan darna kya hai! Hum kissi ko batane wale thodi hain. Aur woh to vaise bhi mera dost hai aur tumhe bhabhi manta, to woh bhala kissi ko kyon kahega? Aur phir tumhara jab bhi dil kare, tum chahe college wapis aa janan, chahe apne ghar chali jana. Kissi ko kya pata chalega,” usne daleel di.Ab man mein to mere bhi ladoo phul rahe.
