May then looked down at my rigid cock and said “I don’t think I could take another orgasm – yet” and mum told her that it was ok and that she could learn how to suck me off. Mum then told me to stand in front of May and as I did I saw that my cock was neatly lined up with May’s mouth. She took hold of my cock, still a little sticky/slippy from shagging mum, with her hand and guided the end towards her mouth and mum whispering guidance, like ‘lick just under the head’, ‘make the head force itself in between your lips just like it would with your pussy’ etc. I could not listen to good as all I wanted to do was drive my cock down May’s throat and shag her mouth until I cum my load. May’s gorgeous mouth kept up its work until I couldn’t hold on any longer and I shot what felt like a huge load into May’s mouth, indeed my white creamy spunk was squirting out of the sides of her mouth but she was swallowing as much as she could. When I was finished I pulled my cock out of May’s mouth and she said, with spunk dribbling down her chin onto her tits, “that was incredible, I love the feel of cock in my mouth and the taste of spunk was not what I expected, but very nice”.
During all these days of teaching May and I ‘how’ mum had also taught us about all forms of contraception, sexual hygiene, diseases, safe sex, all the various positions and to be sensitive to each other’s requirements for the delight of our future partners and ourselves. Mum asked me “what should the man’s aim be in having sex?” I was at something of a loss and could only think of shooting a load of cum into a pussy. She impressed on me that before I orgasm I should make my partner orgasm at least once but preferably several times and always respect your partner no matter how little time you are together and that it is something of an honour for a man to be allowed to enter a woman’s pussy as without some control, a lot of damage could be done to her without harm to the man.
Friday came and May and I got home as quick as we could but even then mum was there before us. “ I expect you are both gagging for the shagging to start, but you can wait a little, John don’t get so frantic that you forget the first rule, May comes first” she was eyeing the tent my cock was making of my trousers. “Undress each other slowly, start with a kiss just like I showed you, and don’t forget all the kisses and caresses whilst you are undressing” we were both desperate to shag but followed mum’s directions, when May got to my cock she slid it into her mouth and stroked it in and out a few times and I suddenly shot a load into her mouth which she swallowed. I think mum noticed this and her expression was somewhat disapproving but she said nothing, and I vowed that I would get more control, and indeed over the coming weeks mum made me practice control by keeping me right on the edge of shooting my load with her hands and mouth. May and I continued until it seemed several hours later, but only 5 minutes, we were both naked and my cock was again so hard it hurt. Mum had put a towel on the chair and May sat on it and opened her legs to expose her lovely pussy with its patch of blonde hair. Even though I was desperate to shove my cock into her hole I dipped my head and slurped at her delicious slit for a few minutes until I could sense that she was close to climax then I straightened up and drove my cock full length into her. This sent her over the edge and I rammed her all through her climax and on for about ten minutes until I felt her start to cum again and couldn’t hold on any longer, so I drove my cock into her as far as I could and shot a huge load inside her. I could feel my cock pumping and May’s vagina spasming and later May said she could feel my cock pulsating inside her and that it was one of the best sensations she had felt. I suddenly noticed that the temperature in May’s pussy had risen and I felt like my cock was being burned, but it was an extraordinarily good feeling. Eventually, I pulled my cock out and watched as my spunk started to dribble out of May’s pussy onto the towel. May said, “That was incredible, how soon can you do it again?” From then until Sunday afternoon when May started her period I think my cock was inside her more than it wasn’t and I was getting to feel exhausted. We had been in bed shagging on Friday night with May on her back and me on my side with my hips under her right thigh and her left thigh in-between my legs and my cock ramming really deep inside her. May had cum several times and I had cum twice. Luckily we had put a thick towel under us to protect the sheet and mattress as we both fell asleep in that position. I woke some hours later and realised my cock had been doing overtime without me as the pool of cum was quite large. I was astoundingly still hard so I proceeded to slide gently in and out of May who woke up to a screaming orgasm and another helping of my cum. This was incidentally the only time that we had a marathon like that; we seemed to settle down afterwards.
