Chapter 4

For the rest of the week, Mom came into my bedroom at close to bedtime in a robe with only panties on underneath. She took off her robe, sucked my cock enough to get it hard, and then talked to me about my day as she slowly stroked my cock. When we had said what we had to say, she sucked me off while I groped her ass until I came. She finished by telling me, “Always remember - I’m your mother, and eyes on the future.”

I really hated going to my dad’s Sunday. I loved spending all day hanging with my friends, and I loved “frank discussion time” every night. I felt like life couldn’t get any better. But I had promised, and so I went.

Sunday night, I thought about what Mom had said about Ellie looking to cheat with me again. I didn’t get that feeling at all. She seemed very happy with Dad. I really liked Ellie - when she wasn’t around Dad. And I didn’t care for Dad. All he talked about was work, which I found boring as I hadn’t held a job. The only other topic he discussed was politics, and when he did, I wished he’d talk about work.

Dad and I had ice cream as a bedtime snack. As we ate, he said, “I should be putting you to work at the business. Put you in Maintenance and have you paint. There’s always something that needs painting.”

“Let him be this summer,” said Ellie. “Let him get a year of college under his belt and then next summer have him do something useful in the office.”

“Besides, I’m here only every other week.”

Ellie said, “We wouldn’t mind you spending the rest of the summer with us.”

I shook my head. “I promised Mom I’d spend every other week with her.”

Dad said with finality, “Well, next summer, you’ll be here all summer. You’re going to work at the business, and there you’ll get a real education.”

I didn’t want to do that. I wanted to spend the next summer with Mom, having “frank discussion time” every night. But I knew what Mom would say when I told her about Dad’s job offer - take it. Eyes on the future.

I’d said with all the enthusiasm I could muster, “That’d be great, Dad.”

The next morning at breakfast, the atmosphere was much different. Ellie was clearly pissed at Dad, and Dad was doing his best to ignore her anger. Ellie stomped and glared but didn’t say a word. It was frosty between them. I found it funny that Ellie was wearing a gray long-sleeve full-zip fleece jacket on a summer morning “to handle the frostiness”.

After Dad left, I vacuumed the house. I knew Ellie would appreciate me doing it unasked, and it gave her time to calm down before she talked to me.

When I finished vacuuming, Ellie was sitting on the couch. She patted the cushion next to her and said, “Come talk to me.”

I sat down next to Ellie and asked, “You okay?”

“Yes and no. I’m still very angry at your father. Friday when he came home, he told me he’d be gone Tuesday and Wednesday night. I told him that those would be my most fertile nights of this cycle. He agreed to postpone those trips.”

Ellie suddenly spun on the couch while going up on her knees. She then threw a knee over me, so she was straddling my lap, facing me. She towered over me in that position. She looked down at me and asked, “Do you know what that bastard told me this morning?” She pulled the zipper on her jacket down a few inches.

“No idea.”

Ellie pulled the zipper down a few more inches. I could see she wasn’t wearing a bra. “He told me that he had changed his mind; that it’d be too hard to reschedule those trips. He was close to closing two big deals, and he didn’t want to lose momentum. So he’ll be gone my two most fertile days. After he promised me he’d be here.” She pulled the zip down some more so only a few inches were left unzipped. The jacket had spread open and I could now see the sides of her magnificent tits. Dad’s house had a pool in the backyard, and I had seen Ellie in a bikini many times, but I had never seen this much of her boobflesh before. The skin I could see was flawless.

“Your father doesn’t seem interested in performing his husbandly duties.” She finished unzipping the jacket, and it hung open, showing lots of enticing skin and even more boobflesh. “I told you the last time you were here how important it was to me to get pregnant this cycle.” Ellie was now holding the zipper ends of her jacket and had pulled her jacket even wider. I could see even more of her tits now. I suspect I was close to seeing the dark ring around her nipple. “I’ve been thinking of a Plan B in case your father did something stupid like this.”

Ellie put her hands on my shoulder and leaned closer. Her boobs were only a few inches from my mouth. “Jacob, I want you to do me a huge favor.” I knew I should be looking at her face, but I couldn’t resist staring at her boobs. “This has to be absolutely secret. Not the slightest slip to anyone ever about this. Promise me you’ll never tell anyone about what I’m about to ask you.”

The main thought in my head was to kiss Ellie’s gorgeous boobs. I pushed that aside long enough to say, “I promise.”

“Jacob, I want you to get me pregnant this week. I want you to fill me up this morning with your fertile spermies so that when my egg drops tomorrow or Wednesday, it’ll have a massive sea of spermies to swim through. And I want you to keep filling me with your spermies. I want to be so full of your spermies that there’s no way I won’t get pregnant. Would you like to do that, Jacob? Would you like to fill me up with your lovely spermies?”

“Um...”

Before I could say yes, Ellie continued. “You’ll have to follow my exact instructions. Some of the instructions will be to keep your father from finding out. Some of the instructions will be to increase my chance of getting pregnant. Are you willing to do everything I say this week?”

I opened my mouth to say yes. Before I could, Ellie whipped open her jacket, revealing her perfect breasts. “I’ll be your girlfriend for the week. There’ll be times when I’ll need you to wait on me hand and foot.”

Ellie had gorgeous tits. Big, though not as big as Mom’s. They had a smaller dark ring around the nipple than Mom’s, but they stood up more pertly on her chest, and her skin was flawless. More importantly, they were right in front of me.

“We’ll spend the week kissing, cuddling, and filling me with lots and lots of spermies.” Every time Ellie said ‘spermies’, I wanted to laugh. But it suited her perfectly. “But only for this week. When you come back the next time, I’ll be your stepmom again. Hopefully, your pregnant stepmom.” Ellie moved one of her tits towards my face. “Do you want to do that, Jacob?” Ellie pressed a nipple against my cheek. “Would you be willing to be my secret boyfriend for just this week?” She shifted so her other nipple pressed against my other cheek. “And keep me filled up with your lovely spermies? Would you be willing to do that for me?”

I reached out with my mouth and latched on to one of her gorgeous tits. I sucked gently on it.

Ellie stroked the back of my head gently. She asked, “Can I take that as a yes?”

I nodded my head as I continued sucking on her tit.

Ellie took off her jacket and resumed stroking the back of my head. “When you get me pregnant, you’ll make my tits even bigger. And then they’ll start making milk.” Ellie moved my cock in my shorts so that it was standing straight up, and then she squirmed forward so her crotch was pressed against my cock. She ground her crotch against mine as I sucked on her tit.

“Did you know that a man’s testosterone level and sperm count are highest in the morning? I’ve tried to convince your dad to have sex with me before he goes to work, but he doesn’t want to be late. You’ll fill me with your lovely spermies every morning this week.” Ellie dry-humped me much more vigorously. “Talking about getting me pregnant gets me so damn horny. Are you ready to make love?”

Now that Ellie wasn’t driving me nuts with her tits, I could think about what she was proposing. And I was very okay with it. As she said, Dad was failing in his husbandly duties, and I’d be stepping up to fulfill them for him. It wouldn’t be my baby I’d be making with Ellie; it’d be hers and his. I’d get all the fun of making a baby and none of the responsibility. And making a baby with Ellie sounded like a ton of fun.

I unlatched from Ellie’s tit, grabbed the back of her head, and pulled her down for a kiss. She resisted at first. I said, “I’ve always kissed my girlfriends,” and she stopped resisting. I pulled her the rest of the way to me, and she pressed her lips against mine. As we kissed, I dropped my hands down and cupped her full, firm ass. I pulled her crotch against mine and ground my cock into her some more.

Ellie broke off the kisses and hopped off the couch while grabbing my hand. As she pulled me off the couch, she said, “Let’s go to your bedroom.” Ellie guided me to my bedroom, and once she was beside my bed, she started stripping off her clothes. I watched as her magnificent body came into view.

“Get naked,” Ellie said in an amused tone when she noticed that I had been too busy watching her to undress. Once she was naked, she added lustily, “I can’t wait to feel you inside of me.”
