Being My Sister’s Sperm Donor – part 2 – by Vikingwarrior32

We continued to use Sarah in our role play, fantasy. Amy in particular enjoyed imitating her during the sessions.

After a while, it became less interesting to me. I still fantasied about Sarah, especially during the long periods between fertility weeks. The nights when Sarah and Amy were most vocal I imagined being in the room and joining them. As we got close to the next fertile week I was starting to look forward to being in the moment with Amy more.

On the first night of the next fertile week, we ate a meal together and watched a bit of TV. It didn’t feel awkward anymore, we had gone through this enough for it to feel almost natural. It felt like we were all singing from the same hymn sheet, it was liberating.

I started to get excited about tonight’s session. Spending so much time with Amy made me feel comfortable.

So far we had strictly kept to the rules. Recently I began to think about those boundaries and was eager to maybe try and move them.

When it got to ten o’clock I said I was going to turn in. I kissed Sarah on the head and waved goodnight to Amy. It was a silly charade we had fallen into. It seemed more natural than Sarah organising us regimentally.

A short while later there was a knock on my door. In walked Amy in a silk dressing gown like she always. Sarah wasn’t with her, she hadn’t been since the first night. She would wait for Amy in their bedroom. I had already got undressed, laying under the covers. I had a strange feeling of excitement tonight much like the first time. For some reason, I thought tonight would be different. Amy closed the door and turned the light off, like usual, plunging the room into darkness.

I heard her dressing gown fall to the floor and felt the bed move as she sat down. Amy started, sliding her hand up the covers feeling for my legs. She was searching for the outline of my cock. I wasn’t hard yet so I reached for her hand and pulled her up to lay beside me. We lay there in the silent darkness for a while.

“What’s wrong, doesn’t he want to play?” whispered Amy in the darkness.

“Would it be ok if I warmed you up a bit for a change?” I said hopefully.

She had initiated oral sex that first night, and a few others. I had yet to do anything solely for her pleasure. She had needed Sarah to give her an orgasm after each session.

Tonight I wanted to change that. The thought of making her wet, begging me to fuck her, started to make me harden.

Amy thought for a second then shrugged. “You know the rules, no kissing that’s it,” she said mischievously.

“Sarah also said we should try and enjoy ourselves that first night remember?” I said.

“Oh yes I remember, as long as there’s no kissing I don’t see the harm,” Amy said quietly.

I started to pull the covers down and rolled onto my side. Amy was laying on her side, facing me. Our eyes were getting used to the dark. I could see the outline of her body, her sexy feminine curves and the outline of her face. Her elbow pushed into a pillow as she held her head in her hand.

My hand reached out and started lightly stroking her body. I started at her shoulder, slipping it down her side to her thigh and back up to her hip. Our faces were inches apart, I could make out her perfect features. I wanted to kiss her so badly. I kept stroking her body feeling the goose pimples rise on her skin.

Brushing the flat of my hand over her body, I caressed and massaged her skin. I firmly grasped her bum and squeezed. My cock was stirring as I felt her soft plump bum. I heard a small sigh escape Amy’s mouth, warm breath touching my face.

My hand moved back to her shoulder and I gently pushed her onto her back. I continued stroking her body. Tracing along her collar bone and sliding my fingers over her breasts. Amy was responding to my touch, her breathing was getting more pronounced. I needed to taste her but didn’t want to overstep the mark, yet.

Lightly I brush my hands over her tits, circling my fingertips around her nipples. I moved down the bed as my hand slid down her body. I looked into Amy’s eyes but she had closed them. Would kissing her breasts break the rules?

I took a chance and leant in to kiss the side of her breast. It felt warm under my lips, Amy sighed contently. I took that as a sign of consent and planted little kisses all over her chest. I slipped a nipple into my mouth and sucked. It was hard. I flicked my tongue over it, wetting it with my saliva.

Amy’s eyes stayed shut, small moans and groans emanating from those full lips. I kept my attention focused on her chest. Licking her nipples and groping her tits. I climbed on top of her feeling her body warming.

Keeping my hands massaging her breasts, I slowly slid down her body planting kisses on her skin. Amy didn’t stop me, emboldened I decided to let her decide how much fun was too much. I reached her toned stomach and stuck my tongue into her belly button. she let out a little giggle. Her body was starting to move, writhing at my touch.

I kept sliding down until my face hovered above her pussy. I tell she was starting to get wet. Sliding my hands to follow my kiss trail, I gently blew on her thighs. My hand reached for her pussy and tentatively I began probing.

“Adam, I’m not sure this is what Sarah had in mind,” Amy whispered into the darkness. She had kept her hands by her sides until now. Slowly she raised them to take over rubbing and playing with her nipples.

“Do want me to stop?” I asked as I slipped my fingers through her wet folds. Feeling her swollen clit I started to rub it gently.

“No, don’t stop,” Amy said breathlessly.

“You like my fingers?” I asked boldly

“Uh-huh,” Amy replied quietly.

II slipped a finger inside her, continuing to stimulate her clit with my other hand. Gently I slid my finger in a few centimetres and out again. She felt so warm and wet. I slipped my finger out and sucked the tip, she tasted coppery like a penny. I wanted to taste her, Amy had sucked my cock, this wasn’t any different, was it?

I stuck out my tongue and gave her pussy a little lick. Amy moaned as I kept fingering and licking her pussy. She was writhing, legs rubbing the side of my head. Her breath was deepening.

“That feels nice, kept doing that, right there,” Amy moaned.

My cock was pushing hard into the mattress, but I wanted Amy to beg for it before I fucked her.

For what felt like an age I kept licking and fingering her pussy. Warm sticky juices coated my mouth. The taste of copper danced on my tongue. Amy was moaning loudly now, her sexy toned body writhed and wriggled. Then she said it.

“Fuck me, Adam I can’t take it anymore,” she shouted desperately.

I quickly moved up and thrust my cock deep inside her. She let out a little whimper as I started pounding into her pussy. She lifted her legs and clamped them around my waist. The bed was squeaking as I thrust harder and harder. I felt my orgasm building but I didn’t want to go so soon. The whole reason for doing this left my mind. I just wanted to keep fucking Amy all night.

I pulled out sharply and tried to flip her over onto all fours.
