Megan decided why not double down. She sprayed first Erika's crotch and then her own, but sprayed herself twice to be on the same level as Erika. Erika instantly began to pump out more cum than before, her pussy swelling to three times its original size, super red and sensitive. Erika didn't realize it but her hand had gone down to her crotch to tweak her now big clit. Megan felt something different. She moaned as she felt flesh push it's way out of her, a big cock and balls dropping out of her. She could still feel her pussy, but all she paid attention to was the quickly growing 12 inch hard-on and massive set of testes. Her balls where as large as baseballs, and she felt like she could cum just like Erika.
She went back to Erika and grabbed her legs, spreading them wide and feeling her new cock getting coated in girl cum for the first time. The sensations caused a jet of pre-cum to shoot from her cock and land all over Erika's body. She couldn't take it any more. Taking the tip of her cock in her hand, she shoved her full length into Erika with no mercy. Erika cried out in pleasure and pain, loosing her virginity to such a massive tool. The sex they had was filled with moans, cries, and the sound of cum trying to escape from Erika's cunt as it rushed past Megan's cock. In only a few minutes, Megan shoved herself in as far as she could go, emptying her load deep inside Erika. That didn't stop a massive amount of cum from leaking out of her, both her own and Megan's hot seed.
