My sister

My sister 22 is a nerd you can say always studying and never dating, not into sports either. So, it was a bit of a shock when she asked me to teach her how to fuck. I'm 25 and live fairly close to the college my sister attends just under two miles away. I'm the complete opposite to my sister, I'm into sports, dating and then study. But I still graduated and got employed locally after college. Our parents ran into financial problems had to cut back on expenses which included my sister's allowance. Which wasn't a big problem for her as she rarely shopped or bought takeouts. Living nearby to me at the college she could always get a loan if she needed one. But she didn't ask and then one Saturday morning she was over at my place as usual using my internet as it was quieter than at the college she said. I'd had a late night, no success with my date, but it was only our first date. I sat drinking coffee to get me motivated, when my sister asked how my date had been. It was something she had never asked me before, I replied okay but it was only a first date. Then she asked me how many dates before I expected sex from a date. Shocked by her question at first and then said depends on the girl, but between 3 and 7. The next question really shocked me how many dates I would expect to have with a girl like her before getting sex. I was quiet for a few moments and finally said 7, then asked her why the sudden interest in my sex life. Her answer was she didn't know anything about what was expected dating as she had never dated. Expecting to date soon then I asked, no its just for possible future reference. I thought that was it, but about half an hour later she asked could I teach her how to please a man. Shocked again but asked what do you want to know. How to kiss, when to started feeling him up and what she would be expected do during actual sex. I was totally shocked at that, but before I recovered enough to ask her how she asked me to actually fuck her and take her virginity. Adding it would better with someone who has experience than someone like me who was probably getting their first fuck also. Shocked again but also aroused and not really certain she knew what she wanted. I asked how long, do you have today because proper first fuck should take a couple of hours. Thinking she wouldn't want to spend hours on her first fuck. But she was very willing to take the proper time to get the experience she wanted. With her saying she could stay overnight if required, my date the night before a nurse was working and I hadn't anything else planned. So, I agreed I'd condom and a willing girl so why wouldn't I fuck her. It's not like I'd asked her; she had asked me. So, we went to my bedroom and spend several hours having sex starting with showering together than foreplay than actual intercourse. I really enjoyed myself, got to fuck my sister three times in all with condoms no accidents. With her giving several blowjobs as well and even swallowing my sperm once. I went down on her as well. having shaved her pussy before we first showered together. The following weekend she came over as usual and I asked how she was and she said great. I decided to be a bit cheeky and asked did she want any more lessons. She smiled not at the moment thankyou I'll let you know. That night I'd a date with the nurse and we slept together. She left my place about 9 next morning had start work at 11. My sister came over that afternoon about 1 30, asked for another lesson. So, she and I showered and went to my bed she left at 6 I'd fucked her twice and had really enjoyed the sex. That was the last time we fucked, now 3 years later I'm married to the nurse and haver one son and my sister hasn't had a date yet as far as I know.
