He does not have to make a move

...but he didn´t even have to. He forgot to cover his crotch again and Elena noticed his massive boner.

E: "You need help with that?" she asked him pointing towards his crotch.

His bulge made his hornyness quite obvious, so apparently he did not have to ask. But the unmotivated way Elena asked made it quite obvious that it felt like an unwanted duty to her. So while Franzi did not mind helping out Annie, the same did not apply to Elena helping Steve as she was not a big fan of him. But the good thing was that he did not care at all, so he just nodded his head.

Elena's hands went towards his crotch and were tugging on his underwear. Steve quickly lifted his bottom and helped her release his member. She quickly grabbed his 7 inch member and started to jack him off. After a few seconds he realized that her rather unmotivated handjob was all she was willing to invest on her own. And while eventually it would get him off, especially with that amazing show in front of him, he was not willing to let her off easily. He made the rules now.
