A quick tuck!

Panicking, you reach beneath the blanket and pull your erection up, strapping it under the waistband of your boxers. What you forgot, in your rush, was that your mom's right hand hand remained locked on your thigh... Just centimeters away from the tip of your cock. But even so you manage to get it poking slightly out of your pants. It doesn't matter anyway since you're under the blanket, so the others won't notice.

You look to your right; Christine is very red in the face, her hands beneath her blanket, moving suspiciously between her legs. Shocked and oddly becoming more aroused at the thought of your little sister fingering herself to the hentai movie, you shift nervously and accidentally push your erection out of your pants and it pushes towards your moms soft hand! You can't move away either because your sister moved with you, leaning towards you, forcing you to remain in position lying with your cock against your mother!

She gasps and looks sharply at you, "Will..." she whispers, almost in wonder. She doesn't move a muscle, leaving your throbbing erection against the back of her hand.

The anime girl's clothes have since been torn to shreds and discarded - a massive tentacle is probing her vagina, another her asshole, two more sucking on her nipples and one licking her lips.

The tentacle at her pussy begins to slowly penetrate the struggling girl...

... Your mom's hand moves... Slowly, almost fearfully, she wraps her fingers around your tip, as if afraid of how you will react.

You can barely breathe. Your mom is biting her lower lip, glancing at you for signs of approval. And as the tentacles began **** the anime girl in every hole, she began gliding her hand up and down your length.

You look over at your sisters - Christine has mostly given up any pretense of trying to hide what she is doing, she was leaning towards you, hugging/squeezing your right arm as she quietly but noticably touched herself.

Sarah refused to give in the her sexual desires with all her will, and clenched her hands between her legs as she relished every detail of the scene in front of her.

On screen, the tentacle **** the girl's ass erupted a torrent of cum from inside her - your mother hand had sped up, giving you quite the blowjob through your pants. Christine moaned and shuddered in her seat, probably in orgasm and Sarah surrendered to her desires, her pajama bottoms were down by her ankles and her sheet was moving suspiciously.

"Are you okay, Sarah?" asked your mom, feigning innocence as her daughter blushed harder than ever. "You look a bit flushed"

"I'm fine," she shuddered, placing her hands above the blanket, to clearly show she wasn't doing anything inappropriate but failing miserably as they were obviously very wet.

"Sweetie, you look very cold," looking pointedly at her poking nipples, working your cock very hard now. "You should cover up."

A second tentacle **** its way into the girl's pussy as several more began showering her in massive amounts of cum, filling her stomach up to its bursting point. Her eyes rolled back in orgasm as the two tentacles furiously fucked her, her hands stroking a tentacle each.

You can't hold on anymore! You moan loudly in ecstasy as you spurt jet after jet of hot cum around your mom's pumping hand and your shirt, soaking the blanket and making a rather large, obvious dark spot.
