Measuring My Cum Part 8

“Go and give yourself a quick wash upstairs,” said mom after a moment. “And you might as well stay naked for now,” she added.

I got up, my now limp cock and balls flapping a bit, and started walking out of the room. I noticed mom looking at my dick as I went. Just being naked like this in front of her in our living room was exciting, and it sent a tingle through me.

I gave myself a clean in my bathroom, and in double quick time I went back downstairs again.

Mom was still topless, and wearing just her black thong and stockings and sitting on the sofa with a glass of wine in one hand. “I made a note of the amount of cum you produced, whilst you were upstairs,” she said. She’d put the empty semen beaker back on the coffee table for our next session. “It’s definitely a lot less than before — about half I’d say, which is a good sign,” she continued.

I sat down again on the three-seater sofa, picking up my wine glass as I did so. I took a sip. It felt good. We hadn’t drunk that much, so I was relaxed, but not so much that it might affect my getting a hard on.

I looked over at mom and saw her staring at me. “What?” I said.

“Oh, I was just thinking how to best stimulate you again. I think it might be a while before you can cum, no matter what we do. But perhaps we can help things along by trying a few different things, including what you said you wanted to do to me a few moments ago.”

I realised mom was referring to the crude things she had asked me to say to her. I felt a twinge in my dick just thinking about it, as mom had said she would show me her pussy and also not raised any objection when I said I’d like to see her asshole and lick it. Fuck! This was just getting better and better!

“Perhaps we can try a few games to get you going,” she said, after another pause.

“Games?” I said, confused.

“Yes, games,” replied mom. “But these are games that adults sometimes play, and I used to with your father occasionally, when we first married. I haven’t for a long time now, but perhaps you’d like to try.”

I blushed.

“Stop that blushing, Jacob,” she said sternly, noticing. “I did say you must be more relaxed with me.”

“Sorry, mom,” I replied. “I’m still trying to get used to all this.”

“Ok, well, let’s start.”

She stood up, putting her wine glass back on the coffee table.

“As you like my bottom so much, we can do something called spanking. Have you ever heard of that?”

I thought for a moment.

“Well, I think I’ve read about it, but the idea never really turned me on. I don’t mind trying,” I said.

“Good,” mom replied. “Now, I’m going to stand with my hands resting over the fireplace mantelpiece, with my ass out a bit, and I want you to give my ass cheeks a smack with your hands.”

Mom walked over the fireplace, and positioned herself as she had said. Fuck! The way her ass and legs looked in her black thong, stockings and stilettos was incredibly sexy. I felt a slight movement in my dick again.

Mom’s largish, milky white ass looked wonderful, and the wide deep curve of each buttock cheek made a fabulous shaped arch from her lower back to the tops of her thighs. For her age, her butt was still surprising well toned, although she had a bit of excess fat there, but that only added to my excitement.

I stood next to her on her left, but one step back, and gave her left buttock a light slap with my right hand. I saw the flesh of her ass cheek ripple a bit as I did so, and I enjoyed seeing that.

“Harder, Jacob, that was too light.”

“But I don’t want to hurt you mom,” I replied.

“Just do it a bit harder,” she said. “I’ll tell you if it hurts me or not, and to stop if it does.”

I slapped the same cheek again, only this time a bit harder. It actually felt a bit more satisfying.

“That’s right, Jacob” said mom, “Like that. A touch harder if you like.”

I continued, this time slapping the right buttock. I never thought I might enjoy this, but seeing the flesh of mom’s ass cheeks ripple and wobble as I did it, was quite enjoyable. Then I noticed a slight, momentary tinge of redness on the white flesh caused by my slapping and that excited me too.

“Oh, yes” said mom, appreciatively.

Fuck! She seemed to be enjoying it. It was the first time she had indicated getting some satisfaction out of our sessions.

I decided to go along with her and try to encourage her pleasurable remarks, so I said, “Do you like that mom?”

“Yes, Jacob, very much. I always used to enjoy it when your father slapped my butt. He also used to say crude things to me whilst he did it, as that used to get him going. Why don’t you try, that, your cock might respond.”

Hearing mom say this was quite a turn on. I had always thought of her as so ‘prim and proper’ in my life so far, until just a few days ago, but I never realised she used to get up to this sort of stuff!

“Sure mom,” I said.
