I saw his underwear and the erection protruded further. “Now see, this is an erection of Penis. This is caused by sexual stimulation. A Person is al...ays attracted towards his or her opposite sex. And when he or she is able to see more of the opposite sex i.e. nude, he or she gets stimulated” “Son Your Penis is your Sex Organ and gets stimulated while you are watching a female getting nude, so it gets erect. It means that the Man is aroused, sexually aroused”“Why it gets erect?”“For that you. I thought I brought the contraceptive pill not to worry . first i opened her T-shirt she is wearing a pink bra . I just open her bra & gave her a lip kiss there is no movement It was conformed that she was sleeping then i started pressing his soft breast but all of a sudden she woke up . I was scared like a seen a ghost . If she tell my parents about this then what will happen . I thought of plan-B .ANJALI -What the hell you are doing with me.ME – I am sorry I cant control my feeling of sex. Hell, she wouldn't even vocalize during sex. Our sex was OK, nothing out of the ordinary,nothing erotic or mind blowing. The fact is , I fantasized and masturbated more than I got laid.Once I talked her into wearing a hem to collar button up dress, with nothing underneath. I caressed her tits, and fingered her when the road and traffic allowed.The conversation, although one sided,except for an occasional nod or giggle was hot and suggestive. Soon her dress had only one button below her naval. My eyes were glued to the sight of the wet cunts of my sisters, which they were showing to me, for my viewing pleasure. The wet hair around their pussies was partially concealing the pussy lips, which was small and cute.I smiled at them and winked. They smiled back. My elder sister, still showing her cunt to me slightly widened her legs, to give a clearer vision of her hole. My younger sis did the same.It was too much for me and I knew I need to jerk immediately.I looked at them again and came.
