Seeing as noego won't spill the beans...here goes...(apologies for TMI)
There are so many approaches to take...
Oral (on her) This is AMAZING!!! to see your lady squirm with pleasure and to hear and feel her reach orgasm with you using your tongue and fingers is such a turn on
Sexting - if you are a 'What's for tea' and 'I'll be home in 15' etc kind of texter then you will have to get past any initial embarrassment of texting. Start early in the day...things like 'I've been thinking of you (insert details of the last time you had sex) and it's turning me on' Then go to '(insert details of how your DP knows you are horny..stiff nipples, wet vagina etc) because i've been thinking of you). Keep this up all day, getting more and more sexual as the day goes on...hopefully this will mean that the second bang when your DP gets in will be the front door closing!!
Explore his body - There will be erogenous zones on your DP's body. One way to find these would be to do a bit of role play. Offer him a massage pretending to be asian, eastern european (think Villanelle off Killing Eve!) whatever you feel comfortable with (obviously you have to make the time for this)...start with him lying down on his front and ask him to tell you when whatever you are doing feels good. When you get around his arse cheeks use your nails (if you have them) to gently scratch him and slightly push his legs apart...carry on with the gentle scratching around his balls. If you are getting a reaction, bide your time until you ask him to turn over. If he is hard, ignore this area for the time being, but every so often touch him there briefly. Once you have decided to go to the 'happy ending' use massage oil, but be careful if you use condoms during sex as the oil can weaken/damage the rubber.
You could also do the above with your DP blindfolded and also you could invoke a 'no touching' rule on you, but tell him first obviously.
Blow jobs - Someone once said 'there's no such thing as a bad blow job'. They're not far from the truth to be honest. Surprise him, again making sure you have the time and are not going to be disturbed. While your DP is working from home, for example....also there were some tiktok videos of women walking into a room, dropping the towel they were wearing in front of their man and watching their reactions. There may well have been other videos with a variance on this theme as well....try them, but only if you are sure your DP won't turn you down...if he does, he's an idiot!!! Also, if he is standing up, while you are licking up his shaft with the tip of your tongue, give him 'the eyes'...big, doe eyes...this works!!!!
Dressing up role play - Nurse, policewoman, schoolgirl, army girl, French maid...one of these is bound to work. Lovehoney have some great costumes with sizes to fit all at a reasonable cost.
All of the above I would class as sexual and lead to sex. For me there is nothing better that holding each other close, gently kissing and caressing each other until you make the most amazing love to each other. I would take this every day, but one of the sexual examples above every so often also works a treat!!
