They pull you away from the bed
From Torg Adventure
You move toward the bed, but the girls have another idea. They pull you out of your room and toward the bathroom.
Amy says, "Your fun with Lisa got us thinking how hot fucking in the shower would be."
Sam says, "We happen to know that Mom and Lisa won't be back for awhile. Mom went over to Aunt Karen's for the afternoon. She never leaves until dinner time. And we all know how long Lisa will be gone, if she's getting laid."
"Since we're having another threesome, does this mean that you two have had your 'private time'?" you ask with a shit-eating grin.
Amy beams at you as they pull you into the bathroom and close the door. "We snuck off to my room and spent some time together, before we left for the mall. Sam is delicious and enthusiastic."
Sam blushes with a smile. Images of the two of them, details filled in by watching them together with you, dance in your mind, keeping you very hard.
Amy continues, "But we've both said to each other that we aren't going to keep track of how many times we have threesomes and private time, making sure everything is even-steven. Max, you can have me anytime you want, as long as you have a condom, and Sam wants to be with me whenever I want. We're just all going to keep fucking. Does that make you happy?"
Looking at both sisters, you grin wide. "Oh, girls! That is great news!" You pull them together to kiss them both, and you feel two hands rubbing your crotch.
Sam breaks the kiss and says, "Now, stand still, Max." The two girls start pulling off your clothes. In half a minute, you're standing naked before them. "Now, sit, Max," Sam orders again. You drop to the toilet. Then the two girls start a striptease, removing the new lingerie from their sister. It's very erotic, with lots of kissing and groping along the way. Your cock is a spear pointing up from the toilet seat.
Then Sam turns and starts running the water. Amy steps up and sits on your lap. Then she fits your cock between her pussy lips and rubs up and down. You both purr to each other before kissing wildly, tongues akimbo.
"Okay, you two. Hop in." Sam steps into the shower. Amy stands and follows suit. You go next.
