We cleaned up and got dressed, made a cup of tea and sat down round the table. May and I wondered what was going to happen, I fully expected to get a right telling off, and then Mum said “Thank you John, it’s been a long time since I had a good shag and tasted cum, it was lovely. Tell me how did you get started together?” May and I told her that it had only started the night before and that today was the second (and third) time. “Well,” she said, “you certainly seem to have the basics, and I am very pleased that you pulled out of May before you came.” At that May asked what it felt like for the man to cum inside her. For an answer mum asked May when she was due to start her period, next Monday, May answered. “That’s handy” said mum “you can find out for yourself starting on Friday night”. At our puzzled expressions she told us that for the last two days before a period it is OK to cum inside the girl as it is a safe time and she can’t get pregnant. May and I couldn’t wait till Friday night. Mum then went on “You have a grasp of the basics, but I will teach you all about sex so that your eventual partners will be satisfied, (and I’ll get some good shagging in the meantime) we will start tomorrow night.”
The next night May and I got home first as usual and I was already sucking on May’s tits when Mum arrived less than five minutes later. “Slow down” she said, “ease off John, nibble and lightly lick her nipples until I say you can move on” so I did what I was told, my cock feeling as though it was twice the size it was and harder than concrete. The next few minutes seemed like hours and my hand started to slide down May’s lovely belly but mum must have been watching and said “No, not yet, just a bit longer” May was now starting to wriggle and her hips seemed to be jumping up and down. “Now,” mum said “let your hand slowly slide down as it was doing so before, but slower, and stop just as you enter her crack. Feel for her clitoris, a hard little nub.” I was doing this and as I felt May’s clit with my finger she almost jumped up in the air. Mum said “That is a very sensitive erotic Zone, much more sensitive than nipples.” Mum saw that my finger was sliding towards May’s pussy hole and told me to keep my finger where it was and gently stroke May’s clit whilst still sucking her nipples. May seemed to be going mad by now and gasping in short breaths, her pussy lips got hotter and wetter, she groaned and pushed her groin up into my hand. “May just had an orgasm and now you can proceed to slide your finger into her, slowly”. May’s pussy felt like it was sucking my finger into it, but I kept it slow like mum said. My cock was so hard now it was painful and starting to dribble cum. Mum said, “We can’t have that” and was suddenly knelt down next to me dropping her head down to take my cock in her mouth, she sucked and slid up and down a few times and I shot a load of cum down her throat. “That tasted nice and now you will last a bit longer for May”. May had at last got her breath back and gasped “I need his cock in me, NOW”. “Ok,” mum said “but push it in slowly John, make it last”. I did so and May’s pussy felt as though it was on fire but as my pubic hairs ground against May’s the heat started to subside a little. “Now stroke in and out slowly John and hold your cum until May has cum again”.
