A 17yr Olds Sexual Learning

Just an Insight into the mind of a sexully active 17yr old and his girlfriend,this is a true story from my distant past when i was trying to get my then 15yr old girlfriend to bed.Although i was far from a virgin(lost that at 15 we hadn't done much with each other. We had been seeing each other for about 3 weeks and had played around quite a lot,kissing, stroking, fingering,mauling her breasts after removing her bra one handed (which she bet i couldn't do and lost) sucking her nipples.etc etc. This one Saturday night her parents went out and left us looking after her little s****r 11yrs old,around 9pm she went to her bedroom and left us alone so we started Fondling and a lot more,i managed to remove her bra and panties and was fingering her pussy she was moaning and said "please tonight i want to do it" so i lay her back and with a little more fumbling entered her wet pussy, she had said she was a virgin but rode horses and played with herself a lot so she wasnt that tight, sliding slowly until our pelvic regions were rubbing each other (i had been reading magazines and stuff thought i knew what i was doing)after about 5 minutes i sat on the sofa and she straddled me and took me inside her and started grinding down on me within 5 minutes i shot my lot deep inside her and she squealed " Shit have you cum i'm not on the pill" Oh fuck i thought and then we heard Dads car pull up,i pulled my pants and trousers up and she ran upstairs to clean up and sort herself out and went to see her little s*s.When Mum 'n' Dad cam in she came down and acted as though everything was ok, as it was now 11.30pm they asked if i wanted to stay over on a camp bed in the sitting room of course i said Thank You that would great and that i would be gone by 9am in the morning, as they were all going off to bed my girlfriend gave me a kiss on the lips and said Thank You: Which her Mum heard and gave me a wry look. The following week i called to take her out and Mum invited me in and said she was at the shop will be back soon, she then said "I Hope she doesn't get pregnant" I stuttered stammered and nearly fell over with the shock, Mum said I know what you 2 did last week I found her Knickers at the side of the sofa and made her tell me all, She took my hand and said " It's our Secret,Dad must never ever know not yet anyway than kissed my lips and told me to go into the lounge sit down and wait for my Girlfriend.
