The sound of Joe's phone going off can be heard and out of habit, Joe answers it, now with his squeaky little girl's voice. "Hello." A surprised voice replies back. "Hi Lucy! Is Joe there, I need to speak to him?" Joe just says nothing and hands it to Lucy who answers. "This is Joe." The girl on the other end answers "Oh hey babe, I thought you were coming over for the day, my parents are gone." Lucy wasn't sure what to answer and so she simply replied with a "I'll be right over." The girlfriend (whom we'll name Nina) replies back "Alright love, don't keep me waiting." She hangs up and Lucy looks at her former body. "S..she wants me to come over, what do I do!?" She stammers with Joe looking a tad annoyed. "Well you said you'd be there so I guess you better go. Don't screw anything up, I love Nina." Joe tells Lucy where she lives, it wasn't too far away before Lucy gets glad in a sports jersey and jeans before heading over.
Lucy knocks on the door to Nina's home only to be met with a very attractive girl standing in front of her. She enters and closes the door behind her, trying to act natural. She had seen Joe do this before and so she tried to copy him by wrapping her arms around Nina's waist and bringing her in for a loving kiss right on the lips, one which Nina gives right back with much joy.
Nina pulls back from the kiss as she guides Lucy to her parents bedroom where she started to undress, looking at Lucy expectantly to do the same. Lucy wasn't far behind, following suit. Something had to be wrong, she can't be attracted to her brother's girlfriend! But her new body said otherwise. Minutes pass and they're soon cuddled up in Nina's parents bed, making out and caressing each other's bodies. Lucy was loving every second of it and she wanted more. Nina pins Lucy underneath her, kissing her hairy pecs and down along his abs before taking his dick into her mouth, starting to firmly suck on it with joy, going up and down at a steady pace while her skilled fingers fondle those nuts. These are all new sensations to Lucy and it already brought her over the edge and she cums into Nina's mouth, filling it with her spunk only for her to drink it down and pull back with a smirk. "That was only round one. Now round two." Lucy says as she motions for Nina to roll to her back; which she gladly does.
Lucy quickly moves on top of Nina and pushes her new cock into that wet snatch, the two lovers moaning in unison from the sensation as Lucy starts to fuck her brother's, no, now HER girlfriend, thrusting in and out of that cunt at a steady pace. She was rapidly approaching her second orgasm and before she knows it, they both yell out in unison as they both cum, Lucy's cum filling Nina up while Nina's juices coats Lucy's cock. They pant heavily from the sensation and cuddle up in the afterglow before falling asleep.
