I had barely been able to concentrate on my lessons at college that day. I'd spent much of it with a semi hard-on just thinking about mom wanking me off that evening, and the sight of her in her underwear. By late afternoon, the ache in my balls was more than normal. I needed to cum, big time.
When I got back to our house, my heart was beating fast, not knowing quite how things would pan out this evening. Mom's car was parked in the driveway. She was home already -- she normally got in before me, because of the hours she worked.
She was in the kitchen, and called out to me as she heard me come in and slam the door shut.
"Jacob, come in here."
I walked down the hallway into our kitchen.
Mom had her head down mixing something in a bowl.
"I've been thinking about our little arrangement," she said, looking up at me, and without any 'Hello' or 'Hi'. "We'll have to organise our evenings so that we have one session as soon as you come in, one just before bedtime and then fit one in somewhere in between depending on what we've both got planned for the evening." I didn't like the tone of her voice. She was in one of her moods it seemed, and it was the last thing I expected or wanted when I got home.
"This is all very inconvenient for me Jacob. I hope you appreciate what I am doing for you," she continued, sounding really pissed off. Maybe she had been simmering all day at work, thinking about my problem and what she was having to do to help me.
"I do mom," I said, trying not to let her get to me and appease her. "It's only for a couple of weeks, hopefully," I added.
"Are you sure you've not been lying to Dr. Taylor and me about being with a girl and catching something?" she said accusingly. "If I find out after all this that you have, young man," she continued, in a threatening tone.
"Honestly, mom, I haven't," I said a little desperately, "I honestly don't know why I've got this...er...problem," I added looking directly at her.
She looked at me hard in the eyes from across the room in silence for a few seconds, and then seemed to mellow a little.
"Ok, then," she said, more calmly, apparently pacified at my response, and looking back down at the bowl she was stirring.
"Are you going to have a shower?" she said in a more relaxed tone, but sounding like she was being made to do a chore.
"Yes, mom," I said. I normally had one first thing, when I got home in the evenings.
"Well, as we need to get three specimens each evening, I think we can do one first thing when you come home, whilst you are showering. It will save time," she said.
My dick became alive as she spoke, despite the fact we had almost argued a moment ago.
"Ok," I said, and blushing a little. "I'll...er...leave my bathroom door open for you."
"Give yourself a good wash all over, first," she replied, "And then give me a call. I don't want to come in before you've had a chance to clean yourself all over properly," she continued.
"Ok, mom" I replied and turned back into the hallway and ran up the stairs. My dick was straining in my pants again.
I pulled off my jeans, t-shirt and sweater quickly, kicked of my sneakers off and removed my socks in double quick time. I wanted to cum, and cum soon -- my balls were really aching.
I left the bathroom door ajar and got into the bath, pulling the shower curtain across at the same time. Turning on the shower, I gave myself a good wash all over, including my balls and semi hard cock.
I had one of those shower's that were positioned over the bathtub with a detachable head, so you could either take a proper bath or stand at one end of the bathtub and shower, or use the head attachment in your hand. It was nice having my own bathroom attached to my bedroom.
On finishing, I turned the water off, opened the shower curtain, and shouted out loudly to mom, so she could hear me downstairs, "I'm ready mom."
As I dried myself off with a towel whilst standing in the bathtub, I thought about mom coming in here in her bra and panties, and my cock became fully hard. I was desperate to cum, but I didn't want mom to see me like this as she walked through the door. I was still a bit embarrassed about her seeing me so easily aroused, so I decided to hang the towel casually in front of my legs, hoping she would not notice that I was trying to hide my erect dick.
I heard mom come into my bedroom and then she knocked on the bathroom door, which was ajar about two inches.
"Come in," I said. My heart was beating fast.
Mom came in. She had not undressed and was still wearing the half sleeved blouse and skirt, which I had seen her in downstairs. I felt a bit disappointed. She had the semen-measuring beaker in one hand.
She looked me up and down and saw I was holding the towel, covering my crotch and legs partly. My dick jerked up again, seeing mom standing just a few feet away, with me being nude in the bath in front of her.
"Why are you holding that towel?" she said, and grabbed it. As soon as she snatched it from my hand, she saw my boner sticking out.
I blushed, still not used to her seeing me like this.
"Your cock gets hard easily doesn't it?" she said, not taking her eyes off it, and looking a little mesmerised by it. My stretched cock head, with the piss slit showing, pointed straight up towards her.
"Er...well... I guess...it's cos I'm quite young." I said a little embarrassingly, trying desperately to think of an excuse. "I can't really help it," I added, being truthful.
She licked her lips. I'd not seen her do that when she had wanked me off before.
I blushed again, not quite sure what to make of seeing her do that.
