It was just after my seventeenth birthday when I was shagging Joan on her bed. Her legs were up in the air and I was banging away like mad, Joan just starting to come for the third time and I was just at the end of my tether when the door opened and Joan’s soon to be 16, pretty daughter entered the room. I couldn’t stop and shot my load inside Joan as she finished her orgasm. Janet looked a little stunned for a very short time and then came towards the bed undoing her blouse. I pulled my cock out of Joan and by the time we looked Janet was down to her panties and bra. I said “Err”, Joan Said “What” and Janet said “I want that” pointing at my still stiff dripping cock, taking her bra and panties off. My cock leapt to full attention.
Janet slid onto the bed next to her mum and it was obvious that Joan had been thinking very quickly, better me than some nasty experience in a back alley. She said “OK, John will take very good care of you” so I wiped my cock dry and laid next to Janet with her in between her mum and I with my cock lying on her thigh. Janet groped a little and grasped my cock in her hand, her eyebrows raised up and she made a little ooh sound and started sliding her hand up and down. I stroked her perfect tits and tweaked her nipples whilst kissing her deeply. Then my hand slid down her chest and belly to her lovely fuzzy mound and my finger slid into her crack just in time to feel the lips swell and her lubricant to go into overdrive. I rubbed her clit and sucked her nipples until I could feel her climax starting and got into position between her legs. I then replaced my fingers with my cock and continued rubbing her clit with my cock end. Her hips lifted off the bed and my cock slid into her very tight pussy up to her hymen, this took Janet to a higher climax so I pushed my cock in breaking her virginity. I started to slide in and out and Janet was moaning in pleasure. I asked Joan, who was still there, when Janet’s next period was to start and she said it was the next day or two. I said “Good, she can have the complete experience then” meanwhile my cock was smoothly sliding in and out of Janet’s sweet pussy and she was just starting her second orgasm. Her orgasm finished and she was able to take notice when I said “It’s my turn now”, drove my cock into her pussy its full length and my pulsating cock shot a huge load of cum into her. “Oh wow,” she said “that was incredible”. I waited a little while and then pulled my cock out of her pussy onto the tissue Joan was holding to catch the spunk, blood and sex juices. Janet got another tissue, cleaned herself up and without any preamble slid down and sucked my cock into her mouth. She bobbed her head up and down and used her hand on my shaft until I shot another load into her mouth which she swallowed without a drop escaping. Over the next few months Joan and I taught Janet all that we knew.
It was about my 18th birthday that I met my first, and as it happened my only, girlfriend and we were quickly in bed. She really appreciated my sexual knowledge and I taught her all that I had learned from mum, May and Joan. We found that we were made for each other and eventually married and had two great children.
