Dinner

It was pizza night, so your mother Lisa came back from work carrying two pizza boxes, a common one for her and Crystal and the bacon and cheddar that you split with Sarah.

Gathering in the kitchen table, the four of you ate in relative peace. But it was not an usual night.

Sitting by your side, Sarah's eyes kept wandering over you every few minutes, blushing and looking down every time your gaze met hers. And her chair got closer inch by inch...

Crystal, sitting in front of you, ate slow and sensously, her tongue gently caressing her lips and the softest moans coming from her mouth as she tasted her food, subtly pushing her chest forward every now and then. Doing a good job of getting your attention, if her growing smirk was anything to go by.

Your mother looked with a lifted eyebrow as a silent question when both your sisters looked away for a second. Feigning ignorance, you subtly shrugged. You didn't feel like explaining your new, alpha pheromones were attracting Sarah while Crystal was under the impression she was the increasingly attractive one and trying to pull you under her charm.

The elder sister chose that moment to increase her efforts, the soft skin of her foot causing you to stiffen for a second as it touched and caressed your leg. And it didn't stop there, moving upwards and forward until it was pressing on your thigh.

Noticing your growing blush and the warning glance you threw at the grinning Crystal, Sarah looked down, her eyes widening at the wandering feet growing closer to your groin before narrowing in jealousy and defiance.

Doing her best to act nonchalant, her hand settled on your other thigh, gently caressing the fabric and growing dangerously close to your stiffening bulge. Now your attention was divided between your food, your sisters and the burning pressure in your groin. Ok, that last one is not normal. Is it another effect?

Before things could go further, Lisa got up, causing both girls to retreat from your groin, something you were both relieved and disappointed about.

"You know, I'm hungry for some dessert. Sarah, why don't you grab the phone and ask for some ice cream? Crystal, it's your turn to wash the dishes. Doug, I need your help with something."

"Yes, mom," the three answered.

Retiring back to her room, Lisa turned around, a proud and knowing smile in her lips. "So, the day has finally come."

"What?"

"Oh, Dougie, you don't have to play dumb; I know what your sisters were doing. I'm not blind, and unlike half the women in the neighborhood, I do have a brain."

"Ok, leaving aside the matter of the 'bimbos' we have for neighbors-which I'm not discusing with you again-... why are you happy?" you questioned.

"You may not have noticed, but your sisters have been attracted to you for a while; and today they have finally decided to make a move! I'm just glad you are not rejecting them." She then embraced you, burying your head in her breasts.

As comfy as they were, you moved your head up to stare back at her. "So, you are ok with that? I mean, **** is kind of a bad thing..."

"When reproducing, dear; but a healthy sexual relationship is more than ok as long as you don't impregnate them. So use a condom to prevent that." Hugging you tighter, her head rested on yours, taking deep breaths. The bulge in her pants grew tighter, pressing against you. "Although... maybe one generation wouldn't cause too much trouble..."

At her slightly sultry tone and growing erection, you coughed loudly. Pressing you tighter against herself for a second, she let you go. "Anyway, family forming sexual bonds is not that strange. For example, your father spend almost more time with his sister than me before we moved together, especially after her surgery." She muttered with a slightly jealous tone.

"... Surgery?"

"What, you think that those melons of hers are natural?"
