We did not quite fall asleep after this amazing experience, but I have little concrete memory of the first few minutes after this explosion. I was careful not to put too much weight on you though. But because of our differences in body size you easily fitted underneath me, with my elbows touching the ground by your shoulders and my knees slightly pulled up.
After we both caught our breath you turned your head sideways and looked at me from the corner of your eyes.
"That was amazing. Just hope it is indeed the safe time of the month".
Suddenly I understood some of your earlier hesitation of going all the way like we just did, unprotected. To be honest, in the heat of the moment I had not given this much thought. But with a smile I was happy to admit that I had been "snipped" a few years ago, no need for more kids in my life. It was just the juice and no pits, like a friend of mine coined it. You physically relax after these words, I could feel the tension leave.
I was still half hard inside you, and the memory of what just happened was fresh in my mind. Gently I pulled out, and placed my warm, wet, half erection between the cheeks of your bum, where it was still slippery from oil, sweat and maybe traces of Vaseline.
"You really like that, hm" I asked innocently. "What if you were in the wrong time of the month, I wasn't snipped, there were no condoms around, and you still wanted to go all the way? Have you ever tried other methods of sex?" You looked at me curiously, and a little suspicious, but like a cat with a mouse needs to play, you could not resist the bait and had to ask.
"What do you mean?"
Without speaking I moved my penis up and down between your bum cheeks, feeling for your other opening with my tip. When I found it, your eyes opened wide in surprise, but then a curious glow came over them. And then, to my surprise you closed your lovely brown eyes, put your head back down on your arm, and went back to the sleep pretense, leaving me to stare at your lovely neck. Taking this as an invitation, I started moving up and down, stopping at the desired spot every time to give it a quick nudge. Quickly I got harder from the notion that you might play this game all the way. I moved like this for a few minutes, feeling that you were trying to relax, even gaining a little entry on some of my nudges. The thought about doing this with you quickly made me completely hard again, but I realized a little more lubrication would be a good idea.
I sat back quickly and greased my rapidly hardening dick liberally with the Vaseline that we used earlier. I know some glide is really what is recommended but we would have to make do with what we had. I then put some on my left-hand index finger, put the box aside, and gently spread your bum cheeks with my right hand. Carefully I put a wad of Vaseline on the puckered target of my desire, and then gently inserted it to move some of the Vaseline inside. I easily slid in to my second knuckle before I felt you tighten. I looked up, but you kept your head down on your arms, which I took for permission to proceed.
With my finger embedded there was no need to hold your cheeks apart, so I gently stroked your bum to make you relax. After ten seconds or so I could almost see you make the effort, and I could certainly feel it on my finger. Gently I applied more pressure, slowly moved a little deeper, and then started an in and out movement. After a minute or so I collected some more Vaseline, now on the thumb of my right hand, and after removing my index finger I inserted that digit with slightly more difficulty.
