Sexual favour tokens

Okay so it's my boyfriends 20th birthday coming up, and for one of his fun presents I've decided to put together a cute little token book. I've already included 'enthusiastic blowjob' and a token to send me to the shop for his favourite drink. Any one else got any suggestions? He's in the army and I only see him on the weekends. Cheers ladies 😘✌🏼️
